RPC

ZucchiniNew7116

The blockchain size right now is 840gbs With umbrel os, and a simple RPC explorer; you will be eerily close to max. My umbrel server runs a full node, electrum, and very basic RPC explorer (no mempool) and I'm currently using 1.01TB the 2tb upgrade is coming much sooner than you think.

Why Run a Bitcoin Full Node (Technical Perspective) Running a full validating node means you independently enforce all consensus rules from genesis to the current tip, without trusting any third party. This is the only way to achieve true Bitcoin sovereignty. Here's some technical benefits: Independent Consensus  -Verification ("Don't Trust, Verify") Your node downloads and validates every block (~803 GB+ as of Dec 2025) and every transaction against the complete rule set (21 M cap, inflation schedule, script validity, sigops limits, dust rules, segwit/taproot rules, etc.). -You personally reject invalid blocks/transactions that others might accept (e.g., during past forks: SegWit2x, Bitcoin Cash, BSQ/BCash splits, Ordinals "spam" debates in 2023–2025). SPV/light clients and almost all wallets/exchanges do not do this — they trust whichever chain has the most accumulated proof-of-work (or trust their provider). Only a full node guarantees you are on the real Bitcoin chain as defined by the rules you run. Superior Privacy -When you broadcast your own transactions through your node, no third party learns which IPs are associated with which UTXOs. -You query your own node for balances/UTXOs → no surveillance company (Chainalysis, Blockstream Satellite, public explorers) sees which addresses you care about. -Running your node behind Tor or over I2P makes metadata leakage essentially zero. Censorship Resistance (Personal Level) -If pools or ISPs censor certain transactions (e.g., OFAC-sanctioned addresses in 2022–2024), your node will still relay and include them if miners mine them. -You can connect directly to miners or use techniques like sendrawtransaction with loyal peers to get transactions into blocks even under heavy filtering. Network Resilience Contribution -Each economically relevant full node increases the cost of attacks (51%, eclipse attacks, partition attacks). -Archival nodes (with txindex=1 and pruning disabled) preserve the full UTXO set history and enable re-indexing after major bugs or chain reorganizations (e.g., the 2010/2013/2018 reorg events could have been worse without archival nodes). -Nodes with open ports (default 8333) serve blocks to new nodes during Initial Block Download (IBD), dramatically speeding up network synchronization (~hours instead of days/weeks). Programmatic Access & Reliability -Direct RPC interface (getrawtransaction, gettxoutproof, scantxoutset, getblocktemplate, etc.) with zero rate limits or API-key dependency. -Critical for developers, Lightning implementations, merchants, or anyone who cannot tolerate third-party API downtime or policy changes (Blockstream, BitGo, Infura-style services have all censored or rate-limited users at various points). What Is the Actual Incentive? There is no direct financial reward for running a plain full node — no block subsidy, no fees. The incentives are non-monetary but extremely powerful for certain users. The real incentive is economic sovereignty and antifragility. The more wealth is stored in Bitcoin, the more valuable it becomes to personally validate the system protecting that wealth. This creates a positive feedback loop: as Bitcoin's market cap grows, the rational incentive to run a node increases even though the cost (~$200–500 hardware + electricity + bandwidth) stays roughly constant. In game-theoretic terms: if you hold even 0.1 – 1 BTC or more, the expected cost of not running a node (risk of being tricked into accepting counterfeit rules or losing privacy) exceeds the cost of running one. Most people who run nodes today do it because they have skin in the game and refuse to outsource validation of their life savings to Coinbase, Block, or random RPC providers. That is the real, hard incentive.

Maybe most projects shouldn’t exist then. Or at-least they’d push all risk onto users with self hosted, immutable frontends. The current system just feints security but everyone knows better and is pulling money out because the risk is full lost of funds and the reward is near zero. Code is law. That’s the whole point. The only point. All the failures have largely been from compromised centralized choke points. Whether that’s RPC, front ends, DNS. Fix the real f***ing issues and insurance premiums drop and the whole system is more secure.

The transaction success rate is currently trending toward 86 percent, reflecting a stabilization in the validator pools following the recent Agave 2.0 software optimizations. This structural resilience is a notable departure from the local outages reported earlier in the month and suggests that the network is successfully absorbing the current high-frequency demand without the same level of latency or block failure seen by market participants yesterday. ​From a technical perspective, the average non-vote transaction throughput is holding steady at over 1,000 per second. The introduction of the Agave validator client alongside the continued rollout of Firedancer components has provided a more robust foundation for high-stakes on-chain activity. While the wider market maintains a neutral momentum, the specific technical levels for late April indicate that the local bottom has been established, allowing for a cleaner lane for those utilizing priority RPC protocols. The digital pipes that were previously clogged are now operating with minimal drag, presenting a more favorable environment for collectors and traders alike. ​The current state of the blockchain is defined by a return to operational uptime and a reduction in the "ghost" transactions that plagued the mempool during the peak volatility. For those monitoring specific assets or looking to finalize signatures that were previously rejected, the present window offers the highest success probability since the start of the week. This stabilization marks a critical turning point for sovereign brands seeking to maintain consistent commerce in a high-throughput economy. ​Thank you for your time, Thomas Harrison Founder of Festive Official Brand *I am a bot, and this action was performed automatically.

I mean it's not really forgery - forgery would be somehow tricking sig validation that you have a private key that you don't. They spoofed the RPC and made layer zero sign a valid message based on a made up fact. Forgery was the mtgox hack that capitalized on ECDSA malleability.

Post is by: ksthd and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1sm873k/i_spent_february_benchmarking_solana_execution/ The meta on Solana has shifted. If you are still relying on Telegram bots to copy-trade KOLs, you are statistically guaranteed to be exit liquidity. I know, because I was one of you. In February, I decided to run a controlled experiment. I ran a standard TG bot alongside a new web-based terminal called SniperJet. My findings were undeniable. Check the attached image. That’s my actual February PNL calendar. Total Realized PNL: +$81,700 Best Streak: 21 days straight green. Winning days: 26/28. The Latency Problem: Most people don't realize the massive overhead of Telegram-based trading. Here is the chain: KOL sends message -> TG Server processes -> Bot API reads -> Bot processes -> RPC sends transaction. You’re looking at a 500ms to 1.5s+ delay in highly contested meme coin launches. By the time your buy order hits the chain, the chart is extended. The Solution: I switched 100% of my copy-trading to SniperJet.org. It’s a dedicated web app with sub-100ms execution. It hits the chain faster than the Raydium UI even loads. My entries were consistently 10-15% lower than the TG bot crowd on the same calls. How my PNL actually exploded: Stop trusting "Influencers": The "Leaderboard" feature isn't just a list. It tracks actual, verified on-chain history. I use their dashboard to copy only the top 1% of traders who have a proven 60%+ win rate over the last 30 days. No more "callers" who dump on you. Flash SOL Lending: This is the ultimate degen move. They have a built-in feature to borrow up to 10 SOL instantly. When I saw a high-conviction play but was out of liquid cash, I grabbed the loan, flipped the trade, and paid it back with profit. It’s real-time liquidity on tap. Non-Custodial Security: It’s read-only by default. My keys, my coins. I never felt comfortable giving full access to TG bots. https://sniperjet.org Happy to break down my specific KOL filtering strategy or my exit plan in the comments, but don’t DM me for alpha. Let’s talk about tech. *I am a bot, and this action was performed automatically.

