Taproot proposal

[cygan]

yay 💪👌

Yesterday was the first full day with over 90% Taproot signalling blocks!

https://www.reddit.com/r/Bitcoin/comments/nj1z6o/yesterday_was_the_first_full_day_with_over_90/

in addition, taproot.watch has now created a stats, in which you can better represent the signalling
https://taproot.watch/stats

[fillippone]

Nice addition to taproot.watch

They now added a "Stats" tab where you can look at the graph of Taproot activation percentage:



We see percentage hovering around 90%.
This bode well for next period, with all. the known caveats about how this website computes the harshpower!

[nibor]

If their last block was a signalling block their 10% is included (so jumps to 94%) if their last block was not signalling they are not included so rate drops to 84%.

I think BTC.com said on twitter they should be signalling full time by end of this week. Assuming they do then is a dead cert for next period - otherwise will be very tight!

Looks like we are there! 

BTC.com has signalled with all of their last 7 blocks!

So assuming no miner changes their mind will lockin around the Sat 12th June.

Yes, but as I checked it recently, the percentage is now over 96%

I noticed Rawpool are signalling already, also most likely that BTC.com are fully signalling.

[fillippone]

If the daily average continue to stays above 90%, taproot should be locked in on next period (about 18 days).

It would be important for the bitcoin community (whatever this means) to see universal supporto of a non controversial upgrade, while other subjects propose controversial agreements on different topics.

I request immediately gmaxwell and achow101 to address the following concerns regarding taproot:

Citizens of the United States of America pushing very hard for taproot, they go far as straight lying: https://twitter.com/adam3us/status/1396888227538145294

Neither this period nor the previous period reached 90% but in the USA everyone is celebrating the taproot lock-in.

Why I have that feeling that Bitcoin price is plummeted not because of Elon Musk, but because of Taproot?

People in the USA celebrating also that in China miners having a bad time, so how the hell they can celebrate taproot lock-in when those who signals the majority are Chinese miners.

I don't even wanna mention Foundry USA and Blockstream.

The moderator on this board achow101 is the main person who spreading fake news online regarding taproot.
 

You seem to be misinterpreting.

We now have ~95% the hashrate fully signaling for Taproot, so Taproot should lock in during the next signaling period.

.

No one is saying it has locked in already.  They're saying we're on course to achieve lock in next period.

[nibor]

No one is saying it has locked in already.  They're saying we're on course to achieve lock in next period.

And technically even after it has locked in we have to wait till November before the 1st tx's and so the 1st Blocks with it in.

Up to that point if a majority of the miners downgraded (or never actually upgraded - just signalled) it would not manage to actually maintain the longest chain so if someone published a currently valid tx that was invalid under taproot we would have a chain split... (I think I am right on this?)

So if you enjoy a good conspiracy theory can run with that scenario... which really would be chaos... BitcoinCash/SV all over again but with Core having the lower hash rate - and nobody maintaining longest chains codebase!

[gmaxwell]

The purpose of the delayed activation is to give plenty of time for everyone to upgrade.

Bitcoin doesn't follow the longest chain, it follows the longest valid chain-- and at least to upgraded parties any taproot-invalid chain wouldn't be valid.  So the idea is that it doesn't even matter too much if such an invalid chain is created, as it'll just get ignored and the effect would just be some hashrate vanishing (until the losses cause them to wake up and fix their stuff ).  And this holds no matter how much hashrate there is...

Of course, parties who aren't transacting and are asleep at the switch might not have upgraded but if they're not accepting transactions in realtime it doesn't much matter what chain they are on.

So I think that really takes the wind out of the chaos conspiracy theory.   But it's a good reason to get major exchanges and other influential parties that accept a lot of payments to confirm that they've upgraded prior to activation.

Also, "someone published" isn't sufficient.  Pre-taproot nodes (and miners) will not relay or mine taproot spends.  So the only way a block could be created with an invalid spend in it is if some miner intentionally did so (or at least lobotomized the protection out of their node), even if their software wasn't upgraded.

Pre-taproot nodes (and miners) will not relay or mine taproot spends.

I forget the detail of backward compatibility, so i'll just ask it. Why pre-taproot won't relay taproot-transaction? Is it because the transaction missing witness and the (empty ?) script automatically treated as valid script?

There's nothing missing in the transaction, thanks to segwit. Versions 1-16 segwit are non-standard for older clients, hence not relayed. Version 1 segwit would become standard for newer clients (0.21.1 and up) after block 709632.

