Excuse me, Phantom is same with Zeronet.... Whats newly functions
plus, Sia Coin is cload storage.. is sia hosting files?
Since PHANTOM is a port of ZeroNet there are similarities, but at the same time we are also extending that functionality. I'm not the best person to talk about the in-depth technicalities but someone else from the team might come by and give their opinion.
I don't know much about SIA, but they are serving a different niche than we are.
ZeroNet is not Phantom, but Phantom is ZeroNet. And much more.
Currently we have written about 800 lines of working python. Once we are done with Phantom it will be a few thousand lines of code. The implementation we are working on is unique, no one is using anything comparable yet. Our vision is to build a fully fledged decentralized and distributed web hosting network, which will be capable of running any kind of website (client side js, html, css etc..) able to interact with SHIFT (and Ethereum). This gives us the possibility to build a working economic system where we can "pay" users (instead of the hosting/vps providers) to host content via node rewards.
Furthermore, right now all frontends of ethereum dapps run on centralized servers, often a single web server with node-js as a server side backend. Sometimes along with databases as well. We enable frontends for all SHIFT / Ethereum DAPPS to be run fully decentralized in a secure manner. The frontends can not be taken down, are immune to DDoS/DoS attacks, are immune to single-point-of-failures or power outages. And the best of all, it does not cost any hosting fees what so ever as users serve the content for each other.
It is secure because all calls that are made are done via IPC, on localhost only. When you browse a site, you sync it locally and then execute the local IPC calls. A site is never browsed over "internet". This means that you can run a GUI frontend, in this case ShiftHub, which will host wallet, DAPP browser, messaging services, the functionality to easily create custom websites with just a "click" and integrate it with SHIFT.
It also will serve as a decentralized storage system, although the limitation at first will be 10MB per website + contract storage (which should not contain more than a few bytes,). The contract storage will act as a decentralized DNS system for Phantom among other things. An easy way to describe it is that we are trying to build a parallel Internet for decentralized content distribution.
We are building our own "web 3.0" for Phamtom, although you can't really compare it.
