#dot #TrendingTopic #polka There are thousands of cryptocurrencies across the ecosystem, a vast majority of which can’t communicate with each other. For example, users can’t send their Dogecoin over Chainlink for instance, or vice versa. Polkadot aims to fix that by building a framework that interconnects blockchains, even if each chain performs different functions to one another.
At the center of Polkadot sits the “relay chain,” a central blockchain that connects all other participating blockchains together. The relay chain processes all transactions taking place in the ecosystem at the same time, with the goal of improving scalability.
User-created blockchains that hook into the relay chain are known as “parachains.” By allowing blockchains to communicate with its platform, Polkadot is able to connect many blockchains in a way that wasn’t possible before.
