CKB Tokenomics in practice
Cheque cells improve the usability of custom tokens on CKB!
The cell is the most basic unit of CKB and is needed to contain any user-defined asset. Any Cell that is issued according to the “simple user-defined token” (SUDT) standard must be at least 142 CKBytes in capacity.
When we think about the situation of a user depositing tokens into an exchange, a question arises: who will provide the 142 CKBytes necessary to store the SUDT tokens when they are out of the user's possession?
If an exchange is required to, this would create quite a burden across a large user base, and additionally would require a user wait for a cell to be prepared before they can deposit their tokens.
To resolve this issue, the design for a "Promisory Cell" was proposed. This cell temporarily locks the user's SUDT assets and allows a specified receiver (in this case an exchange) to unlock them as long as they return the 142 CKBytes used to create the cell back to their owner.
We are glad to see innovation improving the usability of CKB’s unique design in practice! To learn more about the cheque cell, please check out this Nervos Talk post.
Nervos applies the RFC (Request for Comments) process for implementing every building block of the protocol. There were 27 Previous RFCs, which can be found here.
