According to the news from Bijie.com, on May 21 (UTC+8), Martin Köppelmann, co-founder of Gnosis, launched the Circles v2 protocol, integrating components such as Metri Wallet, Safe, CoW Swap, and built on Gnosis Chain. The experimental project attempts to create a "community-owned currency", with each member automatically receiving 1 exclusive ERC-20 token every hour, with a daily output of 24. One of the main improvements of Circles v2 is the addition of GnosisPay, a non-custodial, Visa-backed card and crypto payment solution. V2 also introduces the concept of "Group", which is a collection of different Circles united under a common ERC-20, thereby improving fungibility. Köppelmann said that Circles achieves decentralized currency issuance through a hard-coded allocation mechanism (rather than a Bitcoin-style supply cap), and its value depends on community consensus - it can be regarded as an IOU or exchangeable for physical objects. Users need to "connect" to each other to make tokens meaningful, and this design is intended to solve the centralization problem of early Bitcoin holders. Ethereum founder Vitalik Buterin once commented on the project as a "quasi-universal basic income experiment." (Source: PA Coin World)
