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Cooldown Period : 7-day waiting period after initiating unstaking before tokens can be withdrawn.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