User Story Oraclize is a leading oracle service provider for smart contracts and blockchain applications. Currently there are no oracles for smart contracts on EOS or Telos platforms.

Why Is this Needed Oracles are essential for a number of applications from generating random numbers to verifying if your sports team won. Getting data from an outside source on to the blockchain is an essential and desirable feature.

Description Type: Oraclize integration with Telos

Definition of Done Build a random number game similar to Ether Flip An user should be able to interact with the smart contract similar to Ether Flip or Cryptobets. You can deploy the contract on testnet Scatter integration is needed for user to interact through a website

How much of a front end are you expecting for this? A random number game seems fairly straight forward, but as etherflip is an example, are you expecting a way for people to play it online?

I have not heard of telos before, but I am having a hard time finding a way to deploy to their testnet? Do you have any info on that?

I have some other work this week. If no one has picked up this bounty by next weekend I will try take it.

z-meta commented 6 years ago

Frontend can be a simple website like https://cryptobets.cc/#/

Telos is based on EOSIO software --- if it can be deployed on EOS testnet, it can be deployed on Telos testnet.

I will ask some help from Telos technical team in terms of how to deploy contracts on to Telos testnet.

From a user perspective, I should be able to place a bet from the web interface using Scatter and I should get some notification about whether I won or lost and if I won, I should get the prize tokens from the smart contract.

Great, thanks that helps a lot.

@jschiarizzi we have a telegram channel at https://t.me/TelosTestnet where we can help you with anything you need. Let us know there or here what difficulties you have, I'll try to keep an eye on this issue, but there's quite a few more folks over on the telegram channel that can offer help.

z-meta commented 6 years ago

Scatter is the way to sign transactions and for users to interact with the blockchain. You can think of Scatter as a better alternative to MetaMask. https://get-scatter.com/

cupOJoseph commented 6 years ago

I'm looking more into this to decide what is possible / best strategy. I'm not accepting the bounty quite yet since I'm not super familiar with EOS (mostly a solidity person) so I have to see if this is within my scope first (if someone else wants to take this bounty feel free 😄 )

Oracalize says it's compatible with EOS testnet jungle right now, so I'm looking at those docs as an example. I'll ask in the telegram for some help, thank you for sharing.

z-meta commented 6 years ago

Great! Look at the comments earlier by @jschiarizzi

Telos is a fork of EOSIO code and I received a message from Thomas Bertani from Oraclize stating that they are very close to releasing an official integration with Telos.

Oraclize is already integrated with EOS --- http://docs.oraclize.it/#eos

All that would be required now is to build the frontend.

Let us know how we can help or ask any questions you have on Telos Testnet Telegram channel

Good luck!

I finally got a telos node working! telos works

@nanspro you have until tomorrow to update. Otherwise I'll assume you are ghosting on us and I'll ask for you to be removed from the bounty. I can do this if you are not working on it, I'm halfway there already with getting Telos running.

nanspro commented 5 years ago

sorry for leaving this in the middle, i got some work suddenly hence was not able to give proper time. Go ahead @jschiarizzi i am leaving this task.

cupOJoseph commented 5 years ago

Great, I will do the logic and get it deployed on Telos this evening (definitely by this weekend) and then do a little front end early next week.

I got the simple EOS example from oraclize running, next is deploying this and testing on Telos. And then adding a little coin flip app to it

z-meta commented 5 years ago

Excellent work!

All registered as a producer. not sure if that's needed to submit a contract, but I'm connected regardless

cupOJoseph commented 5 years ago

Talking to Jesse now about the last 2 things to implement:

making the function be able to process Telos tokens. I haven't done that in an EOS contract before so I just have to figure out how and test it a bit.
Connecting the front end with Scatter, and make sure it works with Telos.

rmshea commented 5 years ago

Hey @jschiarizzi, any updates here? 😄

cupOJoseph commented 5 years ago

I've got a contract for accepting funds that works with Scatter. I fell way behind and didn't integrate it with my Telos Oraclize contract at all. Can't believe I let this issue get away from me for this long.

cupOJoseph commented 5 years ago

2 has a little contract for managing funds, and another for coin flip betting with telos. Haven't integrated. I'm not sure how really, or how to test on telos. Maybe someone else could deploy it and test? The code is in there to use if someone else wants to finish this fast than I am
