Cardano founder Charles Hoskinson has responded to a renewed controversy within the Bitcoin ecosystem, stating that recent developments align exactly with his earlier predictions. His comments follow a brewing debate over Bitcoin’s transaction relay policy and the use of non-financial data on the blockchain, a concern some developers say could undermine the network’s core principles.
Bitcoin Core Proposal Raises Alarm
The debate centers around OP_RETURN, a Bitcoin protocol feature that allows users to attach small amounts of data to transactions. A recent proposal in Bitcoin Core aims to relax transaction relay policies, which critics argue could open the door for the transmission of gigabytes of arbitrary data through the Bitcoin network, even before the data hits the blockchain.
This proposal has sparked fears about blockchain bloat, a condition where excessive non-financial data strains node performance, slows down transaction processing, and unnecessarily inflates the blockchain’s size.
Hoskinson Responds with “Told You So”
Hoskinson weighed in with a sarcastic GIF on X (formerly Twitter), suggesting that everything is unfolding “just as he predicted.” His reaction came in response to a post by Jason Hughes, a Bitcoin developer, who voiced strong concerns about the pull request.
Hughes warned that such permissiveness in Bitcoin Core’s relay rules could have long-term consequences. He recommended switching to Bitcoin Knots, a version of the Bitcoin software maintained by Luke Dashjr, which applies stricter transaction filtering policies. Hughes also appealed to top mining pools, including AntPool and ViaBTC, urging them to reject the proposed update to preserve Bitcoin’s intended minimalist design.
Cardano’s Take on Bitcoin Wallet Shortcomings
Hoskinson’s involvement in this debate follows earlier critiques from within the Cardano community, particularly from Cardano DRep Psiloblox. He criticized Bitcoin wallets for failing to support OP_RETURN functionalities adequately.
Psiloblox emphasized how most Bitcoin wallets miss the opportunity to let users embed messages into their transactions. As Cardano’s Lace wallet explores Bitcoin integration, he pointed out that Moonshine wallet already allows OP_RETURN messaging, including QR code scanning and HEX text conversion features.
He also mentioned that he had previously suggested adding similar functionality to Bitkit, but the idea hadn’t gained traction at the time.

Developers Propose Protocol-Level Safeguards
Adding to the discussion, renowned developer Peter Todd shared his thoughts on how to control the inclusion of non-financial data better. While he acknowledged that Bitcoin Knots implements a more conservative approach, Todd noted it still permits certain data-heavy, spam-like transactions.
To address this, Todd proposed a potential soft fork to introduce new transaction constraints. Under these rules, only hash digests or public keys would be allowed as embedded data, making it computationally expensive to insert irrelevant content. However, Todd cautioned that such a move would not eliminate spam, especially from token trading or related metadata.
As Bitcoin’s user base grows and developers explore more complex use cases, the balance between innovation and network integrity becomes increasingly challenging to manage. Hoskinson’s reaction underscores Cardano’s commitment to maintaining a clean, purpose-driven protocol, in contrast to what he views as potential degradation in Bitcoin’s core ethos.
This ongoing discussion may influence both protocol decisions and wallet innovations moving forward, as developers strive to ensure that blockchain networks remain efficient, secure, and aligned with their original mission.
