Add Ethereum Classic Support

[ProphetDaniel]

Transaction price in forked Ethereum kills some applications of the technology because of the current coin quotation. Ethereum Classic can be rather used to make sure smaller transactions are still viable. So adding it will greatly increse LETH user base.

Do you have some public full node with API available like this:
--shh --rpcapi "web3,shh,eth"

let us know that we could make some test

[ProphetDaniel]

Try this https://mewapi.epool.io

[ProphetDaniel]

I prepare this node today: https://ethereum-classic.herokuapp.com/api.

[hacktar]

What is the best way to identify the blockchain classic mainnet?

[ProphetDaniel]

You can issue the following command:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x1d4c00", true],"id":1}' https://ethereum-classic.herokuapp.com/api

So that you will be able to compare with the same block for forked Ethereum network. There should have a better way to identify though.

Because the node is still synchronizing with the network, that will return a null block. It will start working after the node synchronization has accounted for the DAO hard fork block number.
You can check synchronization by:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' https://ethereum-classic.herokuapp.com/api

@hacktar The epool api is the same used by MyEtherWallet. You can always contact @EtherNinja for that.

[ProphetDaniel]

@ChuckSRQ for LETH the API endpoint needs to have whisper protocol enabled by default. As far as I know neither myEtherWallet nor epool have whisper enabled right now. It would be cool to see both activating it though.

Hosting geth nodes require substantially more resources than parity. There is currently no plans to deploy geth for mewapi as a free service.

[hacktar]

we will wait for sync on https://ethereum-classic.herokuapp.com/api node.
You could just add this host on Settings of LETH and use chat over whisper but to manage asset we have to make some changes to network identification and wait for last block sync.

is syncing and works

@hacktar, if you compare Ethereum Classic block #1,920,000 with Forked Ethereum block #1,920,000 you will notice that both have the same parent hash but different hashes because that is the block in which Ethereum foundation executed the fork. This means you can identify Ethereum Classic network with the hash of the block #1,920,000:

• 0x4985f5ca3d2afbec36529aa96f74de3cc10a2a4a6c44f2157a57d2c6059a11bb for forked Ethereum
• 0x94365e3a8c0b35089c1d1195081fe7489b528a84b22199c916180db8b28ade7f for Ethereum Classic

just in case, we should also consider using the chainId API which is more explicit for ETC and other forked chains, here is the EIP we are proposing

[hacktar]

Done. Please use a synced host node with API for whisper messages
