BTQ Unveils BIP 360 in Bitcoin Quantum Testnet

BTQ Technologies unveiled the latest version of its Bitcoin Quantum testnet on Thursday, marking the first live implementation of Bitcoin Improvement Proposal 360, a key upgrade designed to shield the network from potential future quantum computing attacks. The release, version 0.3.0, provides developers with a functional testing environment to experiment with quantum-resistant transactions, advancing efforts to secure Bitcoin's cryptographic foundations.

At the heart of the upgrade is BIP 360, also known as PaytoMerkleRoot or P2MR, which introduces a new transaction output type. Bitcoin's current system relies on elliptic curve digital signature algorithm, or ECDSA, to protect wallets by linking private keys to public keys. While effective against classical computers, this cryptography could be vulnerable to a sufficiently advanced quantum computer using Shor's algorithm to derive private keys from exposed public keys. Such an attack would allow unauthorized access to funds, though no quantum machine capable of this exists today.

BIP 360 addresses the issue by committing transactions directly to the Merkle root of a script tree, rather than revealing public keys through...
