Launched when OFAC-related censorship peaked at approximately 78%, our relay was instrumental in reducing this censorship by half, down to around 29%. However, censorship has been climbing again in recent months, highlighting the ongoing need for our efforts to maintain Ethereum’s foundational principles.\n\nToday, ultra sound relay is the preferred choice for proposers about 42% of the time. Our small team keeps the relay competitive and accessible to everyone. This benefits not only proposers but also empowers individuals interested in block building to participate in the most competitive block auctions available.\n\nOperating an effective relay is resource-intensive, costing roughly $20,000 per month, processing thousands of block bids, in multiple geographies, each slot. Until now, the project has mostly been funded by generous supporters who share our vision. Continued active development is crucial to maintain and enhance this infrastructure, ensuring it remains open and competitive for all participants.\n\nBy supporting ultra sound relay, you contribute to strengthening Ethereum’s foundational infrastructure, aligning with shared goals of scalability, security innovation, and decentralization. Your grant will help sustain and advance a project that has immediate and long-term impacts on where people build, transact, and entrust their capital within the Ethereum ecosystem.", "lastUpdated": 0, "projectGithub": "ultrasoundmoney", "projectTwitter": "ultrasoundmoney"}, "recipient": "0x52F8592BaAf3B90bC94Cb52F06C086080858e4d7"}}
