In a significant development, the latest version of Bitcoin 
$75,013 Core software has removed the 80-byte limit previously imposed on the OP_RETURN function. This update permits embedding larger data packets and creating multiple OP_RETURN outputs within a single transaction. The changes aim to align with modern mining practices by enhancing data storage flexibility, as noted by the developers.
Lift on OP_RETURN Byte Limit
Initially, the OP_RETURN opcode faced restrictions, constrained by an 80-byte limit for adding data onto the Blockchain. The recent update now allows recording larger data packets in blocks, and it has become feasible to create multiple OP_RETURN outputs in a single transaction. Developers implemented this update to modernize system policies in line with current mining methodologies.
Previously, the limit enabled miners to validate transactions and reduce storage costs. However, strict limitations regarding data size are no longer present. Experts suggest that this flexibility could pave the way for new data processing scenarios on the blockchain. Long-term performance monitoring will be conducted to analyze efficiency concerning block performance.
OP_CAT Revival and Smart Contract Implications
Meanwhile, the proposal to reactivate the OP_CAT opcode has surfaced, potentially advancing smart contract applications. OP_CAT enables the concatenation of data pieces, simplifying complex programming steps on-chain. This revival could theoretically allow more dynamic and flexible smart contracts on the Blockchain.
However, consensus within the community has yet to be achieved. Greg Sanders expressed support by declaring, “The long-standing 80-byte limit is now effectively over.” In contrast, Luke Dashjr criticized the change, labeling it “illogical.” Samson Mow alluded to potential shifts by users towards older versions. Marty Bent highlighted that a clear consensus has not been reached on the matter.
Bitcoin’s price has significantly increased recently. This update is anticipated to be part of market fluctuations and developments about crypto reserve news. As some US states prepare to form crypto reserves, the amendment opens up new discussions regarding network functionality.
