Both challenges and opportunities, this team hopes to run Ethereum 2.0 testnet with mobile phones

With the arrival of Phase 0 deployment, members of the Ethereum infrastructure team Nimbus are experimenting with a mobile version of the Ethereum 2.0 testnet.

Nimbus network engineer Mamy Ratsimbazafy tweeted on Tuesday:

"The 'ethnimbus' team is currently meeting in Brussels to test the first mobile Eth2 (Ethereum 2.0) testnet."


Nimbus was established by Status Network in 2018.It is currently building an Eth2 client and opened a test network from Nimbus to Nimbus in March 2019. On January 28, it received a $ 650,000 grant from the Ethereum Foundation to continue Eth2's work. After the new grant, Nimbus received a total of $ 1.65 million in funding from the foundation.

Ratsimbazafy said that since the beginning of testing, developers have discovered many bugs in the system and are working to resolve them. To find more vulnerabilities, he said the team needed to implement fuzzing, a testing technique that sends random inputs to the network to trigger extreme situations.

In addition, although the tests so far are mainly based on the Eth2 specification, a fully functional client needs to ensure that other elements-peer discovery and processing, monitoring, performance, automation, etc.-are also robust.

Ratsimbazafy said that Nimbus' Eth2 client is currently running the latest specifications of the Beacon Chain and is ready to integrate with other clients in the near future.

"The team's priority in 2020 is to deliver and participate in multi-client testnets for desktops and mobile nodes, audit and ensure client security, and begin the implementation of Phase 1 and Phase 2 of Eth2."

Mobile-first client

Nimbus is a mobile-first project.

Ratsimbazafy said that the team wanted to ensure that Eth2 was built on mobile, because a large portion of the world's population is accessing the Internet via mobile devices rather than computers.

"If we want to reach these communities, the blockchain must be mobile. This is very important because people in some parts of the world often don't trust centralized services and participants."

Although running the client in a mobile environment lowers the barrier to entry, it also introduces data consumption, battery consumption, and other challenges that are unavoidable in the short term. Ratsimbazafy said developers are currently working to resolve these issues.

"As (Phase 0) deployment approaches, we will increase our automated testing to cover a large number of mobile devices. However, we cannot test the thousands of existing mobile phone models."

Currently, developers can manually install Nimbus on their Android devices using publicly available tutorials. However, Ratsimbazafy said that in the long run, Nimbus will continue to optimize client usability, making it as easy as downloading apps from the app store.
