可以看一下 Open Tx 系列，通过 Open Transaction 可以实现。

Open Tx Protocol Brainstorm: (1) OTX in General

Background Open Transaction (OTX) is a deliberately constructed portion of transaction, which can be combined together to form a valid transaction. It is not a simple slice of a valid transaction. Firstly, OTXs are signed by participants to restrict the final transaction to their intentions, like predefined output amount, receiver address, and so on. Sencondly, one OTX can be freely combined with other OTXs as long as the combined TX follows the constraints defined by the OTXs. OTX is important…

Open Tx Protocol Brainstorm: (2) Design a Practical Protocol on CKB

Motivation To design a protocol for Open Tx, we need to follow some basic principles, such as signature rules, combination rules and security concerns. In this post, I wanna talk about these issues. Signature rules In general, every meaningful lock script needs an asymmetric cryptographical signature to unlock. For default SIGHASH_ALL scheme, it first calculates the full TX’s hash, then sign the hash result. For OTX, to confirm the ownership, it’s signature must cover every OTX’s inputs and the…

Open Tx Protocol Brainstorm: (3) Scenarios Analyzing on CKB

OTX Scenarios on Nervos CKB I believe that the first step to design a protocol should be thinking about the scenarios where it will be used. Nervos CKB is the security anchor of a layered system, it supports UTXO like transaction structure and Turing complete VM through lock script and type script. This transaction schema is much more complex than Ethereum, but it also enables more possibilities. Here I list some possible scenarios that may need open transaction technology. Thanks to the advanc…
