Bitcoin Core has raised the default -datacarriersize limit to 100,000 bytes and now permits multiple data-carrier (OP_RETURN) outputs in a single transaction for relay and mining. Crucially, node operators can still restore the previous behavior: \u201cIt can be overridden with -datacarriersize=83 to revert to the limit enforced in previous versions.\u201d The aggregate size limit applies across all OP_RETURN outputs in a transaction.<\/p>\n<p>That default increase\u2014functionally \u201cuncapping\u201d data carrier size because the transaction-size ceiling will be encountered first\u2014has kicked off a broader argument about what kinds of activity Bitcoin\u2019s policy layer should favor or discourage. Developers and node operators who back the change frame it as neutral plumbing that preserves operator choice; critics warn it <a href=\"https:\/\/bitcoinist.com\/bitcoin-spam-could-undermine-21-million-cap\/\" target=\"_blank\" rel=\"noopener \">invites more non-monetary inscriptions and potential spam<\/a>, raising storage and validation burdens for the average node.<\/p>\n<p>Beyond OP_RETURN, v30 delivers a long list of network, wallet, and tooling updates. The P2P layer improves package relay so that common topologies like grandparent-parent-child or multi-parent-one-child can propagate more reliably when only one ancestor needs fee bumping. The transaction orphanage introduces stronger DoS limits based on total entries and weight across peers, replacing the now-retired -maxorphantx knob.<\/p>\n<p>Miners gain an experimental IPC mining interface accessible through a new umbrella bitcoin command that also provides convenience aliases\u2014\u201cbitcoin node,\u201d \u201cbitcoin gui,\u201d and \u201cbitcoin rpc\u201d\u2014without deprecating existing binaries. External signing on Windows is re-enabled, and the coinstats index has been reworked to avoid an overflow bug seen on default Signet, requiring a one-time resync of that index.<\/p>\n<p>Fee-policy defaults also shift. The minimum block feerate setting (-blockmintxfee) now defaults to 0.001 sat\/vB, while both the minimum relay and incremental relay feerates default to 0.1 sat\/vB. The notes stress that unless these lower defaults are broadly adopted, propagation and confirmation are not guaranteed; wallet feerates themselves are unchanged without explicit configuration.<\/p>\n<p>The OP_RETURN policy change has quickly spilled beyond developer channels into Bitcoin\u2019s public discourse, with long-time contributors and publication editors lining up on both sides. While Bitcoin Core 30.0\u2019s larger data-carrier default and allowance for multiple OP_RETURN outputs are viewed by proponents as policy neutral and adjustable at the node level; detractors see a <a href=\"https:\/\/bitcoinist.com\/bitcoin-core-product-risk\/\" target=\"_blank\" rel=\"noopener \">vector for abuse<\/a> that blurs the network\u2019s monetary focus which could even <a href=\"https:\/\/bitcoinist.com\/bitcoin-hard-fork-plan-threatens-core-principle\/\" target=\"_blank\" rel=\"noopener \">spark a hard fork<\/a>.<\/p>\n<p>At press time, BTC traded at $114,455.<\/p>\n<p><img data-recalc-dims=\"1\" fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-604616\" src=\"https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?resize=1024%2C473\" alt=\"Bitcoin price\" width=\"1024\" height=\"473\" srcset=\"https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=3628 3628w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=640 640w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=768 768w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=980 980w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=1536 1536w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=2048 2048w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=750 750w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=1140 1140w, https:\/\/bitcoinist.com\/wp-content\/uploads\/2025\/10\/BTCUSDT_2025-10-13_08-04-10.png?w=3000 3000w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Bitcoin Core version 30.0 is now available, marking the project\u2019s first major release since v29 and closing the book on legacy branches 27.x and older, which are now designated \u201cEnd of Life.\u201d The maintainers\u2019 release notes state plainly: \u201cWith the release of this new major version, versions 27.x and older are at \u2018End of Life\u2019 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"iawp_total_views":0,"footnotes":""},"categories":[2],"tags":[3,4,5],"class_list":["post-52486","post","type-post","status-publish","format-standard","hentry","category-news","tag-crypto","tag-doge","tag-news"],"_links":{"self":[{"href":"https:\/\/dogewisperer.com\/index.php?rest_route=\/wp\/v2\/posts\/52486","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dogewisperer.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/dogewisperer.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/dogewisperer.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/dogewisperer.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=52486"}],"version-history":[{"count":0,"href":"https:\/\/dogewisperer.com\/index.php?rest_route=\/wp\/v2\/posts\/52486\/revisions"}],"wp:attachment":[{"href":"https:\/\/dogewisperer.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=52486"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/dogewisperer.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=52486"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/dogewisperer.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=52486"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
