Bitcoin developer <a href=\"https:\/\/u1f987.com\/en\/news\/peter-todd-unlikely-creator-of-bitcoin\">Peter Todd<\/a>, who was <a href=\"https:\/\/u1f987.com\/en\/news\/peter-todd-refutes-hbos-claim-of-being-bitcoins-creator\">dubbed<\/a> the creator of the first cryptocurrency in an HBO documentary, <a href=\"https:\/\/u1f987.com\/en\/news\/the-op_return-war-intensifies-within-the-bitcoin-community\">proposed<\/a> lifting the limit.<\/p>\n<p>Sanders highlighted two main arguments for why the previously set 80-byte limit has become counterproductive and, in many respects, &#8220;destructive&#8221;:<\/p>\n<ul class=\"wp-block-list\">\n<li>it is easily circumvented \u2014 miners offer solutions to overcome the limit, and data recording occurs &#8220;more or less maliciously,&#8221; harming the network;<\/li>\n<li>it distorts incentives \u2014 users resort to &#8220;impolite&#8221; methods, including fake output keys from the <span data-descr=\"unspent transaction output\" class=\"old_tooltip\">UTXO<\/span> set.<\/li>\n<\/ul>\n<p>According to Sanders, Bitcoin Core developers considered three options:<\/p>\n<ul class=\"wp-block-list\">\n<li>maintain the limit \u2014 deemed ineffective;<\/li>\n<li>raise the threshold \u2014 any value will &#8220;age&#8221; over time;<\/li>\n<li>remove the restriction \u2014 aligns default policy with actual network practice.<\/li>\n<\/ul>\n<p>The innovation does not abolish the block limit of 4 million weight units. &#8220;Dust&#8221; outputs are still rejected, and signature and ancestor\/descendant operation limits prevent memory pool growth, the programmer emphasized. <\/p>\n<p>In his view, removing the 80-byte rule offers two main advantages:<\/p>\n<ul class=\"wp-block-list\">\n<li>a cleaner UTXO set \u2014 data is placed in a single unspendable output rather than being masked in scripts;<\/li>\n<li>consistent default behavior \u2014 nodes relay the same transactions miners want to see, making fees transparent.<\/li>\n<\/ul>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;The change affirms that Bitcoin is governed by transparent, minimal rules, not editorial preferences. By discarding a constraint that no longer works, Bitcoin Core maintains policy integrity and allows the fee market to arbitrate competing demands,&#8221; Sanders stated.<\/p>\n<\/blockquote>\n<p>Earlier, February&#8217;s <a href=\"https:\/\/u1f987.com\/en\/news\/bitcoin-on-chain-activity-hits-a-one-year-low\">decline in on-chain activity<\/a> on the Bitcoin network to an annual low was largely attributed by analysts to a drop in OP_RETURN outputs in transactions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The upcoming release of the Bitcoin Core client will by default allow more than 80 bytes of information in OP_RETURN outputs and permit any number of them.
