A defect in B&C Exchange version 4.0.0 has been discovered that will require B&C minters to upgrade to 4.0.1 before the protocol switch date, which will be two weeks after 90% of blocks are minted with 4.0.0 or 4.0.1. Currently, only 21.9% of blocks have a vote for protocol 4.

Version 4.0.1 also has a new RPC called getprotocolvotes that produces the following output:

{

“2.0” : {

“blocks” : 1562,

“block_percentage” : 78.1,

“switch_to_date_time” : “”

},

“4.0” : {

“blocks” : 438,

“block_percentage” : 21.9,

“switch_to_date_time” : “”

}

}

This RPC will tell us exactly when the switch time will be after protocol 4 votes exceed 90%. It was developed solely by Eleven, who just joined us as a developer. Congratulations to @Eleven for getting your first code to the production environment! That was quick!

Download B&C Exchange 4.0.1 for Windows

Download B&C Exchange 4.0.1 for Linux

An OS X build will be published soon.

Finally, it is important everyone make the effort to upgrade. A delay in achieving a 90% vote for the new protocol will produce the same delay in the network’s ability to use the reputation system to vote for and reward reputed signers. Let’s move quickly.
