EDNA is certainly one of the most fascinating and far reaching projects on EOS. Their goal is basically putting DNA on chain. It had gotten a lot of attention via the airdrop, but since then it has become a bit quiet about them.
Now they have launched a brand new site, that aside from the white paper, gives a lot of new information about how this project is intended to operate:

To get the basic of Edna, i recommend you to watch Matt "Costa Rica Crpyto's" interviews with founder Greg:
To me the major takeaways of the new website are the following:
1) Technology & Lab Setup: They have a plan about how to economically and logistically sequence DNA and put it on the blockchain, which, according to Greg, should be affordable to the average person.
2) DAC: The Dac is the participating community, not just EDNA token holders, representing "every genome" on chain, which currently is equivalent to accounts (as there are no genomes on chain). A very democratic approach. The DAC will be in controll of all operations of EDNA, and will appoint custodians, to handle everyday business.
3) EDNA token: As stated above, EDNA is not supposed to be a base vor controlling the DAC. But it's the base for rewards, generated from research. Here again, the token alone is not that powerful. Greg's proposal gives a 1:1 for simple staking, 2:1 for staking and a 10:1 reward if ones DNA is used for research, so its a lot about personal investment.
