Thanks for asking,
which specific similar projects are you referring to ?
If you talk about CanYa for example, they focus on service by professional companies, such as plumbing, car repair, etc.
If you think about Coinlancer, it is geared towards freelancing for coding projects, etc.
We focus on mini-job type peer-to-peer services, with a special focus on favors in remote locations.
So things that can be completed in a few minutes and are of low monetary value but can be of huge value to the requester.
For example imagine you found a used car in the internet, but it is a 6 hour drive to go check it out.
With Coins4Favors you can hire someone (for example a car mechanic) in the city where the car is offered to go and take pictures, or check it's condition, etc.
Payment is done via Favorcoins in an escrow module, so both parties can be sure the transaction is paid for.
Another example: You saw something you wanted to buy in a store during your shopping trip but could not quite decide.
Two days later you still think about it and decide you want to buy but don't know if the item is still there as they only had one in stock in our size. It is a 45 minute drive there, with Coins4Favors you can find someone who is near the shop, ask that person to go, video call you from there, so you and check it out, reserve it in your name, etc.
Yet another example: You have been on vacation in another country. You bought some local spice which you really like and now it is all used up. With Coins4Favors you can find a tourist who is in the country now and lives near your place to bring some of that spice with him/her when he/she returns.
Here again the escrow function is vital since it ensures the payment is reserved and cannot be withdrawn from the requester.
Final example: You want to call your grandma and say happy birthday to her 80th birthday, but you live in another city. She does not have a tablet, etc.
With Coins4Favors you could find a student who lives near your grandma who would drive there, and offer you to video call his tablet and he could show it to your grandma, etc.
All secured by a transparent rating system for providers and favor seekers.
So in a nutshell we create a peer-to-peer marketplace for small favors around the world which can be requested and done by anyone with a smartphone.
This was difficult before blockchain since the average person cannot accept credit card payments, so compensating people in remote locations would require wiring the money, potentially even with currency exchange fees.
Especially for small mini-job type things, the wiring fee and the trust issue (will the person wire the money after I did the favor or will the person do the favor after I wired the money) is eliminated now with blockchain transfer of favor coins in an escrow wallet.
Does that help ?
