Private Blockchain

Distributed Ledger Technology

Distributed Ledger Technology (DLT) refers to a decentralized digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time. Unlike traditional databases, DLTs do not rely on a central data store or administrative functionality. Instead, each node within the network processes and verifies every item, generating a record of each item and creating a consensus on its truth. This architecture provides a shared, immutable history of information across a network of participants.

Permissioned Blockchain

A blockchain network where validation, transaction submission, data access, or governance is restricted by defined permissions.

Scalability

Scalability in blockchain refers to the capacity of a distributed ledger system to process an increasing volume of transactions per second (TPS) while maintaining decentralization and security. It represents the system's ability to handle global adoption without suffering from prohibitive latency or excessive transaction fees. Achieving this often involves implementing consensus layer optimizations, layer-2 solutions like state channels or rollups, or sharding mechanisms that partition the network into smaller segments to allow parallelized processing across the entire ecosystem.

ASIC

An Application-Specific Integrated Circuit (ASIC) is a specialized hardware device engineered to perform a single computational task with maximum efficiency. In the context of blockchain, ASICs are designed exclusively for the hashing algorithms required to mine proof-of-work cryptocurrencies. Unlike general-purpose CPUs or GPUs, which process various instructions, ASICs are hard-wired for specific mathematical operations, providing orders of magnitude higher hash rates and energy efficiency for dedicated mining operations.

Account

In the context of blockchain architecture, an account is a persistent entity that holds a balance of native tokens, stores state data, and possesses an associated address derived from a public key. Unlike the UTXO model used by Bitcoin, account-based models—most notably used by Ethereum—track the current state of every participant, allowing for complex smart contract interactions. Accounts serve as the fundamental primitive for identity and value representation, enabling protocols to manage user assets and execution environments securely within the ledger.

Address

In blockchain, an address is a unique identifier derived from a public cryptographic key, acting as the destination for transactions. Similar to an IBAN in traditional banking, it allows users to receive digital assets. An address is typically a shortened hexadecimal string, generated by applying a hashing function to a public key. It functions as the public-facing identity of an account, ensuring that funds sent to it are only accessible to the entity possessing the corresponding private key.
