What is in it for you?

How do you run code on the blockchain? It all starts with a virtual machine.

If the prospect of solving challenging low-level problems on a collaboration-focused team to build the foundation of the future blockchain interests you, let's connect…


How you will contribute…

We need people who are interested in our day-to-day challenges and the willingness to take ownership of complex problems as we design from-scratch our virtual machine:
• Bytecode instrumentation
• Concurrent task scheduling and data hazard management
• Data store design and optimization
• Determinism analysis
• Task isolation design (security)
• Reentrant data consistency
• Profiling analysis and optimization

Beyond the day-to-day, we also need to discuss the future and how to build it:
• How do we scale the blockchain?
• What is an ideal bytecode language?
• What is an ideal application language?

If any of this sounds interesting to you, we would like to talk to you.
