RAM

Ok-Employ-1029

Yes, I was going to say the same. I don't know what size Eth's full chain history is, but the 2tb is for validating current blocks, the technicalities of which I don't understand. So it appears that Solana needs 256GB RAM (or perhaps more now?) to hold the entire global state in RAM, is that correct? The thing which I don't understand is the extent to which historic data is relevant and important for security. For instance, a bitcoin node will replay and verify every transaction. If Solana can really reach something like a millions tps, the chain will grow so fast... what practical consequences will follow?

CrazyAppel

It's not centralized and the whole reason Solana is scam-ridden is because it's not centralized lmao. The argument for it being centralized is that it's expensive to run a validator node (you need 256gigs of RAM and at least a Cooperlake Xeon CPU), but a lot of people understand things backwards. Solana uses PoH, mainly built by Anatoly, his whole idea was to have the lowest block times and the fastest transaction speeds, resulting in high node costs. By abusing these metrics, you can build stuff like bundlers that can buy your own coin from a bunch of different wallets at the same time when your coin is created. It tricks newbies into thinking your coin is active, you can easily sell all supply after with a single press of a button. Creating a rugpull coin costs you like 100 bucks max and a few hours of your time, THAT is why this chain is so scam ridden. The product is actually good though, PoH is a handcrafted and masterfully coded piece of artwork by mostly one person. All good things end up being abused hardcore

Only way they'd do this is if the device still had the seed stored in RAM for some reason or if the seedphrase itself was stored in a file/password manager they managed to gain access to.

Aussiehash

Well if you are happy to pay for the "best" take a look at Start9 https://store.start9.com/ On the other hand I am perfectly happy with my Pi4b 8GB (or you could use Pi5 with 8GB RAM) and USB 3.2 SSD/NVME. 1TB is barely enough now for a full node with additional Electrs/Fulcrum database, so I would suggest either 1.5TB or 2TB SSD/NVME storage

Trilzerobyte

Do you just want to run Bitcoin Core, or also Lightning, Electrum server, a web UI, block explorer?  If just Bitcoin Core then you may get away with 2GB RAM. But what CPU do you have? Do you want to verify all the blocks from the genesis? Many NASes are low powered ARM servers. If it's equivalent to a RPi 3, it'll take nearly a month to sync the blockchain. If you don't need to verify old blocks, then you can copy the block data from another machine you trust. Once caught up to latest block, you only need to verify one block per 10 minutes on average so it's easier to stay caught up than to initially sync.

There are two sides to "safety" when it comes to storing Bitcoin seeds/keys: 1. The likelihood that someone you don't want to have access to your seed/key will gain access to your seed/key 2. The likelihood that someone you want to have access to your seed/key--e.g. YOU--will lose access to your seed/key Storing your seed/key in a Minecraft world MIGHT have low likelihood that someone else, including malware scanning your computer or your network, will discover it. But you'd be making a lot of assumptions about how the world is physically stored on disk, how it's stored in RAM, etc. Don't equate "I don't know how objects in Minecraft worlds are stored / most people don't know how they're stored" with "objects in Minecraft worlds are undiscoverable outside the world". Storing your seed/key in a Minecraft world has a moderate to high likelihood that YOU will lose access to it. Minecraft software changes frequently, and there's no guarantee that, ten years from now, you'll be able to find software that can render the world you made in 2023 exactly as you left it.

RAM is definitely one to keep an eye on. With the EOS spring fork dropping soon, the demand for RAM is about to pop off, and a 100x surge could be just around the corner as more projects start building on EOS.

RWA still a good category with lot of money flowing in there. ONDO, RAM and OM are a good bet. A lot of projects like exSat are utilizing RAM for storage which eventually creates demand.

One variable I found important in downloading the full blockchain was RAM. Not CPU. Not bandwidth. If you don't have enough RAM you'll be swapping to disk so much it will seem like the bandwidth is the bottleneck. Check what your machine is doing, mine with 4Gb initially was working the HDD _hard_.

jpowsecretstack

I'm glad you mention that. Tails OS runs entirely in the computer's RAM and does not rely on the hard drive, meaning it operates independently of the underlying hardware. This means that any tampering or malware present on the computer, such as on the hard drive or firmware, is bypassed when using Tails! Since no part of the OS interacts with the potentially compromised hardware, it's considered ultra secure for tasks like manipulating Bitcoin seeds, protecting against pre-existing hardware-level threats. Electrum comes pre-installed with Tails so that you do not need to connect to the internet when creating your seed. It's basically more secure than an offline signing device or seed generator like Ledger, Trezor, etc as you remove the hardware tampering risk. I hope that helps.

