Blockchain
A blockchain is an append-only replicated ledger with a consensus rule — a database with an incentive system, not a price target.
Definition
Blockchain refers to only replicated ledger with a consensus rule — a database with an incentive system, not a price target. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Crypto liquidity and leverage regimes can gap faster than traditional risk systems assume. When only replicated ledger with a consensus rule — a database with an incentive system, not a price target shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what blockchain is saying. If only replicated ledger with a consensus rule — a database with an incentive system, not a price target moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Treat venue, leverage, and stablecoin plumbing as first-class risk — not afterthoughts. Prefer a short written null hypothesis for Blockchain: what would falsify the current reading in the next window?
