This release delivers the new implementation of ErgoTree interpreter with Just-in-Time (JIT) costing.
In this release both v4.x and v5.0 interpreters are implemented side-by-side. The old interpreter (v4.x) is used before version 3 of Ergo Protocol is activated after that the new interpreter (v5.0) is used.
This switch happens automatically based on activated protocol version passed in context parameters.

Summary of changes

  • AOT costing of ErgoTree has been replaced by JIT costing
  • introduced new AOT costing of signature verification
  • fixed bugs in xorOf global operation, CONTEXT.selfBoxIndex, Coll.append (++ operation), Coll.zip, substConstants
  • removed limitations on lambda argument of Coll.flatMap
  • significant performance optimizations (2-3x) of contracts evaluation
  • reduced memory footprint of interpreter
  • code cleanups and documentation
