Following the Block Producers [BP] elections, the EOS Mainnet faced a technical glitch on 16th June due to which the Mainnet was halted. The entire community was asked to shut down all the nodes and downgrade to version 1.0.3. All the BPs, along with the Block.One team worked on this issue and has been providing constant updates on their progress.
 One of the Telegram Channels named “Mainnet Status” also broadcasted all the instant updates regarding the same. The team also mentioned that the root cause of the issue was due to how deferred transactions were handled.

Following are the steps taken by the team to fix the issue:
 A nodeos fix will be released
The block producer nodes will be upgraded
Blocks will be replayed until last irreversible block
Block producers will sync to each other
Chain will be opened up for mainnet and has been upgraded to version 1.0.5, without losing any data on the blockchain.
 The fix was released by Block.One on GitHub and has been verified by the Block Producers and Standby nodes. At 14:48 UTC, the blockchain went live and the firm released a statement which summarized the entire bug fixing process. The statement was published in English, Chinese and Korean by the Block Producers.

Something in eos lately has a lot of bugs and errors. It seems to me that the price has fallen so strongly against this background. Maybe early launched their network?
