GLOSSARY
Every term, defined plainly.
Protocol V4 introduces vocabulary that matters for integrators and exchanges. Each term below maps to something you can verify on your own node or in the explorer.
- Protocol V4 — Quantum Quasar
- The scheduled protocol upgrade adds the Gold Rush accounting overlay, a post-quantum signature migration path, and new staking tiers on top of inherited Blackcoin chain history. Software release milestones and consensus activation heights are separate.
- Proof-of-Stake (PoS)
- The consensus mechanism: mature coins in a running, unlocked wallet "stake" to mint blocks and earn rewards, instead of PoW mining. Blackcoin's last PoW block was height 10,000.
- Gold Rush
- A scheduled Protocol V4 phase that records synthetic credit on the shadow ledger via transaction-carried Argon2id PoW claims and PoS distributions. PoW claim computation does not produce base-chain PoW blocks, and synthetic credit is not a spendable balance during Gold Rush.
- Shadow ledger / shadow record
- A separate accounting layer, anchored to real base-chain blocks, that tracks Gold Rush synthetic credit. A shadow record is one entry on it — a PoW claim or PoS distribution — identified by a synthetic txid.
- Phase-locked synthetic credit
- Gold Rush credit that is recorded but not spendable during Gold Rush. From Migration height 6,193,000, authenticated unspent credits may become spendable when output maturity and all applicable consensus and authorization conditions are satisfied. The earliest eligible height is
max(maturity_height, 6193000), not a new blanket maturity period after Migration starts. A record alone does not establish a winning award, current spendability, exchange support, or guaranteed yield. - Synthetic txid
- The 64-hex identifier of a shadow record. It is not a base-chain transaction id; it addresses an entry on the shadow ledger (e.g. at
/explorer/shadow/tx/<id>). - Anchor / anchor height
- The real base-chain block a shadow record is bound to. "Anchored" means the synthetic entry references a specific, verifiable block height and hash — so it is reproducible on any node.
- PoW claim / PoS distribution
- The two kinds of shadow record. A PoW claim is a Gold Rush claim; a PoS distribution is a staking-side distribution. Synthetic credits are phase-locked and not spendable during Gold Rush; later spendability depends on authentication, unspent status, output maturity, and applicable consensus and authorization conditions.
- Demurrage
- A scheduled decay applied to certain Protocol V4 outputs (e.g. some cold-stake / migration witness types). It reduces an entry's effective amount over time per the consensus rules.
- Migration
- The scheduled transition starting block 6,193,000, when legacy outputs can migrate to the Protocol V4 model and authenticated unspent Gold Rush credits may become spendable subject to output maturity and all applicable consensus and authorization conditions. Governed by block height, not date.
- Competing-claim rule
- The first scheduled differing rule, activating at height 5,993,200: it resolves conflicting Gold Rush claims. Activation at or above that height is not proof of a branch split; compare exact hashes and rule sets.
- Witness v14 / v15 / v16
- Protocol V4 output shapes: v14 quantum cold-stake (owner/staker separated, demurrage-eligible), v15 a reserved EUTXO shape (disabled in production), v16 quantum migration / tiered staking (demurrage-eligible).
- ML-DSA-44 (FIPS 204)
- The post-quantum signature scheme Protocol V4 provides a migration path to. A migration path — not a claim of FIPS validation or absolute security.
- Quorum-verified
- Data agreed by multiple independent observer nodes before this site serves it. The site is a fail-closed mirror of the daemon; it discloses coverage and never presents unavailable or partial data as complete.
- Replay marker
- An integrity attestation the producer writes and the lifecycle endpoint validates, confirming the deployment's replay/consensus schema before data is trusted.
- Canonical anchor
- The observer-accepted deployment view at a stated time and source — a technical designation on this site, not a legal, social, or universal one.
- Base chain vs. shadow
- The base chain is the real, spendable Blackcoin UTXO ledger. The shadow layer is the separate Protocol V4 accounting of synthetic credit. Supply figures always distinguish the two.
