• Halving

    The process of intermittently decreasing the block reward given to cryptocurrency miners by 50%. Halving can have long-term effects on the price of BTC.

  • Hard Cap

    The maximum amount of money a cryptocurrency’s founders will accept while raising money in exchange for early coins on their platform.

  • Hardware Wallet

    A physical device that stores private keys for cryptocurrencies.

  • Hash

    The encrypted value generated by a blockchain algorithm that does not resemble the original data related to the transaction it represents. Hashing is an essential part of confirming transactions on proof of work blockchains.

  • Hash Rate

    The number of hashes per second the Bitcoin network is performing. Considered a general measure of the processing power of the network.

  • Hashed Timelock Contracts (HTLC)

    Hashed Timelock Contracts are used to create smart contracts that enable conditional payments They require that the receiver of a Crypto payment acknowledges the receipt before a deadline, by generating cryptographic proof of payment. If proof of receipt is not sent, they forfeit the ability to claim the payment, and it's returned to the sender.

  • Hashgraph

    A consensus mechanism and distributed ledger technology that is an alternative to a blockchain. The algorithm was created by Leemon Baird, CEO of Swirlds. A hashgraph does not require miners and uses directed acyclic graphs for time-sequencing transactions, without bundling them into blocks.

  • Hashing Power

    The mining power that a device uses to run and solve hashing algorithms that generate new cryptocurrencies and validate transactions on a blockchain network. Similar in concept to a car's Horse Power.

  • Haskell

    A computer programming language used to develop some cryptocurrencies, such as Cardano.

  • Hot Wallet

    A Crypto wallet that is connected to the internet and is used to send and receive coins/tokens. Hot wallets are considered less secure than cold wallets.

  • Hybrid Consensus

    A consensus mechanism that combines elements of multiple other consensus protocols, such as Proof of Stake and Proof of Work algorithms.
