Schnorr BIP, Taproot BIP, Tapscript BIP ~ bitcoin-dev Mailing List May 07, 2019

Show notes

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: * https://github.com/sipa/bips/blob/bip... specifies the transaction input spending rules. * https://github.com/sipa/bips/blob/bip... specifies the changes to Script inside such spends. * https://github.com/sipa/bips/blob/bip... is the Schnorr signature proposal that was discussed earlier on this list (See https://lists.linuxfoundation.org/pip...) https://lists.linuxfoundation.org/pip... https://twitter.com/pwuille

Organizing Bitcoin Family Gatherings ~ Kevin Loaec ~ Understanding Bitcoin May 03, 2019

Show notes

BREAKING BITCOIN Conference, Amsterdam, 8-9 June 2019. Breaking Bitcoin is an event for the technical community focusing on the security of Bitcoin and everything around it. Presentations aim to be technical, focusing on vulnerabilities, theorical or practical attacks targetting the users and the Bitcoin protocol. This event is geared toward people with knowledge of the technical aspects of Bitcoin or security in general. Following the conference, a Training, a work together and a Hackathon are organized! https://breaking-bitcoin.com/ Understanding Bitcoin conference is organized with a focus on the non-technical, non-developer users that want to increase their knowledge and technical participation in the Bitcoin network. Not everyone has the skills to take full advantage of what Bitcoin has to offer, so this event will help the average user be more familiar with best practices and understanding all aspects of interacting with the Bitcoin network. There will be practical hands on presentations of how to set up features, along with theoretical discussions removing the FUD and misconceptions surrounding the current state of Bitcoin’s Trustless Network. https://understandingbtc.com/ If you have learned something valuable, donate a couple sats to Max as a thank you note: 3DqEnU6dW6bZesrVdThrrQjQKgN7dpY5vv https://tallyco.in/HillebrandMax Support the show by buying bitcoin on https://hodlhodl.com/join/ERCT Listen to WCN Audio Podcasts: https://itunes.apple.com/us/podcast/t...
