SubEthaNomic(SEN)

The SubEthaNomic contract was deployed at block 689715 on December 14, 2015, by address 0x157d22269fdF6bF34050d7Ab74b8cd27a3916265. The contract stores the token name SubEthaNomic with the ticker symbol SEN. The name appears to be a compound of Sub-Etha, the fictional galactic information network from Douglas Adams's The Hitchhiker's Guide to the Galaxy, and the suffix -Nomic, a suffix common in economic and governance contexts.

The contract received eight transactions, all from the deployer address. The initial deployment at block 689715 was followed by a series of function calls at blocks 694635, 694639, and 694642 within a twenty-four hour period, and again at block 717179 approximately two weeks later. The pattern of repeated same-address interactions suggests the deployer was testing or actively using the contract's transfer and balance functions.

The contract was deployed using no verified source code on Etherscan, but the token name and symbol data stored on-chain confirm its identity. The deployment falls in the late Frontier era, approximately five months after Ethereum's launch and two months before the Homestead upgrade in March 2016.

By December 2015, the practice of naming tokens after cultural references had begun to emerge in the Ethereum community. The ERC-20 standard had been formally submitted on November 19, 2015, two weeks before this deployment, though widespread adoption of the standard was still months away.
