The mailing mention NTRU would make node perform extra validation, yet NTRU implementation show it's far faster than ECC-NIST (closest one to cryptography which Bitcoin use). Can someone explain why? Source: https://tbuktu.github.io/ntru/

Blocks can be lower than the "maximum" block size (currently 4 Weight Units).
To be more precise, maximum block size was 1MB before SegWit activation (August 2017) and now it's 4 million weight units (some people also refer it as 4 kWu). Most of the first thousands blocks are empty and the rest (until Bitcoin became famous) only have a small number of transactions included, so their size are only a few kB.
Or rather few hundred bytes.

Saya tidak familiar dengan file MANIFEST-... dan saya hampir tidak pernah menemukan diskusi yang membahas file tersebut, sehingga saya tidak bisa memberikan solusi. Walaupun, pas awal-awal sempat ada error leveldb: Compaction error: IO error: /mnt/ext/bitcoin/chainstate/811167.ldb: Bad message Dan juga yang terakhir: 2022-04-10T15:48:11Z ERROR: ReadBlockFromDisk: Deserialize or I/O error - ReadCompactSize(): size too large: iostream error at FlatFilePos(nFile=40, nPos=18863821) 2022-04-10T15:48:11Z *** Failed to read block 2022-04-10T15:48:11Z Error: A fatal internal error occurred, see debug.log for details 2022-04-10T15:48:11Z Failed to connect best block (Failed to read block) 2022-04-10T15:48:11Z loadblk thread exit
HDD yang digunakan jelas bermasalah, coba 1. Cek status S.M.A.R.T dan lakukan testing pada HDD tersebut. https://wiki.archlinux.org/title/S.M.A.R.T.2. Menggunakan kabel dan port yang berbeda.

I agree, although IMO a week for sync is long enough to discourage few people even if they don't need it up quickly.
Why that hurry, though? I am confident if there was a strong demand for faster IBD, we would have many more people working on and campaigning for stuff like checkpoints on the blockchain. Some people simply not patient. Idea for faster IBD such as UTXO commitment already suggested several times, but receive little support/interest. That makes sense, but there are few use cases where you need to use remote/centralized server. For example, small business or non-profit organization who run BTCPayServer.
Correct, yes. In that case, the node may be required to run the payment server on top of it, but those nodes shouldn't be considered part of the 'secure, reliable backbone' of the network, in my opinion. It's not like we can tell a node is part of the "secure, reliable backbone" unless they use popular VPS which it's IP range is known without VPN or Tor. Why do you think I should run a Bitcoin core wallet while there are many wallet/exchanges like Binance and Coinbase? I know it's essential if you hold a bunch of Bitcoin. But, I have such a tiny amount of Bitcoin (below $1K). I think I can hold them on Binance and stake it to accumulate more satoshi.
TLDR, better privacy and you actually have control over your Bitcoin. Although you can use SPV non-custodial (with Tor/VPN) such as Electrum to receive similar benefit. I have a Ryzen 3 3200G CPU+ 16GB Ram + 2TB HDD PC. Can I install the full node in this setup?
Yes.

Drive prices are falling insanely fast even with all the chip shortages and shipping issues all over the world. I just got an 18TB drive (on sale) for $300 1 & 2 TB are under $50. While I know that may be a lot of money for some people in parts of the world those are new prices. I have seen 1TB used for under $5 in places.
I agree, although it's different case if you need to host full node on remote server. Time to download is probably not as big a concern then people who have bandwidth amount limited plans.
Aside from bandwidth, you also need to consider CPU speed, RAM capacity and HDD speed. HDD speed can be partially solved by moving chainstate directory to SSD or allocate very big RAM to Bitcoin Core (IIRC at least 8GB).

Coinbase verified - 300$ (without documents) - 950$ with documents US
why garbage if im following the rules man >? you cant just post a negative comment just like that !!! OMG what's wrong with you people !!! im selling these accounts for marketing !!! marketing buying all kids of social media to promote their products !!! if u dont know these things don't even comment and judge me !!!
its not my problem to have so many scammers here !!! but to -4 trust just like that ? even you wouldn't accept this
Talking about rules, have you explained why verified Coinbase you sold isn't hacked? It's not allowed to sell hacked account and verified/KYCed account assumed to be hacked unless you give explanation. You are only allowed to sell accounts/invites that you legally obtained yourself or through legitimate trades. If you did anything illegal in order to obtain an item, then you can't trade it on bitcointalk.org. Anyone found breaking this rule will be banned.
Accounts on sites that require KYC such as bank accounts, PayPal, etc. are assumed to be hacked unless you explain why they're not hacked.

I checked the website and found out the reason. RSK itself is Bitcoin sidechain network with smart contract capability[1]. Additionally they use merged mining which tied to Bitcoin network[2], so miner who mine Bitcoin also could mine RSK altogether. Carnaval itself use RSK which support token and NFT generation[3]. Carnaval, powered by RSK, develops the first marketplace on top of the most secure and most adopted blockchain: Bitcoin. Lower fees, awesome network effect and an incredible community are just a few of the advantages.

