The "Company Values" section at the Zcash website states:
we are not the controllers or the power-holders, and do not control the mining or distribution of Zcash. Every user of Zcash contributes to its decentralization, helping to protect it against failure and corruption.
but the zcash Security Information page reads that:
If we are sufficiently hacked, or if we collectively turn evil, the above resources will not be sufficient to protect you. Luckily, the Zcash network is growing into a larger and more resilient community beyond Electric Coin Company itself. If you suspect that the company has been compromised, please also check other community resources unrelated to Electric Coin Company.
This is slightly confusing to me. I would have thought that the distributed / decentralised nature of it offers enough protection against anyone turning evil. What is the level of control that the
Zcash have over the currency?
