OnFinality is a blockchain infrastructure platform that saves web3 builders time and makes their lives easier. We deliver easy-to-use, reliable and scalable API endpoints for the biggest blockchain networks and empower developers to automatically test, deploy, scale and monitor their own blockchain nodes in minutes.
We also support Layer-1 ecosystems such as Avalanche and Cosmos, and are continuously expanding these mission-critical services to other ecosystems to help developers build the decentralised future, faster!
In this OnFinality Layer-1 Introduction series, we gather resources that may be useful for builders using OnFinality infrastructure to get started in Polkadot.
Our Enhanced API Service has been serving over 1 Billion JSON RPC requests to its public API service every day across Polkadot and its 99.9% uptime is why most Polkadot parachain teams are relying on it.
“We are proud and humbled that every team trusts OnFinality to be their launch partner. We’ve worked hard over the years to build our relationships with the best teams in Polkadot and we see a long future ahead. From our enhanced API service to our one-click dedicated node deployment tools, OnFinality is dedicated to providing critical infrastructure to the best blockchain teams in the world so they can focus on their core business.”
— Sam Zou, Founder and CEO at OnFinality
What Is Polkadot?
Polkadot is an open source blockchain platform and cryptocurrency. It provides interconnectivity and interoperability between blockchains, by enabling independent chains to securely exchange messages and perform transactions with each other without a trusted third-party. This allows for cross-chain transfers of data or assets, between different blockchains, and for cross-chain DApps (decentralised applications) to be built using the Polkadot Network. — Wikipedia
Polkadot is the flagship project by Web3 Foundation, a Swiss Foundation founded to facilitate a fully functional and user-friendly decentralised web. The Web3 Foundation is partnering with best-in-class entities to build Polkadot and foster development of the services and applications that will run on it. — Polkadot
Watch this video by two highly respected Polkadot veterans Bill Laboon, Head of Education and Grants at Web3 Foundation, and Dan Reecer, Chief Growth Officer at Acala and Karura, to understand everything you need to know about how blockchain came about and how Polkadot is going to change the world.
Key Concepts About Polkadot
Before you embark on your journey to change the world on Polkadot, here are some key concepts that should help you navigate the DOT universe with clarity.
Parachains are a unique aspect of the Polkadot ecosystem whereby different blockchains for different use cases can be created and then connected to the main ‘relay chain’ of the Polkadot network.
Proof-of-Stake (PoS) vs Nominated Proof-of-Stake (NPoS)
A method of selecting participation in a consensus system, in which participants are chosen based on how many tokens they have at stake (at risk of loss due to misbehaviour). Normally, Proof-of-Stake systems limit the number of participants. — Polkadot Wiki
Polkadot introduces a variant of PoS called Nominated Proof-of-Stake, with design choices based on first principles and having security, fair representation and satisfaction of users, and efficiency as driving goals.
