At the end of each "epoch" (32 block slots, each slot lasting 12 seconds), each validator is pseudorandomly assigned to one of the slots of the epoch after the next, either as the block proposer or as an attester. During a slot, the block proposer uses their mempool to ...
Since validators do not need to spend a considerable amount of computing power (and thus money) on the process, they are prone to the Nothing-at-Stake attack: the participation in a successful validation increases the validator's earnings, so there is a built-in incentive for the validators to accept all chain forks submitted to them, thus ...

The solutions are then used to validate transactions, add blocks and generate new bitcoins. Miners are rewarded for solving these puzzles and successfully adding new blocks. However, the bitcoin-style mining process is very energy intensive because the proof of work is shaped like a lottery mechanism.
The network nodes fetch, validate, and deliver data from multiple sources onto blockchains to execute smart contracts. [11] In addition to the transfer of external information to a blockchain, Chainlink can also be used for several different off-chain computation functions, including a verifiable random function (VRF) and data feeds. The data ...
