horizon trustless bridge from eth to harmony (end to end tested uni directional as of now)

can transfer erc20 token to hrc20 token in a truly decentralised trustless fashion as of now.

• [ ] elc //done
• [ ] everifier //done
• [ ] eprover //done
• [ ] hlc //reference contracts added, can be deployed by creating equivalent elc/ethClient/test/deploy.js to deploy to hmy
• [ ] hverifier //done
• [ ] hprover //all the code is there, hmy_getProof does not works, unable to get merkle proofs of hmy txs
• [ ] ethtohmy relayer //done
• [ ] hmytoeth relayer //reference code added
• [ ] cli //done

repos used (code reused/enhanced):

1. https://github.com/near/rainbow-bridge //cli and eth2-hmy relayer code
2. https://github.com/JackyWYX/harmony_rainbow //everifier, eprover, hverifier, hprover, bridge contracts
3. https://github.com/rlan35/ethClient // ethclient contract

development was done sticking to the documentation, clear cut comments added, commit messages explaining clear progress every step of the way,

README.md documentation to run, test, deploy added , sample logs included in horizon/logs folder

@harshabakku thanks for your PR. we will review soon and get back to you.

@harshabakku hey, thanks for your PR. The trustless bridge is still under development, the latest code can be seen here:

• Bridge: #3
• ELC: #2 And some contracts you used are semi-finished.😂

[harshabakku]

good work @peekpi , I understand that elc contracts are semi-finished, and I wanted to submit something that works end-end on testnet so anyone can run my code and further development can continue. but looks like a lot has been developed in last 2 months

to give u an update my code does not really have block provers( validating merkfle proofs of dag entries), it only validates merkle proofs of transaction logs.

also note that I'm happy to help if you want to use my cli, relayers or any submodule of my code.

@harshabakku there is definitely some code that can be used. But the project is still under development and many interfaces will change, so it is difficult to merge them directly.

thanks @peekpi, not a problem at all, (if cant be merged directly)
