Honest-Majority Hashpower Assumption
Bitcoin assumes a majority of effective hashpower follows consensus-valid chain extension over time.
Type: economic
Severity: critical
Research
Security Assumptions
Filters
Network Propagation Assumption
Security and usability assume blocks and transactions propagate across peers quickly enough to limit stale/fork windows.
Type: network
Severity: high
Economic Incentives Assumption
Bitcoin assumes most participants prefer strategies that preserve long-term network value over short-term destructive behavior.
Type: game-theory
Severity: high
Cryptographic Assumption
Bitcoin security assumes practical resistance of SHA-256 hashing and signature schemes against forgery and collision attacks.
Type: cryptographic
Severity: critical