Within seconds, a "Sweeper Bot" was attached to my wallet. If I sent 1 MATIC to pay for gas, the bot would drain it in the same block. My USDC was sitting there, reachable but "un-spendable". **The Battle** I tried everything. Manual transfers? Failed. Standard scripts? The bot was faster. I even tried private MEV relays, but network latency and DNS issues in the cloud were killing my timing. I felt the frustration of watching my money "trapped" while a hacker's script stood guard. **The Breakthrough: Multi-RPC Parallel Turbo** As a Senior Dev, I decided to stop playing by the hacker's rules. I built a custom Python engine designed for one thing: **Speed and Redundancy.** Instead of hoping for one connection to work, my solution: * **Parallel Broadcasting:** Dispatches the rescue transaction to 5+ high-performance RPC nodes simultaneously. **The Result** Yesterday, the script fired. While the bot was busy looking at one node, my transaction was already confirmed through another. **33.83 USDC rescued.** It wasn't just about the money; it was about winning the technical fight. **Can I help you?** If you have funds stuck in a compromised wallet (Polygon, Ethereum, or BSC) and you’ve been told "it's gone," don't give up yet. I’ve refined this "Parallel Rescue" method and I’m looking to help others who are in the position I was in. **What I need from you:** * The Public Address of the hacked wallet. * The type of token stuck. * *Note: I will NEVER ask for your seed phrase. All I need is to coordinate the rescue script execution.* Drop a comment or DM me if you’re tired of the bots winning.

While official status reports indicate the cluster remains operational, user-end simulation reverts are being documented across multiple wallet providers. This behavior is consistent with the current transitional phase of the Alpenglow consensus integration. ​Technical analysis of the current block production shows a high rate of slot-skipping, a known side effect when the network is stressed before the full Firedancer implementation. Finality windows are currently fluctuating beyond the standard 12-second target. Validators are managing a surge in priority fee requests as global trading activity remains high during the Saturday afternoon window. Users monitoring the Helius RPC metrics should expect intermittent handshake delays until the density levels stabilize below the 80% threshold. ​Thank you for your time, Thomas Harrison Founder of The Festive Official Brand *I am a bot, and this action was performed automatically.

Post is by: AdAncient6591 and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1s9i64x/report_the_retail_resilience_audit/ The digital landscape hit a wall yesterday as the industry attempted to reconcile high-performance promises with the gritty reality of retail friction. While the Alpenglow update was meant to herald a new era of finality, the actual experience for the average user was a total consensus lock. In our company alone, we watched thousands of transactions stall out, leaving a trail of failed executions that had nothing to do with a lack of effort and everything to do with infrastructure congestion. It was a perfect storm of technical evolution clashing with a system that simply was not ready for the weight of genuine traffic. ​To cure this on the user end, the solution is not to wait for the network to fix itself, but to take command of your own wallet settings. Most retail failures yesterday occurred because wallets were stuck on congested public nodes. To resolve this immediately, you must enter your wallet settings, navigate to the Solana network RPC connection, and move away from any "Custom" or "Staked" pipes that are triggering errors. For the Backpack wallet, clearing your app cache and resetting to the Default RPC is the only way to flush the digital ghosts. Furthermore, you must change your confirmation commitment from Finalized to Confirmed. This one adjustment bypasses the slowest verification layers and allows your transactions to breathe in a crowded yard. ​Traffic is no longer a metric of success but a tactical hurdle that requires elite navigation to overcome. The industry must stop chasing headline speed and start focusing on execution integrity because a brand can only remain sovereign if the pipe is as strong as the vision it carries. We have proven today that by adjusting the ritual and the settings, the 12-series art glows once again while others remain frozen. The grind we endure is not a burden but the very ritual that separates those who lead from those who merely follow. ​Thank you for your time, Thomas Harrison Founder of Festive Official Brand. *I am a bot, and this action was performed automatically.

While the broader market has seen a sea of red, the underlying strength of the top-tier assets remains undeniable. Transaction finality on the Solana network has reached a peak efficiency of 91 percent, proving that the infrastructure is finally catching up to the demand of the 2026 digital economy. For long-term holders, this period of consolidation is being viewed as a necessary reset, clearing out the noise and preparing the ground for the next major leg up. ​The Bad: Institutional Friction The primary hurdle for traders today hasn't been the price action, but the technical pipes connecting them to their capital. Coinbase spent the morning investigating a significant degraded performance incident with its Asset Recovery Tool, affecting transactions on both the Base and Solana networks. Although the exchange reported a resolution as of 10:29 PDT, the ripple effect has caused a noticeable lag in metadata updates and wallet simulations. This technical friction has left many retail investors standing on the sidelines, hesitant to commit signatures while the ghosts of the morning’s lag still haunt the RPC nodes. ​The Ugly: The High Cost of Hesitation The true ugly side of the current market is the psychological trap of the dip. As Bitcoin sits at 68,771 USD, down nearly 4 percent from its daily high, many are paralyzed by the fear of a deeper drop. This hesitation is creating a standoff between high-intent buyers and the available liquidity. Those who failed to set priority fees during the morning congestion found themselves locked out of the best entry points, proving once again that in the fast-moving world of 2026 decentralized finance, if you aren't paying for the fast lane, you aren't in the race at all. ​Thank you for your time, Thomas Harrison Founder of Festive Official Brand. *I am a bot, and this action was performed automatically.

You have less calls overall because it's indexed data, not RPC

pricklypierre13

Ah yes, Electrs needs both the Bitcoin Core RPC server and the P2P server for connectivity. I'll look at improving this in a future version of the script. In the mean time, you can set `enable_inbound_connections` to false, then after the script generates the `bitcoin.conf` file hand edit it to have these settings: listen=1 bind=127.0.0.1 listenonion=0 I believe `listenonion=0` will already be set, but you need to override `listen=1` (for Electrs) and add the missing `bind=127.0.0.1` line. That will disallow incoming TOR connections, but allow connections from Electrs but only to [127.0.0.1](http://127.0.0.1) (Electrs will need to be on the same Mac).

Post is by: AdAncient6591 and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1rtm99m/news_wire_solana_network_arithmetic_and_rpc/ Current network data indicates a widening performance gap for participants relying on standard public nodes. As of 11:35 AM EST, transaction latency is creating a persistent 150ms delay, identified as Afterglow lag. This technical friction results in failed signatures during high-velocity market activity, particularly when multiple high-liquidity wallets converge on the same metadata clusters. ​The arithmetic required to navigate this congestion is precise. To ensure a clean handshake with the validator layer, the data suggests a 0.005 SOL priority tip combined with a private RPC connection. This protocol is the established method for bypassing the public layer to secure definitive entry. This is a critical requirement for verifying ownership of high-detail 8K assets, where complex 3D depth shadowing demands stable, high-bandwidth execution. ​At present, the most significant volume is concentrating within the 10 SOL to 15 SOL liquidity tiers. These clusters are a direct result of public node bottlenecks. Success in the current cycle is determined by the precision of the handshake and the ability to execute through the priority layer. ​Thank you for your time, Thomas Harrison Founder of Festive Official Brand. *I am a bot, and this action was performed automatically.

Yeah, regular crypto APIs are built for CEX data. They struggle with DEX-only tokens, especially newer ones. For DEX price data, you have 2 options: Option 1: Query contracts directly You can query Uniswap/PancakeSwap contracts directly, but it's a pain: \- Need to calculate reserves from liquidity pools \- Handle different pool versions (Uniswap v2 vs v3) \- Manage RPC rate limits \- Build the token→WETH→USD conversion logic yourself Option 2: Use a DEX aggregator API Way simpler. Use CoinGecko API (via onchain endpoints) - it's specifically built for on-chain DEX data and it's free. Covers 30M+ tokens across hundreds of networks. The nice part is it handles the USD conversion automatically - you just ask for price in USD and it does the multi-hop conversion internally (example: token→WETH→USD or token→SOL→USD). Example endpoint: \`GET /networks/base/tokens/{contract\_address}\` Returns the token's USD price, volume, liquidity, etc. without you having to chain multiple calls. You can also get OHLCV data for charting: \`GET /networks/{network}/pools/{pool\_address}/ohlcv/day\` Take note: \- Always verify you're using the right pool address (some tokens have multiple pools with different liquidity) \- Check the \`fdv\_usd\` and \`liquidity\_usd\` fields - if liquidity is super low (<$10k), the price can be unreliable

im not overthinking. If you want you can implement a RPC Server to accept bitcoin onchain then lol Download python, download Electrum, compile, initialize the RPC Server, implement another backend to talk to that RPC server, load your seedphrase locally, generate a new address, send that new address.... See how it worse? with lightning APIs from thirdparties, all you need is to perform a requets with your bearer token.

