Blockchain

Coin burning is the deliberate and irreversible removal of part of the tokens from circulation. The mechanism reduces the supply of the asset and is often used to manage the issuance of a cryptocurrency.

Scrypt is a hashing algorithm underlying a number of cryptocurrencies. It was created to be more memory-intensive and was originally designed to resist specialized hardware.

Compilation issues are errors in converting a smart contract's source code into an executable form. Because of them a crypto exchange may reject a token when a listing application is submitted if the code fails verification.

A stale block is a block or unit of a miner's work that has lost relevance because the network or pool has already accepted another result. Such work brings no reward.

A public key is the open part of a cryptographic key pair that can be freely shared. A receiving address for cryptocurrency is formed on its basis.

A mining pool is an association of miners who jointly search for a new block and split the reward in proportion to the power they contribute. This increases the chances of a stable income.

A dust transaction is a transfer of an extremely small amount of cryptocurrency, almost devoid of financial value. Such tiny amounts clutter the blockchain and can be used for deanonymization.

Data partitioning, or sharding, is a way of scaling a blockchain in which the network is divided into segments (shards), and nodes store and process only part of the data, increasing overall throughput.

Pending is the status of a payment or transaction that has been sent but not yet confirmed by the network or the payment system. The funds are, as it were, stuck in an intermediate state and awaiting a final decision.

Peer-to-peer (P2P, "equal to equal") is a model of decentralized interaction in which network participants exchange data and value directly, without a mandatory intermediary.
