Eminer Bi-Monthly Report（2022.12–2023.1）

Eminer Public Chain 1) Remove implicit approval chilling upon slash. 2) The JSON-RPC client no longer hangs when invalid batch results are returned by the server. 3) A corner-case issue in the filter system is resolved. 4) Various improvements to snap sync are included in this release. 5) Correctly populates rosetta’s /network/status endpoint response. Rosetta’s data api is divided into its own go files (account, block, mempool, network).

Eminer Bi-Monthly Report（2022.4–2022.5）

Eminer Public Chain 1)Research EIP-4907,an extension of ERC-721. It proposes an additional role (user) which can be granted to addresses, and a time where the role is automatically revoked (expires). 2) Based on these changes on testnets, this change should decrease Parachain block times on Testnet to a significant degree. 3) Finality notification: optimize calculation of stale heads. 4) Reduce network bandwidth, improve parablock times: optimize.
