Wang Chun, F2Pool’s co-founder, told CCN that he is planning to upgrade his Litecoin pool to segregated witnesses (segwit), but “it won’t happen in the next couple of weeks.”

We’ll do it on Litecoin first and then make an evaluation if it is feasible on bitcoin.

Litecoin’s F2Pool currently controls around 43{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} of the network’s hashrate. Batpool and Litecoinpool.org are both already signaling for segwit. Combined, around 60{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} of the current network’s hashrate share will likely upgrade.
