18808 causes Bitcoin Core to ignore any P2P protocol getdata requests that specify an unknown type of data. This is included in the second release candidate for Bitcoin Core 0.20 linked in the preceding section. ● LND 0.10.1-beta.rc1 is the first release candidate for the next maintenance release of LND. While bitcoin (BTC), litecoin (LTC), dogecoin (DOGE), and others are the most known cryptocurrencies, they are merely the first generation of blockchains with the sole purpose of producing one product – digital money. This makes it safe to switch to a new HD seed with the sethdseed (set HD seed) RPC even while the node is performing an initial block chain download, such as when restoring a wallet backup on a newly-started node-the updated code ensures the wallet will see any payments to addresses previously derived from the old HD seed. For now, the only difference between the new and old binaries is their name.
10102 is merged, the new binaries will split the functions of node, wallet, and GUI into separate executables that communicate with each other when necessary. Additionally the keys necessary to spend the coins won’t be contained in the user’s BIP32 HD wallet, so additional backups may be required. ● Two-transaction cross chain atomic swap or same-chain coinswap: Ruben Somsen posted to the Bitcoin-Dev mailing list and created a video describing a procedure for a trustless exchange of coins using only two transactions, named Succinct Atomic Swaps (SAS). Somsen’s SAS protocol leaves each party holding coins that they can spend at any time-but which they may need to spend on short notice if their counterparty attempts theft (similar to how LN channels need to be monitored). A list of curated resources relevant to Lightning Network can be found here. The larger effort to remove all private key handling can be tracked here.
You (or a watchtower acting on your behalf) can then activate an emergency protocol to recover most of the secured funds. There’s a classic scam in the “crypto” space: advertize Bitcoin to get people in, then sell suckers something else entirely. ● Implementing statechains without schnorr or eltoo: statechains are a proposed offchain system for allowing a user (such as Alice) to delegate the ability to spend a UTXO to another user (Bob), who can then further delegate the spending authority to a third user (Carol), etc. The offchain delegation operations are all performed with the cooperation of a trusted third party who can only steal funds if they collude with a delegated signer (such as previous delegates Alice or Bob). Binance fees are some of the lowest in the industry, whereas Coinbase does not disclose its fees online. You can even see entities like Coinbase listed on stock exchanges. It can use BEP-20 tokens within the network to function on various DeFi protocols like DApps, DEX and wallet. Especially in a crypto exchange platform like Binance, withdrawal fees are one of the major contributors to the revenue it generates.
Also included are our regular sections describing changes to services and client software, new releases and release candidates, and notable changes to popular Bitcoin infrastructure software. This week’s newsletter links to a prototype for creating vaults using pre-signed transactions and includes our regular sections about notable changes to services, client software, and popular Bitcoin infrastructure projects. Advantages of the protocol are that it requires less block space than existing protocols, it saves on transaction fees (both by using less block space and potentially by requiring less urgency for its settlement transactions), it only requires consensus-enforced timelocks on one of the chains in a cross-chain swap, and it doesn’t depend on any new security assumptions or Bitcoin consensus changes. No, the offers you see on the P2P market are not offered by Binance. 18861 prevents the node from replying to a P2P protocol getdata request for a transaction that it hasn’t yet announced to the requesting peer. ● Blockstream Satellite 2.0 supports initial block download: https://progress-model.com/%EB%B0%94%EC%9D%B4%EB%B9%84%ED%8A%B8%20BTC%EC%99%80%20%EC%9E%90%EC%82%B0%EC%9D%84%20%EB%8A%98%EB%A6%AC%EB%8A%94%20%EB%B0%A9%EB%B2%95 Blockstream outlines version 2.0 upgrades to their satellite service which include expanded Asia-Pacific coverage, additional bandwidth, and an updated protocol that enables a full node to complete an initial sync using only the satellite feed.
