• Machine Learning (ML)

    An application of artificial intelligence (AI) that enables systems to automatically learn and improve from experience without being explicitly programmed. ML programs access data and learn patterns and make inferences.

  • Mainnet

    The main version of a blocckhain protocol that uses currency with real world value to transact. Most Crypto projects test and demonstrate the capabilities of their projects to investors and users in a safe environment called a “testnet.” A cryptocurrency is generally considered to be “live” after the first Mainnet block is mined.

    Also known as micropayments, microtransactions are very small payment that are commonly used in blockchain-based content management and gaming projects.

  • Mining

    The process of adding transaction records (blocks) to a blockchain's ledger of past transactions. Miners confirm transactions and help maintain the network in exchange for block rewards.

  • Mining Pool

    A group of cryptocurrency miners that combine their computational resources over a network to increase their collective mining power. They split rewards evenly based on each person's mining contributions.

  • Mining Rig

    A computer used for mining cryptocurrencies. A rig can be a dedicated computer built and operated specifically for mining or it could also be used for other purposes.

  • Minting

    The process by which new coins are created on a Proof of Stake (PoS) blockchain to reward miners for verifying transactions and creating a new block.

  • Multi-Layer Blockchain

    A blockchain network that uses a multilayered architecture to address technical problems related to low transaction rates and scalability. Multilayered blockchains often devote one layer to data storage, and a secondary layer to confirming transactions and other purposes.

  • Multisig

    Abbreviation for multi-signature. A feature that requires several keys to authorize a single transaction. Multisig wallets and other tools are used to avoid a single point of failure and for dividing responsibility among separate parties.

  • MyEtherWallet
