(Compared with zion, the new types: mint_nft, withdraw_nft, swap and change pubkey can be authorized by onchain functions, and support eip-1271 sig) The test investigated halo2 related codes (fibonacci circuit), pse version ipa -> kzg (on-chain verification) Refactor the recursive circuit part, pass the basic process test and benchmark. (setup and vk create: 886s, proof for aggregate(proof num:2, depth:3): 1374s) ZkRollup core/txpool: allow future local transactions fix ws test timeout and other bugs consensus: improve consensus engine definition nit: int->uint64 in GetTxReceipt Cortex investigates Ledger hard wallet signatures and develops adaptationsCommunity Updates👨‍👩‍👦‍👦Cortex connects with NFT artists for joint creation and other matters;Cortex NFT Gallery tutorial edit:Cortex NFT community planning;Continue to monitor popular market ventures and examine project logic and Web3, NFT & Defi Tokenomic models ## Publication Information - [Cortex Labs](https://paragraph.com/@cortex-labs/): Publication homepage - [All Posts](https://paragraph.com/@cortex-labs/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@cortex-labs): Subscribe to updates - [Twitter](https://twitter.com/CTXCBlockchain): Follow on Twitter
