beamprivacy/testnet-node repository overview

⁠What is Beam?

Beam is privacy-centric cryptocurrency based on the Mimblewimble Protocol. Beam transactions are private by default, and storing the entire transaction history is not necessary for blockchain validation. This ultimately reduces the blockchain size and improves scalability. Beam supports many transaction types such as escrow transactions, time-locked transactions and atomic swaps. Our roadmap includes dozens of features and is constantly evolving. We are striving to make Beam an ultimate Store-of-Value coin.

⁠The technology

Beam is based on Mimblewimble — an elegant protocol released by an anonymous developer in 2016. Named after a tongue-tying spell from the Harry Potter saga, Mimblewimble uses Pedersen Commitment scheme for full anonymity and zero-knowledge range proofs to ensure the validity of transaction amounts.

To enhance privacy and reduce the blockchain size, Mimblewimble merges all intermediate outputs within a single block and across multiple blocks, thus only storing the current UTXO state and making the blockchain size an order of magnitude smaller than in other leading currencies.

Beam implemented Mimblewimble from scratch using C++.

Beam blocks are mined using memory-hard Equihash Proof-of-Work algorithm. The block time is 1 minute on average.