You do know at any scale larger than a hobbyist it won't be someone manually clicking on links in a Blockchain explorer and sticking pins in a wall right? This sort of problem is exactly why computers were invented. It's a finite set of data points, split n ways. It would be an algorithm that through various means could eliminate a large percentage or all of the non relevant destination wallets. Let alone if a state or agency had additional data at the node level which by now I suspect they do run nodes and siphon additional data. Like what happened with metamask default RPC provider now collecting your IP address. That data is almost certainly acquired by interested parties

RamseyTheGoat

Appreciate the specifics, these are the kinds of takes I was hoping to get by posting here. SQLite is definitely the known weak point — I've got PostgreSQL on the roadmap but honestly at zero users right now it felt like premature optimization. The write batching keeps it viable for now but yeah, it won't survive real traffic. The "isolate the most useful case" point is the one that actually made me think. You're probably right that I spread too wide too fast. The fee analysis is the piece that's actually differentiated — most APIs just hand you the raw estimatesmartfee number, this one combines multiple targets with mempool state to tell you whether to send now or wait. Everything else is mostly thin RPC wrappers that exist because they were easy to add, not because anyone asked for them.On the module count, fair. Some of those are intentionally split out because they have their own threading (usage buffer, circuit breaker) but I could probably consolidate a few of the simpler ones. Thanks for taking the time man, genuinely helpful. im just testing out my tools and trying to learn and actually launch something. you think there's room for a new bitcoin api agent tool and what areas you think it should lean into?

ReceptionSmall9941

For routing, I’ve found aggregator depth plus failover RPC quality matters more than any single UI, especially during volatility spikes. If you’re comparing stacks, track realized slippage versus quoted fills over a few weeks—execution quality differences become obvious quickly.

ReceptionSmall9941

If Binance is asking for a Bera-compatible receiving address, try a wallet that supports custom EVM networks and manually add Berachain RPC, then use that wallet address for the refund. Before sharing the address, ask support to confirm the exact token contract on Bera so they return the correct asset.

You can (and should) run an Ethereum node at home on very cheap hardware (e.g. a Raspberry Pi 5) so there is no need to rely on a 3rd party RPC... https://ethereum-on-arm-documentation.readthedocs.io/en/latest/overview/supported-hardware.html

good catch. think of it like this: the Priority Fee is the bribe to the block leader, but the RPC is the post office. if the post office is on strike, it doesnt matter how high the bribe is—your letter never even reaches the leader. if you're on a laggy node, you're essentially sending transactions into a black hole. refreshing the dApp or switching to a private endpoint is usually the only fix

Wait, I’m a bit confused. Does increasing the 'Priority Fee' actually help if the RPC is lagging? I’ve tried cranking it to 'Turbo' on Phantom and it still hangs

Lol not solana 😂 ​Solana has gone "dark" more than any other top-ten blockchain. ​Sept 14, 2021 (17 Hours): The first "big one." A bot attack during the Grape Protocol IDO overwhelmed validators with 400,000 transactions per second, causing the entire network to fork and stall. ​June 1, 2022 (4.5 Hours): A bug in the "durable nonce" transaction feature caused a consensus failure. ​Sept 30, 2022 (6 Hours): A misconfigured validator produced duplicate blocks, confusing the fork selection logic. ​Feb 6, 2024 (5 Hours): A bug in the "Just-in-Time" (JIT) compilation cache caused an infinite loop, halting block production entirely. ​March 17, 2025 (2 Hours): A massive RPC node overload during a high-traffic event led to partial network degradation and confirmed "StatusGator" warnings. ​The "Shadow Outages" (2025): Throughout late 2024 and early 2025, independent monitors reported at least 9 unacknowledged disruptions where wallets and DEXs failed to process, even though the official status page stayed "green." ​🔓 Major Hacks & Ecosystem Exploits ​While some were protocol bugs, many were "ecosystem failures" that cost users hundreds of millions. ​Wormhole Bridge Hack ($326 Million - Feb 2022): The most devastating. An attacker exploited a signature verification flaw to mint 120,000 ETH on Solana out of thin air. ​Mango Markets Manipulation ($116 Million - Oct 2022): A "highly profitable trading strategy" (exploit) where attackers manipulated oracle prices to drain the treasury. ​Slope Wallet Breach ($8 Million - Aug 2022): A catastrophic security failure where the mobile wallet was sending users' private seed phrases in plaintext to a central server. ​Raydium Admin Key Hack ($4.4 Million - Dec 2022): A single admin key sat on a virtual machine without multisig protection, allowing a hacker to drain liquidity pools for four hours undetected. ​Upbit "Lazarus" Hack ($36 Million - Nov 2025): Suspected North Korean hackers exploited compromised hot wallets to steal SOL, ORCA, and JUP. ​📉 The "Bad News" Wrap-Up (2025–2026) ​The 97% Activity Crash (Q4 2025): As the memecoin craze cooled, monthly active traders plummeted from 30 million to under 1 million. Revenue dropped 5x, revealing how much of Solana's "success" was just speculative bot traffic. ​Validator Contraction: The number of active validator nodes has shrunk by 68% (from 2,500 down to roughly 800 in early 2026), raising major alarms about increasing centralization. ​The "Ghost App" Problem: Recent 2026 audits show that 75% of the 264 protocols ever launched on Solana are now completely inactive or dormant.

Breaking into crypto from computer science is actually very realistic right now, and a lot of companies hire juniors — the trick is focusing on skill direction, not just “crypto.” A few practical paths: **1. Pick an interest lane** Crypto roles usually fall into a few buckets: • Smart contracts (Solidity/Rust/Move) • Backend services (Go/Python/Node) • Infrastructure (DevOps, validators, RPC, indexing) • Security (audits, fuzzing, tooling) Having one “lane” looks better than applying to everything. **2. Build 1–2 tiny projects** They don’t need to be perfect. Small things like: • indexer script that tracks on-chain data • simple smart contract with tests • Telegram bot that queries blockchain • command line tool that interacts with an RPC Recruiters care more about “can you ship things” than certificates. **3. Contribute to open source** Crypto is open source heavy — good beginner places: • GitHub issues for wallets • RPC libraries (ethers.js, [web3.py](http://web3.py) etc.) • Node tooling Even documentation contributions count. **4. Job boards that actually hire juniors** Legit sources: • CryptoJobsList • [Web3.career](http://Web3.career) • RemoteOK (search blockchain) • [Simplify.Jobs](http://Simplify.Jobs) (search crypto) • AngelList / Wellfound Avoid random Telegram job channels. **5. Confidence** If your relative is sharp, they’re already ahead. Most crypto teams are small and value: • curiosity • ability to learn fast • shipping things over formal credentials. Last note: mindset matters. The space rewards people who experiment, even if things break. Tell them to keep building small and public — it compounds. Hope that helps.

You create transactions directly, using private keys and the blockchain API. Your wallet remains under your control, with no intermediaries. How it works A private key is your "password" for signing transactions (never reveal it!). UTXO model: BTC isn't a balance, but a set of unspent outputs (UTXO) that you collect and spend. Raw transaction (Raw TX): manually generate the TX: inputs/outputs, fees, and lock time. Signature: sign the transaction with your private key. Submit to the network: broadcast the signed TX via a node or API (e.g., BlockCypher, Bitcoin Core RPC). Automation tools (CLI/code): Bitcoin Core (bitcoin-cli): send TX via the command line. Python + libraries (bitcoinlib, bit): scripts for multi-line transfers. Node.js (bitcoinjs-lib) — software build and signature for TX

Bitcoin Core has an extensive command line interface and a similarly comprehensive RPC interface. The docs are freely available at bitcoincore.org

