ERC725: self-sovereign identity standard for ETH released

Ethereum developer Fabian Vogelsteller creates Ethereum Request for Comment 725 (ERC725) on GitHub
12 October

Ethereum developer Fabian Vogelsteller created Ethereum Request for Comment 725 (ERC725) on GitHub. Despite the fact, that the project doesn’t even have an assigned Ethereum Improvement Proposal number, within 24 hours, the plan for a standardized identity system for humans and machines gained significant hype.

On GitHub, UX designer and fellow Ethereum Foundation member Alex Van de Sande called the ERC “very useful,” while suggesting some adjustments.

In an email to, Vogelsteller explaines, that “identity is certainly one of the most [important] missing pieces in the blockchain ecosystem". According to the creator, ERC725 solves quite a lot of problems. 

“This needs to be standardized so that other contracts can interact with real world identities, automatically check and verify them. It’s not mainly necessary for interfaces alone. Also, this contract represents ONE identity. The addition of claims needs to be standardized, so that other identities can issue claims about each other.

As the man views it, crrently everybody collects all information about you separately to make sure they know who you are (e.g. banks, credit services, or any service which needs to have KYC). A standard will help insofar that everybody can auto check certain claims, and therefore don’t need to store actual details about you anymore, as they - as long as they trust the claim issuer – don’t need to have the actual information. The current over-collecting is because of lack of a better system.

On October 12th, Fabian Vogelsteller is to present ERC725 at the Ethereum London Meetup. What the future has in stock for it, remains to be seen, yet is is definitely worth monitoring.

Ethereum network is still unstable

Byzantium had executed on Monday, but developers aren't ready to call the software transition complete
18 October

Organizations and developers are better off refraining from launching large projects until the Ethereum network is fully stable after the recent Byzantium update. This is said by the Gavin Wood, Parity Technologies head and reported by the Coindesk.

Since new versions of the software were released just days before the fork, much of the network has not yet been updated. So, at the time of press, slightly more than 25% of Parity customers updated, in Geth this indicator is slightly higher - about 59%. So, in total, the update was made about 45% of the network.

Another aspect that should also be taken into account is the short time for testing. In particular, the developers recalled previous versions of the software, discovering critical errors that could make the network vulnerable to DoS attacks or lead to incompatibility between nodes and, as a consequence, network sharing.

Therefore, the question of how safe the network is at the moment is fully justified and, taking into account what has been said above, remains open. This is exactly what Gavin Wood warned, recommending at this stage to refrain from launching large-scale projects.

In addition to the nodes that have yet to update, there is also a possibility that in the current Byzantium software there may be bugs that endanger the security of the Ethereum network. The most dangerous among them is a bug of consensus, in which nodes can not communicate. Its result can be the separation of the block-man into several incompatible chains.

As far as is known, at the moment developers are conducting extensive tests, trying to detect such bugs before they are active. As Gavin Wood says, if the network does contain such a bug, it will take several days to prove itself.

I don't think anyone believed the network was going to self-combust on block 4,370,000.

The head of Parity Technologies is also convinced that if problems are discovered, the Ethereum development team will quickly release new updates designed to prevent any harm to the platform.
