Bitcoin's threat model mapped end-to-end: what the protocol trusts, what it defends against, how each attack is countered, and where open risks remain.
Adam Back's reply to a question about whether Bitcoin faces near-term risk from quantum computing, pointing at NIST-standardized SLH-DSA and a 20–40 year horizon.
Which Bitcoin assets are at risk from a cryptographically relevant quantum computer, and what the timeline and migration debate around post-quantum cryptography looks like.
Pay-to-Merkle-Root (P2MR), a quantum-resistant output type. Like Taproot without the quantum-vulnerable key path spend — commits only to the Merkle root of a script tree. SegWit v2, soft fork.
Blockstream CEO Adam Back stated Bitcoin faces no quantum computing threat for ~20–40 years, pointing to NIST post-quantum signatures like SLH-DSA that Bitcoin can adopt before threats materialize.
