I'm proposing a DAC which designs, builds, sells, and makes use of sensors to receive input from participants and customers.
For example you could build a fitness app which makes use of sensors which send a pseudo anonymous data feed to the sensor DAC. This sensory information can then be sold to other DACs which need to buy it or it can be put to use by the DAC itself.
For anyone who understands the importance of "Big Data" then you also will understand the importance of sensors to provide input to the autonomous agents which can offer services which leverage "Big Data". This kind of DAC could take on the likes of Google yet remain completely decentralized and private.
Your fitness numbers could be collected and given to the DAC. Perhaps the DAC could even buy it from you. The DAC would then be able to sell this data on your behalf to other DACs. The purpose of this DAC would be to create sensory gadgets and devices, to collect sensory data, and to either crunch the data in ways useful to the customer or sell the data to other DACs which do this.
Healthcare could be revolutionized. The fitness industry could be revolutionized. The gaming industry could be revolutionized. Scientific research which relies on random samples could be a lot cheaper and much more private to conduct.
This DAC would be special. For this reason I recommend a share distribution that 30% go to PTS holders and 30% go to Angelshare investors. The remaining 40% could be distributed via a combination of mining and giveaways to college students in specific fields relevant to developing sensor technology and / or to people voted upon as deserving by majority (PTS/AGS holders).
Additionally this DAC should never be inflationary and the mining period if there should be mining should last approximately 12 months. This would give the DAC a year to fully market and distribute itself through mining. After the mining period is over there should be 0% inflation so that shares are not diluted.
