- Bech32mGlossary · Bech32m is the checksummed address encoding defined in BIP 350; it fixes a bech32 weakness and encodes taproot addresses as well as BTX addresses.
- ECDSAGlossary · ECDSA is the elliptic-curve digital signature used by Bitcoin and TLS; its discrete logarithm security falls to Shor's algorithm on a quantum computer.
- Is Bitcoin quantum safe?Blockchain · An evidence-based look at Bitcoin's quantum exposure: which coins have revealed public keys, how fast an attacker must be, and the proposed fixes.
- Quantum computers and proof-of-work miningBlockchain · Grover's algorithm gives only a quadratic speedup on proof-of-work hashing, so quantum mining stays impractical against ASIC fleets for the foreseeable future.
- Taproot and quantum key exposureBlockchain · Taproot P2TR outputs place an x-only public key directly on chain, so taproot coins are quantum-exposed at rest, unlike hash-guarded legacy addresses.
- UTXOGlossary · A UTXO is an unspent transaction output; the UTXO ledger model limits public key exposure per output, which shapes quantum risk on Bitcoin-style chains.
