Abstract

The Bitcoin protocol allows to save arbitrary data on the blockchain through a special instruction of the scripting language, called OP_RETURN. A growing number of protocols exploit this feature to extend the range of applications of the Bitcoin blockchain beyond transfer of currency. A point of debate in the Bitcoin community is whether loading data through OP_RETURN can negatively affect the performance of the Bitcoin network with respect to its primary goal. This paper is an empirical study of the usage of OP_RETURN over the years. We identify several protocols based on OP_RETURN, which we classify by their application domain. We measure the evolution in time of the usage of each protocol, the distribution of OP_RETURN transactions by application domain, and their space consumption.

Regarding the use of OP_RETURN, the release notes of Bitcoin Core version 0.9.0 state that: “This change is not an endorsement of storing data in the blockchain.” At the same time, some Bitcoin explorers, (e.g. blockchain.info, blockexplorer.com, smartbit.com) allow to inspect data encoded in OP_RETURN scripts.

Hereafter we aggregate all the protocols built upon Blockstore, by identifying them with Blockstore itself.

To verify this conjecture we would need to compare the transaction identifiers of our empty transactions with the identifiers of [35], which are not available online.

The release notes of Bitcoin Core version 0.9.0 state that: “Storing arbitrary data in the blockchain is still a bad idea; it is less costly and far more efficient to store non-currency data elsewhere.”.
