• Around 80% of your time will be spent on new feature development, not maintenance.
• You will work in the domain where compilation time consuming, computationally heavy optimizations are possible and profitable.
• You will work in the domain where good toolchains aren’t common, so your work could make other developer’s lives noticeably better.
• You will have an opportunity to own a big part of the codebase, be independent in task prioritization, and be measured by results only..
• You will work remotely with a flexible schedule.
• You will be heard by leadership and other members of the team.
• You will be compensated in the top 15% of the market and will be entitled to generous share options
  
  
  

• zkSync EraVM back-end migration to the latest version of the ISA
• Back-end optimizations - better selection patterns, better ISA utilization, peephole passes, etc.
• Optimizer tuning - zkSync EraVM is different from a typical LLVM target, so passes like instruction combiner need to be configured, and the pipeline itself has to be tuned
• Front-end optimizations - our front-ends currently produce correct IR, but it lacks attributes and metadata that would make analyses and transformations more efficient
• Debug information and debugger support
• Profiler support
• Binary format development and linker integration - we currently use a custom linker written in Rust and want to migrate to LLVM one day
  
  
  

• We expect you’ve spent around 5 or more years working on projects that use LLVM or on LLVM itself and learned LLVM in breadth or depth.
• You ideally have experience implementing MLIR or LLVM IR-level optimizations.
• We expect you are capable of writing maintainable code in modern C++.
• To understand the connection between programming language design and compiler implementation, we expect it to be true with respect to the very language you program in.
• You can deliver results with no supervision.
• We like critical thinkers and people that communicate when they see something wrong

Context

The PriCLeSS project establishes a cross-disciplinary partnership to understand the legal challenges and address the technicalobstacles associated with data storage in a blockchain context.

From a technical perspective, the project focuses on designing algorithmic responses to the legal issues that arise when using blockchain technology to handle personal data.

In this context we first proposed Splitchain, a novel fully decentralized state-sharding solution that does not require the maintenance of a synchronization blockchain or any heavy synchronization mechanisms, allowing shards to progress at their own pace in a non-blocking manner. Then, we augmented SplitChain with the ability to enforce geographical or administrative constraints in the placement of data thereby addressing some of the requirements of privacy legislation like the GDPR. We refer to this augmented version as SplitChain2.

Assignment

This engineering position involves implementing first SplitChain and then SplitChain2. In this task the engineer will be guided by the team who have been working on SplitChain and SplitChain2 consisting of Antoine Rault, Davide Frey and Emmanuelle Anceaume from Inria, and Damien Franchi and Sandrine Turgis from the IODE Team at the University of Rennes. The engineer will also have the opportunity to collaborate with other partners from the PriCLeSS project.

Main activities

The engineer will follow the following approximate timeline.

-M1-M2: Analysis of the state of the art:

• Sharding and Proof-of-Eligibility consensus implementations.
• Research paper on SplitChain
• Current working Draft on SplitChain2

-M3: High-level design of the implementation.

-M5: Single shard implementation, with features for multiple shards and privacy (indirection, encryption, etc.).

-M8: Hypercube routing for inter-shard communication.

-M12: Prototype implementation of the complete system.

Technical skills:

• Proficiency in Rust or willingness to learn the language and use it
• At least basic terminal usage: bash or other environments
• Familiarity with git
