Stealth (XST) began as StealthCoin in July of 2014. It was the first proof-of-stake (PoS) currency with integrated Tor routing. Its other leading innovation at the time was StealthText, a proof of concept SMS routing layer for cryptographically secure, private cryptocurrency transactions. Stealth was distributed through fair proof-of-work (PoW) mining, that met all standards for fairness at the time of launch. Stealth had a tiny pre-mine of 1% of the final PoW money supply, of which most remains. The premine funds have been distributed as bounties through a transparent process ( https://tinyurl.com/stealthpremine ). Stealth development is currently pioneering a new consensus protocol called Quantum Proof of Stake (qPoS, https://tinyurl.com/stealthqpos ), which will enable nearly instant, cryptographically private transfers on the blockchain.
