The hardcoding, which is similar to the BIP90 hardcoding made a couple of years ago, simplifies Bitcoin Core’s consensus code. This week’s newsletter notes a change to Bitcoin Core’s consensus logic and announces a new feature on the Optech website for tracking technology adoption between different wallets and services. ● New Optech Compatibility Matrix: a new feature on the Optech website shows what wallets and services support certain recommended features, currently opt-in Replace-by-Fee (RBF) and segwit (with more comparisons planned for the future). You can publish your private view keys on your website for your transactions to visible to whoever has them. 2924 abstracts C-Lightning’s database handling code and SQL queries so that it can be adapted to handle other backends besides the default sqlite3. For example, nodes are now penalized in the routing preference database if they produce an error message that they shouldn’t be generating given their particular role in a transaction (e.g. intermediate node or final node). 1937 stores the most recent channel reestablishment message in the node’s database so that it can be resent even after a channel has been closed.

Every 2,016 blocks (approximately 14 days given roughly 10 minutes per block), nodes deterministically adjust the difficulty target based on the recent rate of block generation, with the aim of keeping the average time between new blocks at ten minutes. First I have a cable modem now and can upload stuff at a much faster rate (take that 28.8k modem). When you buy bitcoin directly from PayPal, it earns money from the crypto spread, or the difference between Bitcoin’s market price and its exchange rate with the U.S. The global cryptocurrency market cap dropped 3.75%, and Polygon experienced a decrease of over 4%, while other top cryptocurrencies also showed reductions. The total supply of bitcoin has a cap of 21 million coins, 바이낸스 가입 혜택 meaning once the number of coins in circulation reaches 21 million, the protocol will stop minting new coins. Andrew Chow lists several considerations regarding public keys and quantum resistance, including: the need to reveal the public key during spending, the large number of bitcoins in outputs with known public keys, and numerous ways which public keys are exposed outside of just transacting due to not currently being treated as secrets.

Using a single policy reduces the number of routes the node needs to evaluate when making a payment. Platforms and services, like travel booking site Travala, payments gateways like Moonpay and Banxa, payment APIs like Wyre and multi-currency payment services like ivendPay and Paylot are now supporting BUSD too. In 2013, a Utah manufacturer of these tokens was ordered by the Financial Crimes Enforcement Network (FinCEN) to register as a money services business before producing any more funded bitcoin tokens. Watchtowers are services that broadcast penalty transactions on behalf of LN nodes that may be offline, recovering any funds that would otherwise have been lost due to an old channel state being confirmed onchain. LN-penalty prevents counterparty theft by giving nodes the ability to financially penalize a counterparty that attempts to publish an old channel state onchain. Naumenko’s email requests feedback on which method would be preferred by implementers of both full nodes and lightweight clients.

This week’s newsletter requests testing of the latest release candidates for Bitcoin Core and LND, describes how helping people accept payments to bech32 addresses can lower fees, and lists notable code changes in popular Bitcoin projects. It’s hard to imagine a simpler data format, and a lot of people depend on it, so you’d think they’d nail down a specification. If any member companies who think they’ll be able to attend have topics they’re interested in discussing, please email Optech. The person who initiates channel opening is responsible for paying this amount (as they are responsible for paying all fees in the current protocol), so they would probably like to keep it low-but the amount must be greater than most node’s minimum output amount (“dust limit”). ● CPFP carve-out: in order to spend bitcoins, the transaction where you received those bitcoins must be added to the block chain somewhere before your spending transaction. To help solve this problem, Matt Corallo has suggested a change to the CPFP policy to carve-out (reserve) some space for a small transaction that only has one ancestor in the mempool (all of its other ancestors must already be in the block chain).
