Assess cryptographic lag regimes, Mosca horizons (X+Y>Z), UTXO vulnerability tiers, and PQC signature bloat
Vulnerability depends heavily on static on-chain public-key exposure vs unspent hash commitments:
| Format / Scenario | Exposed Key? | Shor Threat | Grover Threat | Risk Tier |
|---|
Direct full public key committed in scriptPubKey. Immediate private-key recovery possible under Shor's Discrete Logarithm crack. Estimated ~1.7M BTC dormant in this state.
Replaces hardcoded secp256k1 EOA authentication with signature-agile smart contract accounts, enabling hybrid classical/lattice verification without contentious hard forks.
Deprecates pairing-dependent BLS consensus signatures for hash-based leanXMSS, running inside leanVM zkVM to compress bulky multi-kilobyte signatures back to classical scale.
Transitions blob data availability and polynomial verification from discrete-log KZG setups into collision-resistant, post-quantum hash-based STARK systems.
Replacing 64-byte ECDSA with NIST FIPS standards inflates witness data, capping transactions-per-second and elevating fee baselines.
Deterministic synthesis based on active portfolio & cryptographic parameters
P2PK & Address-Reused P2PKH susceptible to static Shor key recovery.
Pristine P2WPKH hashes safe until broadcast signature reveals public key.
Consolidate dormant UTXOs into Merkelized PQ addresses & setup hybrid wallets.
