Polkadot is a scalable blockchain that ensures network interoperability and a secure decentralized open-source protocol for connecting different chains (multi-chain framework).
It was one of the most innovative projects for stakeholders because it tried to solve two big problems: scalability and security.
Its key strengths are:
- fill the lack of interoperability;
- reduce the high cost of gas fees and shardings;
- encourage the mass adoption of blockchain.
