What's New on Telos

A Word From the TCD’s Head of ZK Technologies — Alberto Garoffolo

In March, we focused on defining our roadmap, which, for instance, includes a SNARKtor POC, HW Acceleration for Proving, and research activities concerning a new model that facilitates Decentralized Parallelizable Provable Computation. Additionally, we prepared presentations for conferences in Hong Kong and Token 2049 in Dubai.
On the development front, we completed the ZKVM proof verifier utilizing Plonky2 primitives and also finalized the gates for the efficient simulation of the arithmetic of the Babybear field. Currently, our efforts are concentrated on the gadgets and, more broadly, on the circuit verifying the ZKVM proof.

A Word From the TCD’s Head of Engineering — Jesse Schulman

March marked the release of version 1.5, a long-anticipated milestone that we are thrilled to have achieved. The team has promptly progressed to work on TelosEVM 2.0, leveraging the features enabled by version 1.5 through updates to Teloscan.
The month was also filled with extensive planning, coordination with new partners, and research and development activities aimed at some very exciting initiatives. These will be unveiled in the coming weeks, starting at Token2049 in Dubai!

TCD Roadmap 2024—

The strategic roadmap for 2024 outlines our key milestones and primary areas of focus. The first quarter of the year has proven to be very successful, and we are dedicated to delivering significant advancements in four critical areas as the year unfolds: the Scalable Proof Protocol, K2-18 (our zkEVM gaming chain), Telos EVM + Telos Zero, and Blockchain-as-a-Service (BAAS).

EVM 1.5 Highlight—

March saw the achievement of a significant milestone on our journey—the release of Telos EVM 1.5. This upgrade reflects Telos' commitment to innovation and sustainability, introducing essential enhancements that strengthen our network's scalability and expand the capabilities of our developer ecosystem. Our efforts are now focused on upcoming updates in EVM 2.0.
