How to get Started with BNB Smart Chain (BSC)

This has sparked all sorts of innovation - there are many more Bitcoin wallet and point-of-sale devices than the ones I’ve mentioned here, and there are certainly more to come. ● What are packages in Bitcoin Core and what is their use case? Antoine Poinsot explains that script descriptors are currently being extended to use miniscript in Bitcoin Core and are expected in the Bitcoin Core 24.0 release. While initial miniscript features will only include segwit v0 support, eventually support for tapscript and partial descriptors could make it possible to add commitments inside tapscript without solely using the raw() descriptor. Although it’s already possible to refer to the key in those cases using the existing raw() descriptor, which is primarily meant to be used with tools like Bitcoin Core’s scantxoutset RPC for scanning its database of UTXOs, the new rawtr() descriptor makes it easier to use other existing descriptor fields to associate additional information with the taproot output such as key origin information. They could then allocate their deposit funds according to the contract without even telling the oracle that they were planning to use it. The most significant of these is that it would allow "stateless" oracles where the parties to a contract (but not the oracle) could privately agree on what information they wanted the oracle to attest to, e.g. by specifying a program written in any programming language they knew the oracle would run.

23480 updates the output script descriptor language with a rawtr() descriptor for referring to the exposed key in a taproot output in cases where either the key is used without a tweak (not recommended, see BIP341) or when the internal key and scripts aren’t known (which can be unsafe; see the PR comments or the documentation added by this PR for details). RETURN commitment (or some arbitrary script) inside a taproot script path with a descriptor? A previous proposal, BIP322, to provide fully generic message signing that could work with any script has not yet been merged into Bitcoin Core or added to any other popular wallet of which we’re aware. Stickies-v provides an overview of Bitcoin Script operators, how taproot enabled with MAST improves upon spending conditions from a privacy and feerate perspective, and points out that Script’s lack of covenants makes the proposed conditions impossible solely in Script. Pieter Wuille points out the P2P network’s lack of transaction propagation guarantee as the reason for rebroadcasting being necessary and notes work done to remove rebroadcasting responsibilities from the wallet to the mempool. Pieter Wuille explains that this behavior, defined in BIP340-342, is designed to support batch validation of schnorr signatures in the future.

Antoine Poinsot explains packages (a grouping of related transactions), 바이낸스 - simply click Strong Juarez Thoughtlanes - their relation to package relay, and a recent package relay BIP proposal. The onion message protocol doesn’t require a node which relays an onion message to track any information about that message after relay, so it can’t automatically send a reply back along the path the original message took. That means a node which wants a reply to its onion message needs to provide hints to the receiver about what path to use for sending a reply. 1652 updates support for onion messages with the ability to send reply paths, and to decode them when received. 2387 adds support for signet. 2275 adds support for fee bumping a dual funded LN setup transaction. 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. 627 adds support for P2TR keypath spends using the BitBox02 hardware signing device.

22751 adds a simulaterawtransaction RPC which accepts an array of unconfirmed transactions and returns how much BTC those transactions will add or subtract from the wallet’s balance.
