The RadiumBlock team, an infrastructure provider for the Polkadot/Substrate community, is seeking reimbursement for the provision of public RPC services for the Polkadot networks for Q4 2022 and Q1 2023. We are committed to the DotSama ecosystem and we are investing significant capital upfront, believing we can provide a reliable and secure service to the community at a fixed and reasonable cost. We would like to emphasise that we do not collect any user data. We only track average rpc requests rate, computation and bandwidth use. We are proud to operate one the highest performance RPC service in polkadot ecosystem as measured by CompareNodes.

Service Usage Summary

For Q4 2022 (Oct-Dec)

• Our Polkadot RPC nodes have served an average of 21 million responses per day
• Our Statemint RPC nodes have served an average of 450k responses per day

For Q1 2023 (Jan-March)

• Our Polkadot RPC nodes have served an average of 11 million responses per day
• Our Statemint RPC nodes have served an average of 315k responses per day

Major updates

• Converted our RPC deployment to a Hybrid On-Prem + Cloud(AWS) computing
  • In future we will switch to using AWS only as a backup.
• Expanded Polkadot endpoint to 12 Edge locations including South America, Africa and India
  • The full list is: Santiago, Johannesburg, Chicago, Silicon Valley, Frankfurt, Madrid, London, Hong Kong, Mumbai, Singapore, Tokyo, Sydney.
• Switching from Q2 2023 to a reduced and fixed cost model (~$25k) per quarter
  • This is part of our continued effort to reduce cost to the treasury and to make the cost predictable and bounded
  • We are passing on the cost benefits of our hybrid computing to the community

We continue to engage in the ecosystem as an infrastructure provider for other para chains too for RPC and node services. Our full proposal is posted here.
