4. Polkadot (DOT)
Polkadot is a unique proof-of-stake cryptocurrency designed to provide interoperability between other blockchains.
Its protocol aims to connect blockchains, as well as oracles, and allow multiple systems to work together in the same environment.
The star component of Polkadot is its relay chain, which allows for the interoperability of multiple networks.
It also allows parallel parachains or blockchains to use their own native commemoratives in specific use cases.
The difference between Dapple and Ethereum is that many developers can not only create decentralized applications on Dapple, but also create their own blockchains using the existing security of the Dapple chain.
Like Ethereum, many developers can create new blockchains, but they need to create their own security measures, which will make new and smaller projects vulnerable to attacks, because the larger the blockchain, the more secure it is.
This concept at Dapple is known as shared security.
It also makes other changes, including removing the insulated Witness protocol that impacts block space.
