Architecture overview

As a sidechain to the Ethereum blockchain, the Shibarium network acts as a solution to its throughput and speed issues, by inheriting the L1's security and separating the consensus and block production into two different layers. Here is a breakdown of how the Shibarium Network works:

  • Ethereum layer, where a collection of core contracts on the Ethereum mainnet handles the staking of the Bone token, among other features.
  • Heimdall layer, where a set of proof-of-stake Heimdall nodes run alongside the Ethereum mainnet.
  • Bor layer, where a set of Bor nodes are responsible for block production.

Ethereum smart contracts

A series of staking management contracts live on the Ethereum mainnet. They allow anyone to stake Bone tokens on the Ethereum mainnet staking contracts and become a validator in the system. It is also possible to earn staking rewards for validating state transitions on the Shibarium Network.

Heimdall, the validation layer

The Heimdall layer manages the aggregation of blocks produced by Bor into checkpoints and periodically publishes it to the Ethereum mainnet. Validators verify all blocks since the last checkpoint, create a Merkle tree of block hashes and publish its root hash on the Ethereum mainnet.

Bor, the block producer layer

Bor is Shibarium's sidechain block producer, responsible for executing transactions and aggregating them into blocks. Bor block producers, a subset of validators, are periodically shuffled by Heimdall validators.
