OneName was an ID service provider for the Blockstack network, active from 2014-2017 at, now known as They stored the user profile data on the Namecoin blockchain as their back-end, including links to avatar and cover images, mainly from the Twitter platform. These external assets are considered NFTs (Non Fungible Tokens) in today's common sense.

For the basic data, OneName used the u/ namespace, which was extended by the i/ namespace if the data didn't meet Namecoin's 520-byte limitation for the value field. In rare cases, only records in the i/ namespace were used. The founders and core developers of OneName created the first back-end records on Monday, 24th of February 2014, 08:27:31 (GMT/UTC) at block 163,986:

In autumn 2021, in the wake of the global NFT hype, the crypto community began to re-register all OneName NFTs after realizing that these NFTs in the common sense, including links to external images, are the oldest NFTs in the crypto universe. Some bot-script operators started to systematically re-register thousands of entries, trying to restore the original value. Unfortunately, due to poorly coded scripts, a not insignificant number of entries were renewed with incorrect data, most likely caused by a loop script and non-unset variables. Other entries seem to have been intentionally renewed with incorrect data by copying the data from valuable assets to entries without any financial value. Also, several fake entries were recently created with this data, giving the impression of being original OneName records. All records shown on were filtered through a multi-step process by different systems and selected based on their original name updates with a block height < 500,000. If you check the data with a blockchain explorer, make sure to verify the asset's history!

Sortable tables

All images shown in the tables are previews only with 50 px height. created an archive of all accessible and valid NFT links in June 28, 2022. All file names were prefixed with the name of the respective Namecoin asset, with the slash of the namespace replaced by an underscore. In case of a linked pair of records in the u/ and i/ namespaces, both containing the same image, two separate files were created. If the first data entry containing an NFT link to an external image was invalid, the name history was rescanned once and the next entry was taken if the file check succeeded. While this was the case for about 100 assets only out of more than 38,000, there could still be very few where only the third version of an NFT link was valid; those assets would not be listed. Below are the statistics of the archive:

• 16,190 avatar files
• 7513 individual cover files
• 41 common covers
• 7554 total cover files

23,744 total NFT files

The block height of the Namecoin asset refers to the firstupdate operation on the blockchain, which is preceded by a name_new operation. Latter has no relevance from both a cryptographic and a legal point of view, since the new name operation merely creates a reserved spendable transaction output only, with the standard value of 0.01 NMC and a minimum safety margin of 12 blocks from the final cleartext registration. The new name operation can also be issued while the name is still active and can therefore never be used to calculate the age of the asset. Therefore, new name operations won't even be shown in the history of the asset requested by the name_history RPC command (Remote Procedure Call) via the console of the software wallet. The Namecoin asset is created or re-registered solely with the firstupdate operation, which guarantees cryptographic ownership for 36,000 blocks.

Once the Namecoin asset is created, it persists forever, even after expiration and following re-registration, with the entire history assigned immutably. Obtaining the private key of an active registration grants ownership of the asset and the cryptographic token currently assigned to it. Since the minting date of an NFT link does not necessarily match the creation date of the cryptographic Namecoin asset itself (the key/value pair of the blockchain record), both block heights are shown. The NFT referencing an external asset was created by a name_update operation in this case, see Register NFTs for details. If the avatar or cover image has changed while the OneName profile was live, the first NFT will be shown. More details may be found by a lookup with our blockchain explorer or via the console of a Namecoin software wallet. However, all NFTs will be shown on the detail pages of the auctioned assets.
