Building Instructions

Things that make BEAM special include:

  • Users have complete control over privacy - a user decides which information will be available and to which parties, having complete control over his personal data in accordance to his will and applicable laws.
  • Confidentiality without penalty - in BEAM confidential transactions do not cause bloating of the blockchain, avoiding excessive computational overhead or penalty on performance or scalability while completely concealing the transaction value.
  • No trusted setup required
  • Blocks are mined using Equihash Proof-of-Work algorithm.
  • Limited emission using periodic halving.
  • No addresses are stored in the blockchain - no information whatsoever about either the sender or the receiver of a transaction is stored in the blockchain.
  • Superior scalability through compact blockchain size - using the “cut-through” feature of Mimblewimble makes the BEAM blockchain orders of magnitude smaller than any other blockchain implementation.
  • BEAM supports many transaction types such as escrow transactions, time locked transactions, atomic swaps and more.
  • No premine. No ICO. Backed by a treasury, emitted from every block during the first five years.
  • Implemented from scratch in C++.
