If they're UTXO based, that means payments are exactly as traceable as they are on BTC, which means chainalysis-style tools are usable on the network.
I found the MobileCoin white paper here.
It doesn't appear to use traditional consensus mechanisms like Proof of Work or Proof of Stake, instead hoping to achieve byzantine fault tolerance by utilizing SGX secure enclaves.
There isn't a lot of technical detail in the whitepaper about how this is achieved, but there are several references to their use of Stellar Consensus Protocol for how consensus is achieved.
Stellar's website has technical documentation here: https://www.stellar.org/papers/stellar-consensus-protocol?locale=en
Again, here's the white paper on Stellar Consensus Protocol, which goes into the arguments for it over proof of work and proof of stake, as well as some of the technical reasons why they say they're byzantine fault tolerant.
Bottom line, cont'd: This move toward pseudo-privacy is consistent with Signals moves in the last year that have claimed privacy, but belied that aim.
@rizzn Samourai only if you run your own node, otherwise you're doxxing your xpub to their servers. Do you have any recommendations for monero wallets that are FOSS and don't suffer from network privacy leaks?
