Kernel:
1.Added the create wallet API
2. Blockcenter added database connection pool, CRUD of individual tables, and increased database mock unit tests.
3. Added API clients that query blocks from all nodes.
4. Designed the wallet recovery plan through mnemonic word.
Blockexplorer
1, Bytom explore v2 version API launched blockmeta.com/api/v2/
2. The bytom explore API document has been updated to version v2
3. Completed the explorer common data component
Contract
1. Optimized the index statistics of the hash type detection, value detection, and lock/unlock statement of the if-else statement in the equity compiler
Wallet
1. Transaction page：Reconstruct the details of a transaction to summarize the deposit,withdraw and assets of a transaction.
2. Transaction page：Added a display of transaction status.
3. Front-end basic tools, cli packaging, deployment, local debugging

3. Redemption transaction test on the side chain
4. The side chain transaction was packaged to generate block tests
National encryption algorithm:
1. Modified the bug of error check in SM2 algorithm signature.
2. Modified the AES symmetric encryption algorithm to the SM4 National encryption algorithm, and completed related testing work.
3. Sorted out technical documents of Bytom network.
