Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.

Symatec's specialists found the way to protect from new ransomware called "Petya" that recently attacked computers all over the world. 

In the moment of attack, Petya looks for C:\Windows\perfc file on victim's computer. If there is such file on the PC, Petya doesn't infect the PC.

In order to secure your PC, you can create this file just using the "Notepad". Also, different sources recommend to create just perfc file, without extension and another recommend to create perfc.dll file.

Yesterday, ransomware called Petya attacked thousends of computers all over the world. It locks victim's PC and demands 300$ in Bitcoins to unlock it.

The Neutrino client allows non-custodial Lightning wallets to verify Bitcoin transactions without the need to synchronize with the full version of the blockchain.

The new release includes such a function as displaying a single balance, which will allow users to see the cumulative number of coins both in the network base and in the payment channels by percentage.
