Proof workflow:

Users stake money(ETH) to become a validator.
Validators are chosen at random to create blocks and are responsible for checking and confirming blocks they don’t create.

user’s stake is also used as a way to incentivise good validator behavior. For example, a user can lose a portion of their stake for things like going offline (failing to validate) or their entire stake for deliberate collusion.
If you attest to malicious blocks, you lose your stake.

Ethereum: Shard chains

tags: Ethereum,Proof-of-stake source: https://ethereum.org/en/eth2/shard-chains/ Sharding is the process of splitting a database horizontally to spread the load – it’s a common concept in computer science. In an Ethereum context, sharding will reduce network congestion and increase transactions per second by creating new chains, known as “shards”. This is important for reasons other than scalability.

Ethereum: The Beacon Chain

tags: Ethereum,Proof-of-stake source: https://ethereum.org/en/eth2/beacon-chain/ Extra coordination for the Ethereum: Shard chains. The beacon chain receives state information from shards and makes it available for other shards, allowing the network to stay in sync. The beacon chain will also manage the validators from registering their stake deposits to issuing their rewards and penalties.

How does Ethereum's proof-of-stake work?

tags: Ethereum,Proof-of-stake source: https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/#how-does-pos-work When you submit a transaction on a shard, a validator will be responsible for adding your transaction to a shard block. Validators are algorithmically chosen by Ethereum: The Beacon Chain to propose new blocks. Attestation If a validator isn’t chosen to propose a new shard block, they’ll have to attest to another validator’s proposal and confirm that everything looks as it should. It’s the attestation that is recorded in the beacon chain rather than the transaction itself....

Proof-of-history

tags: Blockchain Proof,Solana,Proof-of-stake Solana is a Proof of Stake network. This short phrase - “Proof of Stake” - represents a much larger concept with considerable complexity behind it, and even more so for Solana, which adds the unique properties of Proof of History to the mix to enable fast, low-latency transactions while still maintaining censorship resistance.
