Bitcoin Records U.S. Constitution Again... This Time with a Mysterious Code

Galaxy Research tracks 562 mysterious strings recorded on Bitcoin over three weeks

Recorded 40 times a day... Attempts to decode the cipher proved it to be random strings

Tracing funds linked to a wallet that recorded the full text of the U.S. Constitution last May

[Block Media Reporter James Jung] An anonymous wallet that made headlines last May by engraving the full text of the U.S. Constitution on the Bitcoin blockchain has now been found to be repeatedly recording strings of unknown identity. Strings that appear to be ciphers are appearing on the Bitcoin network about 40 times a day.

On the 25th (local time), Galaxy Research revealed the results of analyzing 562 suspicious strings recorded on the Bitcoin blockchain over the past three weeks via X. Galaxy Research analyzed that while these strings appear to be encrypted secret messages, they are actually random combinations of characters generated by an automated program.

Even more interesting was the source of the funds. Tracing the transaction history, Galaxy Research found that the Bitcoin used in this activity was linked to the wallet that recorded the full text of the U.S. Constitution last May.

Mysterious Code Appearing on Bitcoin... Repeated 40 Times a Day

One of the strings released by Galaxy Research is as follows.

"Dosjt uxnhhwdzcu vamifqs, erjqupvsq ppatn lqk avxg. Okt kvwpbrmnsc sqqf afyera lrqvgylbfw, yxc. Rlelbtuem lbiutuy." OP_RETURN record engraved with the mysterious code. It is recorded at block height 972914 on the Bitcoin blockchain. Source: MemPool Space

At first glance, it looks like an encrypted English sentence. There are spaces between words and even a period, but it cannot be interpreted as a typical English sentence. Galaxy Research conducted a statistical analysis to verify whether this string is indeed a cipher.

Upon investigating the frequency of the 26 letters used in the 562 strings, it was found that the proportion of each character ranged from 3.6% to 4.2%, appearing almost evenly. In standard English, the most frequently appearing letter, "e," has a frequency of 12.7%, while "z" is only 0.07%.

In other words, if it were a simple substitution cipher where letters are replaced with other letters, the frequency would not appear evenly. The research team also examined the Vigenère method, which uses a repeating cipher key. If a cipher key of a specific length exists, statistical patterns should appear at multiples of that length, but no such signals were found even after analyzing up to 40 characters.

Ultimately, Galaxy Research concluded that these strings are merely randomly selected letters rather than secret messages.

Automated Bots Operating Day and Night... 31 Transaction Connections

A certain pattern was discovered in the way the strings were recorded. According to Galaxy Research, each transaction consisted of one input, one new change address, and one OP_RETURN output. OP_RETURN is a feature that allows arbitrary data to be recorded in Bitcoin transactions. Using this feature, sentences or information unrelated to monetary value can be left on the blockchain.

The problematic transactions were linked in a way that the Bitcoin remaining from the previous transaction was used as the funds for the next transaction. Galaxy Research found 31 such transaction connection structures. The longest connection extended to 86 transactions. The funds required for the transactions were supplied in units of 20,000 satoshis or 5,000 satoshis.

There was also a pattern in the recording times. Long strings were recorded every 6 hours in each transaction connection structure, while short strings were recorded approximately every 90 minutes. The daily recording frequency increased from an initial 12 times to 24 times, and recently reached about 40 times. Transactions recording long strings showed a pattern of being approved within one hour around 5 AM, 11 AM, 5 PM, and 11 PM UTC.

Starting from October 10, a second transaction connection structure appeared, differing by one hour from the existing schedule. Based on these characteristics, Galaxy Research suggested that it is highly likely that an automated bot in the form of a cron job, which executes a program at set times, is generating the transactions rather than a person doing so manually.

Tracing Funds Links to the U.S. Constitution Recording Incident from 5 Months Ago

So, who is behind this mysterious activity? Galaxy Research was able to trace back through the 31 transaction connection structures to reach a specific wallet. They discovered that it was linked to three small withdrawals made at a cryptocurrency exchange last May.

The total withdrawal amount was 0.033 BTC. The source of these funds was the same as that used to record the full text of the U.S. Constitution on the Bitcoin blockchain last May. Previously, Bitcoin Magazine reported on May 29 that an unidentified individual had recorded the full text of the U.S. Constitution on the Bitcoin blockchain. (See the X post below)

The text of the Constitution begins with "We the People of the United States" and includes the 27 amendments. The individual or organization that recorded the U.S. Constitution at that time did not disclose their identity and provided no explanation for the purpose of the recording.

If Galaxy Research's analysis is correct, it means that the Bitcoin used to record the U.S. Constitution about 5 months ago is now being utilized for activities that repeatedly record strings without discernible meaning.

Engraving the Entire Document on Bitcoin... Reigniting the OP_RETURN Debate

This incident is also connected to the issue of using the Bitcoin blockchain for purposes other than monetary transactions. Bitcoin is a network designed to record and verify transaction histories, but by utilizing OP_RETURN, additional data can be included in transactions.

In the past, Bitcoin Core software limited the size of OP_RETURN data to 80 bytes in standard transaction relay policies. However, in Bitcoin Core v30, this restriction and the limit on the number of OP_RETURN outputs per transaction were removed. There has been ongoing debate within the Bitcoin community regarding this expansion of data recording.

Some developers argue that since users can bypass existing limits to record data, maintaining artificial size limits is ineffective. On the other hand, others worry that recording large amounts of arbitrary data could conflict with the original purpose of keeping Bitcoin as a monetary network.

From the U.S. Constitution to Random Strings... Who is the Anonymous Recorder?

Galaxy Research has found connections between the statistical characteristics of the strings, transaction generation times, transaction structures, and fund movement paths, linking the recent automated activities to the U.S. Constitution recording incident from 5 months ago. It remains unclear who is generating these transactions, why the U.S. Constitution was recorded, and why they began repeatedly engraving random strings 5 months later.

Whether this is a simple technical experiment, a test of the Bitcoin network's data recording capabilities, or serves another purpose is also uncertain. What Galaxy Research has confirmed is that the strings do not appear to be typical ciphers and that the transaction funds are linked to the past U.S. Constitution recording incident.

The Bitcoin that recorded the meaningful document of the U.S. Constitution is now continuously leaving behind strings that are difficult to find meaning in. While statistical answers about the identity of the cipher have emerged, the entity recording it and its purpose remain a mystery.
