This page describes terms you may encounter when working with Blockchain Analytics.
To filter this page, do one or more of the following: select a category, type a search term, or click a column heading to sort.
| Category | Term | Definition |
|---|---|---|
| Blockchain technology | block reward | A block reward is a cryptocurrency reward given to miners or validators for their work on a blockchain. |
| Blockchain technology | blockchain | A distributed ledger that records all transactions that have ever taken place on the network. The blockchain is comprised of consecutive groups of transactions, known as blocks. |
| Blockchain technology | consensus mechanism | A way for nodes on the blockchain network to agree on the state of the blockchain. Proof-of-Work (PoW) and Proof-of-Stake (PoS) are two commonly used consensus mechanisms. |
| Blockchain technology | node | A computer that maintains a copy of the blockchain ledger and participates in the network by validating transactions and adding new blocks to the chain. Nodes are essential for the security and decentralization of blockchain networks, as they help to prevent malicious actors from tampering with the ledger. |
| Data processing | derived data | Processed data that provides value beyond raw on-chain data, e.g. contract labeling, token balances, etc. |
| Data processing | raw data | On-chain data with minimal data processing. |

account | An account is a unique identifier on the blockchain that can hold ether and interact with smart contracts. There are two types of accounts: Externally Owned Accounts (EOAs) and Contract Accounts. EOAs are controlled by private keys. Contract accounts are controlled by code. |
| Ethereum | ether (ETH) | Ether is the native cryptocurrency of the Ethereum blockchain. It is used to pay for gas, which is the computational resource required to execute transactions and smart contracts on the Ethereum network. Wei is the smallest denomination of ether. One ether is equal to 10^18 wei. |
| Ethereum | EVM | The Ethereum Virtual Machine (EVM) is a software program that runs on every node on the Ethereum network. The EVM is responsible for executing transactions and smart contracts. |

finality | Finality is a guarantee that a block cannot be altered or removed from the blockchain without a significant group of validators losing their staked cryptocurrency. Finality can be denoted by commitment level or block tag. |

gas | Gas is a unit of measurement that is used to quantify the computational resources required to execute a transaction or smart contract on the blockchain network. This transaction is paid on the native token for the network. |

log | Logs are records of events that occur on the blockchain. They are created by smart contracts when they execute certain functions. Logs can be used to track the activity of smart contracts and to get information about the events that have occurred on the blockchain. |

smart contract | A smart contract is a self-executing contract that is stored on the blockchain. Smart contracts can be used to automate a variety of tasks, such as financial transactions, voting, and state management. |

trace | A trace is a record of the execution of a transaction. It contains information about the steps that were taken to execute the transaction, such as the bytecode that was executed, the values of the variables, and the gas used. |

transaction | A transaction is a message that is sent from one account to another on the blockchain network. Transactions can be used to transfer cryptocurrency, create smart contracts, or interact with other decentralized applications. |
| Ethereum | transaction receipt | A record of the outcome of a transaction. It contains information about the transaction, such as the block number it was included in, the gas used, and the status of the transaction (whether it succeeded or failed). |
| Numeric precision | lossless value | A decimal number represented as a STRING to preserve full numeric
precision of UINT256 decimal numbers, e.g. 42.9999999.
|
| Numeric precision | lossy value | A decimal number represented as a BIGNUMERIC to preserve numeric
precision up to UINT128, e.g. 42.9999. |
| Tron | TRX | TRX is the native cryptocurrency of the Tron blockchain. It is used to pay for gas, which is the computational resource required to execute transactions and smart contracts on the Tron network. Wei is the smallest denomination of TRX. One TRX is equal to 10^18 wei. |
| Optimism | OP | OP is the native cryptocurrency of the Optimism blockchain. It is used to pay for gas, which is the computational resource required to execute transactions and smart contracts on the Optimism network. Wei is the smallest denomination of OP. One OP is equal to 10^18 wei. |
| Fantom | FTM | FTM is the native cryptocurrency of the Fantom blockchain. It is used to pay for gas, which is the computational resource required to execute transactions and smart contracts on the Fantom network. Wei is the smallest denomination of FTM. One FTM is equal to 10^18 wei. |
| Avalanche | AVAX | AVAX is the native cryptocurrency of the Avalanche blockchain. It is used to pay for gas, which is the computational resource required to execute transactions and smart contracts on the Avalanche network. Wei is the smallest denomination of AVAX. One AVAX is equal to 10^18 wei. |
