Smart Contracts on Liquid: From Zero to Hero

@brqgoo, Marco Argentieri (tiero)

Time: Tue, Jun 7 · 9:30 AM – 10:30 AM
Location
Type: talk
Duration: 1h

Watch recording

Elements Tapscript, a superset of Bitcoin Script, it allows developers to build secure, efficient and private smart contracts thanks to powerful introspection capabilities, MAST introduced with taproot and the stateless nature of the Bitcoin UTXO model. In this workshop you will learn how to write contracts and create web applications that interact directly with the help of Nigiri, Marina Wallet browser extension and LiquidJS. SETUP: Be sure to have installed on your machine: - Docker - Docker Compose - Node & Yarn/NPM (optional, but highly suggested for advanced web app examples) - Nigiri CLI https://github.com/vulpemventures/nigiri/ Burak: https://twitter.com/brqgoo Tiero: https://twitter.com/tierotiero https://btcpp2022.sched.com/event/12P6E/smart-contracts-on-liquid-from-zero-to-hero

Simplicity: From Bitcoin Script to Arbitrary Computation

Christian Lewe

Time: Tue, Jun 7 · 11:00 AM – 11:50 AM
Location
Type: talk
Duration: 50m

Watch recording

Bitcoin Script is a language that controls the spending of coins. However, there are various alternatives that strive to be better: Ethereum's Solidity can express all computable functions and allows for more introspection into spending transactions. Due to Turing completeness, static analysis is limited. Miniscript is a declarative language that corresponds to a subset of Bitcoin Script. It allows powerful static analysis, including a complete enumeration of all spending paths as well as guarantees about resource limits. The language can express at most what Bitcoin Script can express. A question arises: Can we design a language with higher expressivity, like Solidity, that has integrity and verifiability like Miniscript? Simplicity is a functional language developed by Russel O'Connor since 2015, which we hope to deploy on the Liquid network soon. It can implement powerful smart contracts, since it can express all Boolean functions. Meanwhile, it is verifiable and admits resource bounds. The language is implemented for the Coq proof assistant, which enables machine-verified proofs of arbitrary statements about a given Simplicity program. APIs in C, Rust and Haskell are in the making. In this talk, we give a general introduction to Simplicity. We explain the structure of a Simplicity program and look into how it can be used in practice. We draw parallels to Bitcoin Script and sketch a translation to Simplicity.

Set reconciliation is an efficient technique to synchronize data across a network. In this presentation we review the role of gossip in the lightning network, and the current state of the network. We’ll then introduce some theory behind the Minisketch set reconciliation library, as well as how it’s used in practice. Finally, we’ll come back around to how this can improve the lightning network and what work is currently being done to integrate Minisketch into the lightning network protocol.

Hand-Computed Checksums and Secret Sharing

Andrew Poelstra

Time: Wed, Jun 8 · 9:30 AM – 12:00 PM

Type: talk
Duration: 2h 30m

Watch recording

Will work through a variant of "codex32", a volvelle (paper computer) based scheme for generating and verifying checksums; splitting and recovering secrets; encrypting and decrypting them. Throughout we will avoid the use of electronic computers, whose complexity and lack of transparency make them a liability for long-term cold storage. Codex32 is designed to work with 128-bit keys. Because of a current lack of wallet support, and time constraints, we will instead work through the processes for 32- or 48-bit keys.

You'll get SSH access to a pre-setup Linux cloud machine. I'll need an SSH pubkey from you. You can generate a new key pair with `ssh-keygen -t ed25519 -C "btc++-workshop"`. Please send me only (!) the public key part (ending in `*.pub`) the night before. I won't be able to provision a cloud machine for you without a SSH pubkey. You should have basic knowledge of the Linux command line and be able to read and write simple Python code. Being able to compile Bitcoin Core from source (autoconf + configure + make) will be helpful, but isn't a hard requirement. https://b10c.me https://btcpp2022.sched.com/event/12P6o/tracing-bitcoin-core-v230
