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.