Schmiegefp

In the RWA narrative, I'm replacing RIO with RAM, a RWA on EOS.

TaGoItFr

Yeah, because seed signer doent need a secure element. Seedsigner doent save data to the device. Its operations work on RAM memory. So you just need to generate a xpub and store just this save. The seedsigner dont save your seedpgrase so its the savest method...

Indeed, the best way is to download the spreadsheet and use it in an always-offline computer. And there is no need to save the file with your seeds typed, keep it just in RAM memory.

This is a version of JIT memory management. RAM is volatile and more expensive than near line or cold storage, so if you can process data from cold storage without needing to load it into RAM, that means you have made a major leap in JIT processing

Tasty_Action5073

Swapfiles…damn this is so old I hope I remember correctly what I’m about to say… is what we used to do as virtual RAM. Your computer will dedicate an area that is quicker to access than fetching files from the hard drive to use as RAM. So it’s just extended RAM really. Now how you found it and why you think it has Bitcoin I don’t know. But I reaaaally doubt your Bitcoin wallet was stored in RAM, and in this situation in the Swapfile.

no idea what that is, old bitcoin files are usually wallet.dat a swap file is usually temporary storage between RAM and your disk drive

Is there anything else I would need to purchase (I already have a 2 TB SSD from my node)? Can Start9 run wirelessly or do I need to connect directly via ethernet?

Was thinking about running a full node at my house and buying a "Intel NUC NUC7i5DNK i5-7300U @ 2.6GHz 8GB RAM 250GB SSD Dual HDMI WiFi Win11 Pro". I know the processor is not quite up to specs per the bacloud.com help pages. Does running it on Linux vs Windows allow you to use a processor that is not as powerful? Or is the performance negligible? Asking because I'm more familiar and comfortable in windows but can navigate around in linux with enough time.

Is this because they follow point 7 in Bitcoin's whitepaper while Bitcoin does not? >Reclaiming Disk Space >Once the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. To facilitate this without breaking the block's hash, transactions are hashed in a Merkle Tree [7][2][5], with only the root included in the block's hash. Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do not need to be stored. >A block header with no transactions would be about 80 bytes. If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, **storage should not be a problem** even if the block headers must be kept in memory

It's ok to sell ADA and XRP. SOL is good and might also have a run if you can be patience. Better still, it's best to look into other coins that are making waves. EOS and RAM among others have been trending as they revamp their tokenomics. Burning 80% of EOS FDV and also staking is live.

It's best to DCA into BTC if you have some good capitals but not with 100 bucks. I will recommend you put that in other solid alts like RAM. You dont have to spread it yet. Just buy one single coin with conviction. RAM has good utility and high demand for storage. You can always do your research before tou invest in any token.

castorfromtheva

Get a used lenovo tiny or Dell optiplex with at least a Gen. 6 CPU and a 2 Tbyte SSD. Along with at least 4 gigs of RAM or at least 8 GByte if you plan to also run a lightning node and others services like an own mempool explorer or Electrum server on top. All in all such a machine will be 150 to 200 bucks and will cost you around 2 to 3 bucks per months in energy.

castorfromtheva

These days the initial blockchain dowload takes around 2 to 4 days given you are using a normal x86 CPU, not a Raspi one, have a least 4, better u 8 gigs of RAM and most important uses a SSD you're syncing to. Patience is one of the most important virtues bitcoin teaches anyways.

RWA are worth investing into. I'm accumulating RAM on EOS. Just buy some EOS and move them to RAM but both tokens will have a good run looking at the 80% supply burn in the new tokenomics.

IndubitablePrognosis

I lived through the block wars, but haven't read the recent books, no. It doesn't interest me very much because I just don't see any way for Layer 1s to be payment systems. Certainly not Bitcoin or Bitcoin Cash. 10 minute blocks are not "payments". DAGs and Solana can get fast but they have centralization issues (512GB RAM and megabit+ to run a node?). Lightning payments increase block usage because they are in addition to standard transactions (non-payments). The network effects of an increased user base result in more demand, which means more lightning nodes and more transactions (and more expensive ones, if node operators want to prioritize their channel opens). Additionally, if users are "onboarded" via Lightning, they later "graduate" to using mainchain transactions-- They DCA via Lightning, then consolidate to an on-chain HODL wallet. If you look at the mempool, there is no shortage of transactions to build blocks and make a profit. There are also Runes and such-- Look at the first couple blocks after the last halving. I don't think any miners were complaining about the block subsidy being reduced, given that the fees to mint Runes were insane. I don't think it makes much sense to talk about block subsidy having to do with profitability of miners-- the block rewards have been known since before the network started up; any potential miners knew there would be halvings, and when they would occur.

izdigohkz

Great plans. I'm actually looking into crypto with real-use-case. RWA mostly fill this list and one of them is RAM in the EOS ecosystem. The ecosystem is growing and projects are developing on it, they all require RAM which will continue to increase the demand for RAM. My best bet is to but EOS and move it to RAM. RAM and EOS are considerable cheap at the moment.

