ZK Refactored Light Client
They are pared-down versions of full nodes and they rely on a fraction of the data to validate transactions. This is made possible by the principles of cryptographic hash functions and Merkle proofs, which allow light clients to verify the authenticity of transaction data and block headers with minimal information.
Zero-knowledge proofs (ZKPs) are a form of cryptographic protocol that allows one party, the prover, to prove to another party, the verifier, that a certain statement is true without revealing any information beyond the validity of the statement itself.
Omnichain Interoperability
Butter Omnichain Service
Butter Omnichain Service enables projects built on one chain to easily synchronize some project information to other chains, and can also call contract methods on other connected chains.
Core Functions
By specifying destination chain ID and wrapping the data with a constructed message object, your data can be sent to your destination contract with this function call safe and sound.
With the specified chain ID and a constructed recipt generated from the souce chain, Transfer In can help to check your data validity again light client and deliver it successfully.
function transferIn(
uint256 _chainId,
bytes memory _receiptProof
) external;
function transferOut(
uint256 _toChain,
bytes memory _messageData,
address _feeToken
) external payable returns(bool);Workflow
The workflow generally demostrated how a message gets verified within the Butter Omnichain Service.
Omnichain Development
Omnichain Swap
Omnichain Swap allows you to swap coins with substantially lower fees than traditional DeFi exchanges by connecting you to the best cross-chain DeFi protocols.
Omnichain GameFi
Gaming Finance refers to the gamification of financial systems to create profit through participation in play-to-earn crypto games.
Cross-chain Lending
With Butter Network, you can collateralize on Chain A, borrow on the destination chain, farm, repay, and the collateral is unlocked, skipping the four bridging and swapping fees.
