Proponent: 42PDjUSugisVhhNQg453fkDwLmg9QMzeWe9huR817xt7c3DW

Date: 22nd August 2024

Total Requested PHA: $20,196 USD or 194,192.307 PHA

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

Why are Public RPC Services Needed for Phala

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.

Background on our RPC Service

As Polkadot's largest and most cost efficient infrastructure provider, we provide scalable free public API services for Phala. 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.

Service Details

In the last 6 months (2024-01-01 and 2024-05-31) our Khala API Service has

• Served a total of 376 Million (376,107,012) responses
• Accumulated over 3,000 GB of data egress
• The highest daily total was 16  million responses (16,633,185)  in a single 24 hour period
• All time totals for Khala is 10,802,293,451 (10.8 Billion) since June, 2021
• Phala served over 158 million API responses in the period
• All time totals for Phala is 547 million (547,938,607)

At the end of this period the 90 day uptime was 99.50% for Phala and 99.53% for Khala. 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 Phala and Khala 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 $20,196. 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.
