Primes¶
- Access Friction
- In proof-of-work systems, the protocol requires expending computation to participate, deliberately making entry costly to resist Sybil attacks.
This sourceSpecifies proof-of-work — finding a nonce so a block's hash falls below a target by expending computation, with difficulty auto-adjusting to a fixed block rate — as a deliberately costly entry requirement that makes Sybil-style identity flooding economically infeasible.

- Immutability
- And because the canonical record is fixed, tampering is detectable: any alteration is either impossible (the original is referenced elsewhere) or self-evident (it produces a different hash, a new entry, a fresh instrument).
This sourceWhitepaper. Introduces an append-only hash-chained ledger in which editing any prior block invalidates every subsequent block, making history structurally fixed and tampering self-evident—trust without a trusted editor, the abstract payoff of immutability instantiated cryptographically.

- Provenance
- Cryptocurrency & NFT: On-chain provenance (transaction history of blockchain artifacts, public key signatures verifying transfers), the architecture Nakamoto (2008) introduced in the Bitcoin whitepaper; NFT provenance often problematic—the blockchain records token transfer but not the authenticity or original creation of the underlying asset.

- Verifier-Prover Asymmetry
- The identical move recurs across substrates: a scientific journal that switches from staff-written articles to externally-submitted, peer-reviewed papers is outsourcing the expensive finding (original research) to a wide author population while centralising the cheaper verification (refereeing); a cryptocurrency network's proof-of-work makes finding a valid block deliberately expensive while any node verifies a submitted block almost for free, an engineered gap that lets a large untrusted finding population coexist with cheap universal verification.
