Videos 2026 & 2027 proposals: OP_EVAL, P2S, Loops, and TXv5 I joined Fiendish & Friends Podcast #11 to talk about Bitcoin Cash Improvement Proposals (CHIPs) for 2026 and 2027: OP_EVAL, Pay-to-Script, loops, and TX version 5.
Ideas 2027 Proposal: Transaction Version 5 Today I'm proposing CHIP-2025-01 TXv5: Transaction Version 5: - Zero-Overhead Covenants – Enable user-deployed financial and privacy covenants to minimize transaction sizes, matching or outperforming purpose-built, "layer 1" networks. See Example: Zero-Knowledge Proof Covenants. - Detached ("Cross-Input") Signatures – Reduce transaction sizes by enabling multiple inputs
Ideas 2026 Proposals: Loops, Functions, and Pay to Script Proposing three CHIPs for Bitcoin Cash's 2026 upgrade: loops, function eval, and Pay to Script (P2S). These would make BCH contracts more efficient than ETH, SOL, etc. across some remaining gaps + optimize transaction sizes for zero-knowledge and post-quantum covenants.

Ideas 2025 Bitcoin Cash Improvement Proposals I recommend the VM Limits & BigInt CHIPs for activation in Bitcoin Cash's 2025 upgrade.
Videos General Protocols Space #34: Ask Me Anything I joined General Protocols Space #34 to talk about Virtual Machine Limits, BigInt, the CHIP upgrade process, BCH vs. ETH, decentralized exchanges, and instant finality with Zero-Confirmation Escrows (ZCEs).
Videos Bitcoin Cash Podcast #130: VM Limits & BigInt I joined the Bitcoin Cash Podcast to talk about the Virtual Machine Limits & BigInt CHIPs, the CHIP upgrade process, and instant finality with Zero-Confirmation Escrows (ZCEs).
Videos Bitcoin Cash Podcast #122: Virtual Machine Limits I joined the Bitcoin Cash Podcast to talk about the history and rationale behind the VM Limits & BigInt CHIPs, directions for future protocol development, and instant finality with Zero-Confirmation Escrows.
Software Bitauth IDE v1.0.0 Released The first long-term stable (LTS) release of Bitauth IDE, v1.0.0, is now available. This upgrade significantly improves performance, enables offline usage, and clears the way for future development.
Software Libauth v2.0.0 Released Libauth v2.0.0 is now available, and the library has reached over 1 million annual downloads, with consistent growth in daily downloads.
Software Bitcoin Cash Upgrade 2024 Libauth, Chaingraph, and Bitauth IDE support one Cash Improvement Proposal (CHIP) for the 2024 Bitcoin Cash Upgrade.
Videos Bitcoin Cash Podcast #79: CashTokens Creation I joined the Bitcoin Cash Podcast to talk about the history behind CashTokens, Bitcoin Cash technical infrastructure, and directions for future development.
Ideas Comments on the 2023 Upgrade to Bitcoin Cash "Suddenly it was possible to build very efficient, UTXO-based decentralized applications while preserving important features of Bitcoin Cash: stateless transaction validation (low fees) and zero-delay re-spending (fast transactions)."
Ideas Bitcoin Cash Metadata Registries Bitcoin Cash Metadata Registries share metadata between Bitcoin Cash wallets, allowing user-recognizable names, descriptions, icons, ticker symbols, etc. to be associated with on-chain artifacts like identities, tokens, and contract systems.
Software Bitcoin Cash Upgrade 2023 Bitauth.com open source software will support four Cash Improvement Proposals (CHIPs) for the 2023 Bitcoin Cash Upgrade.
Software Jedex: Decentralized Exchanges on Bitcoin Cash Jedex is a technical demonstration of a massively-parallel, non-custodial, censorship-resistant decentralized exchange (DEX) built directly on Bitcoin Cash using CashTokens.
Videos Bitcoin Cash Upgrade 2022 Livestream I joined the Bitcoin Cash Upgrade 2022 Livestream hosted by Satoshi's Angels to answer questions and discuss new use cases made possible by the upgrade.
Videos BCH Network Discussion: May Upgrade and Beyond I joined the March 2022 BCH Network Discussion about the Cash Improvement Proposal (CHIP) process, May 2023 Upgrade, and potential future upgrades.
Ideas CashTokens: Token Primitives for Bitcoin Cash CashTokens enable decentralized applications comparable to Ethereum contract functionality, while retaining Bitcoin Cash's >1000x efficiency advantage in transaction and block validation.
Software Bitcoin Cash DNS Seeds Two new DNS seeds are now available for Bitcoin Cash:bch.bitjson.com for the main network and testnet4.bitjson.com for the test network. DNS seeds are web addresses included in Bitcoin Cash software to help new users find and join the peer-to-peer network. To test each seed, try
Software Bitcoin Cash Upgrade 2022 All Bitauth open source software – including Libauth, Bitauth IDE, and Chaingraph – will provide support for the 2022 Bitcoin Cash upgrade.
Chaingraph Chaingraph: Multi-Node Bitcoin Cash Indexer The first release of Chaingraph – a new, open source indexer and API backend for Bitcoin Cash apps and businesses – is now available.
Videos BCH Network Discussion: Introspection I joined the September 2021 Bitcoin Cash Network Discussion about introspection opcodes. These opcodes enable far more secure wallets, efficient recurring payments, and more.
Ideas CHIP: ZCEs – Instant, Secure Payments on Bitcoin Cash Zero-Confirmation Escrows (ZCEs) enable instant, incentive-secure payments on Bitcoin Cash. They require no setup delay or ongoing relationship, and can be safely accepted without a waiting period.
Ideas CHIP: Ranged Script Numbers The Ranged Script Number (RSN) format is derived from the existing Script Number format used within the BCH VM, but it includes a prefix which allows RSN values to be safely parsed from serialized transaction messages.
Ideas CHIP Revised: Bigger Script Integers A new revision to the Bigger Script Integers CHIP has been published. This revision adds a full technical specification and an extensive Rationale section documenting design decisions made in the specification.
