Rollup
A rollup executes transactions outside a settlement chain while publishing data or commitments that let the settlement system verify resulting state. Optimistic…

Numbers and symbols are grouped under #. Letter matching ignores case and uses the first displayed title character.
Rollup Bridge
A rollup bridge transfers assets or messages between a rollup and another chain through deposits, withdrawals, and verification contracts. Withdrawals reverse that…
Rollup Compression
Rollup compression reduces the bytes required to publish transaction or state-change data, lowering data-availability costs without changing intended execution results. Methods include…
Rollup Contract
A rollup contract is an on-chain program that records rollup commitments and enforces deposits, proofs, challenges, withdrawals, or protocol upgrades. The contract…
Rollup ID
A rollup ID is a protocol-defined identifier that distinguishes one rollup instance when routing transactions, messages, state, or configuration. The identifier may…
Rollup Sequencer
A rollup sequencer receives user transactions, chooses their order, builds rollup blocks, and submits batches or commitments for settlement. A centralized sequencer…
Rollup Stack
A rollup stack is a coordinated set of software components and specifications for launching, operating, proving, and bridging rollup chains. Stacks promote…
Rollup State Root
A rollup state root is a cryptographic commitment summarizing the rollup's account, contract, and storage state after a defined batch. The rollup…
Rollup Transaction
A rollup transaction is a user or system operation executed under a rollup's rules before its result is batched for settlement. The…
Ronin Bridge
Ronin Bridge is infrastructure for moving supported tokens and NFTs between Ronin and connected networks through designated bridge routes and contracts. The…
Rootstock Smart Bitcoin (RBTC)
Rootstock Smart Bitcoin is the native gas and value-transfer asset of Rootstock, an EVM-compatible Bitcoin sidechain that uses a two-way peg mechanism…
Rough Consensus
Rough consensus is a decision practice that advances when dominant agreement exists and substantive objections have been considered without requiring unanimity. Participants…
Routing Attack
Routing Attack is an attack or weakness pattern that manipulates or disrupts network path selection to intercept, delay, redirect, isolate, or deny…
RPC Endpoint
RPC Endpoint is a network address that accepts remote procedure calls for a blockchain node or service. It is used to let…
RPC Error
An RPC Error is a protocol, transport, provider, node, or method-level failure returned or observed when a client invokes a remote procedure.…
RPC Failover
RPC Failover switches blockchain RPC traffic from an unhealthy, slow, rate-limited, or inconsistent endpoint to an alternative endpoint. It can be automatic…
RPC Latency
RPC Latency is the elapsed time between sending a remote procedure request and receiving its response, measured at a defined observation point.…
RPC Monitoring
RPC Monitoring observes blockchain endpoint availability, latency, correctness, capacity, chain synchronization, and method behavior. It should detect both obvious outages and subtle…
RPC Node
An RPC node is a blockchain node configured to answer application requests through an RPC interface. It may be self-hosted or operated…
RPC Rate Limit
An RPC Rate Limit restricts the request count, compute units, method cost, or concurrent workload allowed against a blockchain RPC service. Limits…
RPC Retry
RPC Retry is a repeated remote procedure call after a transient failure, timeout, throttling response, or unavailable endpoint. Retry behavior must account…
RPC Subscription
RPC Subscription is a persistent or long-lived RPC registration through which a client receives notifications when selected blockchain or node conditions change.…
RPC Timeout
An RPC Timeout occurs when a blockchain RPC request does not complete within the configured connection, response, or total deadline. It can…
