Beam: Updated Roadmap Release, DeFi Infrastructure, New MimbleWimble Confidential Lelantus Assets Page, Payment Proofs Explained, AMA Session

Biweekly update 31st January — 14th February

Hello, and welcome to the biweekly update on Beam! The project did over 65 quality releases in its first year of Mainnet, and the level of development performance remains exceptional. The first milestone to mention is a long-awaited in-depth roadmap for the plans ahead, the reasoning behind them, and what all this will mean for Beam. Lots of upcoming dev releases were featured: Double Doppler with Atomic Swap market-making API, instant payments with Laser Beam, Web Wallet and chrome extension; Eager Electron with Confidential Assets Infrastructure, Bridges, Lelantus MW, and one-side payments: Hard Fork with the change of POW mining algorithm to Beam Hash III. In addition, Beam CTO, Alex Romanov, provided an extremely enlightening video about Confidential DeFi Infrastructure and the applications that could be built on it. Another tech milestones were mentioned in a development update, that was also shared by Beam CTO. He reported that a lot of work was done on confidential assets and Lelantus MW infrastructure, web wallet and wallet service, as well as other tasks in progress. In order to educate the community, a tutorial with simple step-by-step instructions on how proof of payment works on private Beam transactions was shared. Double Doppler 4.1 was upgraded with typos, explanatory messages, elements placements, colors — all to make the app more eye-pleasing and more intuitive to use.

Furthermore, Beam had a pretty active public life over the period and was widely covered in media. Beam’s first-ever female ambassador, Kevine Alobadi, was part of a tech event organized by GDG Abomey-Calavi in Cotonou, Benin Republic. It was an excellent opportunity for her to engage and inform the techies in her local region about Beam and the need for confidential assets. Also, an AMA Session was arranged on Reddit with numerous questions from the community to be answered by Alexander Zaidelson and Alex Romanov. By the way, Adshares, a decentralized ad network, added the support of Beam, so currently, it’s possible to pay for advertising services using Beam token.

The community keeps growing in social networks; community members are also stably active in Telegram and on Reddit. Join them — they are always ready to support newcomers! More info to follow. See you in two weeks!

  • Beam Confidential DeFi Infrastructure — Special Edition. Beam CTO Alex Romanov presents an overview of the work in progress Beam Confidential DeFi Infrastructure. Explaining what will be possible on the Beam base layer privacy blockchain and how Beam intends to evolve the product in the future.

The video firstly gives an overview of the infrastructure that they are building, including confidential assets, Lelantus MW, Scriptless Scripts and a new wallet architecture. The second part discusses the applications that are able to be built on this infrastructure. Below are some highlights from the video:

  • Beam did over 65 quality releases in its first year of Mainnet. This is a unique achievement in the space. Beam’s dev team rocks. See post by Guy Corem.

Those are the key features:

  1. CA support

-each UTXO may optionally have a blinded asset tag (similar to the Elements design by A.Poelstra).

-there’s a proof of validity of the asset tag. It’s based on the 1-out-of-many Sigma protocol (by Jens Groth).

2. Shielded pool (a.k.a. Lelantus-MW)

-CA support for shielded operations too

-Support for one-side payments and direct anonymous payments

3. The system design is heterogeneous in nature:

-All kernels carry an excess blinding factor, and (optionally) extra validation rules (height lock, relative lock, etc.)

-Some kernels may control subsystems: Asset control (creation, emission); Shielded operations (mint, spend).

-Those kernels, in addition to contributing to the balance, will have side effects as well.

They will launch a family of products that will serve as a foundation for the Beam Confidential DeFi Ecosystem(again, the first of its kind in the space):

{Before the fork}

  1. Atomic Swap marketplace will leave Beta with numerous UX fixes and API for market-makers. This will improve the liquidity and make it possible for anyone to exchange Beam for BTC, LTC, QTUM (or vise versa) confidentially, without intermediaries and with no counterparty risk
  2. Laser Beam — the Instant payments technology to eventually enable instant immediate payments, micropayments and “streaming” money use-cases.
  3. Exchange rates to fiat and selected cryptocurrencies will be displayed in the Beam wallet, so you can always know how much your Beam is worth if converted to those currencies.

{After the fork}

  1. Web Wallet and Wallet Service API is going to be the focal point of the DeFi ecosystem, bringing Beam to every browser (and to 3rd party wallets integrations) with great user experience and without sacrificing users’ privacy
  2. Confidential Assets on Beam will allow anyone to create and transact new kinds of tokens on the Beam blockchain. These new tokens will have the same confidentiality and great user experience as the native Beam coin. Naturally, support for multiple token types will be added to Beam Wallet.
  3. Bridges to Ethereum will allow creating Beam representation of certain ERC20 tokens and creating 1-to-1 pegs of such ERC20 tokens to their representation on Beam blockchain.
  4. Wallet Auditability — an opt-in feature in the wallet that will allow institutional and business users to seamlessly report their transactions to third parties of their choice.

{Later on}

  1. DeFi Building Blocks. Based on Scriptless scripts technology, they will develop primitives to enable certain kinds of DeFi applications on Beam — think of Collateralized Debt Positions (CDP), lending, STO and more.
  2. Following the development of the Bridges, it will be possible to create Sidechains that will support complementary advanced technologies such as smart contracts with EOS, Ethereum, etc

Privacy enhancements

  1. Lelantus MW will be released on Mainnet. Lelantus MW dramatically increases the UTXO anonymity set and makes it virtually impossible to establish links between different UTXOs.
  2. One-side payments. Based on Leantus MW technology, one-sided payments will allow sending and receiving Beam without Mimblewimble’s interactivity requirement. Today, the receiver must come online at most 12 hours after a transaction is initiated, which may be inconvenient at times. One-sided payments remove that need.
  3. Tor/i2P will enhance layer 0 privacy beyond Dandelion++

Later on:

  1. Dandelion is currently used by the nodes when broadcasting transactions to the network. However, the SBBS messages are currently sent directly by the originator. SBBS over Dandelion will help to obfuscate every message sender.
  2. Mixnet integration to further enhance layer 0 privacy

Security enhancements

  1. Ledger and Trezor support. Bringing Beam to Ledger and Trezor hardware wallets turned out to be a complex task. They have recently done a lot of progress in reducing the memory footprint and computational complexity of Beam integration, which will allow support of the most popular Ledger and Trezor models.
  2. Multisig support will allow committing transactions only when approved by multiple signatures. Standard “M out of N” schemes will be implemented.


  1. They want to remove the current limitation of not using the same seed phrase from several wallets simultaneously, so at first, we’ll enable sync of balance and transactions history; later on, full sync (addresses, full transaction data) will be implemented
  2. Notifications about the new version for desktop wallets will come handy so you’ll always be up-to-date

Miscellaneous (others)

  1. Beamhash III will be the final Beam POW algorithm. BeamHash III is proof of work designed to create a smooth transition from GPU mining to Asics in the future. While perfectly fitted to today’s capacities of GPUs, especially their memory bandwidth, it also will allow rather simple and cost-efficient asic designs. Compared with the current BeamHash II algorithm the performance of BeamHash III is more independent of the underlying GPU architecture and less energy-consuming. Furthermore, upcoming Asics may be produced using a more power and cost-efficient chip design as well.
  2. GhostDAG consensus upgrade, when activated, will enable much better mining decentralization, faster confirmation on L1 (seconds) and much higher throughput (Transactions/sec), which will serve to keep fees low even when demand for Beam and Beam’s CAs will soar.
