A
Account State
The recorded snapshot of a specific cryptographic address on the Dime ledger, including its balance, sequential transaction nonce, and any associated contract code or storage memory.
Air-Gapped Computer
A dedicated computer physically isolated from local area networks and the public internet, used exclusively for generating private keys and signing critical transactions offline.
Attestation
A cryptographically signed vote broadcast by a validator confirming that a proposed candidate block meets all consensus rules and state transition proofs.
B
Block
A standardized data container consisting of a header (metadata, parent hash, state root, timestamp) and a batch of validated transactions committed together.
Block Explorer
A web application or desktop client that serves as a visual search engine for a blockchain ledger, allowing users to inspect transaction histories, block contents, and account parameters.
Byzantine Fault Tolerance (BFT)
The characteristic of a distributed computing system that allows it to function correctly and reach consensus even when a subset of nodes fail or transmit conflicting information.
C
Consensus Algorithm
The mathematical rules and communication protocol that independent validator nodes follow to agree on the single true state of the decentralized ledger.
Cryptographic Hash Function
A one-way mathematical function (such as SHA-256 or Blake3) that transforms any arbitrary input data into a fixed-length string of characters. It is practically impossible to reverse or engineer collisions.
F
Finality
The point at which a confirmed block is mathematically irreversible under the protocol’s consensus rules, guaranteeing that its transactions cannot be altered or reorganized.
Fork
A divergence in a blockchain’s history where two competing blocks are proposed at the same block height. Consensus fork-choice rules resolve forks by selecting the valid canonical chain.
G
Gas / Compute Units
The unit of measurement used to quantify the computational resources (CPU instructions, memory allocations, storage writes) required to execute an instruction on the network.
Gossip Protocol
A peer-to-peer communication mechanism where nodes randomly share newly received transactions and block announcements with a subset of connected neighbors, rapidly propagating data across the entire network.
H
Hierarchical Deterministic (HD) Wallet
A key management standard (BIP-32/BIP-44) where an infinite tree of private and public keypairs can be deterministically calculated from a single master seed phrase.
M
Mempool (Memory Pool)
The temporary in-memory queue on a node where unconfirmed transactions wait before being selected by a validator and packaged into a block.
Merkle Tree
A hierarchical cryptographic tree data structure where leaf nodes represent data items and parent nodes represent the hash of their children, enabling rapid, mathematically provable verification of large datasets.
N
Node
Any computer connected to the Dime peer-to-peer network running client software that verifies transactions and maintains a copy of the ledger.
Nonce (Number Used Once)
A sequentially incrementing integer assigned to each account. Nonces enforce strict transaction ordering and prevent malicious replay attacks.
P
Peer-to-Peer (P2P) Network
A decentralized network topology where computers communicate directly with one another as equals without routing messages through a central server.
Private Key
A 256-bit secret mathematical key that allows an account owner to produce digital signatures authorizing transactions. It must never be shared.
Public Key / Address
A mathematical derivative of a private key that serves as the public identifier for an account, allowing others to send data or recognize authorized signatures.
R
Recovery Phrase (Seed Phrase)
A sequence of 12 or 24 standardized words that encode master cryptographic entropy, allowing complete recovery of a hierarchical deterministic wallet.
RPC (Remote Procedure Call)
A communication protocol and API that allows client applications (such as wallets, browsers, and scripts) to query data from a Dime node daemon.
S
State Root
A single 32-byte cryptographic hash summarizing the entire global state of all accounts and contracts on the network at a specific block height.
T
Telemetry
Real-time operational metrics (such as CPU usage, peer counts, block propagation delays, and memory consumption) collected from active network nodes.
V
Validator
An active node operator authorized by the consensus mechanism to assemble pending transactions into candidate blocks and participate in consensus voting rounds.