MPH2025

Uh….because that’s thee ideal situation. Keep a QR code for scanning in your private key, then when the device is powered down, RAM clears the key.

MinimalGravitas

The limits on blockchain throughput vs decentralization are really simple to understand if you stop to think about it. The nodes that run the network have to verify all of the transactions that occur within a block, before the next block arrives. To do this requires a certain amount of hardware and a certain speed of internet connection. The more transactions processed per block, and the faster these blocks arrive, then the higher these requirements are. Chains like Bitcoin and Ethereum (and Monero, Cardano, etc) prioritize the ability of users to operate nodes. They can connect via regular domestic broadband and run on cheap hardware. If you as a user cannot run a node then you can't directly post transactions or even check your balance, you are forced to rely on 3rd parties, which kinda defeats the entire purpose of crypto in the first place. Faster, cheaper smart contract chains are easy to create, but there is no way to get around the fact that for a node to work it has to receive, process and upload all that data... which is why for example to run a Solana node you need a machine with 256GB of RAM and more importantly an internet connection with a speed of at least 1GB/s, up and down. In summary, there are not any chains *"that have solved all of these issues"*, they have just abandoned the one factor that makes crypto better than traditional finance and managed to trick a bunch of naive newbies into thinking that sacrifice is somehow a good thing...

Hitchie_Rawtin

Independent data centers versus AWS, Azure, Google Cloud, they're decentralising away from the kings of industry. Much much lower egress (data output) cost, one vertical tech stack versus you needing to sort out separate database, security, server accounts which introduce vectors of attack - exploits tend to exploit vulnerabilities in between the sellotaped-together current Web2 stack. Well, that and people, people making mistakes are usually the main culprit in a hack. They're going to be allowing servers outside of the strict spec they have at the moment eventually, but it'll still be very high spec and you'll need a 1Gbit connection minimum, I think the machines at the moment cost about $22k and require 30TB of NVMe storage 512GB RAM and an AMD Epyc CPU. I'd expect the next generation of requirements to be higher spec and probably around the same cost. Whether they allow you to become a node or not also depends on use of the network - there's no point paying tons of node rewards to an ever growing flood of nodes that aren't anywhere near max capacity. Current usage suggests it could be a year or two before they open up to onboard the people who've already signed onto the waitlist to become a node. There was talk about creating a sibling network called "Badlands" where the system requirements would be more of an anything-goes and people could choose poor performance for the sake of greater decentralisation, but that has been shelves at least for the time being. I personally think there's no point in doing it because it sounds like exactly what Maidsafe/Autonomi is aiming for, they can let them do the Badlands thing and incorporate and communicate with that chain via a canister in the future. Plus it's a bit of a waste of Dfinity's R&D time when they should focus purely on bolstering the IC's tech stack.

cpt_charisma

Download time isn't the only problem, though. OP will probably spend days or weeks waiting for his computer to verify all the transactions. The fastest PCs can do it in 2ish days. After that, the real physical limit becomes the amount of RAM it takes to store the unspent transaction set (UTXOs.) If you don't have enough RAM for that, you risk falling behind the network and not being able to catch up - especially if you're using spinning disks.

A Raspberry Pi5 with 8GB RAM and a USB3.1 external SSD/NVME works well. I would recommend a fan enclosure for the Pi5 and the official Pi5 power supply. It is currently possible to fully sync the Bitcoin blockchain + Electrs/Fulcrum, but soon you will need more than 1TB storage.

Amber_Sam

Bitcoin blockchain size is at about 600GB, going 20X, we're talking about downloading over 10TB of data to set a new node up. The node will also need more CPU power as well as RAM. Now think of the plebs in third world countries.

detifiai

Running a Bitcoin node on your everyday PC is totally doable and it has some cool benefits like helping the network and enhancing your privacy. But there are a few things to watch out for: 1. **Resource Usage**: It’s pretty heavy on your system. The Bitcoin blockchain is huge (over 400 GB) and it's only getting bigger. This can slow down other tasks you want to do on your PC as it eats up RAM and bandwidth. 2. **Security Risks**: Having your node online increases your exposure to potential attacks. You'll want to make sure your firewall is tightly configured to avoid vulnerabilities. 3. **Privacy Concerns**: If you're not careful, running a node could leak sensitive info, like your IP address being linked to Bitcoin transactions. 4. **Uptime and Maintenance**: Your node needs to be online as much as possible to really be effective, which can be a hassle if you use your PC for other daily tasks. 5. **Electricity Costs**: Expect your energy bill to go up since your PC will need to run more or less constantly. If you decide to go for it, using a VPN or Tor can help protect your IP address, and setting up your node in a virtual machine could isolate it from your main system, adding an extra layer of security. Hope this helps!

