Circle Internet Financial has announced that FOAM, a token associated with a consensus-driven mapping protocol, has joined the Poloniex exchange, marking another milestone for the team. Since acquiring Poloniex, Circle has been committed to offering a diverse range of assets that have the potential to advance the blockchain sector. FOAM is notable for its "Proof of Location" system, which allows for the private recording of authenticated location data independent of centralized sources like GPS. The FOAM network, which launched in September 2018, had previously locked its tokens during an initial Proof of Use period, but these tokens have now become transferable on the Ethereum blockchain. The exchange is implementing a "Post-only" mode to stabilize the market before full trading in BTC and USDC pairs begins. This addition to Poloniex is part of Circle's ongoing efforts to include innovative projects in its asset list, with more announcements expected soon. Users are advised to consider the volatile nature of crypto assets and review risk disclosures before trading.
