Electroneum is a Fast, Secure, Mobile Based Cryptocurrency

This project is the legacy version of Electroneum. Electroneum has since migrated over to a new smart contract enabled blockchain: For details on how to migrate your ETN, please see: Smartchain-Migration

Development Resources

As with many development projects, the repository on Github is considered to be the "staging" area for the latest changes. Before changes are merged into that branch on the main repository, they are tested by individual developers in their own branches, submitted as a pull request, and then subsequently tested by contributors who focus on testing and code reviews. That having been said, the repository should be carefully considered before using it in a production environment, unless there is a patch in the repository for a particular show-stopping issue you are experiencing. It is generally a better idea to use a tagged release for stability.

Anyone is welcome to contribute to Electroneum's codebase! If you have a fix or code change, feel free to submit it as a pull request directly to the "master" branch. In cases where the change is relatively small or does not affect other parts of the codebase it may be merged in immediately by any one of the collaborators. On the other hand, if the change is particularly large or complex, it is expected that it will be discussed at length either well in advance of the pull request being submitted, or even directly on the pull request.

Technical Documentation

Smartchain Migration

Please see our gitbook documentation which explains how to migrate your ETN over to the Electroneum Smartchain.

Some technical information about how the bridge address was created can be found below:

The bridge address spendkey is generated by doing Hash_to_point(v9 fork block hash).-
This ensures that the bridge address is essentially a burn address for which there is no known private key.
The same logic has been used for a coinbase burn address (hash_to_point(hash of v10 fork block: 1175315 )), 
which the remaining miners for this project will mine to. This is required for continuity in the circulating supply 
when we migrate to the smartchain. On the mainnet, emissions are burned from block 1806749 inclusive, 
essentially locking the legacy chain supply at 179,649,469,65.76 ETN.

The bridge address for the mainnet is:


The bridge address for the testnet is:


The coinbase burn address for the mainnet and testnet is:

Vulnerability Response Process

HackerOne is a vulnerability coordination and bug bounty platform that connects businesses with penetration testers and cybersecurity researchers. It was one of the first companies, along with Synack and Bugcrowd, to embrace and utilize crowd-sourced security and cybersecurity researchers as linchpins of its business model; it is the largest cybersecurity firm of its kind. As of July 2018, HackerOne's network consisted of approximately 200,000 researchers, had resolved 72,000 vulnerabilities across over 1,000 customer programs, and had paid $31 million in bounties.
