Ideas CHIP: Targeted Virtual Machine Limits By fixing poorly-targeted limits, we can make Bitcoin Cash contracts more powerful (without increasing validation costs).
PMv3 AMA on r/btc: Build Decentralized Apps on Bitcoin Cash with PMv3 I was r/btc on Reddit on May 2, 2021 for an AMA (Ask Me Anything). Some topics covered included prediction markets, PMv3, CashTokens, and Bitcoin Cash development.
PMv3 PMv3 CHIP Revised: Version 3 Transactions The PMv3 proposal has been revised and is now a Cash Improvement Proposal: CHIP-2021-01-PMv3. Review and feedback is appreciated.
Videos Video: Prediction Markets on Bitcoin Cash I spoke with George Donnelly about hashed witnesses, PMv3, CashTokens, prediction markets, synthetic assets, decentralized exchanges, BCH scaling considerations, comparisons with ETH, and more.
PMv3 PMv3: Build Decentralized Applications on Bitcoin Cash Bitcoin Cash is already powerful enough to build and scale many applications planned for “global state” systems like Ethereum.
CashTokens PMv3-Based CashTokens A post describing the original 2020 implementation of contract-validated tokens for Bitcoin Cash. Superseded by the CashTokens CHIP.
Ideas Prediction Markets on Bitcoin Cash By cutting through misinformation, prediction markets can save lives, root out corruption, and revolutionize industries.
Ideas RFC: AllowReplay–Safer Splits for Bitcoin Cash AllowReplay allows users to opt-in to replay protection on a per-signature basis, and it’s strictly beneficial to the implementing network.

Libauth Just released: SHA-256, SHA-512, SHA-1, and RIPEMD-160 using WebAssembly TL;DR: up to 20x better performance than JavaScript, and up to 4x faster than Node.js native bindings for small inputs. (But you should look at the benchmarks yourself.) You can now import WebAssembly implementations of the cryptographic hash functions used in cryptocurrencies like Bitcoin and Bitcoin Cash from
Libauth Just released: WebAssembly version of Secp256k1 (10x faster than Javascript) Bitcoin, Bitcoin Cash, and most other cryptocurrencies use the Elliptic Curve Digital Signature Algorithm (ECDSA) [https://en.wikipedia.org/wiki/Elliptic_Curve_Digital_Signature_Algorithm] to authenticate transactions. ECDSA can be used with a number of different elliptic curves [https://en.wikipedia.org/wiki/Elliptic-curve_cryptography], and Bitcoin’s creator