Yes, for many purposes using an Ethereum rollup is a sensible choice. Each of the L2s you have listed settles to Ethereum L2, meaning your transactions are as secure and irreversible as if they happened on mainnet, and that even if the L2 team all turn evil or their entire infrastructure is vaporized by aliens, you can still withdraw your assets back to mainnet, just by making specific L1 transactions. And you can even run nodes for most rollups on low cost hardware (like a Raspberry Pi 5) so you can connect directly to the L2 and not have to worry about RPC's monitoring transactions or proxies being turned off or whatever: https://ethereum-on-arm-documentation.readthedocs.io/en/latest/running-a-node/layer-2.html Obviously general purpose rollups are not the best solution for everyone, so if you are anticipating a high throughput for your application or need specific local regulations you can always spin up your own rollup, which is what Robinhood, Sony, Deutsche Bank etc have done. But after all that, for high value settlement it is clear that Ethereum L1 is still by far the best choice... * There is almost twice as much value in stablecoins on Ethereum L1 as on every other chain combined: https://visaonchainanalytics.com/supply * There is more than twice as much value in DeFi on Ethereum L1 as on every other chain combined: https://defillama.com/chains * There is almost twice as much value in RWAs on Ethereum L1 as on every other chain combined: https://app.rwa.xyz/networks In all 3 of those metrics, all the rollups are included in the 'every other chain combined' category... if you wanted to count L2s settling to Ethereum mainnet as part of Ethereum's data then of course the dominance would be even higher!

https://bitcoincore.org/en/2026/01/05/wallet-migration-bug/ Wallet Migration Failure May Delete Unrelated Wallet Files In Bitcoin Core 30.0 and 30.1 We have become aware of a wallet migration bug introduced in Bitcoin Core 30.0 and 30.1. Under rare circumstances, when the migration of a wallet.dat file fails, all files in the wallet directory may be deleted in the process, potentially resulting in a loss of funds. A fix is forthcoming and will be released as 30.2, but out of an abundance of caution we have removed the binaries for affected releases from bitcoincore.org. At this time, we ask users to not attempt wallet migrations using the GUI or RPC until v30.2 is released. All other users, including existing wallet users, are unaffected and can keep using existing installations. Specifically, it requires the presence of a default (unnamed) wallet.dat file, which has not been created by default since 0.21 (released 5 years ago), that fails to be migrated or loaded. One condition that may trigger this is when pruning is enabled, and the wallet was unloaded while pruning happened. Wallet Migration Failure May Delete Unrelated Wallet Files In Bitcoin Core 30.0 and 30.1 was published on January 05, 2026 .

We might be talking at cross purposes here. You are referring to execution tools (like Telegram bots) that streamline manual trading or sniping. I agree those are faster than a standard UI. My comment was specifically addressing "automated trading bots" or "copy-trading algos" where the bot makes the decisions. In that context, my point on market mechanics stands. If a specific algorithm becomes ubiquitous, the alpha disappears because everyone tries to front-run the same signal. Even with the manual TG bots you mentioned, the logic holds somewhat. If everyone uses the same "fast" bot to snipe the exact same contract launch at the same second, you end up in a gas war where only the miners or the fastest RPC node wins. It is not about principles; it is just how order books and liquidity pools function.

>L1 is the Clients you obviously have no idea what you are talking about here. I'm factoring in gas limit and block time, hence why I just "not simply just (keyword) the clients". I'm describing why Ethereum isn't (currently) scalable; I never said it can't scale. Please reread my posts if you need to. >OP is saying EVMs can reach solana scale but dont purposely so average participants can still run a local RPC. Yes, hence why I mentioned some like Sonic and Hyperliquid (also chains like Sei, which are very similar to Solana). Again, I don't deny Ethereum can't/won't scale, I simply said it doesn't scale. It's literally the whole point of the rollup-centric roadmap.

It really seems crazy to me how many people recommend (and presumably use) online portfolio trackers... has no one learned anything about how the internet works over the last decade? These platforms are inevitably going to be harvesting and selling data on your assets, linked to your IP address, which then gets combined by data brokers with all the other info that has been gathered up on you. We have known since the Cambridge Analytica scandal in 2016 that 'manipulation as a service' companies use this data to build psycological profiles of users, specifically identifying emotional vulnerabilities and exploiting them for not just financial but political and geopolitical gain. So with that in mind... why on Earth would you voluntarily give them live data on your trading habits and which scams you fall for? If you want a portfolio tracker then pick one like Rotki, it runs locally (i.e. on your computer) and is open source, so completely privacy-friendly. Nothing gets sent to anyone else's servers, no one knows what you have. Rotki even lets you connect to your own nodes if you run them, so blockchain queries aren't being leaked to your RPC. I know this sounds like an advert, but my only association with Rotki is that I've used it for... well almost since it existed. The basic version is free but I pay for premium mostly just to support the devs. It was created by Lefteris, one of the real OGs, who was involved in rescuing funds from the original DAO hack. It's a tool like Safe Multisigs that I think most people who have been in the space a long time use, but because it doesn't have a token or pay influencers to promote I guess newbies don't hear about it.

I'm not a programmer, but I messed with RPC to make Discord show what I am playing. Best Wallet worked for me quietly when stuff touched chains, so I did not fiddle with settings there. For Discord, you make an application in the developer portal, grab the ID, then run a presence script. I stick to guides from known places.

> Do you know a way, be it a platform or software, that allows me to track (in a safe and privacy-friendly way) multiple wallets and CEX account in an unified way? As far as I know Rotki is the only tool that offers what you are looking for. https://rotki.com/ It runs locally (i.e. on your computer) and is open source, so completely privacy-friendly.

The basic version is free, and if all you are doing is moving assets with simple transfers then that is all you will need, however if you try it and find it useful then you can always upgrade to premium just as a way to throw the devs some income (I'm not associated with the project in any way other than using it, but just recognize that this entire industry relies on open source software and yet the people who build it rarely get the anything like the financial rewards that memecoin shills or rich VCs extract from the ecosystem.

Block time totally matters for user experience. There's a huge difference between 0.5s and 2s. **What matters just as much as block time is RPC latency**. Unless you're running your own node, you're connecting to the blockchain through a server's RPC. For the longest time, I used to play Sunflower Land using Metamask and its default RPC. Every on-chain action usually took 2-5s to execute on both Polygon PoS and on Base L2, and sometimes I had to refresh the screen due to how slow it was. The first time I switched to Rabby wallet, I was shocked that the game action registered as soon as I lifted my finger off the mouse button. The actions were instant. I was still using Base L2, but Rabby's UX and its RPCs were so much faster than Metamask's that it felt 10x faster. So I'm pretty sure the game is looking at the mempool instead of waiting for the block to submit. In any case, there's a huge difference in user experience between 0.5s and 2s. > can you actually feel the difference between 0.1s and 0.4s Probably not unless you're using a dApp that needs extremely low-latency. I don't think differences under 0.5s are noticeable. At that point, the RPCs are much more important than the block times.

There are about 12,000 active Ethereum nodes. Of those only about 17% are hosted with cloud providers like AWS, Hetzner, OVHCloud and Google Cloud. https://nodewatch.io/ If all of Amazon's servers went offline only about 7% of nodes would be down. That would make no impact whatsoever on the network, it would only mean that those node operators would need to temporarily use a different RPC to make transactions. Ethereum's nodes are run in at least 81 countries, making it one of the most resilient networks on the planet. You can see approximate locations for each node at https://chainbound.grafana.net/public-dashboards/d001850804e1454fa24852c9dd82db97 and if you look there is probably one near you. Cool huh?

I don't like bitcoin core much, it's very restrictive. I'd suggest try getting your secret key out of bitcoin core and try with a library in a programming language. Seems like \`listdescriptors\` RPC call is currently the only way to get secrets out of bitcoin core. I don't know what js/ts has in store, but signing it should not be a hard task once you have your keys.

Failed transactions are still part of the ledger. They consume compute and pay fees., so explorers and many analytics tools will count them unless you explicitly filter them out. Headline metrics (unique accounts) can be skewed by how the metric is defined. Ledger retention is operator-configurable. Validators and RPC providers can prune local ledger history (there’s a limit-ledger-size flag and other settings) archive nodes intentionally keep everything and therefore require very large storage. Saying vaidators have to store everything is not wrong, but how much storage depends on whether you run an archive node or a pruned node.

flying-fox200

Is it that easy? I've been trying to figure out how to point a Bitcoin miner at my own full node but have been having issues (Stratum vs RPC).

