Summary of the Week:

• Developed Dora Network iOS wallet functionalities, and designed cross-chain smart contract.

1) Dora Network Wallet Development

• Determined the reason for abnormal transfer issue: the bug that comes with the nodejs codebase;
• Added logic for Token Increase.

2) Dora Network Research and Development

• Implemented voting logic, including: web3 interface, transaction logic, and browser display.

3) Cross-Chain Smart Contract Design

The cross-chain smart contract deployed on the main chain is the agent of the sub-chain in the “main chain”, responsible for transferring the token assets between the main chain and the sub-chain and maintaining the information of the nodes. It’s mainly composed of the following functions:

• function submitBlock(uint256 blockhash, uint356 root, byte[] bp_update_tx, uint256 height, uint256[] signatures);
• function Deposit(address contract, uint256 amount);
• function Exit(address contract, uint256 amount);
• function Withdraw(byte[] exit_tx, uint256 height, uint256[] path_proof).