If you look up the DIY guides of myNodeBTC, Umbrel and Raspiblitz, you need a Pi4b (8GB RAM) or Pi5 + Official Pi power adapter + USB 3.1/3.2 SSD (Samsung work well) + enclosure (for the Pi5 you want an enclosure with a fan) + MicroSD (16-32GB)

I can't imagine the Yacht captain being happy with you draining the batteries and internet 24/7. A Pi4B or Pi5 would use less power than (I assume the Intel/amd/x86 server with 16GB RAM)

You seem confused about the difference between wallet and address. A "wallet" is actually a whole bunch of addresses controlled by the same application. Modern Hierarchical Deterministic wallets (most software use these) can generate billions of addresses from a seed (represented by the 12 or 24 words you write down to back up the whole wallet). If you are sending from one address to another in the same wallet (unnecessary, and costs fees), it will look like the coins disappear for a while, then reappear after they are confirmed, especially if your wallet isn't seeing the transaction while it's pending confirmation. Another thing is understanding UTXOs (Unspent Transaction Outputs). A wallet shows you a "balance" of all your addresses, or a total in each address, but none of these are how it works on the blockchain. Each actual payment creates an output, which can be spent separately, and MUST be spent entirely or not at all. So if you had one output and sent part of that amount, the wallet may have needed to split it by sending some amount to your destination, and the remainder would be sent back to you as "change" - usually to a different address for privacy reasons - but would always be to an address in the same wallet. While the transaction is unconfirmed, the wallet MAY show the change as gone, and then back again when confirmed. This is normal. Again as someone said, it depends which wallet software. Also, the mempool is pretty congested so if you send with too low of a fee, your transaction won't be confirmed for a long time, or maybe ever. If its really low, it may not even appear in any other node's mempool (because they have a limited RAM for unconfirmed transactions, they discard the ones with the lowest fee first). If you are receiving significant amounts unexpectedly it's possible you and someone else generated a wallet from the same seed, which is usually a bug or a mistake, not likely to happen if your software correctly generated the seed at random. Make sure you didn't form the wallet by entering seed words from a video or tutorial?

Maybe it was 4 petahashes, no, it was RAM, not an nvidia stack for monero

Good Questions, I run mine using a laptop which actually has less RAM and a worse processor than this RPI. I actually have an RPI as well, but I use it for unrelated things. This just goes to your point that any laptop or RPI would work. However, for the hard drive requirements, they are more substantial than a few gigs of space. The current blockchain size is around 570 GB, so having 2TB is plenty futureproof.

I am actually doing the same today! I found one of my old drives with a few wallet.dat's, bitsquare.wallet, and a couple multibit.wallet's. so far only about 520 BTC but not bad for adding to my collection of other wallets i have stored from the old days. Crazy to think i found the BTC mining tut in 09 on a hacking forum and took a gamble back then. I think my old laptop had backtrack and like 4GB RAM.

I've heard great things about Umbrel, super user-friendly and easy to set up. That Pi5 with 8GB RAM and 2TB SSD will handle it like a breeze. Let us know how it goes!

Bad thing is if the brain is without oxygen it is like the RAM is wiped forever. If he will be unfreezed in the future he will have no memory or personality.

>A block header with no transactions would be about 80 bytes. If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory.

I did a pi4 -4 GB with 2 tb SSD and its going great. I am not using lightning channels to the 4GB RAM is totally fine.

I got a pi 5 w/ 8GB RAM and a 2TB SSD running umbrel recently. Fun to put together as a father-son project and it works like a champ.

Umbrel is good. It's easy to run and runs really stable! I compared it to a lot of other implementations and so far Umbrel works best compared to others! I recommend running it on a real x86 pc rather than on pi. Much more power while still being very energy efficient! Look for things like (used!) Lenovo Tiny mini pc with at least a generate 6 CPU (i3 6100t or above) and 8 gigs of RAM. On top get a 2Tbyte SSD and you're good to go for the next 5 years. Won't cost you more than approx. 200 bucks plus around 1 to 3 bucks per month for energy (in case you run it 24/7/365 as usually recommended, because quick availability).

If you don't have any of the addresses / XPUB then you can download a list of every on-chain address with a balance (could be limited from 2017-2018) and either load them into a hashset in memory or a bloom filter (if you don't have enough RAM).
