Bitcoin Prepares for Quantum Future as Solana Cuts Inflation

Bitcoin developers are pushing forward with post-quantum upgrades to protect transactions from potential quantum computer attacks. Despite some skepticism about the imminent threat, researchers have been working on various solutions, including an experimental transaction protection scheme developed by StarkWare researcher Avihu Levy.

The Quantum Safe Bitcoin (QSB) scheme combines hash-based one-time signatures with computational searches that bind authorization to specific transactions, offering protection during the brief period when public keys are exposed in the mempool. However, it's a last-resort measure, as each transaction takes hours and costs between $150 to $200.

Another long-term upgrade proposal involves implementing the SHRINCS signature scheme, which has been slimmed down by about 13.23 times from its original size. While this is still nine times larger than Bitcoin's existing signatures, Blockstream Research's Jonas Nick called it a 'good trade-off' among available options.

Meanwhile, Solana validators have approved a proposal to double the network's annual disinflation rate, reducing issuance by 18.9 million SOL over six years and bringing inflation down to 1.5% in approximately 2.8 years.
