The gas limit refers to the maximum limit of cost that the deployer is willing to pay.


Halving

In a Proof-of-Stake or Delegated Proof-of-Stake blockchains, usually the word mining is replaced by validating and the word miner is replaced by validator.

Public Key And Private Key
Public key is used by one’s wallet address to encrypt the data while a private key is utilized to both encrypt and decrypt. That’s why you should never share your crypto wallet’s private key to anybody, since they will be able to do anything they want (including to move funds from your wallet).

Rug Pull
