World Crypto Network: Introduction to the Taproot BIP ~ bitcoin-dev Mailinglist © World Crypto Network
Here are two BIP drafts that specify a proposal for a Taproot softfork. A number of ideas are included: * Taproot to make all outputs and cooperative spends indistinguishable from eachother. * Merkle branches to hide the unexecuted branches in scripts. * Schnorr signatures enable wallet software to use key aggregation/thresholds within one input. * Improvements to the signature hashing algorithm (including signing all input amounts). * Replacing OP_CHECKMULTISIG(VERIFY) with OP_CHECKSIGADD, to support batch validation. * Tagged hashing for domain separation (avoiding issues like CVE-2012-2459 in Merkle trees). * Extensibility through leaf versions, OP_SUCCESS opcodes, and upgradable pubkey types. The BIP drafts can be found here: * specifies the transaction input spending rules. * specifies the changes to Script inside such spends. * is the Schnorr signature proposal that was discussed earlier on this list (See If you have learned something valuable, donate a couple sats to Max as a thank you note: 3Fe6dcwhkLnMo7c2FrkYduR5xJgo38dTTS Support the show by buying bitcoin on Listen to WCN Audio Podcasts: Check out the brand new Find out more about Max Follow WCN on Twitter: Follow Max on Twitter: Contribute to Max’s Bachelor Thesis on Multi Signature in the Lightning Network: Bitcoin to the Max: Bitcoin Only: Read Rothbard ~ Use Bitcoin: Open Source Everything: Breaking Bitcoin 2019: Hackers Congress Paralelni Polis 2018: Baltic Honeybadger 2018: Understanding Bitcoin 2019: Bitcoin-Dev Mailing List: Schnorr: Nodl Personal Bitcoin Assistant: Bisq Decentralized Exchange: ColdCard Wallet: GPG + Yubikey: Purism: Bitcoin Op Tech Newsletter: The Ethics of Money Production: What Has Government Done to Our Money?
