Grantee Roundup: December 2021

It’s at all times enjoyable to listen to about new grants as they’re awarded, however what occurs after the announcement? On this sequence, we’ll examine in on a few tasks which might be nicely underway – or already on the end line. Learn on to find out about some latest milestones and achievements by grantees!

GASOL (GAS Optimization TooLkit)

The COSTA group works on formal methods, modeling and implementations associated to verification and optimization of applications. Members Elvira Albert, Pablo Gordillo and Albert Rubio are making use of that experience to Ethereum sensible contracts with GASOL, a framework for optimizing fuel consumption. Each Ethereum sensible contract executes a sequence of EVM directions known as opcodes; GASOL’s “super-optimization” approach appears to be like for a sequence that may produce the identical outcomes as the unique whereas consuming much less fuel.

The GASOL workforce acquired a grant in February 2021 to construct on their previous research and experimentation with Ethereum sensible contract optimization. They already had a prototype for computing optimized EVM sequences for a subset of opcodes, particularly stack operations. The objective of the grant is to develop the analysis prototype to a super-optimization toolkit for sensible contract builders, and finally to make the optimizer integratable with the Solidity compiler.

Model 0.1.3 of the GASOL super-optimization instrument, and directions for utilizing it, can be found on Github. In its present model, GASOL is ready to each compute optimized sequences and produce corresponding executable bytecode. Different options and achievements embrace:

  • Optimization for reminiscence and storage operations in addition to stack operations
  • Testing to match effectivity positive factors of GASOL vs the Yul optimizer, in addition to GASOL together with the Yul optimizer.
  • Era of a log file to confirm that bytecode uploaded to Etherscan has been generated by GASOL
  • Prolonged the SMT mannequin to outline the order of reminiscence accesses and features to be able to retain the identical reminiscence state as the unique
  • Some elements of the optimizer have been generalized to allow byte-size optimization standards

For anybody who needs to dive deep into the technical particulars, the workforce has revealed experiences on stage 1 and stage 2 of the undertaking. Comply with GASOL on Github to maintain up with future releases!


Layer 2 scaling solutions have proliferated over the previous yr, promising advantages like quicker transactions, drastically decrease prices and elevated privateness. Every L2 strategy makes totally different tradeoffs that have an effect on safety, decentralization, efficiency and useability. For a consumer, this implies freedom to determine what’s most vital to them and select an answer that meets their wants – however staying knowledgeable about an ever-growing record of choices could be overwhelming.

L2BEAT helps customers make an informed alternative by providing aspect by aspect comparisons of options, utilization statistics and potential dangers of energetic L2 tasks. The workforce behind the web site researches every listed protocol, analyzing varied knowledge sources and undertaking documentation to collect key info into one clear, accessible supply.

When L2BEAT first acquired funding in spring 2021, the dashboard listed scaling expertise and locked worth statistics for every of 10 protocols. The location, together with the L2 ecosystem, has grown significantly since then. At present, a customer can toggle between granular monetary knowledge and concisely defined technical threat components for 20 protocols, together with a web page devoted to anaylsis of every protocol’s options and tradeoffs.

In December, L2BEAT was awarded a second grant to assist develop their workforce, automate processes and develop their efforts. Deliberate enhancements embrace:

  • Constructing out a again finish server and database sturdy sufficient to deal with the complexity of present and deliberate options
  • Including extra stay metrics together with transaction quantity, uptime and block manufacturing
  • Including improve logs to assist maintain customers knowledgeable about adjustments to protocols they’re utilizing

Try for a treasure trove of details about L2s with far more to come back, observe @L2beatcom on Twitter, or be a part of the neighborhood Discord. The workforce additionally welcomes contributions!
