Preguntas frecuentes


¿Por qué el mundo necesita otra moneda?

Bitcoin was a great blessing, showing people a way to a truly decentralized and deflationary currency and blazing the path towards a future where our money and finances are neither controlled nor scrutinized by anyone. Hundreds of new coins appeared, some of them minor variations of Bitcoin, some offering new possibilities.
However, the fact that transactions on Bitcoin and many of its derivatives are not confidential (all transaction history is stored in a public ledger accessible to anyone), makes cryptocurrency use in real life quite problematic. Can anyone think of a business that would want all its income and expenses to be seen by its competitors?
Privacy coins (like Monero, Zcash and their derivatives) have great merits and technology while providing good confidentiality, but do not fully deliver on scalability and decentralization. Another important quality is auditability - with Monero or Zcash it is impossible to demonstrate a provable transaction graph to an external auditor, which is often needed for businesses.
The ideas behind Mimblewimble protocol allow for creation of a coin that is confidential, scalable and optionally auditable.
We believe that the Beam coin will serve as a truly usable confidential store of value, with an addition of second-layer solutions like Lightning to allow for day-to-day usage.

Si eres tan pro Mimblewimble, ¿por qué no te uniste a Grin?
Yes, we believe in Mimblewimble!

We believe that rapid innovation is best achieved in a startup model, where people are 100% focused on the project and are working on it literally 24/7. Also, we feel that some of the technical decisions made by the Grin team are less practical and use more “cutting-edge” technology. Since we are literally building money, we chose a more conservative approach and decided to use more proven technologies instead - that’s why we chose C++ and not Rust, Equihash and not Cuckoo Cycle, etc. That said, we have immense respect for the Grin team and wish them success. We are all working towards the same goal - bringing financial privacy back to people and making cryptocurrency more usable in real-world applications.

¿Cuál es la diferencia entre Beam, Zcash y Monero?

El mundo cripto ofrece varias monedas de privacidad, pero ¿cuáles son las principales diferencias entre ellas en comparación con Beam? [Aquí vamos.] (http://www.medium.com/beam-mw/whats-the-difference-between-monero-zcash-and-beam-953eafd89354)

¿Cual es la diferencia entre Beam y Grin?
Both Beam and Grin are implementing the Mimblewimble protocol, but in different ways. We summarize the differences in four different areas: Technology, Emission, Features, and Governance.

Technology Here’s a brief comparison of the technologies used by both projects:

  • Programming Language
    • Beam: C++
    • Grin: Rust
  • Mining Algorithm:
    • Beam: Modified Equihash
    • Grin: Cuckatoo32+, plus Cuckaroo29


Beam uses a capped emission model of about 263 million total coins (see “What’s Beam Emission Schedule”). Grin uses a constant emission of 1 grin per second (60 per 1-minute block).


While both projects are adding functionality all the time, the known feature list planned for launch is as follows:

  • Desktop Wallet
    • Beam: GUI and CLI (Command-line interface) for Windows, OSX and Linux
    • Grin: CLI for Linux, OSX and Windows Web wallet interface
  • Mobile Wallet
  • Interactive Transactions (both wallets online)
    • Beam: Yes
    • Grin: Yes
  • Non-interactive transactions (wallets don’t have to be online at the same time)
    • Beam: Yes, transparently from the Wallet, using Secure BBS
    • Grin: Yes, using email or similar
  • Transaction Graph Obfuscation
  • Atomic Swaps
    • Beam: Bitcoin <> BEAM, Litecoin <> BEAM, Qtum <> BEAM
    • Grin: Ethereum <> Grin
  • Auditability
  • Confidential Assets
    • Beam: Available - possibility to issue additional tokens on Beam blockchain
    • Grin: Not yet


Beam runs as a classical startup. We raised money from investors and pay salaries. In the future, Beam plans to pass governance of the protocol to a Beam Foundation (see “What is Beam Foundation”). Grin is a 100% volunteer project fueled by community enthusiasm and occasional donations, supporting one paid developer. For the first two years, Grin will be governed by the core development team with input from the community.

El * groth * es la unidad más pequeña de Beam grabada en la blockchain. Es la centésima millonésima parte de un solo Beam (0.00000001 BEAM).

La unidad ha sido nombrada en homenaje a Jen Groth, Prof. de Criptología en la UCL. Obtenga más información sobre cómo el Prof. Groth se convirtió en una unidad monetaria fraccionaria here.


¿Cuál es el calendario de emisiones de Beam?
Beam tiene un suministro total limitado, con un total de 262,800,000 monedas. Nuestro calendario de emisiones es el siguiente:
  • La recompensa del primer año es de 80 monedas por bloque.
  • Años 2,3,4 y 5 - 40 monedas por bloque.
  • En los años 6-9 la recompensa de bloque es de 25 monedas.
  • Después, se reduce a la mitad cada cuatro años hasta el año 133, cuando se detiene la emisión.

