“Researchers at Blockstream, a bitcoin infrastructure firm whose engineers have contributed to the Bitcoin blockchain’s core software for more than a decade, published a proposal on Thursday for SHRINCS, a way of signing bitcoin transactions that could withstand quantum computers without sharply reducing the number of transactions that fit in a block. Bitcoin proves ownership using digital signatures built on a branch of mathematics known as elliptic-curve cryptography. Those signatures allow someone to prove they hold the private key controlling their bitcoin without revealing the key itself. But it is theorized that a sufficiently powerful quantum computer … could eventually break that protection. … The proposal comes as Ethereum researchers moved in the same direction earlier this week, proposing changes to the system validators use to deposit funds so it can eventually accept new types of cryptographic keys.” (08/27/26)
