Grantee Roundup: December 2021 | Ethereum Basis Weblog

It’s all the time enjoyable to listen to about new grants as they’re awarded, however what occurs after the announcement? On this sequence, we’ll verify in on a few tasks which can be nicely underway – or already on the end line. Learn on to study 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” method appears to be like for a sequence that can produce the identical outcomes as the unique whereas consuming much less fuel.

The GASOL crew acquired a grant in February 2021 to construct on their earlier analysis 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 broaden the analysis prototype to a super-optimization toolkit for sensible contract builders, and in the end to make the optimizer integratable with the Solidity compiler.

Model 0.1.3 of the GASOL super-optimization software, 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 embody:

  • Optimization for reminiscence and storage operations in addition to stack operations
  • Testing to match effectivity good points of GASOL vs the Yul optimizer, in addition to GASOL together with the Yul optimizer.
  • Technology 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 capabilities so as 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 desires to dive deep into the technical particulars, the crew has printed reviews on stage 1 and stage 2 of the mission. Observe GASOL on Github to maintain up with future releases!


Layer 2 scaling options have proliferated over the previous 12 months, promising advantages like quicker transactions, drastically decrease prices and elevated privateness. Every L2 strategy makes completely different tradeoffs that have an effect on safety, decentralization, efficiency and useability. For a consumer, this implies freedom to determine what’s most essential to them and select an answer that meets their wants – however staying knowledgeable about an ever-growing checklist of choices may be overwhelming.

L2BEAT helps customers make an informed alternative by providing facet by facet comparisons of options, utilization statistics and potential dangers of lively L2 tasks. The crew behind the web site researches every listed protocol, analyzing numerous knowledge sources and mission documentation to assemble key data 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. Immediately, a customer can toggle between granular monetary knowledge and concisely defined technical danger elements 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 crew, automate processes and broaden their efforts. Deliberate enhancements embody:

  • 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 hold customers knowledgeable about modifications to protocols they’re utilizing

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