I think you may be talking about different things. There are: * `-assumevalid`, a configuration setting to select a block hash whose scripts/signatures are assumed valid, as well as all its ancestors. A default is hardcoded. It can be disabled using `-assumevalid=0`. * The assumeutxo *feature*, which allows manually loading a serialized UTXO set (whose hash must match a hardcoded value) through the `loadtxoutset` RPC to bootstrap quickly. If used, a full sync from scratch is still performed in the background up to the assumeutxo point to verify that the hardcoded value is correct. Assumeutxo isn't something that can be disabled. It's just an RPC (`loadtxoutset`) you can choose to use or not use. Once upon a time, there were also plans to work on P2P extensions to permit serving the UTXO set over the network. That isn't implemented, and it does not look like anyone is working on it.

Honestly, it's really easy to get Hyperliquid connected to your wallet you can simply: Go to "Drip.trade" connect your wallet. It'll ask you to add hyperliquid to your metamask wallet, because it doesn't work on Phantom. (It will automatically add the proper RPC all that information directly into metamask for you) And then from there you can literally go to OpenSea, trade any currency using their in -house bridge Or you can go to "Relay.link" I highly recommend using relay though because they have some of the lowest fees for trading and bridging

Cheapest simple path: run a pruned Bitcoin Core wallet, derive unique deposit addresses via HD (xpub/descriptors), and use a tiny hot wallet (or PSBT flow) for withdrawals; add LNbits for Lightning if needed. Concrete setup: \- Self-host bitcoind with wallet enabled and -prune. Use getnewaddress with a per-user label for deposits; confirm via walletnotify/ZMQ. For withdrawals, use sendmany or build PSBT (walletcreatefundedpsbt) and sign on a hardware wallet if you want less hot-wallet risk. \- If you prefer watch-only: import descriptors from an xpub (importmulti), derive addresses server-side, and track UTXOs; only bring online keys for small withdrawal float. \- For Lightning: LNbits is the easiest API-first option; Core Lightning or LND work too, and Voltage can host if you don’t want ops. Handle fees with estimatesmartfee and allow RBF; schedule UTXO consolidation to avoid dust. \- I’ve used QuickNode and LNbits, and wrapped bitcoind/LND RPC behind DreamFactory to expose REST endpoints with auth and quotas. Bottom line: Bitcoin Core + HD addresses + PSBT (plus LNbits for LN) keeps it simple and cheap.

Your data on Web3 is only as safe as your key management, approval habits, and the off-chain stuff you connect to. My playbook: split wallets (burner for mints, hot for daily, cold vault on a Ledger/Trezor), use Safe with 2-of-3 for anything that hurts to lose, and turn on the passphrase/25th word on hardware. Never grant unlimited approvals; set exact amounts and regularly clear with [revoke.cash](http://revoke.cash) or Etherscan’s token approvals. Use a simulator wallet like Rabby or Pocket Universe to spot drainers before you sign. Lock exchange logins with hardware keys (FIDO2), not SMS; add a carrier port-out PIN. For privacy, assume on-chain is public; if you must store sensitive stuff off-chain (IPFS/Arweave), encrypt first (Lit Protocol works). Set address alerts on Etherscan or Tenderly so you know fast if something moves. For ops: I’ve used Safe and Alchemy for wallet/RPC hygiene, and DreamFactory to expose a read-only API with RBAC to off-chain data so a compromised dapp can’t yank everything. Security comes from strict key hygiene, segmented wallets, limited approvals, and cautious infra, not the word “decentralized.

Hi! Thanks for your questions - I'll answer them one by one. Firstly, yes - PineappleDEX includes optional MEV protection built directly into the swap interface - just click the little cog icon in the right hand corner. When enabled, it routes your transactions through a MEV-protected RPC - helping shield users from front-running and sandwich attacks by private relays.

tldr; Polygon experienced a temporary delay in consensus finality due to a bug affecting Bor and Erigon nodes, disrupting some RPC services and apps. Despite the issue, the blockchain continues producing blocks, and restarting nodes has resolved problems for some validators and providers. Engineers are working on debugging and rolling out fixes. The bug impacts finality, delaying checkpoints posted on Ethereum, but core chain operations remain unaffected. Polygon assured users of swift recovery and ongoing block production. *This summary is auto generated by a bot and not meant to replace reading the original article. As always, DYOR.

Solve the trilemma? Chains like Solana are already proving existing scaling techniques are continuing to keep up with increasing demand. Burst TPS on Solana main-net already hitting over 60K and testing on multiple future client updates like hitting near 1 million TPS. That's scaling. Speed is more than TPS. Need latency, TPS, time to finality, and good infra like fast RPC services to keep up with market demand. Cardano has none of this. It scales in no way. Currently averages around 1 TPS 🤣. This update INCREASES time to finality and does nothing to solve other scaling issues besides maybe raising TPS into the hundreds. Maybe a thousand if lucky. Nothing burger as usual from this network. Stick with what people actually use. They use it because the tech scales. Really only 3-4 networks that are still relevant and only 2 that push all Web3 activity and revenue. Not hard to determine which ones do this. Cardano is not one.

My suggestion is to check the RPC port number that Knots uses. You should be able to find it in the configuration file. Google says it's 8332, but Knots may be different. Other than not, I'm not sure what would be causing this. I've never used RPC, only Electrum.

I don’t use exchanges. Instead, I have a custom Telegram bot/sniper connected to the Solana blockchain with a good RPC, allowing me full control to quickly swap into any memecoin or stablecoin. To cash out later, I use a few trusted P2P connections who convert my crypto to fiat for a small percentage fee.

002_timmy

Appreciate it! And at the risk of oversharing, since blocks continued to get produced and this was more of an RPC issue, we wanted to wait until we had full information to update people. We knew it was a problem that would get solved rather quickly, with no risk to user funds. So giving a half-update that led to more questions than answers would cause panic that was largely unwarranted. These situations are always a challenge to figure out the comms, and I'm always happy to answer any questions 1 on 1. That way, I can understand the other person's perspective and frame of mind and speak to that. Whereas with a mass message, everyone will read it differently and it wouldn't actually be productive communication

002_timmy

Mostly agree, but for me, I wanted to share information, but I wanted to share complete information, which took time as the engineers were working with RPC providers to get everything synced and allow users to transact as quickly as possible

002_timmy

I answered some questions about the delay in transactions, but transparently I didn't have all the information because the engineering team was working to fix everything so they weren't really "available" to answer all the questions the user-facing team had. I've just posted an update on the sub - [https://www.reddit.com/r/0xPolygon/comments/1meacmn/rpcs\_went\_down\_yesterday\_but\_polygon\_has\_shared/](https://www.reddit.com/r/0xPolygon/comments/1meacmn/rpcs_went_down_yesterday_but_polygon_has_shared/) The TL;DR is there was a small bug in the Heimdall v2 code because a validator dropped. This is a super rare occurrence and caused some sync issues with RPC providers. Heimdall does finality to Ethereum, Bor does blocks on Polygon. Bor continued to produce blocks, but finality was delayed. The sync issues with RPCs caused the end user to feel the pain

002_timmy

The issue was mostly with RPC providers also.