But currently ElectrumX is most popular version.
Imho ElectrumX is the most popular for "public" use. For local use it may be a bit of overkill. But actually that's only a feeling, I don't know that for sure. I can understand why you think it's overkill for personal usage. But i'm not fan of lighter alternative Electrum Personal Server[1] since you need to enter each master public key (xpub, ypub or zpub) or address manually. electrs[2] might be best option for personal usage, but i never tried it. I may also give it a go under WSL when I get a bit more free time. Not necessarily because my current setup would be bad, it's just that I like a bit more the interface of mempool.space than of the block explorer I use now. So I'll bookmark myself these links If you plan to try Docker, AFAIK you could just install Docker for Windows so you don't need to setup WSL.

Jangan dipaksakan mas jika sekiranya kapasitas HDD internalnya memang nge-pas. Oh ya HDD eksternal-nya itu yang dicolok langsung via USB saja atau menggunakan semacam enclosure docking yang ada tambahan lagi power untuk listriknya? Saya pribadi lebih prefer menggunakan yang ada tambahan power lagi untuk yang eksternal.
HD 2,5 bekas copotan laptop lama yang rusak Mobo-nya. jadi saya beliin Casing eskternalnya aja untuk supaya bisa konek ke laptop. Saya pernah juga nyari casing yang ada power suply ke listrik/ enclosure docking, tapi katanya gak cocok karena lebih prefer ke HD 3,5 atau HD yang biasa di PC. Sebagai alternatif, bisa menggunakan kabel dengan ekstra head sebagai suplai energi tambahan.

What exactly do you mean by merge? If you mean merge multiple cryptocurrency network into 1 big network, it's impossible since each network have different protocol.

would you prefer i store a 60KB picture of my daughter's cat using 700 transactions or 1 transaction? What we prefer is for bitcoin to be used as it was meant to, meaning as a payment system not a distributed database where arbitrary data is being stored. Exactly, there are different protocol (such as IPFS and BitTorrent) which is more suitable for distributed data sharing. Besides, it's more practical to use OP_RETURN to share hash of the IPFS/BitTorrent instead.

OP, do you mind sharing why exactly you need create to create a transaction from PK using library/3rd party API? It sounds like XY problem and we could suggest better solution if you tell what's your goal. If you value security, I'd suggest downloading a wallet like electrum (from electrum.org). The initial sync of a new wallet can take a few minutes and a few MB but it's a lot faster than bitcoin core.
Electrum also support CLI[1] if OP use-case involve server which doesn't have GUI. The documentation doesn't mention all command though, so you need to run electrum help or check the source code[2] [1] https://electrum.readthedocs.io/en/latest/cmdline.html[2] https://github.com/spesmilo/electrum/blob/master/electrum/commands.py

- This wallet uses public APIs like Blockchain and Blockchair for UTXO data and they probably track your IP! Use a VPN.
I checked the live demo and saw there's network access to wss://api-pub.bitfinex.com/ws/2, did you forget to mention it?

It's definitely possible, several extension (such as MetaMask) use those feature. The real question is, are there any contributor willing to add and maintain such feature?
The local storage is probably not a problem. Just the notes will not be synced between multiple devices. Synchronization problem could be solved with cloud storage API. But it means more difficult implementation/maintenance (developer side) and longer initial setup (user side). If OP really wants to save info into browser, maybe a Firefox extension like Very Simple Notepad could help, although I'd prefer a proper local text file.
Might as well install proper note taking application if OP bother install such extension since usually it has more feature.

Here's alternative illustration with horizontal tree diagram. If the node doesn't have child (also called leaf node), it means unspent and vice versa. Rustie TX1 Derrick TX2 Gloria UTXO A -------> UTXO B -------> UTXO D 100 BTC | 50 BTC | 25 BTC | | | Rustie | Rustie |---> UTXO C |---> UTXO E 50 BTC | 15 BTC | | Derrick |---> UTXO F 10 BTC

Anyone got any thoughts on them?
Sound shady or confusing. Looking at mining page[1], it's as if they perform mining and share small profit depending on your trading volume. I would say it's not worth since you need to trade about 150.000 USDT to get about 0.88 USDT daily which is very small compared with their fee[2]. Or maybe someone knows a better service?
Buy and configure your own mining hardware. [1] https://stormgain.com/bonuses/bitcoin-mining[2] https://stormgain.com/fees-and-limits

no, they are all valid transactions to users who just haven't been born yet But you could just use OP_RETURN! Better: you could use OP_RETURN inside TapScript and just commit to the blockchain, instead of burning coins! There is no reason to burn anything, there is also no reason to bloat the chain. Another thing is that one commitment for the whole network would be cheaper than pushing every commitment for every user. using OP_RETURN to store data in blockchains actually creates far more bloat then the method we are describing here. the maximum amount of OP_RETURN data currently supported by the network per transaction is 80 bytes.... i think.. it has been awhile since i checked. 80 bytes limitation is only enforced by Bitcoin node though. If you're pool owner or can convince pool miner to add your transaction, OP_RETURN would create less bloat.
