Double spending is a condition where the same value can be spent twice, revealing a flaw in the payment processing system.
Irreversible transactions are a characteristic of digital payment systems which offer trustless decentralization. The irreversibility is necessary in order to guarantee that no transaction will be undone once committed by the network.
A process or system by which multiple parties are able to reach consensus. In the context of cryptocurrencies, it's the process which allows for everyone to agree on everyone else's money balance. E.g. Bitcoin employs Nakamoto consensus via PoW mining.
Proof of Stake
Proof of Stake is a consensus mechanism in which block verifiers prove their commitment to the network by staking their coins instead of by proving they performed some work (contrast with Proof of Work).
Staking is the process by which users delegate their Proof of Stake voting rights to a staking pool. The pool then verifies transactions on the users' behalf and, similarly to mining pools, share some of the profits back with the stakers.
Litecoin is a first generation cryptocurrency which was originally forked from the Bitcoin source code. It substituted Bitcoin's SHA256 hashing algorithm for Scrypt as an attempt to make ASIC mining impossible.
A PoW based mining method by which Litecoin transactions are verified and blocks get produced.
First Generation Cryptocurrencies
The first generation cryptocurrencies was spawned by Bitcoin. Several Bitcoin forks exist on this generation. Most 1st generation coins simply copied the Bitcoin source code while modifying the encryption algorithms and total coin supply.
Second Generation Cryptocurrencies
The second generation of cryptocurrencies added on-chain smart contracts and fully featured contract programming languages. Ethereum, which is the most notable 2nd generation cryptocurrency, brought smart contracts and introduced tokens to the masses, spawning the wave of ICO's from 2014 onwards.
