is there already a tool to monitor BIP 66 acceptance status? (the number of bloks that say they are v3.0)

as per https://bitcoin.org/en/release/v0.10.0

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Following.

Is there a page which lists what % of the network has upgraded to 0.10.0?

Thats fine for monitoring nodes, but for the soft fork what matters is hash power. https://blockchain.info/pools shows that if the right 6 pools upgrade, then that will trigger the soft fork.

Not exactly "a tool to monitor BIP 66 acceptance status", but closest thing that I have seen. bitcoin.sipa.be/ver-ever.png

want is interesting to monitor is how many of the latest 1001 blocks have v3 mark.

here's the voting  scheme:
Quote
when 751 out of a sequence of 1001 blocks have version number 3 or higher, the new consensus rule becomes active for those blocks. When 951 out of a sequence of 1001 blocks have version number 3 or higher, it becomes mandatory for all blocks

Current status: 11 out of 1000 blocks with version 3.

My script is at https://github.com/domob1812/namecore/blob/master/contrib/bip34-monitor/scanBip34.py.  (Is this interesting as a pull request to Bitcoin, or not?)

EDIT: Note that this script is initially for Namecoin.  So you have to change also the RPC port to use it.

Looks like there was a spike in the last few days.  If that is maintained, it means the vote is around 57% - 43%.  I guess a pool must have upgraded.  The 1 year graph shows a slope due to initial release then level then a step and level again and now another step.

There was a version of 0.9 released which can handle version 3 blocks.

This allows nodes running older versions of the software to vote/accept version 3 blocks.

http://sourceforge.net/p/bitcoin/mailman/message/34124466/

https://github.com/bitcoin/bitcoin/blob/0.9/doc/release-notes.md

Once 75% of the network starts enforcing the rules, legacy nodes could end up accepting invalid version 3 blocks.  That is an expensive DOS attack though, since it requires spending POW on invalid blocks.

And the attack like this would not be very effective because 75% of the network is mining a more restrictive chain.

And the attack like this would not be very effective because 75% of the network is mining a more restrictive chain.

I think the more common theorized attack vector with this situation is double spending.
