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

# Why are Public RPC Services Needed for Polkadex Parachain
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. 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 infrastructure 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 & Decentralistion
OnFinality’s Polkadex Parachain API is running 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 price.

# Service Details
Our Polkadex Parachain API service commenced on 16th August 2023. Over the past 6 months (From 2024-01-01 to 2024-06-30) it has
- Served a total of 1.6 Billion (1,683,882,678) responses
- The highest daily total was 54 Million responses (54,727,292)  in a single 24 hour period
- Our rolling 7 day average at the end of this period was over 31 Million (31,797,141) responses each day

At the end of June the uptime over the past 90 days was  99.65%. 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 Q3 and Q4 2024. A 15% discount has been applied for pre-paying 6 months of service in advance.

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.

- **Problem Statement:** Setting up and maintaining blockchain infrastructure for Polkadex Parachain is challenging and costly for many due to the expertise required, continuous node operation expenses, and the need for global scalability.
  
- **Significance:** OnFinality's RPC service aims to reduce barriers by managing nodes globally, ensuring reliability, and offering cost-efficient solutions, enhancing accessibility to Polkadex while minimizing initial costs.
  
- **Proposed Solution:** OnFinality proposes to provide free public API services for the Polkadex community, guaranteeing high performance, reliability, and cost optimization through their infrastructure across multiple regions and cloud providers.
  
- **Expected Outcomes:** By pre-paying for 6 months of service at a 15% discount, the proposal requests USD $3,162.00 to cover all expenses related to running Polkadex infrastructure for Q3 and Q4 2024, aiming to maintain high uptime, scalability, and cost-effectiveness for users.
