Pump — increase in demand and price of a token. It happens most often when a token has a utility, such as when it is needed for farming, but it also happens when it is pumped on shills. Especially when the shills are shilled by cult members of the community and developers.
PoS (Proof-of-Stake) — an alternative PoW algorithm for reaching consensus when writing a block to a blockchain, where the probability of writing a new block to the blockchain and receiving a corresponding reward is proportional to the user's ownership interest in the system.
PoW (Proof-of-Work) — an algorithm for reaching consensus in the bitcoin mining network in which it is determined which of the mining nodes will write the generated block to the blockchain. 
Rewards — free tokens, which are distributed for participation in the launch of the project to the first users and provide liquidity, as a rule, they are the highest at the launch and then decrease as the number of participants increases, or stops altogether.
Scam — fraud, forgery, most often used when creating copies of existing projects, tokens, or fundraising to steal money.

State channels — a technology that allows the exchange of information (transactions) between nodes in the network, without first writing to the blockchain. The idea of state channels is to move many intermediate processes outside the blockchain while maintaining the characteristic reliability of the blockchain.
Timelock — software time limit on any actions, often imposed on users of projects with large rewards to limit dumping, or on developers to limit exit from liquidity
