Polkadot: Building a secure, interoperable and secure network protocol oriented towards Web 3.0


As part of Polkadot’s design, external networks, as well as custom Layer 1 “parachaines”, can interface with each other, forming an interconnected network of blockchains. The network is based on an environmentally friendly proof of stake consensus mechanism. It is therefore possible to create inter-chain registers and perform inter-chain calculations. Polkadot can therefore be used to transmit data through public and private blockchains.

A network of heterogeneous blockchains called parachains and parathreads are brought together by Polkadot to create a single network. There is a Polkadot Relay Chain building foundation that connects and secures all of these chains together and with the help of bridges they can also connect to external networks.

With its shared security, consensus and cross-chain interoperability, Polkadot’s Relay Chain is at the heart. In contrast, Parachains are sovereign chains that can issue their tokens and improve the functionality of their blockchains for certain use cases. Parathreads are pay-per-use thread systems similar to parachains. They are more profitable for blockchains that do not require constant connections. To connect and interact with other networks like Ethereum and Bitcoin, parachains and parathreads can use bridges.

Parity Technologies’ experiences in building Ethereum, Bitcoin, and enterprise blockchain led to the development of Substrate, Polkadot’s relay chain. As a result, Polkadot’s state machine is written in WebAssembly (Wasm), an extremely fast virtual environment. Several important companies have contributed to the development of Wasm. These companies include Google, Apple, Microsoft, and Mozilla.
Libp2p, which is a cross-platform network framework, is leveraged by Polkadot Networking to support versatile peer-to-peer applications. As a standard for future decentralized applications, libp2p is responsible for discovery and peer-to-peer communication in the Polkadot ecosystem, which is based on the Polkadot protocol. Polkadot is accessible to a wide range of developers because its runtime environment is coded in Golang, C ++, and Rust.

Unlike the single transaction methodology currently in use, the Polkadot technique supports multi-parallel transactions. Specialized blockchains connected to the Polkadot network are called Parachains. Because they are designed for specific use cases, they will be able to regulate their governance. Parachain interactions are managed in parallel, allowing extremely scalable systems. This allows a greater number of transactions to be carried out at the same time.

When it comes to blockchain, using its breakthrough technology, Polkadot tackles many of the issues that have hampered the technology so far. Whether using a proof of work or proof of stake method, blockchains compete for the resources needed to protect their networks, and blockchains are easily attacked until they build a community. large enough to support their network. For example, Polkadot allows blockchains to pool their security, which means that the collective security of blockchains is pooled and applied to everyone. By using Polkadot, blockchain engineers can protect their blockchain from the start, rather than having to wait for the project to end.


With transparent on-chain governance mechanisms designed to enable the responsible and binding process to resolve disputes and network upgrades, coupled with a trust consensus algorithm. Polkadot paves the way for more secure and resilient networks.
