--U.S. citizen Laws
(ii) Each person shall only participate in the Campaign (a
“Purchaser”) through the personal web account, registered on the
("my.exscudo.com"). If a Purchaser is a citizen, tax resident or
green card holder of the United States of America (“US
Purchaser”), he/she shall not participate in the Campaign except
through such ways as separately designated by the Exscudo OU
for US Purchasers’ participation.


--KYC laws
(v) The Exscudo OU shall be entitled to take any action to identify
any Purchaser at any time, even after the close of the Payment
Window (as defined in Section 7 below). If the Exscudo OU
conducts “know your customer” exercises or any other kind of
customer due diligence to verify the identities of all or part of the
Purchasers, the Purchasers concerned shall timely provide all such
information and meet all such requests as may be sought or
instructed by the Exscudo OU for that purpose.

--AML laws (note that this includes tax evasion/not reporting btc income on taxes)
If the Exscudo OU discovers the purchase of EON by any
Purchaser violating any anti-money laundering, counter-terrorism
financing or other regulatory requirements, such purchase shall be
invalid with retroactive effect and the Exscudo OU shall be entitled
to immediately deny the relevant person’s admissibility to the
Campaign, reject delivery of any EON and request return of any
delivered EON, irrespective of any payment that could have been
made by that Purchaser

--Is it open source?
No, it's closed source. It has decentralized features but is centralized; with centralized governance and decision making.
