SonicLabs (formerly Fantom) co-founder Andre Cronje said that for all L2 or application chains, the true cost of running a blockchain (even if semi-successful) is: oracle, stablecoin upfront fee of $7.50 million, $3.50 million per year; RPC, index, Dashboards upfront fee of $200,000, $700,000 per year; VRF, Keepers, wallet support, governance $500,000 per year; Explorers, escrow, risk management $800,000 per year, total $13.20 million. The above applies only to Sonic. Here's how we spent last year: $10.90 million for R & D; $10.70 million for ecology; $410,000 for legal; $3.80 million for compliance; $2.40 million for infrastructure; $1.40 million for marketing; $1.20 million for bounties; $400,000 for sponsorship; $350,000 for media; $200,000 for regulation; $100,000 for events; and $35.60 million for total costs. (The above does not include exchanges going live, which fortunately we don't need to do this year)
