Bitcoin\u2019s next major software release, Bitcoin Core v30.0, has reignited a fraught debate over what kinds of data should be permitted to traverse and settle on the network\u2014and who could bear legal responsibility when that data is illicit.<\/p>\n

On Monday, cryptography pioneer Nick Szabo<\/a> weighed in with a pointed warning: changes in v30.0 that relax long-standing relay policies for data-carrying transactions may heighten the legal exposure of full-node operators by making objectionable content easier to retrieve and \u201cview\u201d with everyday software, thereby strengthening claims that operators had knowledge of what they were relaying or storing.<\/p>\n

Bitcoin Core V30 Update Could Be A Legal Disaster<\/h2>\n

Szabo framed<\/a> the core issue in stark terms: \u201cWhat then happens when full node operators become informed about illegal content on the blockchain? They then have knowledge and this particular precedent doesn\u2019t protect them.\u201d He added that the risk is not abstractly technical but turns on how non-technical decision-makers\u2014lawyers, judges, and jurors\u2014perceive what a node operator could reasonably know or do.<\/p>\n

\u201cA counter argument is that illegal content in a contiguous standard format, thus readily viewable by standard software, is more likely to impress lawyers, judges, and jurors\u2026 than data that has been broken up or hidden,\u201d Szabo wrote, stressing that legal outcomes can hinge less on protocol nuance than on whether a \u201cone-click\u201d consumer app can surface the content.<\/p>\n

The flashpoint is Bitcoin Core v30.0<\/a>\u2019s reversal of an informal barrier around OP_RETURN\u2014the script pathway historically used to attach small, prunable blobs of arbitrary data to transactions. For years Core\u2019s default mempool policy would not relay OP_RETURN payloads above ~80 bytes and limited them to one output per transaction, a non-consensus \u201cstandardness\u201d rule that deterred large data postings without banning them at the protocol level.<\/p>\n

\u201cFees protect the miners, but they don\u2019t provide enough disincentive to protect the full nodes. This has always been a problem, of course. But increasing the OP_RETURN allowance will likely make this problem worse. It also will increase legal risks,\u201d Szabo wrote via X.<\/p>\n

Beginning with Bitcoin Core v30.0, the default policy shifts: nodes will by default relay and mine transactions with larger aggregate OP_RETURN data and permit multiple data-carrier outputs per transaction; the long-used -datacarriersize knob is being deprecated and repurposed, and now applies to the aggregate data across outputs. In effect, the default barrier comes down\u2014though individual node operators can still set stricter local limits.<\/p>\n

Core developers and supporters of the change argue that channeling non-financial data into OP_RETURN\u2014precisely because it is prunable\u2014can reduce systemic harm compared with stealthier encodings in non-prunable parts of transactions (e.g., faux public keys or other script hacks). As Szabo summarized the pro-Core position he has \u201cheard\u201d: allowing more data via OP_RETURN \u201cconceivably may reduce legal risks,\u201d since the alternative (hiding data in places that are not pruneable) is worse for the long-term burden on nodes.<\/p>\n

Critics counter that relaxing defaults will normalize large, contiguous data payloads that consumer apps can trivially render, making it far easier for prosecutors to demonstrate that node operators had actual or constructive knowledge of illicit material. As Szabo put it, non-technical decision-makers will be \u201cmuch more impressed\u201d by illegal content that a familiar app can retrieve than by content requiring specialized tools. That persuasion risk, he suggests, is at the heart of operator liability.<\/p>\n

The legality question sits awkwardly at the intersection of these technical defaults and real-world perception. Several industry participants argued in response to Szabo that arbitrary data cannot realistically be stopped at all\u2014whether via inscriptions in witness data, encodings in public keys, or OP_RETURN\u2014making the policy debate \u201cfruitless.\u201d Szabo did not dismiss that practical reality but insisted that format and user-experience matter in court: if \u201can app like one on their phones can retrieve the data,\u201d that could weigh heavily against a defendant Bitcoin node operator; if it requires obscure reconstruction tools, the opposite.<\/p>\n

What, then, is the remedy? Szabo floated two classes of mitigations, both imperfect. At the software level<\/a>, he suggested making it deliberately harder for popular apps to store and retrieve generic media via either OP_RETURN or witness data\u2014essentially nudging developers away from contiguous, human-readable formats.<\/p>\n

At the policy level, legislators could consider liability regimes that focus on the signers of offending transactions rather than on relay\/storage intermediaries such as node operators. He also emphasized heterogeneity: because legal risk and the app landscape vary by jurisdiction and over time, Bitcoin node operators need freedom to develop \u201cmessy, social\/technical solutions,\u201d with an eye on avoiding spillover into censorship of ordinary payments.<\/p>\n

Notably, Szabo stressed that he has not taken a definitive side on the update and is \u201cexploring the issues,\u201d even while cautioning that \u201clegal issues like this are far from straightforward, and they lie far outside the wheelhouse of most developers.\u201d That, perhaps, is the most sobering takeaway as v30.0 approaches: the technical path may be clear, but the legal terrain it crosses is anything but.<\/p>\n

At press time, Bitcoin traded at $112,079.<\/p>\n
