Hourglass V2 and BIP-361: Plans to Shield Bitcoin From Quantum Attacks

  • —Hourglass V2 would limit spending from P2PK addresses to 1 BTC per block
  • —Full migration of such coins would take at least 32 years
  • —BIP-361 proposes freezing ECC signatures at a fixed block height
  • —An estimated 2–3 million BTC are lost due to missing private keys
Why it matters: The outcome will determine whether a quantum attacker could seize a large share of BTC supply and affect the network's value.