Heres what your not understanding. Ripple becoming a bank ON TOP OF XRPL enforces the idea of everyone being there own bank. ♦️SWIFT is a gatekeeper. You build within it, under its conditions. ♦️XRPL is a toolbox. You build on top of it, without permission. In a world where programmable money, machine-to-machine commerce, and open finance are becoming the norm, rigid frameworks like SWIFT are starting to show their age. SWIFT requires you to conform to its global rules, integrate through complex APIs, clear compliance checks, and pay usage fees. Every message sent is part of a larger interbank choreography. You don’t touch the rails—you request permission to use them. It’s rigid. It’s slow. But it’s standardized. XRPL doesn’t impose rules about how to use it. You interact directly with the ledger via WebSocket or JSON-RPC, and build from scratch. It’s the closest thing to financial assembly language—lean, powerful, and yours to shape. Ripple is building a vertically integrated, blockchain-native alternative to SWIFT. Where SWIFT sends messages, Ripple moves money. For enterprises that value speed, transparency, programmability, and digital asset interoperability, Ripple's stack—especially when combined with XRPL primitives—offers a forward-facing infrastructure SWIFT can’t match. SWIFT uses ISO 20022 messaging, not a settlement platform. Its new messaging format, but still relies on correspondent banks and external settlement systems like CHIPS, TARGET2, or Fedwire to actually move money. Unlike SWIFT+ISO 20022, the XRP Ledger and RippleNet combine: •Instructions (messaging) •Routing logic •Liquidity sourcing •Final settlement on-ledger This eliminates the fragmentation between message and money, because settlement is native on XRPL. XRP isn't unlike anyform of asset or digital asset before it.. when viewed through the correct lens, is not just a digital asset, not just liquidity, and not just collateral — it is all three simultaneously. That composability is what sets it apart from anything that came before in traditional finance or even in earlier digital asset models like Bitcoin. ♦️ 1. Native Liquidity: • Globally transferable • Traded 24/7 • Final in 3–5 seconds • Nearly feeless It’s not just representing liquidity like fiat or securities — it is liquidity, in pure digital form, across any border or use case. ♦️2. Built-In Collateral: • XRP can be locked in escrows with programmable logic. • XRP can be used as bond, stake, or backing without intermediaries. • XRP can collateralize stablecoins, loans, or liquidity positions directly on-ledger. This is self-custodied, real-time collateral — not dependent on external trust or third-party clearing houses. ♦️3. Instant Settlement Layer Unlike SWIFT, Fedwire, or ACH: • XRP transactions are settled directly on the base layer. • No need for layered messaging or clearing. • No intermediaries to introduce cost, delay, or risk. It’s true atomic value transfer, which means it handles messaging, verification, liquidity sourcing, and settlement — all in one atomic step. Why This Is Unprecedented?? Traditional finance splits functions across multiple parties and systems: 1. Liquidity - Banks, Market Makers 2. Collateral - Custodians, Escrow Agents 3. Settlement - Clearing Houses, Central Banks 4. Messaging - SWIFT, ISO 20022 Ripple/XRPL does all in one: 1. Liquidity - Native in XRP itself 2. Collateral - Smart-locks on XRPL via escrows, hooks 3. Settlement - Built-in to XRPL ledger logic 4. Messaging - JSON/WebSocket native transactions XRP is unlike any digital asset before, It isn’t just a cryptocurrency. It’s a programmable, settlement-grade, liquidity instrument with built-in collateral functions. XRP is what happens when you collapse an entire financial stack into one asset on one protocol.🌐 Anyone anywhere on planet earth can right now open a node and participate in the network no questions asked. XRP cant be controlled by anyone on the network. It's not a issued asset. It's a native decentralized transparent fast settlement token. Like a gumball machine you put in a coin and take out whatever you want.

You need to review the mempool-config.json file. There , see the "HOST" line in the sections "CORE\_RPC", "ELECTRUM"and "DATABASE". They all should point to the local IP of your node. In a standalone installation is 127.0.0.1. In umbrell , I believe it should be the ip of the container of each app (something in the local ip range of 172.x.x.x)

Charming-Designer944

Credentials are not needed if you use the cli from within the gui. If you want to use bitcoind (or the RPC server of the gui) + bitcoin-cli then you need to create a small.config file with some rpc credentials.

FelixAndCo

I'll try that, but if I gave the programs no datadir (as my datadir is non-standard location), tgey refused to start complaining there was no RPC credentials.

1. Because it is fun. 2. Because you want a nide to run RPC calls to 3. Because you are exploring the Blockchain. A node with txindex enabled is a powerful exploration tool. 4. Because you want your own SPV backend, not relying on others abd not exposing your wallet contents to others 5. Because you are more comfortable announcing your nodes IP than exposing your home IP when making transactions. 6. Because you want yet another server to care for, keep up to date and monitor for security and performance issues.

>If the blockchain design itself doesn't allow apps to have these bugs How do you make a VM that doesn't allow people to create bugs on top of its instruction set? That's just not a thing. Feel free to prove me wrong but "the chain shouldn't allow buggy apps to be written" doesn't make sense. >Yes, but signing a broad allowance like that required some heavy trust  It's a specific token amount for a specific contract, not particularly broad. >It's not, you not giving a reward when you actually get a chance to mint a block is goo incentive enough I don't think you've thought this through. How do you punish someone voting on two competing forks for example? There are many subtleties in correctness of proof of stake and if you don't have on-chain slashing, you need to resort to social slashing. The fact that chains without slashing haven't been attacked yet doesn't mean it's unnecessary. >its lack of utxo model means that there can be multiple transactions competing for the same account If you're thinking about something like Cardano, which restricts smarts contracts to one state update per block that a) doesn't solve the problem because other transactions can still conflict with yours and b) is a major pain in the ass because something like a Uniswap pool would only be able to allow one trade every 12 seconds. If you're worried about paying for a failed transaction, you can send it to a non-revert RPC that will drop it for you.

If you're living in the DeFi trenches in 2025, you're not alone in feeling like the "perfect wallet" still hasn’t fully arrived—but a few options are definitely getting closer to that ideal, especially for serious users juggling EVM chains, L2s, and all the usual LP/token gymnastics. Rabby is actually leading the charge right now for a lot of power users. It’s browser-based like MetaMask, but it was built specifically with DeFi in mind. The transaction simulation feature is probably its biggest win—it previews what will happen before you confirm, which helps you dodge sketchy contract interactions or unexpected token drains. It also auto-selects the right chain based on the dapp you're connecting to, so no more annoying network switching. If you haven’t given it a real shot lately, it might be worth revisiting. Frame is another wallet gaining traction, especially among the more advanced crowd. It's not quite as beginner-friendly as Rabby or MetaMask, but it’s designed to be highly secure and modular, and it's pretty lightweight on resources. It lets you run your own RPC endpoints, manage multisigs, and keep everything streamlined for gas efficiency. Great for serious governance and LP management, though it can feel like overkill if you're not into the nerdier side of DeFi. For mobile, OKX Wallet and Rainbow (which has gotten more DeFi-friendly lately) are both improving, but most hardcore users still end up defaulting to browser wallets for the full feature set. That said, newer mobile-native wallets like Zerion are stepping up with multi-chain visibility, transaction history that actually makes sense, and built-in portfolio tools.

I know there are already some evrmore dev libraries built for rpc usage and available on PyPi… built by non core devs for their projects but released for public use. Also, the core devs have a JavaScript RPC library they’re about to release on the Evrmore project GitHub. Separately, I’m working on my own Python RPC wrapper library that I’ll make available as well when it’s done. Here’s one of the projects currently being built https://evrtokenize.com I’m not exactly sure what I want to build(forward facing) but I know I want my own library, at the very least to familiarize myself. I do agree with you, the docs could be written better. Maybe that’s something I’ll work on in my free time. Whenever I get a response regarding the zero-confirmation transactions I’ll reply with what they say. Till then, take care ✌️

DonkeyAsleep7884

Since you are using a custom RPC you must be using a different chain. You need to send some gas tokens to that chain so you can execute the swap. Eg, if you have the tokens on Polygon you need to send some POL to the wallet address, or if you have tokens on Sonic you need to send S tokens to the addy etc

Wow. That is extraordinarily bad. What the hell is FIFA doing with their L1? 10 minute has to be on the FIFA application or RPC/node side since EVM blockchains are not that slow. $0.18 is way too expensive to be anything but a batch transaction unless FIFA is purposely overcharging on Tx fees.

