BEOS is a chain that is being constructed to join Bitshares and EOS. It is using the EOS protocol meaning that it will have very fast transaction speed. The token, BEOS, is being dropped to Bitshares holders who decide to participate and supporting the system.
There are a number of projects already announced which will kick off over the next year. One is Sovereign Sky which is a satellite based program that is going to run BEOS from space. One of the unique features is that users of the BEOS system are going to be able to chose the jurisdiction they prefer their transactions to be governed by. One option is to allow transactions to come under international law. Space and on the open seas are two areas where there is no jurisdiction from one country.

The first satellite was launched at the end of last year.
Another project is Ruon which is a social media application. Like most other blockchain applications, the "mining" comes from the posting and liking of content. One difference with this application is the business/enterprise focus that it carries. They seek to become the Instagram of business applications.

BEOS is going to provide a bridge between Bitshares and EOS. This will allow any token that is traded on Bitshares to easily convert over to BEOS. There will come a point in time when it should be able to go from BEOS to other EOS sidechains.
The BEOS team decided not to do an ICO. Instead, they are rewarding the holders of Bitshares who opt to participate. This is not an automatic airdrop that is based upon a snapshot of the blockchain. Instead, a gateway is being established by 
This raindrop will last for 89 days. The amount of BEOS is going to mirror the number of Bitshares. The daily payout of BEOS will be reflected based upon how many BItshares are put up each day as a percentage of the whole. 1/89th is going to be distributed each day until the drop is completed.
BEOS is being constructed in a manner to be able to adhere to regulations which could appeal to institutions. Part of the problem with cryptocurrency adoption is the last of institutions involved. At present, regulators are trying to determine how to best allow institutional money to enter this industry.
A blockchain that allows institutions to fully control where the transactions take place could provide the incentive they need to move forward.
