Yet another closed source, centralized ostensibly private chat client? If it actually gets a decent user base it should probably be bridged, but otherwise I don't really care.
Exact opposite, based on Monero and Signal code, decentralised by relying on service nodes that anyone can run, implementing it's own onion routing. Honestly, on paper, it looks pretty good.
The core problem is that devs are Australians and can be secretly compelled to backdoor their app via Assistance and Access Act.
HushChat protocol is superior to Session in every way, which relies on centralized servers, Javascript frameworks, and a small set of "masternode" servers to pass your encrypted chats, which is easily Eclipse Attacked.
Cryptocoins which are based on Monero have no protocol-level encrypted data, HUSH is based on an improved version of Zcash Protocol, which does.
HushChat does have some forms of "plausible deniability", such as: It is impossible to tell how many people you are communicating with, it could be anywhere between 0 and 8 people and look like a normal network transaction. Also, every normal network transaction looks like a HushChat, there is no way to tell which transactions are chats and which are not. They all look the same at the protocol level.
Yes, you must pay for your privacy when using HUSH. If you are not paying for your privacy, you are the product, and don't have any. 1 HUSH = 10000 encrypted messages, on average.
