Update: This campaign is closed, and I’ve developed a new Swarm Redistribution contract, which has lower gas costs,
https://gist.github.com/resilience-me/1500caf64411db16e375630dfc17b1ea
I built a crowd-funding campaign for project Resilience. It’s swarm redistribution except I am the only human in the system. It’s a chance to try out the dividend pathway idea, and to experience how a smart-contract on Ethereum can be used for “programmable money” and for building a Swarm Redistribution system.
https://etherscan.io/address/0x95c2906debbb9203ff7007f26c2f00a936c77b5d#code.
buyViaJohan() lets you exchange ETH for RES, and also creates a dividend pathway from Johan to you. You can then transfer that RES for your payment, and the receiver can exchange it for ETH without exchange tax, or continue to use the RES within the Resilience system, growing dividend pathways each time it is exchanged which, if Johans account is connected to the dividend pathway web, pays tax to his “Resilience Foundation” and funds the project.
To view the total “basic income” which Johan has received, look up totalBasicIncome[JohanNygren]
Transfer(), buy(), sell(), and buyViaJohan() show up as events, which you can see if you use Ethereum Wallet.
Ethereum wallet mis-calculates the gas costs, so add a bit of extra gas per transfer.
Ethereum has a gas limit, and so, there is a limit to the size of dividend pathway swarms which the swarmRedistribution() function can handle. This poses no risk to those who hold RES, as the sell() function can always be used to withdraw RES if an accounts swarm reaches a max-size.
The smart-contract is not entirely bug tested, but as long as sell() works, then it should be risk free, except for the gas cost for sell() which is roughly 0.005 ETH. Below are a few public tests, done on the Ropsten test net.

Update
Had a typo in the closeCampaign() function. Have updated that, published a new SwarmRedistribution contract, and updated the link at the top of this post.
The old contract is available on https://etherscan.io/address/0x8e66ffe69b3f8d78f2a696e40c02f7454c0a01d9#code
Update
Another bug fixed. This one risked loss of ETH.
I have closed the previous contract with closeCampaign(), and deployed an updated one.

Update
First buyer of RES, used buyViaJohan() to form a dividend pathway from me to them.

Update
changeJohanNygrensAddress() breaks the contracts predictability since its possible to change address for the human account. I’ve updated the contract and removed that function. Here is the new one https://etherscan.io/address/0x95c2906debbb9203ff7007f26c2f00a936c77b5d#code.
The previous one is now closed, and only sell() can be called, the isOpen modifier will cause a throw on the other functions.
The RES holder which had 2 RES has withdrawn their RES,
