About

10tance is a data processor to build virtual worlds from the state of an EVM chain. The core concept is the translation of an Ox address into a predictable location, giving objects (EOA accounts and contracts) a position and subsequently distance between them. ## An EVM world To each chain its own world. They will be displayed on an interactive 2d map. If you think the world is flat, I can tell you you are wrong because it is actually a doughnut ! Here they are indeed toruses, east connects with west and north with south : - it makes the projection s simple as on flat world - there is no edges as on a sphere world Same as with classical interactive maps, it will be composed of several layers fitting into two categories : ### Background layers They could be an addresses density map, market value density. Or even a procedural generated world : - the zero address would be a volcano where to burn tokens - the liquidity pools would be lakes and seas - the validator nodes would be mountains with mines - the EOA addresses houses ### Interactive points of interest Accounts and contracts shown as interactive locations. Searchable from their standard ERC interfaces, their addresses, their links to other objects ## Hackathon goals The aim for this hackathon is to build the building block for future emerging features related to two fields : data visualization and gamification. Some ideas and examples of what could be build on top of it are following. ### On the serious side of data visualization : - display metrics in a visual way - materialize links between contracts : liquidity pools with their tokens, tokens with their holders etc. - crowd curated directory of contracts ### On the fun side of gamification : - related to the data directory of contracts : a world discovery game where users navigate the map and explore contracts, describing and auditing or incentivize others to do it - a game to own the closest possible NFT to a sponsor contract - a game where holding an NFT would spread sovereignty over an area around. Leading to conflict and alliances

How it's made

# Done at submission time ## Database A PostgreSQL database with PostGis to store the locations along their metadata and to query them ## Indexer An ETL indexer using the Blockscout API as a source of data : extract addresses and identification, transform them into location, and load them into the indexed database. It currently shows data from the Optimism Mainnet. ## Application A NextJS application bootstraped with Scaffold-ETH It uses the leaflet library to display the map, tweaked to project a torus world on a specific coordinates reference system. ## Backend An Express backend server to serve : - The background tiles : they are currently mock images - The the objects of interest, retrieved from the indexed data # Missing - Actual background tiles generated from data - To fetch extra data from the Blockscout API at runtime - To create EAS attestations on displayed contracts.
