Bitcoin Core developers are preparing to make a big change to the Bitcoin Core network. As revealed recently, developers are trying to remove the long-standing 80-byte size limit on OP_RETURN outputs. This change, expected in an upcoming software release, has caused debate among developers and Bitcoin community members. While some believe the update will help the network function better , others are worried it could increase spam and reduce efficiency. Understanding OP_RETURN and Its Role OP_RETURN is a part of the Bitcoin network’s scripting language that allows users to attach a small amount of data to a transaction. When someone uses OP_RETURN, the added data becomes part of the blockchain but cannot be spent or used again. This means it does not increase the size of the Unspent Transaction Output (UTXO) set, which is important for keeping the network efficient. The 80-byte size limit on OP_RETURN was introduced to prevent users from overloading the blockchain with large amounts of unnecessary data. However, during the ordinals and inscription boom in early 2024, users found other ways to store extensive data on the blockchain, often in ways that created problems for the network. Why Bitcoin Developers Want to Remove the Limit Bitcoin Core contributor Greg Sanders is pushing to remove the 80-byte limit. In a GitHub post on May 5, Sanders explained that the limit has outlived its usefulness. He emphasized that keeping the cap encourages users to find more harmful and complicated ways to store data on-chain. Sanders believes removing the cap entirely would lead to cleaner transactions and fewer bad workarounds. He says this move would promote transparency and reduce the strain on the network structure. Developers considered three possible ways to update OP_RETURN: keeping the 80-byte limit, raising the limit to a higher number, or removing the limit entirely. The first two were considered weak options, and developers felt they would not solve the problem. Removing the cap received the most support, although not everyone involved in the discussion supported it. Nevertheless, Sanders believes that this option will help keep the UTXO set clean and reduce transaction size pressure. It will also promote more honest and transparent use of the blockchain. Opposition and Concerns from the Community Not everyone supports the change. In a recent X post, Samson Mow, CEO of JAN3, said the update is “undesirable” and could lead to more spam and abuse on the Bitcoin network. Marty Bent, managing partner at Ten31 Fund, added that the move does not have broad agreement across the community. Others on social media have questioned the need for this change, calling it more symbolic than practical.
