Segwit is now locked in on testnet.
What does that mean?
are we having a hard fork for the segwit?
No hard fork.It means its running successfully on a testing/closed envoirnment.
just said Segwit will very soon？
Yes hopefully soon.
Segregated Witness and CHECKSEQUENCEVERIFY are now both enabled on testnet, blocks are minting and transactions are still sending as expected.Once testing is successful then all will be pushed onto the public github repository and new clients will be released.
