With so many blockchain protocols under development, it’s critical that we understand their purpose, unique selling proposition, and the challenges they tackle.
Interoperability is one of the most significant difficulties that blockchains face. Because of their segregated nature, blockchains are unable to communicate with one another.
To further appreciate the topic of interoperability, consider the following scenario: If you’re a gamer, you’re probably aware that you can’t play an XBOX game on a Playstation and vice versa. A game must be built in two separate iterations for the XBOX and Playstation in order to be compatible between the two consoles.
Similarly, migrating a solution established on one blockchain platform to another presents significant hurdles. This lack of connection and communication among blockchains is seen by the blockchain community as a fundamental structural problem impeding the technology’s wider adoption. In fact, this issue has posed significant roadblocks to the creation of a truly decentralized ecosystem embracing multiple blockchains.
Polkadot, often known as the “blockchain superhighway,” addresses this issue by providing greater blockchain interoperability and connecting the gaps in the huge blockchain network.
Polkadot is a kind of all-in-one gaming system that can read both PS3 and Xbox 360 titles. Gamers would clearly choose to utilize this console over others because it would allow them to play their favorite games without having to worry about the device’s compatibility.
What exactly is Polkadot?
Polkadot is a next-generation blockchain protocol that can connect a network of purpose-built blockchains, allowing them to function together effortlessly at scale. Polkadot enables data sharing between different blockchains, which opens the door to a wide range of real-world applications.
While blockchains have shown their potential in a variety of domains, including online decentralization, banking, governance, identity management, and asset tracking, design flaws in practically all prior and most existing systems may stymie their general adoption. Polkadot’s design has a number of advantages over existing and legacy networks, including cross-chain composability, transparent governance, upgradeability, scalability, and heterogeneous sharding.
The architecture of Polkadot
Polkadot creates a coherent network by combining multiple diverse blockchain shards or parachains. These chains are attached to the Polkadot Relay Chain and are fastened by it. With the use of bridges, they can also communicate with external networks. Based on the roles they play, here are the most critical Polkadot network components:
Parachain consensus components include the following:
Polkadot’s design revolves around the relay chain, which is responsible for the network’s consensus, cross-chain interoperability, and security.
Parachains: These are self-contained blockchains with the ability to tailor their functionality to specific use cases. Parachains can lease a slot or pay as they go to stay connected to the Relay Chain. Parachains have tokens of their own.
Bridges: These unique blockchains enable communication between Polkadot shards and external networks like Bitcoin and Ethereum.
Nominators: They ensure the security of the relay chain by selecting reliable validators and staking DOTs.
Validators: Validators safeguard the relay chain’s security by collaborating with other validators, validating proofs from collators, and staking DOTs.
Collators: are responsible for the upkeep of shards by gathering shard transactions from users and producing proofs for validators.
Fishermen: They are largely responsible for network oversight and monitoring, as well as bringing any bad conduct to the attention of validators. Any full node or collator in the parachain can act as a fisherman.
Polkadot Governance components include the following:
Members of the Council: They are elected to represent passive stakeholders and to undertake two crucial governance functions. To begin, referenda should be proposed. Second, to veto referendums that are harmful or dangerous.
The Technical Committee is made up of the technical teams in charge of constructing Polkadot. The committee can propose emergency referenda with the council members.
