Hello everyone,
#TVM brings several new features with the upgrade of Odyssey-3.6.6 and the No.29 voting request(approval No.32). Compiler v0.5.9 is published at the same time, to support these 3 features:
1. Opcode ‘address.isContract’: judging whether a specific address is a contract address.
2. Pre-compiled contract ‘batchvalidatesign’: processing validation for batch signs. This improves the efficiency of signature validation, as supports validating batch signatures for a specific transaction.
3. Pre-compiled contract ‘validatemultisign’: supporting validation for multi-signature.
Please use v0.5.9 compiler for your solidity code to ensure new features perform normally.(github.com/tronprotocol/s…)
Any doubt please refer to example: github.com/tronprotocol/t…
