I am excited to be able to announce the 4.0 release of B&C Exchange. It contains major protocol changes centering around the reputation system for signers, which is fully functional in this release.

We have implemented protocol voting in B&C, so when 90% of minted blocks have the upgraded protocol, the two week countdown to the actual protocol switch date will begin.

Once the switch occurs, shareholders will begin using the reputation voting system to elect reputed signers. @TomJoad has already indicated he will seek to be a signer. I am very interested to see who else will seek to become a B&C reputed signer. For those who are interested in becoming a signer, here is a summary of how to do that. Additional details can be found in the B&C Exchange design document.

Until now, active participation in B&C Exchange has been mostly restricted to developers. This release will change that as shareholders vote for reputed signers and reputed signers work with developers to bring B&C Exchange to full functionality in a 5.0 release.

I’m excited to be able to see the reputation system in action in just a few short weeks. I expect we will see quite a bit of discussion in the community about the reputation system and reputed signers going forward.

Here are the builds:
