synos-hive-bft — HotStuff Byzantine-Fault-Tolerant Consensus

What It Is

synos-hive-bft is the HotStuff Byzantine-Fault-Tolerant consensus core for the Arcanum Hive. It provides distributed agreement across mesh nodes, enabling the hive to reach consensus on state changes even when some nodes are Byzantine.

Architecture

Consensus Protocol

Leader proposes block → Nodes vote → Leader collects votes → Nodes commit

Components

Component	Purpose
leader	Block proposal and vote collection
validator	Vote on proposed blocks
view	View change mechanism for leader rotation
crypto	Signature aggregation and verification

How It’s Wired

1. synos-hive-controller — uses BFT for workload orchestration decisions
2. synos-hive-profiler — consensus on node capability assessments
3. synos-audit-trail — logs all consensus events
4. synos-security-boundary — validates node eligibility for consensus

Future Ideas

1. Dynamic validator sets — add/remove validators without restart
2. Light client — efficient verification for resource-constrained nodes
3. Cross-chain bridges — consensus anchoring to external chains
4. Threshold signatures — BLS signature aggregation for efficiency
