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. The proposed protocol contains a significant number of differences from Wasabi’s current protocol (such as replacing blind signatures with keyed-verification anonymous credentials), so its authors are seeking review, criticism, and suggestions about how the protocol can be used most effectively. ● Evaluate proposed changes to BIP341 taproot transaction digest: as described in last week’s newsletter, there has been a request for taproot signatures to make an additional commitment to the scriptPubKeys of all the UTXOs being spent in a transaction. If you have any questions or concerns about the proposed transaction digest revision, we suggest either replying to the mailing list or contacting the BIP341 authors directly. This week, several contributors to Wasabi posted to the Bitcoin-Dev mailing list about a new protocol they call WabiSabi that conceptually extends their existing protocol with a technique adapted from confidential transactions.
The previous standard protocol uses four transactions. The coordinator uses this specified value to verify that the sum of the outputs the client wants to create is equal to the sum of the inputs provided by the client (minus fees). ● Wasabi uses a centralized coordinator who organizes every coinjoin made using that software. ● Lightning-based messenger application Juggernaut launches: In a blog post announcing the first release of Juggernaut, John Cantrell describes how the messaging and wallet features are built using keysend payments. ● Desktop version of Blockstream Green wallet: Blockstream has released their Green wallet for desktop on macOS, Windows, and Linux. However, a previous change expected to be released as part of 0.19.0 in the next month or so will switch the default address type for GUI users to also use bech32 P2WPKH. 45:16 Aaron Ross Powell: Diego, those advantages that you listed for Bitcoin, not the first mover ones, but the fact that it doesn’t have a person making pronouncements and an organization that’s running it, are those also disadvantages for 바이낸스 its long-term use in the sense that they don’t allow it or they make it much harder for Bitcoin as a protocol, as kind of a piece of software to evolve and upgrade so that it can’t change to like, so Bitcoin is not, doesn’t have privacy baked into it and so we can’t…
Anthony Towns has suggested how BIP341 might be updated for this change and Pieter Wuille has asked whether anyone has any objections. Instead, Wasabi requires that all outputs either belong to a small set of allowed sizes (e.g. 0.1 BTC, 0.2 BTC, 0.4 BTC, etc) or be an unblinded change output. This isn’t a security risk-the other participants will refuse to sign any malformed transaction-but such a failure requires restarting the protocol. ● Blockstream Satellite 2.0 supports initial block download: 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. In that sense, the protocol acts as a sort of generalized channel factory that applies not just to LN but to many protocols that create onchain transactions with unique fingerprints. Using taproot, this allows the cooperating participants to operate protocols such as LN or vaults using UTXOs that are indistinguishable from single-key UTXOs, improving both participant privacy and onchain scalability. ● 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).
Bitcoin is a digital currency which was invented for online monetary exchange and is an important part of E-commerce industry. Some promise astronomical (and implausible) returns and fail to disclose a range of hidden fees, while others are fronts for Ponzi scams and are simply designed to part you from your money. For example, a taker can choose the amounts of the coinjoin they want to create or can spend their money to a third party as part of a coinjoin. Makers who want guarantees about their privacy can always operate as takers for a few rounds of mixing. The coordinator can then provide an anonymous credential for each output that allows the client to later anonymously submit the output to the coordinator for inclusion in the transaction template. Switching to native segwit in order to reduce a transaction’s weight allows you to reduce its fee by the same percentage without changing how long it’ll take to confirm-all other things being equal.
