Blockstream CEO Adam Back, an early pioneer of the crypto movement, has urged Bitcoiners to develop quantum-resistant solutions to the issue of quantum computing, stating that the threat is still decades away and that the safest approach is to build optional upgrades that allow migration to quantum-proof cryptography if needed.
