Spam attack
On July 22nd 2017 an attacker spammed the Burst network with messages, causing wallets to crash and splitting the network into multiple forks.
The network remained unstable for several days. On August 11th 2017, in the aftermath of the spam attack, a new development team called the PoC Consortium introduced itself on Bitcointalk.org.
They have been recognized by the former development team as the designated successors for the Burst Reference Software.
