This is just the latest update by Money Button in its continued support for on-chai data. In January, Money Button became the first wallet to support larger OP_RETURN data sizes of up to 100 KB. This made it possible to possible to store video, audio and image files as well as any other type of data on the BSV blockchain in a single transaction. The wallet’s creator, Ryan X Charles, was crucial in creating the first 128 MB-sized blocks.
OP_RETURN is the simplest mechanism for creating an unspendable output and carrying data within a Bitcoin transaction. However, in the original Bitcoin source code, OP_RETURN didn’t invalidate a transaction. Instead, it invalidated the output based on whether the return value was true or false. This was later changed by Satoshi Nakamoto to deter malicious behavior.
However, the new Bitcoin SV node software has restored the original purpose of OP_RETURN by ‘enabling a new standard output type forwards-compatible with the full original functionality of OP_RETURN.’
Money Button has enabled the new standard type, the wallet revealed. Scripts starting with OP_FALSE OP_RETURN will be considered standard and will broadcast with Money Button.
The new output is considered safe for a number of reasons, the first of which is that it will be the output type that all data applications will support in the future.
