Title: Where does the 40Byte OP_RETURN Restriction Exist in the Code? Post by: SilentCicer0 on November 08, 2014, 05:48:11 PM Where in the Bitcoin wallet code is the 40byte restriction for OP_RETURN transactions enforced?
So far, I've found material in the code on lines: 328 **src/script/script.h , 678 **src/main.cpp , 57 **src/script/standard.cpp Is the 40byte restriction enforced in the code, or is there something I'm missing here? ... Answered my own question again... I think I found it here: https://github.com/bitcoin/bitcoin/pull/3737/files For anyone else who wants to read about OP_RETURN, this post was pretty sweet: http://bitcoin.stackexchange.com/questions/29554/explanation-of-what-an-op-return-transaction-looks-like Cheers, SC.
