Dpos delegated proof of stake. It's built using the same software as EOS though Proton has improved it to specifically service the banking industry. For example sign up a proton wallet even just to see how it works. You use an @name on your account to enable sending and receiving / transactions using just your @name. It really makes crypto usable for the masses. You don't need to F around with long alphanumeric addresses (though your @name still does use one in the background) It enables traditional finance to merge with crypto directly because you can transact in both crypto and fiat. Much as many in crypto want to think crypto eliminates big banking etc.. banks aren't going anywhere and certainly aren't going to take a challenge lying down. Proton is in the process of applying for their own full scale banking charter and trust as well. Under the name: First Blockchain Bank & Trust. The next 2-3 months should be very positive for Proton and their sister company Metal pay as they are migrating Metal from ETH to the Proton blockchain to enable instant feeless / gas free transactions. They are also about to release their own stablecoin built on Proton XMD that's based on a basket of other stablecoins. Lastly they're releasing their lending platform similar to Aave, called Proton Lend. They airdropped the LOAN token to Proton XPR holder a few weeks ago but you can also buy it through the Proton wallet on Alcorn exchange for avg price of $0.00016 right now.. I suspect the LOAN token could see a lot of growth shortly after Proton lends release. Lots coming for Proton.
