Ethereum has entered the post-merger era, how much do you know about Ethereum 2.0? This article takes you through it with 15 concepts.
1. Beacon chain
The beacon chain introduces proof-of-stake to Ethereum 1.0, running in parallel with Ethereum 1.0. The beacon chain is also known as the coordination layer.
The beacon chain has the following functions:
-
Assign validator responsibilities
-
confirm checkpoint
-
Implements a protocol-level random number generator (RNG)
-
Facilitate the operation of the beacon chain
-
Vote to determine the head of the forked chain
2、Slots
32 Slot = 1 Epoch
The time of 1 slot is 12 seconds, and a randomly selected validator proposes a block within this time. There may or may not be blocks in each slot. All validators are divided into committees, with one or more individual committees responsible for validating each slot. One validator in the committee will be elected as an aggregator (aggregator), while the other 127 validators will do the validation. After each epoch, validators from various committees are mixed and merged into new committees. Each committee has at least 128 validators.
3、Epoch
1 Epoch = 32 Slot
1 Epoch represents the number of 32 slots, which takes about 6.4 minutes.
Epoch plays an important role when it comes to validator queues and finality.
4. Deposit contract
The deposit contract is the gateway to Ethereum 2.0 via smart contracts on Ethereum 1.0.
The smart contract accepts any transaction with a minimum of 1 ETH and valid input data.
The Ethereum 2.0 beacon node listens to the deposit contract and uses the input data to trust each validator node.
5. Input data
Input data, also known as deposit data, is a user-generated sequence of 842 characters in length.
It represents the verifier public key and withdrawal public key, signed by the verifier private key. Input data needs to be added to the transaction and deposit contracts in order to be recognized by the beacon chain.
