Glossary

Key terms and definitions.


A-D

Archive Node : Node specialization optimized for historical data storage and queries.

Batch Settlement : Process of aggregating micro-rewards and settling them on-chain every 5 minutes.

Cache Optimizer : Node specialization using predictive caching for high hit rates.

Cooldown Period : 7-day waiting period after initiating unstaking before tokens can be withdrawn.

DuckDB : Embedded analytical database used for local query execution on each node.


E-H

Economic Decentralization : Decentralization through multiple independent operators making independent economic decisions, rather than just geographic distribution.

Gossip Protocol : Peer-to-peer communication protocol for state synchronization and failure detection.

Hash Ring : Consistent hashing structure used to distribute data across nodes.


I-N

Node : A server running StreamSync software that serves queries and participates in the network.

Node Specialization : One of four node types (Speed Runner, Cache Optimizer, Archive Node, Reconstruction Spec) optimized for different workloads.


O-R

Query Racing : Competition where 3-5 nodes race to answer each query, with the fastest correct response winning.

Reconstruction Specialist : Node specialization capable of reconstructing compressed accounts using ZK proofs.

Reputation Score : Metric combining performance, accuracy, and uptime history that affects node selection probability.


S-Z

SLA (Service Level Agreement) : Performance guarantee (e.g., sub-10ms latency). Missed SLAs result in automatic refunds.

Slashing : Penalty mechanism that removes a portion of a node's stake for misbehavior.

Speed Runner : Node specialization optimized for lowest latency queries.

Stake : STRM tokens locked by node operators as collateral and to earn query routing priority.

STRM : Native utility token of the StreamSync network, used for payments, staking, and governance.

Treasury : Protocol fund receiving 20% of query fees, controlled by governance.

Verifier : Node that confirms the correctness of a race winner's response, earning 15% of the query fee.

ZK Reconstruction : Process of reconstructing compressed Solana accounts using zero-knowledge proofs.
