# Ethereum

Since August 2022

For the final leg of a trek on digital platforms, [daqhris](https://app.ens.domains/daqhris.eth) publicly minted the set of 263 photographs, which he had miraculously recovered after another chaotic winter.

Blessed by the angelic support of a cryptocurrency wallet, that had been activated in [2017](https://etherscan.io/address/0xb5ee030c71e76c3e03b2a8d425dbb9b395037c82#analytics), bootstrapped in [2021](https://platform.arkhamintelligence.com/explorer/entity/daqhris), and put to use in [2022](https://etherscan.io/txs?a=0xb5ee030c71e76c3e03b2a8d425dbb9b395037c82\&f=5), he preserved them for the long run as non-fungible [ERC-721 tokens](https://ethereum.org/en/developers/docs/standards/tokens/erc-721/) on the Ethereum blockchain.

[Ethereum](https://ethereum.org/) is a decentralized blockchain platform that allows developers to deploy self-executing code in the form of smart contracts and applications. The artworks were wrapped in a smart contract, recorded in the public ledger as [**awalkaday.art**](https://eth.blockscout.com/name-services/domains/awalkaday.art), and self-published so that they can be preserved, collected and exchanged. The smart contract address is [`0xE31801C2E58b151C3deD2cB29dA56147b7f27eB1`](https://etherscan.io/address/0xE31801C2E58b151C3deD2cB29dA56147b7f27eB1) and its source code has a file on-display below. Its ASCII art depicts the `awalkaday` logo encoded in the contract itself.<br>

The monochromatic snapshots were assembled, named, and minted during a wintertime stay as a homeless person. The location: the ironically-named [Palais des Droits](https://archive.is/2JkUB), a state-owned financial building which had been converted into a squalid squat. He publicly safeguarded them on a financial network of computers on [Valentine's Day](https://etherscan.io/tx/0x2d4e5a73fada3bb3e626bec4b2d24bbdabce66fad66b70fbe8e3e0e1e169537b) in 2023, fortunately one day before a [scheduled eviction](https://www.lalibre.be/belgique/societe/2023/02/09/schaerbeek-le-palais-des-droits-sera-vide-pour-le-15-fevrier-J4FJQRA6UBGYNA2I4KKPDM27LA/) from the infamous shelter in Schaerbeek.

Once released into a sovereign financial ecosystem, the fear of losing the `awalkaday` photographs vanished into thin air, transcended the confines of his last encrypted device — the Android One — whose secure updates had been halted near the [end of 2022](https://source.android.com/docs/security/bulletin/2022-12-01).

After landing on a blockchain terrain in a batch series, each photo began to carry a name, similar to the title of a page in a logbook, for example: [`awalkaday 185-2022`](https://app.zerion.io/0xb5ee030c71e76c3e03b2a8d425dbb9b395037c82/nfts?collections=85657215).

Each name is a string of words and numbers that begins with the artistic theme `awalkaday`, then ends with a computer-calculated [day of the year](https://asd.gsfc.nasa.gov/Craig.Markwardt/doy2025.html), linked by a hyphen to the year of when the photo was first dropped online without a parachute, and crossed the radar of [cyberwarfare forces](https://en.m.wikipedia.org/wiki/List_of_cyber_warfare_forces) without a travel visa.
