Grab a seat and join us live in 30 minutes, right here on X or YouTube, for a new episode where our hosts, @joaopdgarcia and @GCdePaula_, unpack what raising the bar for Ethereum scaling really means with @bkiepuszewski and @donnoh_eth from @l2beat. →

🟢 SΞR NEWS: @cartesiproject has acquired 251 ETH ($930K), increasing their ETH reserve to 1,037 ETH. New rank: #38 (from #42). Welcome to the 4-digits club.

The Cartesi Foundation has now completed the $500,000 USD open market purchase of $CTSI, reaffirming its support for the ecosystem, developers, and broader community. This highlights a strong belief in the project’s vision and capacity to shape the future of dApp development.

This Wednesday on IBTIA, we hand the mic to @bkiepuszewski and @donnoh_eth from @l2beat to unpack their perspective on rollup standards, risks, recategorization, and what it means to truly raise the bar for Ethereum scaling. Tune in! → or live here on X

Here is the group's most recent publication, in which we used @cartesiproject Rollups to implement a decentralized and verifiable model for verifying GPS data.

Cartesi is now part of the Strategic ETH Reserve, supporting the long-term resilience of Ethereum. By joining SΞR, the Cartesi Foundation reinforces its radical focus and deep commitment to contributing to Ethereum’s future. This marks another step in our mission within the Ethereum ecosystem, as detailed in the latest blog post:
