Quantstamp Protocol Progress

The Quantstamp Protocol is why Quantstamp was started, so improving it is a fundamental mission for us. This month we made progress on the next version of the Quantstamp Protocol: we enhanced the UI, and are opening access to our documentation and code. In addition, we did extensive internal alpha-testing of Quantstamp Assurance, our post-deployment security project.

Betanet UI

We’re testing and developing a much-improved user interface for the Quantstamp Betanet Protocol. This new interface will have a streamlined user flow, and also provide more live statistics on node status and events.

Open sourcing the protocol

Besides working to improve the protocol, we are also working to open access to it. Currently, we are refactoring our code and documenting it in preparation for this step. Open sourcing our protocol code is a whitepaper goal and provides transparency for users of the Quantstamp Protocol.

Quantstamp Assurance Protocol Alpha Testing

Quantstamp Assurance is a new project we are developing that aims to provide assurance of smart contract security even post-deployment. In February, we created an alpha version and performed extensive internal testing on a variety of smart contracts. This alpha test provided us a lot of valuable feedback which we’re using to improve and iterate our Quantstamp Assurance design. Audit

In February, we completed our audit of the Chain. is the team behind the MCO Visa Card, a prepaid Visa card that allows users to spend cryptocurrencies easily and receive rewards. They recently announced the Chain, a public blockchain focused on facilitating mobile crypto payments. As described by, it allows for fast settlement and provides rewards for merchants and consumers who use it for transactions.

We were happy to audit the Chain smart contracts and help them in their mission of faster, easier online payments with lower fees. Auditing the Chain continues Quantstamp’s track record of helping secure projects aiming to improve mainstream adoption of cryptocurrencies and blockchain technology.


We had a great time this month at ETHDenver, where our CEO Richard Ma led team “Beacon Thugs and Harmony” at a 36 hour hackathon to work on the Beacon Chain — an essential component of the next version of Ethereum. Watch “Beacon Thugs and Harmony” pitch their ETH2.0 beacon chain simulation at the semifinals.

Besides the Beacon Chain, Quantstamp also audited the BuffiDAI token — the official cryptocurrency of ETHDenver.

BuffiDai Audit

The team was excited to audit ETHDenver’s local cryptocurrency, BuffiDAI. BuffiDAI is tied to the value of the DAI, a stablecoin created by MakerDAO. It was used successfully at ETHDenver to create a frictionless payment experience for attendees to purchase local products and services.

See it in action in this video, where our Community Manager Jared Harrill buys a sushi bowl at a food truck using BuffiDAI. Compared to using cash or credit cards, the transaction is much smoother. The chef never needs to stop what he’s doing to manage the payment, and he receives instant notification when the transaction goes through.

Beacon Chain Hackathon

Working for 36 hours straight, with very little sleep, our CEO Richard Ma led team “Beacon Thugs and Harmony” to create a simulation of the Beacon Chain, an essential component of the next version of Ethereum. The Beacon Chain is the coordination layer for Ethereum 2.0.

You can view our simulation at and see our team explaining what we built in this Youtube video. We’re proud to have been a part of building the next version of Ethereum.

Mobility Open Blockchain Initiative

We hosted MOBI, a blockchain initiative for autonomous driving and mobility, at our San Francisco headquarters. The initiative gathered many big players in the automotive and blockchain industries, such as BMW and R3. We discussed how to use blockchain and related technology to make mobility safer, greener, and more accessible.

Hyperledger Meetup at Quantstamp HQ

On February 25th, we hosted a meetup where Quantstamp CTO Steven Stewart discussed lessons that Quantstamp engineers learned while developing and auditing decentralized applications. Steven also discussed the results from our internal alpha-test of the Assurance Protocol, a new decentralized app we are researching. Watch the video on Youtube.

Following Steven’s presentation, Arnaud Le Hors, a Senior Technical Staff Member of Web & Blockchain Open Technologies at IBM, gave the audience an update on Hyperledger Fabric.
