Description

What is the NEAR blockchain?

  • built to be simple, secure and scalable.
  • Low cost. High speed. Effortless scale.
  • <0.01USD Transaction Cost
  • 18M+ Active Accounts
  • 400K Daily Transactions
  • ~2.4s Time to Finality
  • Contracts, DAOs, dapps, funding
  • Layer 1 blockchain

    not dependent on other chains.

uses a unique scaling mechanism

  • Nightshade sharding
  • Scales infinitely
  • resists short-term usage spikes

Proof of stake

  • More efficient than Bitcoin and Ethereum

web-based wallet

  • no need for users to install programs or browser extensions
  • makes it especially easy to onboard new users (e.g. through named accounts)

Certified carbon neutral

  • consumes in a year the same energy bitcoin consumes in 3 minutes

Interoperable with Ethereum

  • using Rainbow Bridge
