Upload Data to the Blockchain

The bitcoin blockchain is a timestamp server. That means it can proof that certain documents were added to the blockchain at exactly that time and not modified later, which led to a variety of applications within the BSV space. From certifying documents against the blockchain to later proof no modification of it occurred to social media posts. While miners are not required to keep a copy of your blockchain post for all eternity on their mining servers, a whole ecosystem spawned over the years that uses the blockchain as decentralized storage system.

OP_Return data on the blockchain can be pruned by individual miners since OP_return transactions can't create another transaction (thus irrelevant for the validation process).

Even though the hosting of uploaded data is not guaranteed, the hash of transactions is always verifiable via SPV networks and presents a long term reliable path to verify that B://cat data is unaltered since upload.

The business of maintaining and hosting OP_Return data onchain has found some traction with services such as Project Babbage, Metashard and Planaria.
