Crypto PAC Backs Husted; Bitcoiners Propose Freezing Satoshi’s BTC

Sentinel Action Fund announced Wednesday it will endorse Republican Jon Husted in Ohio’s May 5 Republican primary for the U.S. Senate. Husted was appointed by Ohio Governor Mike DeWine in January 2025 to fill the seat vacated by JD Vance after Vance became vice president.

The PAC describes itself as a conservative super PAC that supports candidates who back pro-crypto innovation. President Jessica Anderson criticized former Senator Sherrod Brown for opposing digital asset policies and cited that opposition when explaining the endorsement. Brown is expected to face Ron Kincaid in the Democratic primary. Husted faces multiple Republican challengers ahead of the primary.

Separately, Jameson Lopp and five co-authors posted a draft Bitcoin Improvement Proposal called BIP-361 to GitHub on Tuesday. The draft is the second stage of a three-part plan titled “Post Quantum Migration and Legacy Signature Sunset.” It proposes a mechanism to freeze legacy pay-to-public-key (P2PK) outputs that expose public keys on the blockchain.

Early P2PK addresses reveal the public key when funds were spent or created, and the draft’s authors say that future quantum computers could use those public keys to derive private keys and move funds. The proposal targets roughly 1.7 million BTC held in early addresses often associated with the network’s first participants. The draft explains a process to freeze those outputs to prevent them from being swept by parties with quantum capabilities while migrating coins to quantum-resistant address types.

The proposal remains a draft and would require extensive community discussion and coordination before any protocol changes could be deployed on the Bitcoin network. The authors present the freeze as one part of a staged migration intended to phase out legacy signature types and adopt quantum-resistant schemes.

In Europe, Danmarks Nationalbank published a staff paper reporting that 4% of Danish residents hold cryptocurrencies, a share unchanged since 2023. The finding is based on a survey of 3,013 citizens aged 15 and older conducted between October and November 2025 through Denmark’s Digital Post system, with responses by online form or phone. Most respondents who hold crypto reported positions below 10,000 Danish kroner, and the central bank estimated total national holdings between $317 million and $847 million.

The Danish adoption rate reported in the paper is lower than figures cited for several other European countries, where reported ownership exceeds 10 percent of the population. The paper’s authors weighted the sample to reflect national demographics and framed the results as a snapshot of household-level exposure to crypto assets.

Political action committees aligned with the cryptocurrency industry expanded activity in the 2024 U.S. election cycle. Some of those groups have continued to endorse and support candidates in 2025 at state and federal levels. The Bitcoin community has discussed quantum risk for years; any protocol change to address that risk would require broad agreement among developers, miners, node operators and users before implementation.
