Ce site raconte n'importe quoi, segwit n'est pas activé, il est en train d'être locked-in, et il sera techniquement locked-in, au prochain block multiple de 2016 à savoir au block 479808, puis activated 2016 block après, au block multiple de 2016 suivant, à savoir au block 481824.
Ici ils ont l'air plus serieux :

Un peu plus de précision sur le planning Segwit2x prétendument lancé et utilisé par 80% des mineurs ... (c'est pas ce que je vois dans le marqueur SegWit sur le réseau Bitcoin justement) :
https://medium.com/@jimmysong/segwit2x-what-you-need-to-know-about-the-2mb-hard-fork-27749e1544ceWhat can we expect?
The easiest way to think about what will happen is with some rough dates:
July 21 — Segwit2x is due to be released and presumably all participants to the New York Agreement will run it. The miners currently signaling “NYA” in their coinbase transactions, or about 87% of the last 24 hours’ worth of blocks, are a good estimate of blocks that will mine using Segwit2x.
July 23 — BIP91 should lock in (requires 80% of 336 blocks to signal)
July 26 — BIP91 should activate. At this point, all blocks are required to signal for Segwit (BIP141) or they will be orphaned off the network.
Around July 26–27 — This is also around when we can expect a new difficulty adjustment period to begin. The last one as of this writing was June 17 and they typically take 12–14 days (closer to 13 since new hardware comes online constantly). So June 30 (block 473760), July 13 (block 475776) and July 26 (block 477792) seem to be the next 3 difficulty adjustment period starts.
August 10 — This is around when we can expect block 479808, which is the end of the difficulty adjustment period. Very close to 100% of blocks in this difficulty adjustment period should be signaling for BIP141 (Segwit). As this is above 95%, Segwit should be locked in.
August 23 — This is around when we can expect block 481824, which is when Segwit should activate. From this block on, Segwit transactions will be legal on the network. This also sets the activation date for BIP102 on Segwit2x to block 494784 (exactly 144*90 blocks later).
November 18 — This is around when we can expect block 494784, which is when Segwit2x should hard fork to 2MB blocks.
