Polkadot is a blockchain network built to enable Web3 and decentralized internet.
What Makes Polkadot Unique?
Polkadot is a sharded multichain network, meaning it can process many transactions on several chains in parallel (“parachains”). This parallel processing power improves scalability.
Custom blockchains are quick and easy to develop using the Substrate framework and Substrate blockchains are designed to be easy to connect to Polkadot's network. The network is also highly flexible and adaptive, allowing the sharing of information and functionality between participants. Polkadot can be automatically upgraded without the need for a fork in order to implement new features or remove bugs.
The network has a highly sophisticated user-driven governance system where all token holders have a vote in how the network is run. Teams can customize their own blockchain’s governance on Polkadot based on their needs and evolving conditions. Nominators, validators, and collators all fulfil various duties to help secure and maintain the network and eradicate bad behavior.
How Is the Polkadot Network Secured?
The network uses an NPoS (nominated proof-of-stake) mechanism with validators and nominators.Nominators back validators with their tokens. These staked tokens maximize chain security by making it prohibitively expensive to misbehave.
Validators are staked on the Relay Chain and confirm transactions coming from the different parachains. This unique validity scheme enables chains to interact with each other securely under the same rules, yet remain independently governed.
