The World Crypto Network Podcast

In the last diary entry, we focused on building a very simple mesh network with broadcast and unicast capabilities. https://www.youtube.com/watch?v=3DN4L... In this entry, I experiment with range and try and broadcast data across 1.2km of the bitcoin mesh network. The eventual goal is to be able to blanket my local village in bitcoin transaction data, to be able to send, receive and broadcast bitcoin transactions using a freely accessible, censorship-resistant, self-healing, self-organising mesh 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: * 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

This week’s newsletter highlights some of the changes in the recently-released Bitcoin Core 0.18.0, briefly mentions two proposed BIPs, describes how bech32 addresses are forward compatible with expected protocol improvements, and summarizes notable changes in popular Bitcoin infrastructure projects. https://bitcoinops.org/en/newsletters... The Bitcoin Operations Technology Group (Optech) works to bring the best open source technologies and techniques to Bitcoin-using businesses in order to lower costs and improve customer experiences. An initial focus for the group is working with its member organizations to reduce transaction sizes and minimize the effect of subsequent transaction fee increases. We provide workshops, documentation, weekly newsletters, original research, case studies and announcements, and help facilitate improved relations between businesses and the open source community. https://bitcoinops.org/ 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...
