An account book of final entry, in which commercial transactions are recorded. In computer systems, a ledger refers to interlinked digital files that follow the same accounting principles as the manual system.
The lightning network is a Layer 2 solution, that resides on top of the Bitcoin blockchain, which enables faster transaction processing by using payment channels. A payment channel can be initiated between peers (parties) and registers all transactions between these parties without sending them all straight to the actual blockchain (off-chain transactions). When a payment channel is closed, all transactions are then settled with each other and the outcome of all transactions is transmitted to the actual blockchain, where the transactions are recorded on-chain.
The ease and speed with which an asset or security can be traded in the market without materially affecting its price.
Litecoin – LTC
Litecoin is a peer-to-peer cryptocurrency and open-source software project founded by Charlie Lee on the 7th of October 2011. It is based on the Scrypt proof-of-work network and is sometimes referred to as the silver to bitcoin’s gold. Litecoin is an early altcoin and a fork of the Bitcoin Core client, differing primarily by having a decreased block generation time of 2.5 minutes, a maximum number of 84 million coins, a different hashing algorithm (Scrypt, instead of SHA-256) and a block halving every 840,000 blocks.
