My question to Signal is: there are a lot of cryptocurrencies that already have significant traction - why not integrate with them rather than a brand new one that has to start from scratch building an infrastructure?
MobileCoin uses a fork of the Stellar Consensus Protocol, which is a consensus protocol that by design, relies on a small set of trusted third parties to establish consensus.
This does not give it highly credible censorship resistance, yet MobileCoin was chosen as the sole cryptocurrency that Signal is integrated with. Why?
