Multichain Middleware

What does Multichain Middleware mean?

The Balance is the multichain platform providing bridges connecting external public blockchains. Therefore, building DApp on The Balance makes it easy to manage assets by connecting to Layer 1 mainchains such as Ethereum and Solana or Layer2 networks such as Polygon. Service providers can efficiently implement interoperability using multichain bridge interworking of The Balance and move selective assets according to characteristics of the data. As The Balance's bridges support standardized interworking interfaces based on Rosetta open source, it is expected that they will be able to connect with most major Layer 1 networks in the future.

Improved Bridge Protocol

Cross-chain/multichain bridges are channels connecting sidechains to the public blockchain ecosystem and the real economy, so they mediate the value movement of assets between two networks. For this reason, they are significant in the entire blockchain ecosystem. However, it is challenging to ensure on-chain-level reliability. Because it is usually implemented as off-chain services based on relay nodes and is vulnerable to exploits on security, these have been raised as ongoing market issues.
The Balance Bridge verifies all transactions in the Multi-sig method using a delegation that borrows the rights of validators participating in the network. The Balance has enhanced reliability and minimized the possibility of attacks through single node hacking by introducing Multi-sig verification implemented with the validator's authority delegation. Also, it improves the protocol to relay both network chains by applying MPA(Multi-Part Authorization) method, enabling secure data processing from the threat of forgery.

Trusted Relaying Environment

Relay nodes of The Balance Bridge relaying multichain are operated in trusted serverless environments, isolated from the existing operating environments. This prevents relay cessations and Multi-sig delays due to unstable execution environments and protects bridges from exploits through node access.
