⚙️ NEO network spammed with free transactions

NEO ($NEO) was attacked with free spam transactions on Friday, July 27th, 2018, resulting in full blocks, a slow congested network, and a temporary halt of Switcheo exchange, NEON wallet, and Effect Force platform. The spam appeared in the form of empty invocations which allowed thousands of transactions to be submitted without any actual transfer of funds. It is currently unknown whether the attack was malicious or caused by a bug in a contract.
