Software security, markets, and bitcoin cash.
Thanks to Emmanuel Musa and Bitcoin.com News for this article: Quantumroot Debuts on Bitcoin Cash: First Post-Quantum Vault on Bitcoin Script Developer Jason Dreyzehner has unveiled Quantumroot, the first fully implemented, integration-ready post-quantum vault system. The full interview: You’ve been leading development on Bitcoin
Quantumroot vaults are now live on Bitcoin Cash's 6-months-ahead preview network. Contracts, testing suite, and transaction generation code now available.
The 2026 upgrade completes the restoration of Bitcoin Script on Bitcoin Cash (CashVM), making CashVM a simple, ultra-efficient, high-level programming environment for sound money.
I joined the Bitcoin Cash Podcast to talk about the 2026 CHIPs, Quantumroot, and zero-knowledge proofs on Bitcoin Cash.
An video introduction and walk-through of Quantumroot: Quantum-Secure Vaults for Bitcoin Cash.
A new contract design offers full 256-bit classical, 128-bit quantum security strength. Quantum spends are ~1.5KB per UTXO, and with cross-input and CashToken-based aggregation, quantum sweeps of 400+ unique addresses or 800+ inputs fit in a single transaction (100KB).
I joined the Bitcoin Cash Podcast to talk about Bitcoin Cash Improvement Proposals (CHIPs) for Loops, Functions, Pay-to-Script, a potential transaction format upgrade, and more.
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.
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 –
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.

I recommend the VM Limits & BigInt CHIPs for activation in Bitcoin Cash's 2025 upgrade.
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).
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).
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.
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.
