[UPDATED]: The OFFICIAL SegWit2x Lock-in Thread

[nibor]

Any reason for BIP91 getting these all these "fans" all of a sudden? It's been having a stratospheric rise no other BIP or proposal ever had...

People don't like chain splits.
BTC1 merged the BIP into their client.
SegWit will be activated through it.

Pick one. They're all true.

What's next? Do we deal with the hard fork in November or is that pretty much unlikely at this point? Sorry if this seems like a silly question, I am still very new to cryptocurrency.

The 2 MB hard fork in SegWit2X is contingent on a majority of miners running the btc1 client. Right now there are only about a hundred btc1 nodes.

And how much hash power is behind those 100 nodes?

About 95% http://bitcoin.sipa.be/versions.html

good article here: https://bitcoinmagazine.com/articles/bip-91-has-activated-heres-what-means-and-what-it-does-not/

It says "This means that after another 336 blocks, a little over two days from now, all BIP 91–compatible nodes will reject any block that doesn’t include bit 1."

then "In that case, BIP 141 should lock in by mid-August, and SegWit should be live on the Bitcoin network after a two-week “grace period” by the end of that month."
What is the difference and why It will take that long? the first one doesn't necessary means that SegWit will actually get activated? It will simply reject blocks?

One more thing, BIP91 should be compatible with UASF right? so running a BIP148 node could work with this SegWit2x or btc1 downloading is a must?

i don't know why BIP141 needs to lock in SegWit again, that part doesn't make sense to me at all but the reason you ask is because BIP141 (unlike BIP91) needs a full difficulty adjustment period which is much longer and about 2 weeks (BIP91 is 336 blocks or 2.33 days)

and as far as i know these BIPs each look at the block versions and need to see the correct one. BIP91 is using bit 4 version and BIP141 (an i think BIP148 too) look for bit 1. so this needs to change.

I think these BIP make us lot confuse about understanding. Previously many people didn't support for Bitcoin split, now I think they are not splitting anymore. So how long it will take for the actually procedure of these Segwit.

[nibor]

So if in a few days miners will start rejecting non-segwit voting blocks, how come some of them are still mining non-segwit voting blocks? If they keep doing this they will reject their own blocks?

Does the bip91 code in BTC1 automatically change the block version to signal for segwit when it activates in a few days?

It's official! What an exciting time to be part of the Bitcoin community.

Wow this is indeed fast huh.
I didn't see this coming but I was just surprised earlier in the morning when I saw the exchange and bitcoin hits $2700 and I didn't know now if I should expect more this coming weekend.
But it seems that the bitcoin community is happy now with the rate. More way to go!

Segwit needs bit 1 to be set by 95% of miners during a 2 week period.

BIP-91 doesn't actually lock-in segwit.  What it does is reject any blocks that don't have bit 1 set.

This means that once BIP-91 activates, all blocks will vote for segwit.  Any that don't will be rejected by 80%+ of miners and so will be orphaned off, and can be ignored.

From the perspective of (non-btc1) segwit enabled nodes, it looks like suddenly 100% of the miners started voting for segwit.

With 100% effective vote, segwit will lock-in and then 2016 blocks later, activate.

They did this since it was safer.  They have tested segwit locking-in using bit 1.

Any node that understands the segwit bit will realise that segwit has locked in, rather than only btc1.

One more thing, BIP91 should be compatible with UASF right? so running a BIP148 node could work with this SegWit2x or btc1 downloading is a must?

You don't need to update your client for the time being.  Using btc1 would mean that your client rejects non-segwit blocks.  The only difference would be that sometimes the core client would say that a transaction has 1-2 confirms and the suddenly it goes back to unconfirmed.  Btc1 should give the correct number of confirms.

The recommendation is that for the time being, you should wait for at least 6 (or more) confirms before considering the payment confirmed.  Even 2 confirms could end up reversed, if they happen to be miners who didn't vote for segwit.

Eureka!! Segwit era started.

Yes, the fears seem to disappear at last. Lets see how much it goes up

Waiting on six (or more) confirmations might indeed be smart in the coming days.  That, of course if everyone does that, will slow down the NUMBER of transactions, but that does not look like a severe problem to me, other than those who need speed.

So, incoming BTC to me will have to wait a little longer to be spent for a little while.  OK.  Big deal.  And as long as SegWit2x is stable and implemented well, we win.

Now people are saying there won't be a hard fork anymore hence the splitting off of the blockchain.

This is very confusing and the timeline of when this was sposse to happen is drawing nearer with less than two weeks left to go.

[s8ndo]

Does does this mean no split on August 1st? and BTC will be safe in online exchanges?

[Dr Bloggood]

Congratulations bitcoin! Relieving that this part of the drama was solved. Hehe, https://www.xbt.eu is down, guess a lot of people are trying to access it. Remember who said it first, over $3500 before aug 5, then downwards correction again.

Edit: Up again, apparently modifications were made

Will remember that. We will see how close you were with your guess. 

I wouldn't dare to make any prediction right now. Except that the trend will be UP in the coming months.

As recommended before you should get your bitcoin off exchanges, Coinbase, etc before July 29. This post explains some things that could go wrong with BIP91. There is also the possibility that Bitmain may go ahead with their hardfork to Bitcoin ABC on Aug 2.

It seems we are not done yet. There is still a danger ahead. We better stop celebrating and prepare for the next level.

Jimmy Song just posted an article about the possible dangers:

He basically says miners still can betray the NYA and fuck everything up.

Sure. They will ensure the sentiment for the 2x is getting done as well.

No breaking. All good.

This is getting business style, get ready man or do you want to stay ranting nichy all time?

I'm hoping that we don't have a hard fork...I would really prefer not to split off into 2 or more versions of bitcoin.  I have been using bitcoin for a number of years, but I still have to admit, a lot of these scaling options go way over my head.   I definitely agree it needs to be scaled to be ready for a ton more transactions, but when people ask me about the different scaling options, I have no idea how to explain it to anyone

Hey Segwit!

How does it feel to get activated? Pretty cool, isn't it?

[bitty]

If I have my btc stored on my electrum wallet will I be safe from a split? Or should i go with paper?

[bryant.coleman]

229 Blocks still remaining in the grace period. But I am surprised that around 7% of the blocks are still being mined by the pools which does not support BIP 91 (the latest being block number 476890 mined by Bitcoin Russia). Will they continue to do this even after the grace period? In that case, they will lose all the coins they mine, right?

You are safe when you own the private keys to your Bitcoins. Because when the fork happens you can choose which chain to claim coins on.
