+## Abstract
+
+This improvement implements Ethereum [MCOPY instruction](https://eips.ethereum.org/EIPS/eip-5656)
+
+## Motivation
+
+This change introduces the MCOPY instruction, an efficient instruction for copying memory areas, to Rootstock's VM. This improves compatibility with EVM opcodes.
+
+## Backward Compatibility
+
+This change is a hard fork and therefore all full nodes must be updated.
