| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Encryption (Modern Cryptography, Public Key) (encryption_modern_cryptography_public_key) | required | 90% | primary_source | The Bitcoin design uses digital signatures and public keys to transfer ownership of electronic coins. |
|
| Cryptographic Hash Functions (cryptographic_hash_functions) | required | 94% | primary_source | The design depends on hash-based proof-of-work and a hash-linked timestamp chain. |
|
| Internet (internet) | enabling | 84% | primary_source | The system is specified as peer-to-peer electronic cash with transactions and blocks broadcast to network nodes. |
|
| Personal Computers (personal_computers) | common_dependency | 68% | primary_source | The 2008 design assumes commodity node hardware and CPU proof-of-work rather than a specialized central operator. |
