One option to look into could be a danish K/S. Its similar to a UK LLP in many ways.

The liable partner is usually set up to be a limited liability company, so no one is personally liable.

It is not taxable in Denmark, meaning that all token holders will be responsible for for reporting it in their home country. That way double taxation is avoided and there will be less administrative duties for Inchain.

Owners with less than 5% share are not required to be registered. The easiest way of doing this would be to whitelist addresses with more than 5% of the tokens before allowing them to vote. That way you can choose to register or split your tokens in to multiple addresses and stay anonymous.

Of course you would still need to submit annual reports and so on but it might be worth looking it to.
