Title: [ANN][tVESP] Vesper testnet-2: privacy coin, ring of 48, operator-less pool, measured leaks, nothing for sale
As private as cash, as global as the internet.
Vesper is a privacy cryptocurrency on its own chain, built to outdo Monero and Zcash: privacy that
is never optional, a ring of 48 for every spend (three times Monero's 16), view keys and
one-payment receipts so you can prove your own history to whom you choose, a Dandelion++-style
relay with its leak measured and published instead of promised, and a mining pool built into the
node with nobody running it (after Monero's P2Pool, with one-time payout keys so the share chain
carries no addresses).
Today it is a public TEST network, testnet-2, open since 1 November 2026. The coins (tVESP) have no
value and never will. There is no sale, no premine, nothing to buy. Every coin is mined, from
block one, by whoever shows up with an ordinary PC; the pool is on by default so a laptop is paid
in small, frequent amounts. The code is plain Python, written to be read.

https://vesperorg.github.io/vesper/join.htmlWhat we want from you: break it. 47 checks run in public on every change; a page lists every
weakness we know, with how likely each is and what is already done about it. The leaks have
numbers: an informed attacker names the real coin in a ring of 48 2.09% of the time (a pure guess
is 2.08%); an attacker running 10% of the nodes names the sender's node 11% of the time against
25% with plain broadcast. Anything beyond that list is a bounty claim: $1,000 pool, paid in
Monero, rules on the Join page. Not audited.
