Stay tuned.
More information about the ceremony is coming soon. Meanwhile, learn more about the importance of the trusted setup ceremony 👇
blog.citrea.xyz/whats-a-trus…
Why does Citrea's bridge, Clementine, need this ceremony?
BitVM allows the Clementine bridge to encode the zkSNARK verifier’s checks over Bitcoin Script. Therefore, the bridge requires a one-time setup to generate secure parameters.
What's a trusted setup ceremony?
It's a critical, one-time process for zero-knowledge proof systems like the Groth16 zk-SNARK.
Its purpose is to collaboratively generate a set of public parameters for both the prover to generate proofs and the verifier to check them.
Although Citrea uses the RISC Zero zkVM to produce STARK-based proofs for execution proving, it wraps each STARK receipt into a Groth16 SNARK for fast and easy bridge verification.
Groth16 requires a trusted setup ceremony to ensure the integrity of the proof system.
What's a trusted setup ceremony, and why does Clementine need one?
With Clementine, Citrea expresses a zero-knowledge proof verifier on Bitcoin and builds a trust-minimized peg mechanism around it.
If challenged, Bitcoin (via BitVM) checks a compact proof on-chain 🧵

Tangelo Upgrade is live!
Today at 3:00 PM UTC, Citrea testnet successfully upgraded to Tangelo at block 17733000.
The upgrade strengthens Citrea as we move toward mainnet, which will bring the first wave of ₿apps secured by Bitcoin.

Optimizing Fees for Better User Experience
With the Tangelo upgrade, fee parameters are refined to better match user needs while maintaining full Bitcoin security guarantees.
• Base fees reduced by 90%
• Layer 1 fees reduced by 25%
Implementing Audit Fixes:
We recently completed audits for both Citrea & BitVM-based bridge, Clementine.
The Tangelo upgrade includes all our audit fixes as well as fixes from the BitVM audit itself, bringing major improvements to system reliability, security, and efficiency.
Today, we are introducing Tangelo 🍊, the final Citrea testnet fork before mainnet!
This upgrade includes our final set of testnet improvements as we prepare for mainnet, incorporating all audit fixes and introducing improvements to our fee mechanism.
Welcome Tangelo 🧵

Citrea is building Bitcoin’s first ZK rollup, bringing programmable apps secured by Bitcoin consensus 🍊🍋
Both the rollup and the BitVM-based Clementine bridge have now completed public audits, putting @citrea_xyz in the final stage before mainnet.
here’s why this matters ⬇️
