Starkware Open Sources Key Ethereum Scaling Tech: Starknet Prover

• Starkware announced plans to open source the key technology linked to the Starknet Prover at their Starkware Sessions 2023 event.
• The Prover generates cryptographic proofs for compressed groups of transactions and is the „magic wand“ of the Ethereum scaling project.
• The company has previously open-sourced Papyrus, Cairo 1.0, and established a non-profit foundation with the aim of enhancing development of the software and infrastructure.

Starkware Intends to Open Source Key Technology

At the Starkware Sessions 2023 event in Tel Aviv, Israel, co-founder Eli Ben-Sasson informed attendees that they intend to open source “key tech” linked to their Starknet Prover. This component generates cryptographic proofs for compressed groups of transactions and is seen as a significant step forward in terms of scalability and cryptography.

Previous Open Sourcing Efforts

Starkware has already open sourced their project’s software Papyrus as well as programming language Cairo 1.0. Furthermore, they established a nonprofit foundation aimed at advancing software development and infrastructure related to their technology in November 2022.

Integrations from Major Players

Blockchain API service Alchemy used Ethereum Layer 2 (L2) services such as Starknet in March 2022, while MakerDAO disclosed plans to integrate it in April 2022 with an aim to reduce DAI transfer costs. Payment giant Visa also published a blog post discussing leveraging Ethereum and L2 services like Starknet at the end of December 2022.

Benefits For Developers

Ben-Sasson stated that developers should have full understanding on how this technology works so they can modify it freely while distributing it according to their own discretion – hence why it’s important for them to make it available via open source platforms.


The move by Starkware will allow developers access over this key technology which could potentially revolutionize scaling solutions within cryptocurrency networks such as Ethereum’s network itself. With its recent integrations amongst major players, this move may only increase its potential application further down the line with more widespread adoption expected too if successful after its release under an open source license platform soon.<
