In short
- An anonymous Bitcoin user posted the text of the American Constitution on the Bitcoin blockchain.
- This trend was made possible thanks to the OP_RETURN field and the removal of last year’s byte limit.
- The user paid $83 to complete the task, although it is not known who wrote the text.
We the people of the cryptocurrency ecosystem… can now read all US laws directly from the Bitcoin blockchain.
The project was accomplished late Thursday when an anonymous Bitcoin user posted a copy of the document on the immutable blockchain, making it available on-chain for as long as the network has existed.
The 44.4 kilobyte transaction – worth the size of a Bitcoin – costs the user about $83.41 in transaction fees, according to blockchain explorer.
In comparison, other, simpler Bitcoin transactions at the same time-if the transfer is around 0.01 BTC– registered at only 227 bytes, or around 0.5% of its size as written. Even if you pay more than 105x, the transaction costs only $17, or about 20% of the Constitution.
Nothing says freedom like paying 83 cents to commit these rules to the blockchain forever

Meanwhile, critics called it a change in the original nature of the Internet, from financial services to data storage.
Since the removal of the byte limit, a an idea they are designed to deal with unstructured data.
Records are not new to Bitcoin, which was swept in the year 2023 when the system grew so large that mempool has reached its limit since the data was collected.
Before this, great interest in Bitcoin Ordinals-or the equivalent of NFTs on Bitcoin-caused major debates about the blockspace as Bitcoin prices rose and increased it has resulted in large unconfirmed sales figures.
Like the Constitution’s text, Bitcoin’s Ordinals standard led to the writing of images, text, gameand audio on the Bitcoin blockchain. For example, a social media post from the hacked account of former SEC Commissioner Gary Gensler accepting Bitcoin ETFs in 2024 he was written on the Internet forever.
It is not immediately clear why someone decided to spend $83 to write the US Constitution on the Bitcoin blockchain; so far, no one has publicly claimed responsibility for this.
One of America’s most famous documents, the crypto world already has a history with the US Constitution, which was signed just one year after America declared its independence in 1776.
In 2021, ConstitutionDAO, an autonomous organization (DAO) or group of users with a shared purpose, earned more than $45 million with the hope of winning a rare copy of the document through trade. An organization that is now defunct lost billionaire Ken Griffin.
