Bitcoin Quantum-Resistant Upgrades Gain Momentum Amid Solana's Disinflation Vote
Bitcoin's quantum-resistance is taking shape through layered experiments that tackle specific threat windows. StarkWare researcher Avihu Levy recently tested an experimental quantum-resistant Bitcoin transaction on mainnet, using a scheme designed to protect outputs during the mempool exposure window.
The approach combines hash-based one-time signatures with computational search techniques that bind an authorization to a specific transaction. However, each transaction reportedly took hours to complete and cost an estimated $150 to $200.
Meanwhile, Blockstream researchers published a Bitcoin Improvement Proposal (BIP) introducing the SHRINCS signature scheme, which significantly shrinks a large hash-based post-quantum signature while still introducing trade-offs.
Solana validators approved 'Double Disinflation' (SGP-0002), doubling annual disinflation to target 1.5% terminal inflation in about 2.8 years. This decision is expected to reduce issuance by 18.9 million SOL over the next six years.
