Bitcoin Optech Newsletter #24

Description

● RBF usability study published: with only about 6% of the transactions confirmed in 2018 signaling support for BIP125 opt-in Replace-by-Fee (RBF), Optech contributor Mike Schmidt undertook an examination of almost two dozen popular Bitcoin wallets, block explorers, and other services to see how they handled either sending or receiving RBF transactions (including fee bumps). This week’s newsletter announces the newest version of LND, briefly describes a tool for generating bitcoin ownership proofs, and links to an Optech study about the usability of Replace-by-Fee. This week’s newsletter describes the availability of a libsecp256k1 fork implementing BIP-Schnorr compatible signatures, lists popular questions and answers for February from the Bitcoin Stack Exchange, and describes notable merges in popular Bitcoin infrastructure projects. Also includes a description of adapter signatures, which can be used to enhance the efficiency and privacy of trustless contract protocols. This can often improve the privacy and efficiency of the onchain parts of protocols by removing the need for including special data onchain, such as the current use of hashes and hashlocks in atomic swaps and LN payment commitments. The user can still generate a P2SH-wrapped segwit address by unchecking a box on the Request Payment screen in case they need to receive money from a service that doesn’t yet provide bech32 sending support.
This means more people spending native segwit inputs lowers the fee not just for those spenders but for everyone who creates transactions-including wallets and services that support sending to bech32 addresses. 15711 generates bech32 addresses by default in the GUI. ● Why does BIP44 have internal and external addresses? Pieter Wuille explains that BIP32, upon which BIP44 is based, encourages using separate derivation paths for these keys in case you need to prove to an auditor how much money you’ve received but not how much money you’ve spent (or have left). Services that want to minimize exchange rate risk will need to pass a lower expiry value when using the invoice RPC. 2554 changes the default invoice expiration from one hour to one week. This is the time after which the node will automatically reject attempts to pay the invoice. 2380 requires transactions have at least one confirmation before the wallet will attempt to spend their bitcoins by default. Usually, the public key or bitcoin address is also printed, so that a holder of a paper wallet can check or add funds without exposing the private key to ai
By giving the auditor the extended public key (xpub) for just the external addresses, he can track your received payments but still not receive any direct information about your spending or current balance via the change addresses. Several RPCs related to payments receive a minconf parameter that defaults to 1 but can be set to 0 to continue the old behavior or set to a higher value if desired. This fixes a problem where the wallet would attempt to spend its own unconfirmed change outputs but those payments would sometimes get stuck because the earlier payments weren’t confirming quickly. Keys imported this way will be converted to the current wallet datastructure, 바이낸스 OTP (redirect to untoldjekyll.com – https://untoldjekyll.com/28832/how-to-teach-bitcoin-better-than-anybody-else) but the eventual plan is for Bitcoin Core’s wallet to use descriptors internally. The Binance trading bots also work on grid trading strategy and when properly deployed, these bots will help you earn optimal gains. Different types of trading bots are there for traders, each with different trading strategies, and different algorithms for different types of traders. A plethora of cryptocurrencies, advanced tools, market volatility, and trading strategies may all cause confusion to the new as well as experrs.
Margin trading is widely used in stock, commodity, and Forex trading, as well as the Bitcoin and cryptocurrency markets. As we noted earlier, one of the main attractions for avid cryptocurrency traders is that the platform has one of the largest lists of supported coins. If you copy trades from multiple traders your chances of losing may increase. Users can prepare spot trades to trigger in advance when a specific spot price is reached, known as a limit order. Bitcoin Stack Exchange is one of the first places Optech contributors look for answers to their questions-or when we have a few spare moments of time to help curious or confused users. The payout time is always the end of the day, week or month. Notable changes this week in Bitcoin Core, LND, C-Lightning, Eclair, libsecp256k1, and Bitcoin Improvement Proposals (BIPs). Bitcoin Store is the brand name of Digital As d.o.o.
