Bitcoin Core v30: OP_RETURN Removal Sparks Debate Over Decentralization and Network Flexibility

Bitcoin’s latest update, version 30 (v30), has brought a long-anticipated change to the network – the removal of the OP_RETURN data limit. This shift, previously debated by developers and users alike, now raises concerns about decentralization and network sustainability. 80-byte limits on OP_RETURN transactions have been lifted, allowing for far larger data payloads within each transaction output. While supporters view this as a step towards enhanced user control and flexibility, critics warn of the potential for increased spam, network congestion, and ultimately, centralization.
