What was the number of the block in which SegWit got activated? And first transaction?
It was definitely on August 24th 2017, but not sure about the block number. Many sources reference block 481,822; but others state 481,824.
Also, even if this was the first block to allow segwit transactions, what was the first very block that…

How does a SegWit node verify a block?
I know that non-SegWit node could verify a block without witness.
For SegWit node, is witness necessary to verify a block? Because I know witness are committed as wtxid merkle node in coinbase. What's the purpose of the wtxid merkle node?
If witenss…

If Btc2x doesn't have replay protection does that mean all transactions can be automatically replayed in btc2x?
I believe btc will have a lot higher economic activity at the time of the fork. If anyone sends funds in btc, what stops someone who don't like btc2x to just replay that same transaction on btc2x? This will shuffle around funds, to different…

At the moment SegWit2x forks, will mining be way easier?
Is there a need for people to run full nodes that are mining on CPUs when/if the SegWit2x fork occurs?
Will almost all of the mining power be switched over to SegWit2x?

Is the SegWit2X success due to concentration of mining power?
SegWit2X has been called a short-sighted & severely lacking proposal. There is nearly universal preference for its alternative among those listed on the segwit support overview (SegWit, BIP 141,148,149).
Yet SegWit2X has 90% mining support.
Is this…

To my understanding BTC and bitcoin core are the same, when mentioned against S2X/B2X. Is that the case? (Bitcoin Core is BTC in the post segwit2x world?)

Limit tx to SegWit1x or 2x chain
Given the lack of replay protection when the SegWit2x fork splits off a different chain is there a safe mechanism to broadcast a tx so that it will only be accepted by the 1x or 2x chain nodes?
If the answer is no would an option be to run both a…

Can there be a half segwit, half normal Bitcoin transaction?
I was wondering if it's feasible to compile a bitcoin transaction that is somewhere in between (segwit and non-segwit), maybe one of these scenarios. I'll call the non-segwit inputs, normal inputs just for the sake of simplicity.
Use one normal…

BIP91 Activation Period
I understand that BIP91 needs 269/336 signaled blocks.
My question is is it a rolling window of any 336 blocks or are there activation periods of 336 blocks that start and end at predetermined block numbers?

Who witnesses a Segregated Witness transaction and what incentive do they have to witness the extended block containing signatures?
This video claims Segregated Witness is insecure because no one has an incentive to process (witness) the extended signature block.
