Encoding art into the satoshi value field, and the unfilterable floor

This innovative approach embeds an image directly into the satoshi values of spendable Bitcoin outputs, where each dot represents a real payment and the amounts, when read in sequence, form an image. The art is essentially comprised of the denominations used in these transactions.

In this system, the encoding method utilizes the value equals offset plus data byte formula, with the offset set at the Pay-to-Witness-Public-Key-Hash (P2WPKH) dust floor of 294 satoshis. This setup ensures that each output carries one byte of compressed image data in its amount, and the total output count matches the byte count of the image data. The image itself is compressed using CCITT Group 4 standards before being segmented into outputs. Additionally, metadata such as a magic byte, a codec identifier, and the dimensions of the square are ingeniously packed into the four bytes of nLockTime using the Lockchain Protocol layout, which also ensures the transaction remains final by making the resulting value reflect a past timestamp.

This method does not require any OP_RETURN data, witness payloads, script encodings, or consensus changes, maintaining full standardization and compatibility with default node relays. Transactions recreate the same values to a new canvas address while preserving the integrity of the data, as reducing a data value could corrupt the information contained within each byte. The relay limit for a single transaction is set at 100,000 virtual bytes, capping at about 1010 outputs, but techniques like sharded sweep and re-mint can extend this up to approximately 3225 outputs. Larger pieces necessitate multiple transactions due to these constraints.

A crucial aspect of this methodology is that it challenges conventional data filtering on the blockchain. Since the data resides solely in the amount field, no relay policy can reject it without imposing restrictions on the permissible satoshi values, transforming what would be a data filter into a payment restriction incompatible with the ideas of permissionless money. This premise exemplifies that while data filtering might be feasible elsewhere on the chain, it cannot penetrate the layer that every payment must utilize. Such an arrangement underscores a broader philosophical debate similar to Yves Klein’s 1962 artistic endeavors, where art and monetary value intertwine irreversibly.
