**This proposal was originally lodged at the beginning of 2024 however it failed due to no votes. This has only recently come to our attention so we are re-lodging the proposal now.
Report & Proposal: High Performance Public Infrastructure (Q1 & Q2, 2024)
Kintsugi Proponent: a3byawr54JPxf1RpvnbLZPkZN2Q9Ry7gg5CXiqcvEtgPWvQM8
Date: 17th April 2024
Total Requested KINT: KINT 3,321.2681
Short description: Ongoing & advanced costs for the running of high performance, scalable, and reliable public infrastructure in Q1 and Q2 of 2024 for Kintsugi.

Setting up blockchain infrastructure is difficult, time consuming, and expensive:
It requires a level of server development expertise that many do not have
It's costly to run a full node nearly continuously, especially when your dApp's traffic is low and inconsistent.
Running production level infrastructure is especially tricky. You need to autoscale quickly to handle bursty traffic, and you want to provide services in different regions around the world to provide low latency services - all of this is incredibly costly, but comes with significant economies of scale for a provider.
DevOps requires constant attention - time that would be better spent elsewhere building.
A shared node API service helps mitigate these barriers of entry to trying accessing a new protocol by reducing all these costs to near zero. We manage all the nodes for our users and distribute them across the world (with intelligent routing) to achieve global scalability from day 1, we monitor each node and ensure that they meet certain service levels, and we have the expertise and scale to handle production workloads and high peak traffic.
In summary, we try to reduce the pain of getting started on Kintsugi Network and minimise the costs of accessing secure nodes while traffic from your dApp is low. When you grow, you can continue to use our shared API service, or we also provide access to one click deploy dedicated Kintsugi nodes to any cloud of your choosing.
As Polkadot's largest and most cost efficient infrastructure provider, we provide scalable free public API services for Kintsugi. Since our inception in November 2020 we have a long track record focussing on three key areas; performance/reliability, providing more value from our Ultimate API service, and cost optimisation.
OnFinality is operationally striving for a minimum of 99.99% reliability, which means less than an hour of downtime each year. We are the only RPC provider to guarantee this with actual financial penalties (see appendix A). We proudly display and share our 90 day uptime statistics for each network publicly here.
We have invested hugely into a team dedicated to optimising our application gateway and caching layer to ensure that we provide the fastest possible service for our customers. We run clusters in 5 different regions (North Virginia, Frankfurt, Tokyo, Singapore, and Australia) and across 4 different cloud providers (AWS, GCP, Alicloud, and our own dedicated hardware) to ensure that we are fault tolerant to any single region or cloud provider ceasing service.
For customers that do sign up for API keys, we've been adding more and more features to provide a better experience. Geolocation insights provide statistics about where in the world communities are to help influence decisions around where to expand infrastructure and to view the effectiveness of regional BD initiatives.
OnFinality is the only provider with Trace API support, a huge and essential enhancement allowing unprecedented visibility for dApp builders. Trace API captures and records vital information otherwise not available through regular RPC methods and extrinsics (such as complete XCM transfer records and complete list of balance changes). These APIs are essential in order for developers like Polkaholic and Parity's data team to parse and understand XCM transactions.
We've recently added support for 14 more Polkadot parachains as well as Osmosis, Evmos, Harmony, Arbitrum, Optimism, Fuse, DFK Chain, Celo, and Klaytn from outside the ecosystem. With over 100 supported networks, OnFinality is now the largest RPC provider worldwide (in terms of networks supported), and our ongoing expansion helps to bring more and more developers into the Polkadot ecosystem.
OnFinality is very conscious about providing a strong level of support for Kintsugi at an extremely competitive price.
That's why our Kintsugi RPC Service will run entirely on OnFinality Cloud - North Virginia, our own private hardware and self service Cloud
This allows us to support the decentralisation of the Interlay Network while delivering exceptional performance at a competitive price.
In the last 5 months (2023-07-01 and 2023-11-31) our Kintsugi API service has:
Served a total of 874 million (873,611,098) responses
Accumulated over 2,704 GB of data egress
The highest daily total was 66 million responses (66,337,717) in a single 24 hour period
Our rolling 7 day average at the end of this period was over 300,000 responses each day
All time totals for Kintsugi is 1,816,134,571 (1.8 Billion) since October, 2021
At the end of this period the 90 day uptime for Kintsugi was 99.98%. You can always see live data of our API service on our public status page.
We are using a fixed price to allow us to bill in advance and to simplify the administration of this proposal, as well as provide cost clarity to both parties. This proposal includes combined running costs for our infrastructure for Kintsugi for all of Q1 and Q2. By paying 6 months up-front we will apply a 15% discount to our services.
The total combined running cost is USD $3,162.00. This is all inclusive of capital and operating expenses, administration time from OnFinality DevOps, onboarding costs, backup costs, and all other monitoring and right-sizing by our team.