Btw a 2 guys messaged me privately and talked something about decentralising wallet and setting the slippage up. Do you know anything about it? They sent me links on which I am supposed to connect my wallet which for obvious reasons I can not do. One of them talked about some RPC Modifier index

I got you on a ChatGPT answer if you want. This was good for me too, lots to learn. Public Electrum servers are able to return your balance in milliseconds because they don’t rescan every block on-demand like a vanilla Bitcoin Core wallet does. Instead, they maintain a continuously-updated, pre-built index of every UTXO and transaction history, stored in a high-performance database on fast hardware with tuned caches. Here are the key factors: ⸻ 1. Specialized indexing software • ElectrumX, Esplora/Electrs, and Fulcrum each build and maintain a full “address → UTXO/tx history” index as new blocks arrive. Your wallet’s balance lookup then becomes a simple database query—no full-chain scan needed.  • By contrast, when you point a wallet at a bare Bitcoin Core node (even with txindex=1), the wallet’s RPC rescan must walk every block output and check each script against your keys, which is inherently O(chain-size) and slow. ⸻ 2. High-I/O, low-latency storage • Public servers run on SSDs or NVMe drives (often in RAID), delivering thousands of IOPS so their indexer can write new blocks and serve random reads at lightning speed. Even a modest ElectrumX instance “is I/O-bound … SSD’s are definitely recommended” —and enterprise hosts use NVMe for even higher throughput. • Example (AWS testbed): • Data disk: 1 TB gp2 (3,000 IOPS) for the Electrum index • Bitcoin data: 600 GB gp2 (1,800 IOPS) for bitcoind’s block files • Result: balance queries over a cold cache complete in under 50 ms  ⸻ 3. Sufficient RAM for caching • ElectrumX is typically run with 2 GB+ of cache (CACHE_MB = 2048), and LevelDB’s own block cache (DB_CACHE ≈ 1,200–1,800 MB), so most lookups hit memory rather than disk.   • Even a single-user Electrs instance recommends 16 GB RAM to keep its embedded database hot.  ⸻ 4. Tuned software settings • ElectrumX config tweaks commonly used on public servers: COST_SOFT_LIMIT = 0 COST_HARD_LIMIT = 0 CACHE_MB = 2048 This disables internal rate-limiting and maximizes in-memory caching.  • Fulcrum sets txhash_cache=2000 to keep recent transaction lookups in RAM.  • Esplora (Blockstream’s server) uses a “constant-time caching” schema so addresses above a threshold get fully cached.  ⸻ 5. CPU and concurrency • Indexing a new block is parallelized, and query handling is asynchronous. Single-core speeds matter less once the index is built, but public hosts often use multi-core Xeons or equivalent to absorb spikes in demand.  • Your gaming-PC CPU may be fast, but if it’s paired with a spinning disk or limited DB cache, your wallet’s RPC rescan still bottlenecks on I/O and single-threaded script-matching. ⸻ How to speed up your local setup 1. Use an Electrum-style indexer locally (e.g. run ElectrumX, Electrs or Fulcrum against your node) instead of pointing Electrum directly at bitcoind. 2. Move your data directory to an SSD/NVMe, and give your indexer its own fast volume. 3. Increase DB cache in your server config (CACHE_MB, DB_CACHE) to keep more of the index in RAM. 4. Ensure your Bitcoin Core is started with -txindex=1 (if using ElectrumX/Fulcrum) or -blockfilterindex=1 (with descriptor wallets) so the indexer can pull historic data without re-scanning blocks itself. By adopting the same hardware profile (SSD + ≥16 GB RAM + decent single-core CPU) and software tuning that public hosts use, your local Electrum server will likewise return balance and history queries in milliseconds instead of minutes.

For the reasons I stated before, it's actually extremely bad practice to not segment 100k (let alone 100M, which is impossible) TPS of data. Basically every single node, RPC, and block explore now has to store hundreds of petabytes of data just because one project decided to spam the entire network. Application-specific data really needs to be segmented into an L2/L3 or the equivalent of a private channel. Imagine being a normal user, and having to sift through 100000 pages of transactions on an explorer just to find their own.

I did investigation into this topic some times ago. From Satoshi's posts, emails, White Paper and also source code one can deduce the following: First he needed a fixed final number. Next he decided for halving function for reduction. It is very basic method, and dividing by two /2 in binary notation is just shifting, so easy to code and implement (KISS principle). Then he had to choose others parameters (he preferred simple round numbers like 10, 100, 1000, etc). In prerelease version values were: 1) block time - 15 min (1/4 of hours) 2) initial reward - 100 coin 3) halving period - 100 000 blocks (around 2.8 years) On release he changed it to: 1) block time - 10 min (round number and enough time for global data propagation and sync of nodes) 2) initial reward - 50 coin (with all halvings it Sums up to 100 in total) 3) halving period - 210 000 blocks (most INTERESTING part and choice) . . here the best guess is that he first considered 200 000 but then wanted it close to 4 years (6\*24\*365\*4 = 210240 that was rounded to 210 K) as it is socially good period: average business cycle, elections, sports and olympic games - psychological based. Had the initial reward stayed 100, which would sum up to 200 then supply would be 42 millions. But thought that sounded too much so decided to go from 50 and sums up to 100, which results in 21 mil. 50 is 50% of all coins, aka converging geometric sum(s) up to 100. In early stage Bitcoin did not have any value so he tried to find middle ground in early stages (easy for people to grasp the amount) but also for later. Also in first version, it had only 2 decimal places, and then it was increased to 8 digits, that fits into 64 bit number. This had some great effects. First it meant total 16 digits (2.1 quadrillion of units) with decimal in the middle (8+8) so it had more then enough place to grow in value. It ended up with brilliant results, could also with in types Double-precision, JSON-RPC and Js-BigInt. Another parameter is: \- difficulty adjustment period - but this is not relevant for total supply (was changed from 30 days in prerelease to 14 days/2w. aka 2016 blocks And finally, for those who likes numerology and looking for meaning in numbers to mention few interesting coincidences (or not : ): \- M2 money supply at the time around 20 Trillion $ (+2 decimal digits) \- 21 Blackjack Game \- 42 answer to everything (Hitchhiker's Guide to the Galaxy), so 21 is half solution (of many problems) \- Money for the 21st century \- All mined Gold in the world can fit into a cube of approximately 21 m3 space \- 21 Fibonaci num. \- 21 = 3 x 7 -> 3 weeks \- 21 Chromosome is the smallest autosome \- Courses 21 days, 21 lesson \- 21 year adult to drink alcohol in US

This relay price cut is kinda big. How’s this math work? if it’s $14/m RPC and they do 500k RPC/d it’s only making like <$250/mo? And the price of RPCs is going down? But token will be burnt, and token is used to pay for RPC, so then price will go BACK up? COnfused lol

forgedwithai

Every project needs RPC, so if they can hit these prices and crypto continues to rip after these tariffs, that burn is gonna SEND this token. I don’t follow the “open data” thing as much, how’s that work?

Beginning_Service387

Even though it's been a while, I'll drop my take too. Scalping on CEX? Eh, it works. But on-chain is way better. I use [BananaGun ](https://bananagun.io/)to jump into fresh liquidity and get out fast. With a private RPC, it runs much smoother, especially when everyone’s rushing in on the same thing.

[https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md](https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md) What's more important is the work you do before you download blocks. Make sure you have the right configurations because a wrong config will have you restarting indexing. I guess after you're finished downloading blocks you can check rpc commands are working, run getblockchaininfo to make sure blockchain is fully synced, check connection to peers, run a test transaction.

>The last outage was in January (3 months ago), the network cracked under the load of users trying to grab $Trump at its launch. It lasted hours. RPC's are what connect users to the chain, they aren't part of the chain... Network *was* fine. It never stopped processing blocks once. > It's a lie from Solana's team as always nah, just you lying.

kipoli99

depends on the blockchain, the general step by step would include something like generate transaction data that you desire, encode it in the form appropriate to your target blockchain, then depending on the chain digital signature algorithm you need to hash the encoded transaction and sign it with your private key. Then send the transaction data with the signature, as well as the meta-data like fees and transaction parameters into the blockchain node, either via RPC or API.

