v5.0 activation
One potential complication we probably need to deal with and think about. Interpretation of ErgoTree must depend on the version number stored in ErgoTree.header. Regardless of the current blockVersion, the semantics (and hence interpretation) of a contract is defined by ErgoTree.version. We currently have ErgoTrees with versions 0 (v3.x releases) and 1 (v4.x) in their headers. After v5.0 is activated, version 2 will also be allowed. Thus, after v5.0 activation we will have blocks with increased version, but most of the transactions will spend boxes with 0 and 1 in ErgoTree.header.
With this in mind the current condition
In principle it can be replaced with
