Sub0 is coming to Lisbon! Join the Polkadot developer conference, November 28th-29th

The multichain vision for Web3 starts here.

Polkadot unites and secures a growing ecosystem of specialized blockchains called parachains. Apps and services on Polkadot can securely communicate across chains, forming the basis for a truly interoperable decentralized 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 analyzed 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.

Powering the Polkadot network

The DOT token serves three distinct purposes:
governance over the network, staking and bonding.

Governance

Polkadot token holders have complete control over the protocol. All privileges, which on other platforms are exclusive to miners, will be given to the Relay Chain participants (DOT holders), including managing exceptional events such as protocol upgrades and fixes.

Staking

Game theory incentivizes token holders to behave in honest ways. Good actors are rewarded by this mechanism whilst bad actors will lose their stake in the network. This ensures the network stays secure.

Bonding

New parachains are added by bonding tokens. Outdated or non-useful parachains are removed by removing bonded tokens. This is a form of proof of stake.
