    <br> 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. Also included are our regular sections with popular questions and answers from the Bitcoin Stack Exchange, announcements of new releases and releases candidates, and summaries of notable changes to popular Bitcoin infrastructure software. This week’s newsletter describes a proposal to allow multiple derivation paths in a single output script descriptor and includes our regular section with summaries of notable changes to popular Bitcoin infrastructure projects. ● Multiple derivation path descriptors: Andrew Chow posted a proposed BIP to the Bitcoin-Dev mailing list for allowing a single descriptor to specify two related BIP32 paths for HD key generation. Andrew Chow gives an additional reason for the behavior, noting that certain malleability concerns are also mitigated by this approach. ● Mining stale low-difficulty blocks as a DoS attack Andrew Chow explains that assumevalid and more recently nMinimumChainWork help filter out low-difficulty chain attacks.
    Replies from Pavol Rusnak and Craig Raw indicated that Trezor Wallet and Sparrow Wallet already supported the scheme Chow proposed. This week’s newsletter describes a proposed BIP for creating signed messages for non-legacy addresses and summarizes a discussion about provably burning small amounts of bitcoin for denial of service protection. Several solutions were discussed using merkle trees, although one respondent suggested that the small amounts involved suggest that having participants trust (or partially trust) a centralized third party may be a reasonable way to avoid unnecessary complexity. 627 adds support for P2TR keypath spends using the BitBox02 hardware signing device. If the example webserver were compromised and the external addresses were leaked, the attacker would learn about each time the user received money, how much they received, and when they initially spent the money-but they wouldn’t necessarily learn how much money was sent in the initial spend, and they also might not learn about any spends that entirely consisted of spending change. Dmitry Petukhov noted that only internal and external paths are widely used today and that any additional paths wouldn’t have a clear meaning to existing wallet<br>/p>
    As specified in BIP32, most wallets use separate paths for generating external versus internal addresses in order to enhance privacy. An external path used for receiving payments might be shared with less-trusted devices, e.g. uploading it to a webserver to receive payments. The internal path used only for change might only be needed at times when the private key is also needed, so it could receive the same security. ● Multiformat single-sig message signing: Bitcoin Core and many other wallets have long included support for signing and verifying arbitrary messages when the key used to sign them corresponds to a P2PKH address. Bitcoin Core doesn’t support signing or verifying arbitrary messages for any other address type, including addresses covering single-sig P2SH-P2WPKH, native P2WPKH, and P2TR outputs. At present, it supports several utilities for the Binance community, including paying for market maker fees, trade fees, listing fees, and other such fees on the Binance market. RETURN or scripts larger than the max script size are removed from the UTXO set, removing uneconomical outputs could cause issues, including a hard fork as Pieter Wuille points out, if those outputs <br>s<br>t.
    Similar to other efforts to modularize areas of the Bitcoin Core codebase like libbitcoinkernel or process separation, Pieter Wuille notes a clear area of responsibility of the libsecp256k1 project: everything that involves operations on private or public keys. Pieter Wuille explains that this behavior, defined in BIP340-342, is designed to support batch validation of schnorr signatures in the future. Developer Peter Gray noted that ColdCard wallets already create signatures in this way and developer Craig Raw said Sparrow Wallet that wallet is able to validate them in addition to also following the BIP137 validation rules and a slightly different set of rules implemented in Electrum. In March 2018, Japanese Newspaper Nikkei reported that Binance was trading in Japan and not following their official regulations. Nonetheless, making it easier for more individuals to buy from and invest with you and https://www.youtube.com/@Coin_universe cashing in on the dramatic increase in Bitcoin price make this trading asset quit<br>luable.
