server maintained by its owner, somewhat like full nodes, but with additional
functionalities such as anonymizing transactions, clearing transactions, and
participating in governance and voting. It was initially popularized by Dash to
reward owners of these servers for maintaining a service for the blockchain.
Max Supply: The best
approximation of the maximum amount of coins that will ever exist in the
lifetime of the cryptocurrency.
MCAP: Short for market

Miner: A group of
computers that add new transactions to blocks and verify blocks created by
other miners. Miners collect transaction fees and are rewarded with new
bitcoins for their services. Mining is a zero sum game and the winner takes
all.
Multi-Sig: Multi-signature

number of applications.
Mempool: A mempool (a

storing information on unconfirmed transactions. It acts as a sort of waiting
room for transactions that have not yet been included in a block.
Merkle Tree: A tree structure
in cryptography, in which every leaf node is labelled with the hash of a data
block and every non-leaf node is labelled with the cryptographic hash of the
labels of its child nodes. Hash trees allow efficient and secure verification
of the contents of blockchains, as each change propagates upwards so
verification can be done by simply looking at the top hash.
MetaMask: An online digital
wallet that allows users to manage, transfer and receive Ethereum, operating as

cryptocurrencies have a system through which miners can be rewarded with
newly-created cryptocurrencies for creating blocks through contributing their
hash power. Cryptocurrencies with this ability to generate new cryptocurrencies
through the process of confirmation is said to be mineable. * Not Mineable Some
cryptocurrencies are generated only through other mechanisms, such as annual
inflation through staking. These cryptocurrencies are said to be not mineable.
Mining: A process where

process through which new bitcoin or some altcoins are created.
Mining Contract: Another term for
cloud mining, where users can rent or invest in mining capacity online.
Mining Difficulty: The mining
difficulty of a cryptocurrency is how difficult it is to find the right hash
for the next block.
Mining Farm: A mining farm is
when a group of miners mine together for a variety of advantageous reasons,
like energy use.
Mining Pool: An arrangement
where a number of miners pool their resources to increase their chances of
finding the next block.
Mining Reward: The income that
miners receive after finding and validating a block.
Mining Rewards: Mining rewards are
the rewards that crypto miners receive for mining a new block on the
blockchain.
Mining Rig: Equipment that is
used for mining cryptocurrencies.
Mt. Gox: Bitcoin’s first
major exchange. It was shut down in February 2004 after losing around 850,000
