Unit Network


Polkadot's parachains are specialised blockchains that run in parallel to the main network, offering shared security, scalability, and customisability benefits for a range of use cases.


Polkadot is a blockchain platform that was created to address the challenges of interoperability, scalability, and governance in the blockchain space. It was founded by Gavin Wood, a co-founder of Ethereum, and was developed by the Web3 Foundation and Parity Technologies.
Polkadot's unique architecture allows it to connect different blockchains and networks, enabling them to communicate and exchange data with one another. This interoperability feature solves a major problem in the blockchain space, as it allows for the creation of a decentralized, multi-chain ecosystem that can support a wide range of use cases.
In addition to interoperability, Polkadot also addresses scalability issues through a sharding mechanism that divides the network into smaller pieces, each of which can process transactions independently. This allows Polkadot to process a much higher number of transactions per second than traditional blockchains.
Polkadot's governance model is designed to be highly decentralized and transparent, with stakeholders having a say in the decision-making process. This ensures that the network remains secure, stable, and adaptable as it continues to evolve over time.
Polkadot is likely the superior layer one protocol because of its unique features and ability to solve some of the most pressing challenges facing the blockchain space. Its focus on interoperability, scalability, and governance make it an attractive platform for developers, enterprises, and users alike, and its ongoing development and evolution promise to deliver even more value and innovation in the years to come.


Polkadot unites and secures a growing ecosystem of specialised blockchains called Parachains. Apps and services on Polkadot can securely communicate across chains, forming the basis for a truly interoperable decentralised web.
  • True interoperability
    Polkadot enables cross-blockchain transfers of any type of data or asset, not just tokens. Connecting to Polkadot gives you the ability to interoperate with a wide variety of blockchains in the Polkadot network.
  • Economic & transactional scalability
    Polkadot provides unprecedented economic scalability by enabling a common set of validators to secure multiple blockchains. Polkadot provides transactional scalability by spreading transactions across multiple parallel blockchains.
  • Easy blockchain innovation
    Create a custom blockchain in minutes using the Substrate framework. Connect your chain to Polkadot and get interoperability and security from day one. This ease of development helps Polkadot's network grow.
  • High energy efficiency
    Polkadot consumes a small fraction of the energy used by conventional blockchains thanks to its next-generation nominated proof-of-stake (NPoS) model. Using the equivalent of ~6.6 US households worth of energy per year, Polkadot has the lowest carbon footprint among proof-of-stake protocols analysed in recent research.
  • Security for everyone
    Polkadot's novel data availability and validity scheme allows chains to interact with each other in a meaningful way. Chains remain independent in their governance, but united in their security.
  • User-driven governance
    Polkadot has a sophisticated governance system where all stakeholders have a voice. Network upgrades are coordinated on-chain and enacted autonomously and without forking the network, ensuring that Polkadot’s development remains future-proof and community-driven.
