Kademlia routing is a routing mechanism used to carry out cross-shard messages in the Harmony blockchain's adaptive state sharding system. Information about all the Harmony network nodes across different shards is stored in a routing table. By using Kademlia-based routing, messages between nodes on different shards travel much faster than normal gossip broadcasting to reach the destination shard. Through this process, the Kademlia routing mechanism significantly reduces the overall network load, resulting in a blockchain that is quite efficient at carrying out cross-shard messaging.

Keep Network provides a privacy layer for public blockchains that enables users and apps to privately transfer and store data in off-chain containers called 'keeps.' KEEP is the network's native token. Participants can earn fees denominated in KEEP for participating in the maintenance of keep containers.

KEEP is the native token of the Keep Network, a protocol that allows public blockchain users and apps to privately transfer and store data in off-chain containers called 'keeps.' Users can stake KEEP tokens to be randomly selected to earn fees by performing services on the network such as encryption or data storage.

Keosd is a key manager daemon used within the EOSIO blockchain system for storing private keys and signing digital messages.

The most important part of an operating system (OS), the kernel controls most of the components and functions of a computer, smartphone, or related hardware device. Every OS has a kernel inside it that connects the hardware to the software and processes of the device. The kernel determines how the central processing unit (CPU) operates, monitors and manages storage memory, handles software requests, and handles other key functions and tasks necessary for a device to function optimally and reliably.

A cryptographic key is a string of bits that is used by an encryption algorithm to convert encrypted ciphertext into plaintext and vice versa as part of a paired key access mechanism. Keys are usually randomly generated and, unlike a password, are not intended to be memorized by users.

A keylogger is a software program that copies or records the keystrokes that a user inputs through a keyboard to a mobile device, computer, or related system. Keyloggers are typically employed with the intent of stealing sensitive information such as passwords, pin numbers, or other confidential data — often with the intent of financial gain, or to steal personal information needed to hack into a website, bank account, crypto wallet, computer network, or hardware or software system.

The Key Management Interoperability Protocol (KMIP) facilitates the exchange of data between cryptographic key management servers and clients. It plays a key connective role in the function of crypto wallets and other decentralized products. KMIP was established by the Organization for the Advancement of Structured Information Standards (OASIS), a non-profit consortium focused on the development and adoption of open, global information-sharing standards.

Know Your Customer (KYC) is the compliance process instituted by regulators for businesses to verify the identity and level of risk of their customers. This process normally requires users to provide official identity verification using a passport, driver’s license, or similar documents. KYC regulation requires financial firms to collect personal data on their customers and ensure the legitimacy of the person or client to whom they may provide services.

Kraken is a major U.S. crypto exchange founded by CEO Jesse Powell in 2011. It offers derivatives trading, spot trading, and other related services.

The Kyber Network is a blockchain protocol that aggregates token liquidity from across the Ethereum ecosystem and facilitates the exchange of tokens without an intermediary.
