Bitcoin developer Mononaut has expressed concerns over the proposed Reduced Data Temporary Softfork (RDTS), which aims to limit data-heavy transactions on the network. The proposal includes measures such as capping scriptPubKeys at 34 bytes and banning certain Tapscript logic. Mononaut warns that these changes could invalidate many historical transactions, including P2PK, P2MS, and over 54,000 witness version outputs. Critics of the RDTS argue that it could disrupt existing applications and lead to de facto censorship of transactions. However, proponents believe the soft fork is necessary to curb data abuse and mitigate legal risks associated with large transaction sizes. The debate highlights the ongoing tension between innovation and regulation within the Bitcoin community.
