The Bitcoin blockchain was used to certify the results of a local Republican convention in Williamson County.
On March 4th, during the Republican convention in Williamson County, Tennessee, the Bitcoin blockchain was employed to ensure the integrity of the election results.
Simple Proof, a company specializing in protecting public documents via Bitcoin’s distributed ledger, was called in to preserve the authenticity of the voting results. Using the “Immutable Proof” service, which employs the OpenTimestamps protocol, the final results were permanently recorded in block number 886,370.
Simple Proof protects digital documents by embedding a “copy” of them in a Bitcoin transaction, utilizing a feature called OP_RETURN.

The elections saw two factions—“Elevate” and “Williamson County Republicans”—competing, each with a list of eight candidates. Only “bona fide” Republicans, those who voted in at least three of the last four Republican primaries, were allowed to vote.
On-chain data shows that Steve Hickey was elected chairman of the local convention, Tim Raynaud won the vote to become treasurer, and Leigh Ann Cates was elected secretary of the organization.
This is not the first time Bitcoin’s timechain has been used in a voting context, due to its immutability, transparency, and decentralization features.
In 2023, Simple Proof helped secure the election results in the Guatemalan presidential elections, a story told in the short documentary Immutable Democracy. The company also helped preserve the integrity of election results in Screven County, Georgia, last November.
