CoTA Protocol

Wang presented the Compact Token Aggregation (CoTA) Protocol, which was developed for the CKB Layer 1 blockchain. It simplified the user experience by consolidating various tokens into a single structure, including NFTs and fungible tokens. CoTA employed a Sparse Merkle Tree (SMT) to store user data efficiently, providing essential proof of data existence and non-existence. The protocol introduced a two-step payment process, separating token balance management into distinct steps to improve transaction efficiency and security. This design allowed for fixed CKB capacity usage regardless of the number of tokens held, enhancing scalability and reducing costs. ^[4]

JoyID Devtools

Wang provided a tutorial and overview of JoyID devtools for the Nervos Network, detailing its Layer 1 (Nervos CKB) and Layer 2 (Axon) structures. Nervos CKB used Proof of Work, a RISC-V VM, and CKBytes for data storage, while Axon offered EVM compatibility and native interoperability. JoyID was described as a decentralized, non-custodial Web3 account system that eliminated the need for passwords and mnemonics, using biometrics for authentication. Developers were shown how to integrate JoyID into their dapps, enabling seamless creation and interaction with Web3 accounts on both Layer 1 and Layer 2. The tutorial included practical steps for connecting wallets, signing messages, and sending transactions using JoyID. ^[5]
