emits contract event
Links a contract execution to events emitted during the call.
has function selector
Hex-encoded selector identifying the precompile function invoked.
Precompile
Entry point exposing native Hedera services (HTS, HCS) to smart contracts via reserved selectors.
has gas used
Total gas consumed by a precompile invocation.
Bhash Ontology Working Group
Vocabulary describing Hedera Smart Contract Service artefacts, execution traces, and system contract integrations.
Hedera Smart Contract Service module
Phase 3 sprint module covering smart contract deployment, execution, and HTS precompile usage for CQ-DEV-005.
System contract
Reserved contract deployed by Hedera for protocol operations such as HTS precompiles.
has contract id
Ledger identifier (e.g., 0.0.x) for a deployed contract.
Contract execution
Process representing a transaction that executes a smart contract function.
has result status
Execution status such as SUCCESS, REVERTED, or INSUFFICIENT_GAS.
has gas schedule
Associates the Smart Contract Service with the published gas fee schedule.
Contract log
Structured record describing indexed topics and data generated by a contract event.
Contract account
Account generated for a deployed smart contract to receive funds and identify executions.
targets system contract
Identifies which system contract precompile was invoked.
Smart contract
Deployed EVM bytecode managed by the Smart Contract Service with an associated contract account.
has gas limit
Maximum gas supplied to a contract execution.
Gas fee schedule
Fee schedule that defines intrinsic and surcharge gas costs for smart contract operations.
has invocation count
Number of times a contract has been executed in the sample dataset.
has bytecode
Connects a smart contract to the bytecode package it executes.
Contract event
Event emitted by a contract execution and captured in mirror node logs.
has opcode trace
Links a contract execution to the opcode trace artefact exported by mirror nodes.
invokes system contract
Indicates that a contract relies on a particular system contract during execution.
stores bytecode in
Indicates which File Service file contains the contract bytecode.
executes contract
Links a contract execution process to the contract being executed.
records log
Associates a contract event with the structured log entry captured by mirror nodes.
includes invocation
Associates a contract execution with the precompile invocations performed during the call.
Precompile invocation
Event capturing a contract execution invoking a specific system contract precompile.
Opcode trace
Detailed record of EVM opcodes executed during a contract execution.
has gas breakdown
Summary of intrinsic, opcode, and surcharge gas components for analytics.
Contract bytecode
EVM bytecode package uploaded via File Service and linked to a deployed smart contract.
Smart Contract Service
Network service that executes EVM smart contracts and exposes system contract integrations.
