CPU‑only or not: CPU‑only (mining on ordinary desktops)
Brief description: A post‑quantum cryptocurrency using the Bitcoin architecture (UTXO, Script, P2P) but with completely replaced cryptography to protect against quantum computers. The code contains no libsecp256k1 library at all.
Where to mine/pool: Not specified (developer announced a CPU miner release soon)
Community reaction: Suggestion from the Chainquiry directory to add the project to the database; developer confirmed that the genesis block has already been mined and the code is open‑source.

Main theme of new posts: Announcement of Tessera (TSR) being added to the Chainquiry directory.
Main characteristics highlighted: post‑quantum ML‑DSA‑44 signatures, no elliptic‑curve cryptography, SHA3‑256d PoW with CPU mining from the genesis block, architecture derived from Bitcoin Core (UTXO, Script, full node).
Official sites and repository listed (gettessera.org, GitHub, Discord).
Issues/complaints: None reported.
Overall tone: Positive/neutral – simply informs about the listing and confirms the project's openness.

Main theme of new posts: Forum participant adamant.im left a constructive review and asked a series of technical questions about the implementation of the post‑quantum cryptocurrency Tessera (TSR), focusing on signature size, wallet usability, and the resistance of the PoW algorithm to ASIC/FPGA.
Key news/updates: No official updates from the developers in this set of posts; earlier posts already reported the mined genesis block and open‑source code.
Issues/complaints:
ML‑DSA‑44 signatures are significantly larger than secp256k1, which may increase transaction size and block weight, potentially putting pressure on fees and requiring changes to relay policies.
It is unclear how familiar Bitcoin‑tool addresses and script templates will remain for users; a dedicated Tessera wallet may be needed.
Despite the claim of a CPU‑only PoW (SHA3‑256d), there are concerns that ASIC/FPGA hardware for this algorithm could appear sooner than expected, and no published estimates of the resistance window to such equipment exist.
Overall tone: Constructive and neutral‑positive – interest in the project is present, but it is accompanied by practical questions and caution regarding possible limitations.
