“The whole is greater than the sum of its parts”

Proposal for RPC Services to Basilisk Mainnet

20th March 2023




UnitedBloc is made up of 13 members from the Kusama and Polkadot ecosystem. Every member provides top-quality services to the numerous communities in which we operate. Our members are involved in over 75 blockchains, with hands-on experience supporting Kusama, Polkadot, and parachains.

We are proposing to provide RPC services for the Basilisk parachain on the Kusama relay chain. Our services will include 2 RPC nodes with one in Asia and a second in Europe, a 24x7 monitoring dashboard, and centralized collator logs. Our bare-metal server setup provides improved performance, consistency, and value compared to virtual servers or other delivery methods, and combined with experience and knowledge in business and technology, we are the perfect match to support the Basilisk network.

Assumptions and Caveats:

  1. Term Commencement: 14 days of agreement between UnitedBloc and Basilisk network.
  2. Tip payment proposals must be approved and disbursed to UnitedBloc within seven days after 90 days from the handover of service to avoid any service disruptions.
  3. Penalties/Slashing: UnitedBloc agrees to penalties in the event of failure to maintain a 99.9% availability or other agreed measure of failure to perform, proportional to the level of performance failure, and not exceeding 50% of the monthly or full-term charge.
  4. Bedding in Period: The first month of service will be considered a "bedding in" period where adjustments may be made, and the load will be monitored. Data on usage will be available to the Basilisk teams via the Grafana portal.
  5. Rate Limiting: Services are rate limited to prevent DoS/DDoS attacks. End users of the services with heavy load requirements can be directed by Basilisk to UnitedBloc's dedicated RPC service. This ensures that the service is available to all Basilisk users, and no one greedy dApp can take down the service for other consumers.
  6. Right to Move Services: At any time during the delivery of services, UnitedBloc may move or the Basilisk council can request to move the location of services to better support Basilisk parachain. Any changes will be reviewed beforehand with Basilisk teams for approval.
  7. UnitedBloc may change the monitoring and logs collector technologies as determined at the sole discretion of UnitedBloc. All changes will be reviewed with parachain teams with the option to maintain existing setup until the end of service term.
  8. Deployments outside of North America and Europe subject to additional charges.
  9. This proposal is for deployment in Europe and Asia and users accessing RPC services outside of Europe and Asia may experience degraded performance due to latency.
  10. In the event of node failure, services will roll over to the other geo-location, which may result in increased latency and degradation of service until such time full service is restored.

To make clear on the above proposal, the collator logs and collator data will not be included because we are only proposing to provide the stated RPC services. Thanks!
