Protocol Overview
Learn about the technical aspects of the Bridge Network.

The Bridge Network Core

The core of Bridge Network is controlled by on-chain smart contracts powering the protocol, oracles that broadcast data from one network to another and validators that authenticate transactions on the network. The network is uncontrolled and maintains security by ensuring validators run the same process upon receiving the various chains events. Only when 70% of validators have signed the same transaction with their key collectively, the network achieves consensus.

Protocol Stack

The Bridge Network protocol consists of three main layers:
  1. 1.
    Application Layer - Made up of all the cross-chain tools
    Any cross-chain tool can be built on the Bridge Network application layer and plugged into the blockchain and protocol layer. The Application layer supports different kinds of applications like the Bridge-builder, NFT bridge, cross-chain trading, Token bridge and others in the works.
  2. 2.
    Blockchain Layer - Contains all Bridge Network(BN) smart contracts for supported blockchains and oracles that act as data relayers.
  3. 3.
    Protocol Layer - Combines the blockchain layer with the validators.
    Every cross-chain transaction initiated through Bridge Network is assigned a unique identifier (hash). Bridge validators track every transaction that passes through the smart contract of the protocol and soon as the transaction achieves its entirety, each validator is required to sign by its private key a unique identifier of the transaction all while the oracle broadcast the data to different networks.

Asset Transfers

Moving an asset between blockchains is done using the lock, unlock, mint & burn mechanism. Once a user initiates a transfer request, the amount of asset is sent to a Bridge Network smart contract on the native chain where the asset is locked. The exact amount is then minted on the destination chain by another BN smart contract.
The opposite process is repeated when a user initiates a request to move an asset back to its native network. The wrapped tokens are transferred to a BN smart contract that conducts a burn of the wrapped asset. Once the burn is complete, the original tokens are unlocked from the BN smart contracts on the native chain.

Protocol Fees

For users moving assets cross-chain, they each pay a minor fee of 0.05% to execute the transfer. More than 60% of the protocol earned fees are allocated to validators that help secure the network.
For token issuers creating their own bridge, they are required to stake 500 BRG tokens. The staked tokens are then burnt monthly, making the BRG token deflationary in nature.
