Yesterday new users of one of the most popular cryptocurrency exchange Bitfinex had faced unexpected issue with registration. Now in order to create an account, new users need the "invitation code".

As you can see on the screenshot above, there isn't a lot of information what is "invitation code" and where should new user get one. On the Reddit thread even users with old and active accounts aren't able to find a code to share with a friend. 

There are no invitation codes. Bitfinex is probably trying to halt all new registrations without publicly saying as much. Given the other dodgy things of late (warrant canaries, withdrawal minimums), it might just be that they're about to get shuttered. FBI? FINCEN?

It is worth noting that there is no information on the new registration rules in the official Twitter account. 

Registration and account validation on any of the cryptocurrency exchange is not an easy deal at all. For example, at Poloniex, you need to provide the scan of your ID and and a clear photo with you, your ID and "Poloniex" on the piece of paper. And photo must be 100% clearly visible.

Another popular exchange called Bittrex decided not to bother itself with "invitation codes" or collecting photos of new users. They just stopped new users' registration five days ago and still hadn't open it again. 

ZCash “Overwinter” sets the Base for Further Developments

The first hard-fork of the privacy-centric protocol Zcash will be held on June 26, 2018: the upgrade is named “Overwinter” and takes place at block 347,500

As declared in Zcash Foundation`s post on the development, the hard fork is to strenghthen the protocol for additional upgrades to the network, for instance replay protection, versioning, a transactional expiry feature, and as yet undetermined changes.The customers will be demanded to install the upgrade after the software is carried out.

The protocol assists for seamless network updates in the future, such as the much-awaited Sapling protocol designed to raise network scalability and speed. Zcash claims the forthcoming update is well-gained by significant third parties like Binance, Gemini and BitFinex, who will “substantially support” Overwinter.  The foundation is also continually reviewing the list of third parties as the entities confirm their involvement.

Theoretically, the network risks a blockchain split if any members of the community disregard the need to update the system and keep on with the old versions of Zcash. While Overwinter is low on features, it is important to the broader network strategy as further capabilities depend on the Overwinter update. 

It`s worth to note that the friction is already happening in some places. On June 20, 2018, D. Jane Mercer, the developer of the ZCash Windows wallet, WinZEC, threatened to stop all coding activities as the network the Zcash Foundation failed to fund his work. The community members nevertheless promptly donated funds to his wallet address.

For miners running Zcash nodes, the official software has been updated to automatically update to the latest software after block 347,500 is mined. However, if automatic updates are disabled, miners stand to can miss the new code. Zcash Foundation asks the users to abstain from using their wallets at least an hour before the scheduled update.
