PoSA v1 : Proof of Stake Anonymity

Welcome to the ground floor of a breakthrough anonymous system. In this version we sever the link when sending from person A to person B and therefore there is no solid proof that B received from A. You'll notice in the wallet that there is an extra icon near the minting icon that lights up green when other PoSA nodes are detected. Sometimes a few minutes is needed to find other PoSA broadcasting wallets.

It took no less than 33 builds to get it to this stage, but we're not leaving it there.

Part of the cloak team is already working on a PoSA v2, in which we introduce our "Block Escrow System".

Block Escrow (interestingly an integral part of OneMarket) was drafted in to PoSA to protect senders and receivers from so called "bad actors". What that means is, there is a known risk of a phase 1 node or phase 2 node being a bit naughty and attempting to interrupt the flow of a tx, for self gains or not. It is unlikely that happens but; in our quest for true trustless anon, as laid out on the day we first introduced PoSA we are not ignoring any chances of a "bad actor" disrupting PoSA flow and that concern is now being ruled out entirely.

What we have shown with PoSA v1 is real anonymity and when block escrow is built in, it'll make PoSA the strongest anon system to date (as far as we can tell).

Not only will block escrow make PoSA 100% trustless, we'll be able to provide users with more control over anon sends, to raise or lower the amount of nodes and splits etc but also to remove certain fees that will make a PoSA tx blend into the blockchain even further.

The hard work is completed for PoSA with increased PoSA node stability, various node broadcast checkpoints in place and loads of other tweaks over previous versions in order to get PoSA flow working correctly.

So to recap: In PoSA v1 you now have a working anon right here to play with and test, Cloak team will deliver PoSA v2 in the very near future along with continuous developments of OneMarket and other projects.

Extra command for .conf (optional):

posa=0 Turn posa off, default is on.

Anyone having trouble loading up an old wallet.dat on 1.9.7.33 is advised to make a new one and send some coins over to it.

To send PoSA there is a an Anonymize PoSA check box, after sending once it will stay checked. For normal tx it's recommended to deselect this as using PoSA incurs greater fees for the sender.

The time is approaching when we have to introduce a new tx fee structure for Cloak. As the price of 1 cloak rises the fees are getting more expensive. We'll time the lowering of fees (in which a fork will be needed), with the launch of PoSA v2.

PoSA has been a closed source build, to protect it from cloning but when PoSA v2 launches expect a full audit from cryptographer/s or code analyst/s with the aim of adding an extra level of "trust and authenticity" in our work.
