Bitaigen Research In this article we systematically review privacy‑coins built on the MimbleWimble protocol such as Beam, providing a panoramic analysis that covers technical foundations, consensus mechanisms, and ecosystem layout. Official entry points and information on major exchanges are also listed to help readers quickly grasp core characteristics and development trajectories. Subsequent sections will dive deeper into the supply model and incentive structures, making a thorough read worthwhile.
What Is the BEAM Coin?
Beam is a privacy‑focused cryptocurrency built on the MimbleWimble protocol. All transactions are anonymous by default, and the network offers fast synchronization and strong scalability. The total supply is capped at 262.8 million BEAM, and the chain uses a Proof‑of‑Work (PoW) consensus with the Equihash mining algorithm.

Technical Snapshot
- Project launch: Development started in April 2018; the mainnet went live on 3 January 2019 at 22:00 (Beijing Time).
- Implementation language: MimbleWimble was written from scratch in C++.
- Consensus mechanism: PoW combined with Equihash.
- Issuance model: No pre‑mining, no ICO.
- Block production: Approximately one block every 60 seconds, each block can hold about 1,000 transactions and is roughly 1 MB in size.
Total supply: 262,800,000 BEAM
Block reward schedule
| Reward period | Block reward (BEAM) |
|---|---|
| Year 1 | 80 |
| Years 2‑5 | 40 |
| Years 6‑9 | 25 |
| Every 4 years thereafter the reward halves, continuing until year 133 when mining ends |
- ASIC resistance: For the first 12‑18 months after launch the network maintains ASIC resistance to promote decentralization. Subsequent hard forks will adjust the algorithm, with details announced before each fork.
- Team maintenance: The Beam Foundation operates the project; core developers and the foundation share a portion of the block reward to fund ongoing maintenance and development.
Key Features of Beam
- Privacy: All transactions are confidential; no participant information is stored on‑chain.
- Generality: Using “scriptless scripts,” Beam supports value transfers, atomic swaps, escrow, timed transactions, and other use cases.
- Optional auditability: Users can attach an immutable digital signature file (e.g., invoice or contract) to a transaction and grant a designated auditor permission to view it.
- Asset confidentiality: The private transaction mechanism enables the creation and circulation of tokenized real‑estate, corporate bonds, and similar assets without exposing ownership details.
- Scalability: MimbleWimble’s “cut‑through” design drastically reduces on‑chain data, keeping the Beam blockchain size far smaller than that of most public chains.
- Sustainability: The project is open‑source and community‑governed; Beam Growth Pool allocates 20 % of mining rewards to a development fund that supports ecosystem growth and promotion.
- Usability: Mobile and desktop wallet apps include dashboards for budgeting, income, and expense tracking.
- Compatibility: By adopting the industry‑standard Equihash algorithm, Beam’s tooling suite supports GPU miners for straightforward deployment and management.
How Beam Operates
- Transaction creation: A wallet holder initiates a transaction over a secure channel; both parties sign using the Schnorr protocol.
- Submission to nodes: The transaction contains inputs, outputs, fees, and kernels expressed as Pedersen Commitments, together with a non‑interactive zero‑knowledge range proof.
- Node validation: Nodes verify the transaction against the latest Merkle tree state; the root hash and the PoW are written to the block header. Syncing nodes periodically generate compressed history to enable “fast sync.”
- Mining pool entry: The transaction enters the mempool; roughly one block is mined each minute.
- Block broadcast: The new block propagates across peers; the longest valid chain becomes the new tip, and consensus is reached network‑wide.
- Fast sync: New nodes can request only the compressed system state and block headers, avoiding the need to download the full transaction history.
