What is Beam?

Beam is a 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. Ultimately, Beam is a store-of-value coin.

Beam Features

Stronger privacy controls are at the top of the list of Beam’s features. It’s believed that other privacy coins have defined a privacy model that only makes transactions private when specifically requested rather than adding privacy by default.

Beam reverses this and makes every transaction private by default. This means users are the only ones capable of determining what information is made publicly available, and keeps complete control of personal data in the hands of the users.

Beam has also introduced the concepts of confidential transactions and confidential assets as an added privacy value feature. This feature will allow for the creation of new digital asset types such as debt instruments, real estate assets, new currencies, all of which can easily be exchanged privately on the Beam platform.

While other blockchains have been struggling with scalability issues, Beam believes they’ve solved the issue by keeping a clean and compact blockchain. Transactions have been designed to avoid bloating, through the use of Mimblewimble protocol to prune old data that’s become irrelevant to current transaction processing needs.

Not only will this reduce bloat it will also reduce computational overhead demands, thus improving network scalability. Beam has been designed to be capable of supporting a variety of transaction types using its Scriptless Script technology. Besides simple value transfers, Beam also supports time-locked transfers, atomic swaps, and escrow payments.

Privacy will remain the top priority, but this feature also complies with existing regulations through the support of unforgeable digital wallet signatures. This will allow authorized auditors to see the full list of transactions and any relevant documentation.


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 less than 1 minute on average.
