Etheria

Etheria v1.2 was deployed at block 470,957 on November 1, 2015 (01:20:11 UTC), by the pseudonymous developer of the Etheria series. It is the third public release of the Etheria on-chain virtual world, following v1.0 (block 420,373, October 22) and v1.1 (block 459,708, October 29). Like its predecessors, the contract governed a 33×33 hexagonal tile map stored entirely in Ethereum state, where players could purchase unowned tiles for 1 ETH, farm them for building blocks, name their territory, and trade tiles through an in-contract offer system.

The rapid succession of versions—v1.0, v1.1, and v1.2 all deployed within eleven days in late October and early November 2015—reflects the early Frontier-era development culture, where iteration was fast and deployment was cheap enough to push new contract versions frequently. Each version refined the game mechanics while maintaining the core architecture: a fixed-size world, direct ETH-based tile purchase, and per-tile state including ownership, name, farming history, and open offers.

Etheria contracts were compiled with Solidity v0.1.6, one of the earliest released compiler versions. The source code is verified on Etherscan, making the full game logic publicly auditable. The deployer's address (0xcf684dfb8304729355b58315e8019b1aa2ad1bac) is consistent across all Etheria versions, confirming single-developer authorship.

Etheria v1.2 exists as a historical artifact of the earliest days of blockchain gaming and NFT concepts. The developer later noted in a 2021 site update that Etheria was "the first true NFT project in history, by more than a year," predating CryptoKitties (2017) and the ERC-721 standard (2018). Tiles from all Etheria versions—including v1.2—are now traded on the Etheria Exchange.
