Testnet似乎不支持带有SignatureConstraint的Corda4

问题描述

我使用SignatureConstraint构建Corda4，并使用Testnet进行部署.然后，当我进行交易时，我得到了这个异常

I build Corda4 with SignatureConstraint and deploy with Testnet. Then when I make transaction I got this exception

net.corda.core.node.ZoneVersionTooLowException: Signature constraints requires all nodes on the Corda compatibility zone to be running at least platform version 4. The current zone is only enforcing a minimum platform version of 1. Please contact your zone operator.

这是否意味着Testnet不支持签名约束?

Is this mean Testnet not support Signature constraint right?

推荐答案

Corda Testnet目前是最低平台版本1.我们将适时推出一个新的Testnet，其最低平台版本为4，该版本将支持Corda V4，从而支持签名限制.

The Corda Testnet is minimum platform version 1 at this time. There is a new Testnet with a minimum platform version of 4 coming out in due course that will support Corda V4 and therefore signature constraints.
