Short description: Ongoing & advanced costs for the running of high performance, scalable, and reliable public infrastructure in Q3 and Q4 of 2024  for Polkadex Solochain.

# Why are Public RPC Services Needed for Polkadex
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 Polkadex 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 polkadex nodes  to any cloud of your choosing. 

# OnFinality’s RPC Service
As Polkadot’s largest and most cost efficient infrastructure provider, this proposal will support OnFinality’s free public API services for the Polkadex community. 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.

## Performance/Reliability
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 Hong Kong) 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.

## Cost Optimisation & Decentralisation
From January 2024, OnFinality’s Polkadex Solochain has run entirely on OnFinality Cloud - North Virginia, our own private hardware and self service cloud
This allows us to support the decentralisation of the Polkadex Network while delivering exceptional performance at a competitive pricing.

# Service Details

In the last 6 months (2024-01-01 and 2024-06-30) our Polkadex API service has:
- Served a total of 4 Billion (4,066,299,768) responses
- Accumulated over 4,000 GB of data egress 
- The highest daily total was 138 million responses (138,375,377)  in a single 24 hour period
- Our rolling 7 day average at the end of this period was over 36 million responses each day
- All time totals for Polkadex is 5.2 Billion (5,210,778,101) since March, 2022

At the end of this period the 90 day uptime for Polkadex was 99.77%. You can always see live data of our API service on our public status page.

# Costings
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 Polkadex for all of Q2 and Q3 2024. By paying 6 months up-front we will apply a 15% discount to our services. An additional 10% discount has been applied for not meeting the 99.9% Uptime SLA target over the past 3 months.

The total combined running cost is **USD $6,100.11** after discounts. 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. The base price change from the previous period is due to the storage per node increasing from 133GB in January 2024 to 299GB.
