Future of RPC node providers

RPC nodes are used to connect to the Interlay and Kintsugi networks. Dwellir and OnFinality are both providers in the Dotsama space to provide such services (think Infura for Dotsama).

It's generally a good idea to have two providers for redundancy in case one provider might go offline. However, the treasury should also not overspend on RPC node provision.

Current status

Currently, there are the following options for RPC nodes:

  • Kintsugi/Interlay Labs. These are not invoiced against the treasury but the Interlay team operates these.
  • OnFinality. OnFinality operates nodes for Kintsugi and Interlay networks. The currently charge the Kintsugi treasury only for the RPC node provision.
  • Dwellir. Dwllir has recently set up Kintsugi and Interlay nodes as well. They are not charging the treasury but opened a discussion post on the Interlay forum to operate nodes in the future.

Update 20 June 2023

James from OnFinality here

There is some detail missing here from this proposal that may change the outcome. We've recently reduced our service price for Interlay and Kintsugi to be able to provide a fixed price service for Interlay and Kintsugi for $4,000 per quarter (total across both).

OnFinality for a long time has been the sole commercial operator of Interlay and Kintsugi nodes, as a result, we've received huge traffic to our Interlay and Kintsugi nodes. From inception of the Kintsugi API Service on 2023-10-12 until 2023-05-31 our Kintsugi and Interlay API service has:

  • Served a combined total of over 2.5 billion (2,531,891,335) requests
  • Accumulated almost 9 TB of data egress
  • The highest daily responses in a single 24 hour period for Interlay occurred on the 21st of December 2022 with 92,949,041 (almost 93 million responses)
  • The highest daily responses in a single 24 hour period for Kintsugi occurred on the 20th of December 2022 with 66,337,717 (over 66 million responses)
  • At the end of this period the 90 day combined uptime for Interlay and Kintsugi was 99.99%
  • Raw Data can be found here.

As you can see, OnFinality is designed to massively scale to handle bursty traffic with almost zero downtime. Our previous advice from the Interlay governance body was to manage a public service where pure uptime and performance were the main considerations, our 99.99% uptime means that OnFinality was down for less than 14 minutes in the entirety of the last quarter shows that we have clearly achieved this, despite bursty traffic. That advice has since changed and we're pleased to be able to show the results of these cost controls with this fixed price service of $4,000 per calendar quarter.

Additionally, we now have better analytics on where our customers are making requests from (you can see some aggregated data here, so we will also move our nodes to better serve these users in the United States, Germany, and the Netherlands.


Ben from Dwellir.

When we take a closer look at the data egress figures, we find ourselves in a position to provide a more refined price evaluation. The breakdown for this quarter is as follows:

Interlay: $663 per quarter
Kintsugi: $1621 per quarter
Combined Total : $2284 per quarter

These numbers provide us with a clearer picture of the costs involved and allow for a more accurate budget projection.

Secondly, I'd like to highlight Dwellir's impressive performance over the past year. We've expanded our utility from 1 billion RPC requests per month to an astounding 30 billion RPC requests this year alone, with virtually zero downtime. This represents a significant increase in the scale and reliability of our operations.

Looking ahead, Dwellir has ambitious plans to launch an API developer service before the end of 2023. This is part of our ongoing commitment to innovation and supporting our user community.

Finally, I want to assure everyone that Dwellir remains steadfast in our commitment to the decentralized vision of owning and operating bare metal machines. This approach significantly reduces the risk of downtime from third-party providers such as AWS. It's a critical part of our strategy to ensure consistent and reliable service to our users.

We appreciate your ongoing support and look forward to continuing to deliver high-quality services that meet your needs.
