Bitcoin, ethereum, altcoin crypto dictionary!

Signature – The mathematical sequence created by concatenating the private and public keys that proves that the bitcoin transaction originated from the given address.

ASIC (Application Specific Integrated Circuit) – These single-task silicon chips solve SHA-256 hash problems, approve transactions and mine new coins.

ASIC miner – Hardware that contains an ASIC chip and is specifically designed for bitcoin mining. These devices connect directly to a computer or network using an ethernet cable or wireless connection.

Transfer – Electronic transfer of funds between two people. Transfer is often used to send and retrieve traditional (fiat) currency from bitcoin-based exchanges.

Mining – Cryptocurrency mining uses our computer’s hardware to perform cryptographic mathematical operations, thereby creating new cryptocurrencies.