Mynameismikek

The maths required to generate the hashes isn't really doable by hand, but you can use something like [Foundry](https://book.getfoundry.sh) to send transactions from a command line (particularly using the "cast" tool). For EVM, each network node has a website listening for requests which are formatted a particular way called an RPC Server - this is what Metamask (or whatever your wallet is) talks to. The specific function you call on that site is called \`eth\_sendRawTransaction\` and it accepts the bytes that make up your signed transaction. The calculate those bytes you need (1) the address of the contract you're interacting with, (2) the signature of the call you want to make on that contract (e.g. "transfer(from, to,amount)") and (3) your private key. Combining those gives a signed transaction request the chain should accept, given you meet the constraints of the contract and the chain. You also need so send a few other details, like the gas limit, but they're kinda secondary. This is how a hardware wallet works. You send the contract address, the call signature and the parameters and it gives you the bytes back you send to eth\_sendRawTransaction.

No_Shower3743

Yes it can be done. I've sent thousands of transactions using Python. ChatGPT can write the code for you. You will need access to an RPC server to send your transactions to, some are free as well or run a node yourself.

Logical_Lemming

Not really. By default, we all submit our transactions to the mempool, where they sit until a miner chooses to include them in a block. Everyone can see this mempool and look for opportunities to sandwich attack people. No hijacking necessary. You can protect yourself by using custom RPC services like Flashbots Protect, which send your transactions straight to block builders (who generally promise to give you fair execution, trust me bro style) instead of publishing them to the mempool.

tldr; Cybersecurity researchers have identified a malicious Python package, 'set-utils,' on the PyPI repository that stole Ethereum private keys by impersonating popular libraries. The package targeted Python-based blockchain applications, intercepting private keys during wallet creation and exfiltrating them via Polygon RPC transactions to evade detection. It was downloaded 1,077 times before being removed from the registry. The attack highlights risks in software supply chains and the need for vigilance in package installations. *This summary is auto generated by a bot and not meant to replace reading the original article.

Why not just run a full node wallet for each chain you are interested in, no more secure way to interact with a blockchain. Just use some kind of way to manage the keys offline, like a hardware wallet, or just use RPC to build your own.

HSuke

Just playing devil's advocate. Most end users don't run participating nodes anyways. They use a 3rd aprty API to connect to a large centralized RPC node which then interacts with the blockchain. You'd need $100M of Bitcoin mining equipment or Ethereum staking to have a decent chance of producing 1% of blocks, so participating in block production is out of most people's ability for most blockchains anyways. So unless you have $10M on other blockchains, you're just pretending to participate in consensus. Personally, I think consensus decentralization is overrated. Safety, liveness, and anti-censorship are what ultimately matters to normal human beings and crypto users. Development decentralization is also important, but that's another topic, and only Ethereum qualifies for that.

Ah, *Numerous_Wonders81* is doubling down, huh? Let’s break it apart piece by piece. ### 1. **"Single Canonical Implementation Is Common and Beneficial"** - *"Many robust blockchain networks (like Bitcoin Core) rely on one primary, well‑audited node implementation."* Ah, the classic "Bitcoin does it, so it's fine" argument. But Bitcoin’s **ossification** isn't a *feature*, it’s a *problem*. That’s why the blocksize wars were a nightmare—there was no alternative implementation to argue with Core’s decisions. Ethereum **avoided this trap** by ensuring **multiple independent clients**, making it resilient against **protocol stagnation and developer capture**. Algorand, on the other hand? **One client, one point of failure.** If a bug slips through, the entire network is vulnerable. Ethereum’s diversity of implementations **prevents a single exploit from taking down the entire system**. That's not a hypothetical; it’s happened before (like the Geth bug in 2021, where the network survived because other clients picked up the slack). ### 2. **"SDKs Are Not a Substitute for the Node—but They Serve a Different Role"** - *"Bitcoin has many language-specific libraries that simply wrap around Bitcoin Core’s RPC interface."* Yeah… and that’s why **Ethereum isn't Bitcoin**. Ethereum took the lessons Bitcoin refused to learn and evolved. SDKs being separate from the node is **obvious**, but that doesn’t change the fundamental issue: **Algorand lacks client diversity**. The whole "it's open-source, so someone *could* build another client" is theoretical nonsense until someone *actually does it*. Ethereum didn't wait for "maybe someday"—it built in resilience from the start. ### 3. **"Instant Finality" (LOL)** - *"Algorand’s innovative use of cryptographic sortition and a Byzantine Agreement protocol mathematically proves instant finality."* Oh, so they just rewrote how **information propagates** across networks? Must have missed that physics breakthrough. **Reality check**: *Rapid* finality is achievable (Ethereum is close), but **instant** finality? That’s just marketing fluff. The term itself is misleading—"finality" isn't just about a block being proposed; it’s about network-wide agreement. And agreement still takes time because **network propagation exists**. Ethereum’s finality window is fast (especially with Danksharding and PBS coming), and it achieves that **without sacrificing decentralization**. The tradeoff Algorand makes is centralization for speed—because it **has to**. ### 4. **"Room for Future Diversity"** - *"Alternative node implementations can—and likely will—appear over time."* Ah, the "trust me, bro" defense. **If it hasn’t happened yet, it doesn’t count.** Ethereum had multiple independent clients **from the start**. Bitcoin had **alternatives attempted** but rejected them. Algorand? Still waiting for that mythical second client. --- ### **Verdict** This is a classic case of trying to defend **structural centralization** as a "benefit." Every centralized blockchain makes the same arguments: *"our design makes things more efficient!"* Yeah, because it **sacrifices decentralization**. If you prioritize throughput over neutrality, **you're not a decentralized blockchain**—you’re just a fancy distributed database. Ethereum remains **the only functional, credibly neutral blockchain** with client diversity, resilience, and **actual** decentralization. Algorand? Still waiting to prove it’s more than just another narrative play. I'll change my mind the moment **multiple independent Algorand clients exist in the wild**. Until then, it's just a well-branded VC chain.

Numerous_Wonders81

While it’s true that Algorand’s open-source ecosystem includes many SDKs for various languages, it’s important to distinguish between SDKs—which are tools for interacting with the network—and the core node software that runs the consensus protocol. Here’s why the concern about “only one client implementation” misses the mark: Single Canonical Implementation Is Common and Beneficial: Many robust blockchain networks (like Bitcoin Core) rely on one primary, well‑audited node implementation. Having a single canonical client for consensus can actually reduce the risk of divergence or “forks” that can occur when multiple independent implementations interpret the protocol differently. Algorand’s “algod” node is open source, rigorously tested, and designed to meet high standards of reliability and security. SDKs Are Not a Substitute for the Node—but They Serve a Different Role: The multiple SDKs available in languages like Python, JavaScript, and Go aren’t intended to be alternative consensus clients. Instead, they serve as developer libraries to interact with the official node (via its API). This is analogous to how, for example, Bitcoin has many language-specific libraries that simply wrap around Bitcoin Core’s RPC interface. The fact that these SDKs ultimately point to the official installation doesn’t diminish the robustness of the underlying consensus protocol. Algorand’s Protocol Is Designed for Rapid Finality: The claim that “information takes time to spread and form consensus” overlooks Algorand’s innovative use of cryptographic sortition and a Byzantine Agreement protocol. These mechanisms are mathematically proven to achieve consensus rapidly and with instant finality once a block is approved. Multiple academic papers and independent audits have validated these properties. Room for Future Diversity: The ecosystem is still evolving. Algorand’s open-source nature means that alternative node implementations can—and likely will—appear over time. In the meantime, the single, well‑audited implementation provides stability and ensures that all network participants are working from the same codebase, which is crucial for security and consistency. Sources to Consider: Algorand White Paper: It thoroughly explains the consensus mechanism and demonstrates mathematically how instant finality is achieved. Official GitHub Repository: While the SDKs primarily provide interfaces for various languages, you’ll also find the official “algod” node implementation, which is actively maintained and audited. Comparative Analyses: Articles from reputable sources like CoinDesk or academic publications have detailed how Algorand’s approach differs from multi-implementation systems and why it’s effective. In summary, the presence of multiple SDKs confirms a vibrant developer ecosystem and does not equate to having multiple independent consensus clients. Having one well‑audited, canonical client for the core protocol is both common and advantageous—it helps ensure that consensus is reached reliably without the risks associated with divergent implementations.