Pre-Taproot nodes that support SegWit see the new witness version (version 1) and because by default they have a flag acalled SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_WITNESS_PROGRAM that acts as a standard rule and makes the node reject any transaction containing version 1+ that comes to their mempool. This flag doesn't exist when verifying blocks so they don't reject the transactions but they also don't verify everything about the said transaction.
After Taproot (core v0.21.1+) they will do the same with witness version 2+.

[gmaxwell]

Pre-Taproot nodes that support SegWit see the new witness version (version 1)

That is all correct, but I wanted to point out that the taproot spends are also non-standard under prior releases (e.g. even without segwit), just since your description might have made it sound like they weren't.

Is anyone really surprised to see that Marathon pool is the only one not signaling for Taproot activation?
I am not surprised at all, but problem is they are growing in hashrate with their new 73,000 miners starting to run in Texas with plan to have total of 103,000 miners with 10.36 EH/s hashrate.
I really don't know what to expect from them after ofac compliant ''clean'' blocks...

[Charles-Tim]

I like the recent change that is although not actually any change but just a way to make the result more accurate. The signalling blocks is already 90% but the lock-in is when 1815 signalling blocks are mined. I did the ratio and it is appropriately maximum of 90% signal block that could contain in 2016 blocks. So, it do does not necessarily mean when 2016 blocks are mined, it is when 1815 blocks are mined.

1815/2016 * 100 = 90.02976190476190%

Which is ~90%

Reaching 90% is not indicative of a softfork lock-in. 1815 blocks within a period have to signal for the Taproot softfork to lock in.

It is still very possible MARA Pool will signal. Even if the pool does not signal, it will not affect the softfork lock-in, provided if other mining pools continuing signalling. Currently at 98.33% when 60 blocks have been mined, only one block did not signal which is from MARA Pool. MARA Pool mining hashes is insignificantly in relation the the lock-in if others Pools continuing signalling.

i am not surprised but not because of their clean block nonsense but because they are running a very tiny mining pool and from what i remember from last soft fork we had the tiny pools are not going to signal until the very last moment.

They might not be actually a “friend” to Bitcoin. Here’s also something the company had done in the past, that should raise some concerns on who these people really are.

https://en.wikipedia.org/wiki/Marathon_Digital_Holdings

Marathon Digital Holdings (formerly Marathon Patent Group) is a patent holding company that is the parent of Uniloc, known as a patent troll company. Marathon purchased patents related to encryption in the 2010s

Better because agreeing 100% is never a good thing.
Anyway, whether they signal or don't, who cares, we don't care.
They're bound to have to adapt to taproot and then I'll be really interested to see how taproot will make life difficult for them on the privacy side.

Apparently, Marathon is going to signal Taproot Activation:


https://twitter.com/michael_saylor/status/1399407493839732744?s=21

From Marathon Press Release

“Marathon is committed to the core tenets of the Bitcoin community, including decentralization, inclusion, and no censorship,” said Fred Thiel, Marathon’s CEO. “Over the coming week, we will be updating all our miners to the full standard Bitcoin core 0.21.1 node, including support for Taproot. By adopting the full standard Bitcoin core node, we will be validating transactions on the blockchain in the exact same way as all other miners who use the standard node. We look forward to continue being a collaborative and supportive member of the Bitcoin community and to realizing the vision of Bitcoin as the first decentralized, peer-to-peer payment network that is powered by its users rather than a central authority or middlemen.”

hahahaha

Are they going to just temporarily behave well or go back into dumbass mode when it seems opportunistically beneficial to them.. .. time will tell.. and yeah, there are likely some miners who are not exactly committed to the "core tenets of Bitcoin" even though they will talk the talk for a while and even walk the walk in order that might be able to wait for a better time to fuck around with their own dumbass sucking up to the PTB values that might be deeper within them...  Hey, but bitcoin was built for the ability to tolerate friends and foes from within and surely the incentives may well beat up upon some of the ones who play around too much.. .  We will see.. we will see. 

Nice to hear the statement though (even if it might not be their true feelings and thoughts).. so don't get me wrong about that.

“Marathon is committed to the core tenets of the Bitcoin community, including decentralization, inclusion, and no censorship,”

I wonder if their stock devaluation had anything to do with this considering that it has been dumping ever since its April pump. Maybe seeing $19.66 after reaching $56.56 was a wake up call that the investors don't like malicious miners.
