Brave Browser, the privacy-preserving web browser project powered by the Basic Attention Token (BAT), has announced the launch of Mjolnir, a tool the team says facilitates the deployment and benchmarking of implementations on the Ethereum blockchain, according to a blog post on May 11, 2020.

Brave (BAT) Unveils Mjolnir

As part of larger plans to establish an entirely decentralized privacy-centric ecosystem for digital advertising, the Brave team has launched Mjolnir, a tool that it says will enable it to test various blockchain frameworks easily, as it plans to incrementally decentralize the components of its platform, while also improving the security and privacy offered by the BAT ecosystem.

As stated in its blog post, while public blockchains such as Ethereum allows anyone to add or verify data on the network, making it very decentralized and censorship-resistant, these networks, however, have very abysmal transaction throughput, high execution costs and lack privacy, as compared to permissioned blockchains.

Against that backdrop, the Brave team says it sees permissioned blockchains as a more reasonable compromise and the most suitable technology for the Apollo phase of the BAT ecosystem.

Brave says:

While Ethereum Clients are a core component of Web 3.0, the lack of standardization across these clients makes it difficult to test the technology. To remedy this and enable testing on a level playing field, we developed Mjolnir, a tool for deploying and benchmarking Permissioned Ethereum Blockchain implementations easily. We hope that other teams can benefit from the results and use the tool for their testing.

Evaluating Mjolnir 

Brave says it used two permissioned distributed ledgers: Quorum running Istanbul Byzantine Fault Tolerance (IBFT) and PoA and lab10Coop’s fork of the Parity Ethereum Client powered by the Honey Badger Byzantine Fault Tolerance (HBBFT) algorithm,  to test the effectiveness of Mjolnir.

Brave says the Quorum permissioned blockchain outperformed HBBFT in terms of transaction throughput, with a massive 890 TPS, as compared to the latter’s 790 TPS. However, HBBFT consumes less memory per node and it’s more resistant to clock skew.

In an effort to encourage more developers to carry out further extensive experiments with Mjolnir and see how it performs in real-life situations, the Brave team says the tool is now publicly available and open-source.

Since its launch in May 2015, Brave has continued to move in an upward trajectory and the innovative platform now boasts over 13.4 million monthly active users.

In April 2020 Brave integrated the Binance widget into its desktop browser to make it easier for users to buy Bitcoin (BTC) and other cryptos.

On May 8, 2020, BTCManager informed that Brave has rolled out several initiatives aimed at enabling non-profits to better tackle the ravaging COVID-19 pandemic.
