📄️ CoTA Protocol Overview
The CoTA (aka. Compact Token Aggregator) protocol is a layer-1.5 account based fungible / non-fungible token and k-v data managment solution on Nervos CKB. The basic idea of CoTA is to manage and verify enormous number of data by a Sparse Merkle Tree (SMT) with a constant size of on-chain storage space, like 32bytes. The draft version of the CoTA protocol was published on Nervos Talk at 2021. Since then, the CoTA protocol has evolved rapidly and extended to more user scenarios, including unique CCID, 3rd-party data storage, JoyID, etc.
