Sonic Labs co-founder Andre Cronje said in an article on X: "For all L2 or application chains, the real cost of running a blockchain (even if it is semi-successful) is:
The upfront cost of oracle and stablecoin is $7.5 million, and $3.5 million per year;
The upfront cost of RPC, index, and dashboards is $200,000, and $700,000 per year;
VRF, Keeper, wallet support, governance are $500,000 per year;
Explorer, custody, risk management are $800,000 per year, a total of $13.2 million. The above applies only to Sonic.
Here is our cost last year:
R&D $10.9 million;
Ecosystem $10.7 million;
Legal $4.1 million;
Compliance $3.8 million;
Infrastructure $2.4 million;
Marketing $1.4 million;
Bounty $1.2 million;
Sponsorship $400,000;
Media $350,000;
Regulation $200,000;
Activities $10 $35.6 million; total cost is $35.6 million. This does not include the exchange launch expenses, which fortunately we do not need to do this year.”
