Beam (or the "Project") is a scalable, privacy-oriented cryptocurrency based on the MimbleWimble protocol which conceals the values and metadata of transactions. Using the MimbleWimble protocol, Beam is able to enhance privacy and fungibility, while reducing blockchain bloating and improving scalability.

Key Features of Beam

  • All transactions are private by default
  • Compact blockchain
  • Wallet app for mobile and desktop
  • Atomic Swaps, Confidential Assets, Payment Channels and Opt-In Auditability in the near future

Beam’s mission is to let users have complete control over their money. The team is building a new blockchain to provide confidential, decentralized and usable store of value and means of payment, as well as a strong self-governed community to further develop and support it.

BEAM Emission

BEAM is designed to be a deflationary coin with capped supply, halving every four years and stopping emission altogether after 133 years.

BEAM emission schedule is largely inspired by Bitcoin’s. The main differences are that there are 10 times more blocks and that BEAM’s first-year emission is 100 BEAM coins per block. The first halving occurs after 1 year, and then halvings occur every 4 years, 33 times in total.

The emission is of BEAM is denominated in Groth, the smallest unit of BEAM. One BEAM contains 100,000,000 Groth.

In the first 5 years, BEAM emission is split between Mining Rewards and the Token Treasury.

Mining Rewards: In the first year, Mining Rewards will be 80 coins per block. In years 2–5, Mining Rewards will be 40 coins per block. In year 6, Mining Rewards will be reduced to 25 coins, and then halving will occur every 4 years until year 129. After year 133, BEAM emission will stop.

Token Treasury: In the first year, 20 BEAM coins per block are emitted to the Token Treasury, and in the second to fifth year, the Treasury will receive 10 coins per block. The Token Treasury will be used to repay investors (Private Sale 1, 2, and 3), incentivize the Team and Advisors, and to support the Beam Foundation.

The emission curve of BEAM is shown below:

Token Governance & Use of Funds

As of writing, Beam has not yet started using the Beam Foundation tokens. The Beam team is currently setting up the Beam Foundation.

The private keys to the Team and Foundation wallets are held in secured vaults with 24/7 security. Opening the vault requires physical keys from two of Beam's core team members.

BEAM Token Release Schedule

The following chart represents the number and breakdown of all BEAM that are to be released into circulation on a monthly basis.

BEAM Token Overview & Use Cases

The BEAM token currently has two forms of utility:

  • Medium of exchange with full anonymity
  • Confidential store of value

Beam is based on MimbleWimble, a protocol that allows full confidentiality of blockchain transactions without compromising scalability. Similar to Bitcoin, the MimbleWimble blockchain is based on the Unspent Transaction Ourput ("UTXO") model. However, in MimbleWimble there are no addresses, and UTXO values are encrypted by the "blinding factors". Blinding factors are private keys which are only known to the UTXO owner. It is not possible for an observer to deduce any information on ownership or value of a Beam UTXO.

Each user holds keys to their UTXOs

To create a transaction, the sender and the receiver wallets need to first establish communication. Once the communication is established, the sender provides the transaction inputs, and both sender and receiver create their respective outputs with range proofs attesting that the values are non-negative. Both parties sign the transaction and then it is sent out to the nodes.

Transaction Schematics

Source: Beam Management Team

The nodes verify that the sum of inputs and outputs is exactly zero and that the range proofs and signatures are correct. The inputs are then removed from the current UTXO set, and the outputs are saved.

To improve scalability, the MimbleWimble protocol utilizes the Transaction Cut-Through mechanism. For Beam, the intermediate states of the blockchain are not saved. The blockchain only holds the current state of the UTXO set, and thus does not have to grow linearly with the number of transactions.

As an additional privacy mechanism, Beam implements Dandelion. With Dandelion, transactions are not broadcasted to all nodes immediately. Instead, each transaction is passed through several nodes before being broadcasted to the whole network. At each step of the stem phase, the transaction is merged with other transactions arriving at the same nodes, with the addition of special decoy outputs for better obfuscation.

For consensus, Beam uses Beam Hash, a Proof-of-Work algorithm based on Equihash. Beam chose to remain ASIC-resistant in the first 18 months of Mainnet Launch, and has already conducted a hard fork to change the PoW algorithm in order to maintain ASIC-resistance.


Social Community Overview & Strategy

Beam’s community growth strategy is structured around 4 community groups:

  1. Ambassadors
  2. Developers
  3. Miners
  4. Privacy-tech Advocates
  • The Ambassador Program currently has more than 20 volunteers that are responsible for building and managing local communities. The Beam team targets to run around 4 local meetups a month.
  • The Beam team has been active in blockchain events and conferences all over the world, including: Token2049, Slush Japan, Deconomy, Distribute, North America Blockchain Week, Consensus NYC, etc.
  • The team runs an Academic Program in the US to interact with Blockchain Student Associations, currently including that of Harward, Yale, Columbia, UCLA, Stanford, MIT, Carnegie Mellon, etc. The Academic Program will expand to Asia in the near future.
  • The team conducted an online hackathon with Qtum in summer 2019. Another hackathon will be held in September in Germany with Blockmania.
  • Beam states that their strategy with miners will focus on gamification of the mining process.
  • Beam has been creating education material for its communities and several opinion columns in crypto and general-purpose media.
