The short answer

A network of specialized chains that share one security layer. Polkadot lets each project run its own chain tuned to its needs while renting security from the relay chain instead of bootstrapping validators.

Block explorers

An explorer lets you verify any transaction, address or contract on this network yourself. Learning to read one is the fastest way to stop taking anyone's word for anything.

Wallets that support it

What to be aware of

  • Validator concentration varies widely between layer 1s and is worth checking rather than assuming.
  • Newer chains have shorter track records under real adversarial pressure.
  • Crypto assets are volatile. Drawdowns of seventy percent or more have happened on every network in this list, including the largest.
  • Sending to an address on the wrong network can lose funds permanently. Always send a small test amount first.
