The slate of active witnesses is updated once every maintenance interval (1 day) when the votes are tallied. They are then shuffled, and each witness given a turn to produce a block at a fixed schedule of one block every 2 seconds. After all the witnesses have had a turn, they are shuffled again. If a witness does not produce a block in their time slot, then that time slot is skipped, and the next witness produces the next block.

It says 2 seconds

The slate of active witnesses is updated once every maintenance interval (1 day) when the votes are tallied. The witnesses are then shuffled, and each witness is given a turn to produce a block at a fixed schedule of one block every 3 seconds. After all witnesses have had a turn, they are shuffled again. If a witness does not produce a block in their time slot, then that time slot is skipped, and the next witness produces the next block.

It says 3 seconds

So which one is correct?

On BitShares blockchain, the block interval is 3 seconds. We might need to update the info on the website.