En los primeros cinco años de existencia de Beam, se emitirán monedas adicionales a [Treasury] (/faq /what-is-your-finance-model-what-is-the-treasury):

  • Primer año: 20 monedas por bloque.
  • Años 2,3,4 y 5 - 10 monedas por bloque.

Se puede ver que nuestro programa de emisiones se basa en el modelo de Bitcoin, la principal diferencia es una mayor recompensa de bloque durante el primer año. El razonamiento para la recompensa del bloque más alto en el primer año es asegurarse de que los mineros tengan un gran interés en la minería Beam a principios de su existencia y ayudar a introducir la moneda Beam en el mercado.

Se puede encontrar una información más detallada sobre el programa de emisiones de Beam [here] (https://medium.com/beam-mw/mimblewimble-emission-schedule-215551948259)

¿Por qué Beam es deflacionaria?
El suministro controlado, junto con la falta de una parte controladora confiable, es uno de los principales beneficios cuando se trata de criptomonedas; y el éxito de Bitcoin es un testimonio de la solidez de ese enfoque. Esta es la razón por la cual Beam eligió ser deflationary.
¿Qué es la Auditabilidad?
Auditability feature is an extension that we added to original Mimblewimble protocol, allowing businesses or private individuals to report their financial history to their auditors or any other party of their choosing in a secure and provable way. If the user chooses to use Auditability (btw, we may change this unwieldy name in the future), her wallet generates several key pairs for audit. Alternatively, a public key can be provided by an auditor (think of EY, Deloitte, KPMG or PWC) and added to the wallet by the user. Transaction details are encrypted with that key and attached to the original transaction (that remains private), along with a proof that those details match. The user can also include additional information (e.g. digital documents, signatures, etc.) in the metadata of each transaction by storing the hash of such documents in the blockchain. With Auditability, each transaction is tagged, such that only an Auditor may identify it in the blockchain using the public key. The auditor is not, however, able to create such a transaction, nor spend any money. The auditor can retrieve all the tagged transactions form the blockchain, make sure that the transactions comply with the presented documents. Auditability is strictly an opt-in feature. If the user hasn’t chosen to be auditable, there is no way anyone can retrieve any information about his transactions from the blockchain.


¿Cómo puedo comprar Beam?
Beam se puede comprar en más de 20 exchanges y, debido a su identidad, se puede extraer en un modo individual o mediante un grupo de minería. La lista completa de exchanges que ofrece Beam se puede encontrar en nuestra Homepage.
¿Cómo puedo apoyar a Beam?
Beam has a fast-growing Ambassador program based on locality. Our ambassadors promote Beam by organizing meetups, holding talks and conducting knowledge-sharing sessions. So if you are highly motivated, really good at conveying ideas and communicating with people, and excited by our implementation of Mimblewimble (or just crypto in general), we might need your help. Beyond the obvious reward of being first Beamer in your crypto community, we are happy to let you know there is compensation involved. Drop us an email to [email protected] with a brief bio and why you think you'd be a great fit to represent Beam in your area.
¿Hace Beam Airdrops?
No. Beam no lo hace y no hará airdrops. Cualquiera que intente ofrecerle la participación en un lanzamiento de Beam es un estafador. Nunca le pediremos que nos envíe fondos en Beam o cualquier otro cripto, y no le pediremos su dirección de wallet.

Instamos a nuestra comunidad a tener mucho cuidado y no caer en intentos de estafa.

¿Cuando tendremos el Lambo?
No nos gustan las cosas ruidosas, brillantes y poco prácticas. Así que no hay Lambos para nosotros.


¿Cuántas transacciones por segundo soporta Beam?
Thanks to the Mimblewimble protocol, Beam supports around 17 transactions per second. While this number is higher than Bitcoin and other existing privacy coins, it is important to emphasize that it is not high enough to use Beam as a means of exchange. In the future, it will be possible to improve transaction throughput by using a second layer out-of-chain solution such as Lightning, Thunderella or similar. Then you should be able to pay for your lattes with beams. Until then, Beam’s primary use case is store of value rather than day-to-day payments.
¿Cuál es el tiempo de bloque y el tamaño del bloque?
En Beam, se creará un bloque aproximadamente cada minuto. Cada bloque contendrá alrededor de 1.000 transacciones.
¿Cuál será el tamaño de tu blockchain?
Instead of storing the full transaction history as in Bitcoin and other coins, a Beam node only needs to store the current UTXO state, instead of the entire transaction history. Validity of the history that brought us to this state can be confirmed by storing only the headers of the previous blocks; which holds the proof of validity of previous states (using a structure called a Merkle tree) and Proof of Work that allows to reach consensus on which of the header chains should be considered the correct one in case of blockchain branching. This is achieved using cut-through, one of the core concepts in Mimblewimble. We are still experimenting and evaluating, but it is a reasonable estimate that the Beam blockchain will be less than 1/3 of Bitcoin’s blockchain size, possibly as low as 10% (assuming the same amount of activity). So, really small.


¿En qué plataformas funcionará el wallet de Beam?
El Wallet de Beam está disponible para los siguientes sistemas operativos: Windows, Mac y Linux.

Hemos lanzado tanto Android como iOS Wallets, puede descargarlos a continuación:

¿Qué pasa con las wallets de hardware?
Super importante La wallet de hardware es lo más seguro para su riqueza digital, y una buena cantidad de monedas de valor debe ofrecer la integración en wallet hardware. Entendemos eso y estamos trabajando con varias compañías de wallets de hardware para desarrollar dicha integración.


¿Por qué Beam utiliza la minería Equihash?
We chose Equihash because it has been around for a long time and Equihash PoW mining algorithm is well adopted by miners globally. Equihash is based on solving the Generalized Birthday Problem. It is I/O bound, meaning that it requires quite a large amount of memory as opposed to Bitcoin's SHA256 that requires a lot of processing power. Equihash is built in such a way that does not allow an easy tradeoff between processing power and memory thus making it difficult to use with ASIC miners that existed at the time of its creation. Today there are dedicated ASIC miners that can mine Equihash ten times more efficiently than average CPU.

Beam used PoW algorithm Beam Hash I until its first Hard Fork that occurred on August 15th, 2019. Since then, Beam uses Beam Hash II. More details on Beam Hash II can be found here.

For more details, read this in-depth article about our Equihash implementation.

Last update: August 19th, 2019

Resistente a los Asic
Para garantizar una mejor descentralización, Beam planea mantener la resistencia de ASIC en los primeros 12 a 18 meses. Para lograr esto, planeamos realizar uno o dos hard fork, primero después de aproximadamente 6 meses de existencia y otro después de aproximadamente 12 meses. Cada hard fork cambiará el algoritmo de minería. Las modificaciones exactas se revelarán varias semanas antes de la horquilla dura real


¿Qué es el modelo de gobierno de Beam?
The Core Team and Beam Development Ltd. do not have any intentions to govern Beam in the long run. There is no point to having a cryptocurrency governed in a centralized way by a corporation. Therefore, we offer our solution to our community. We are opening the code, welcoming Open Source Developers and setting up a non-profit foundation that will be unconditionally funded by the Treasury.
¿Qué es la Fundación Beam?
Beam Foundation will be responsible for supporting, promoting and further developing Beam in the years to come. The foundation will be set up as a non-profit and will be governed by a Board of Directors comprising reputable industry figures. The foundation will be receiving a significant part of the Treasury, and will fund projects and initiatives in the areas of Applied and Basic research, Development of Beam and Mimblewimble, Awareness, Financial Literacy and more.
¿Quién es el equipo de Beam?

Beam has put together a remarkable team of first-class engineers and entrepreneurs, and a strong advisory board comprised of accomplished cryptocurrency veterans. We have 8 full-time developers, a marketing team and seasoned management. Beam CEO is Alexander Zaidelson, an experienced entrepreneur, executive and VC investor, the engineering team is led by CTO Alex Romanov (over 15 years experience running complex R&D projects in numerous industries), the operations are run by COO Amir Aaronson, experienced entrepreneur and executive, and marketing is under the lead of CMO Beni Issembert, an entrepreneur with more than 15 years of experience in the Corporate and Performance marketing.
Our Product Management is done by Sasha Abramovich, a top-notch Product Owner with solid technical background, ex-Agora, AppsFlyer, Natural Intelligence and more. The list of advisors includes people like Guy Corem, Bryan Bishop, Gordon Chen, Rami Kasterstein, Ferdous Bhai, Liraz Siri and Addison Huegel. Check out our Team Page for details. We are actively building a global community of developers who share our mission of creating a private digital currency and will maintain and improve Beam.

¿Cuál es su modelo de financiación? ¿Qué es la tesorería?
We believe a startup environment is best for innovation, that's why we are raising money. Treasury model is the best way to repay our investors and to provide a reward to the founding team. Treasury works in the following way: in the first five years of Beam existence, 20% of all emitted coins automatically go to the Treasury. Technically, the additional coins are emitted for each mined block. Our investors, the core team, our advisors and the non-profit Beam Foundation will be getting Beam coins from the Treasury on a monthly basis. We believe that the five year payout period creates an alignment of interest between all the parties and ensures that our coin will get the support it requires to succeed.
