A CKB-efficient and Anti-Collision xudt Transfer Scheme on CKB L1

[matt_ckb]

could these issues be resolved by abstraction?

It sounds like this kind of system is already getting kind of complicated already, would tasking an application with structuring deposit/withdrawal proofs be reasonable?

RFC: Compact UDT Lock

RFC: Compact UDT Lock Compact UDT lock leverages Sparse Merkle Tree to reduce storage requirements for user defined tokens on CKB. As a pure lock script, compact UDT lock is compatible with both sUDT and xUDT. One CKB cell using compact UDT lock can keep UDT balances for arbitrary number of users, while remaining constant in CKB requirements for the cell. To further optimize the transfer operations, open transaction style action is introduced, so multiple transfers can be packed together as a s…
