Looking at the merkle branches that mining pools send to miners as part of stratum jobs, it's clear that the BTCcom pool, Binance pool, Poolin, EMCD, Rawpool, and possibly Braiins* have exactly the same template and custom transaction prioritization as AntPool.

Stratum v1 jobs include (parts of) the coinbase transaction and the merkle branches a miner needs to compute the merkle root. If all branches are equal across pools, the block template is exactly the same.

This is a smaller merkle-tree with the stratum job branches highlighted.

Here, branch0 is the txid of the first transaction in the block after the coinbase.

In the AntPool/Binance/BTCcom/.. template, it's a manually prioritized transaction paying 9.03 sat/vbyte https://mempool.space/tx/c938e8027a7fba782a092695a53d37654021bf20df71ca91b4a6daa9198b0c73

Many of the other pools didn't prioritize a transaction and included the highest feerate transaction https://mempool.space/tx/96608dc747677d6dfbc3a2b37f8a0146abae132799b13c130066bd3716fdf91a paying 301 sat/vbyte. ViaBTC prioritized another transaction and has a vastly different template.

This indicates that F2Pool currently is not using the AntPool templates, even if they share the the same custody provider. We know from multiple occasions that F2Pool has been building their own templates (https://b10c.me/o11, https://b10c.me/o9, https://b10c.me/o8)

Note that SigmaPool and SecPool both seem to share the same template (distinct from AntPools template). Two names, but probably one pool.

Some overlap in the first branches of distinct pools is expected as these branches consist of few (usually high feerate) transactions. For example, Ocean's "default" and "core" templates overlap up to branch3. At least the first 15 tx (2⁴ - 1) in the template are equal.

* similar to EMCD in the picture, Braiins sometimes differs from AntPool in the later branches of the template. This could indicate they're only helping with AntPools transaction accelerator and directly syncing with AntPools mempool, causing occasional differences in templates.

I've heard speculation about this all being liked to an FPPS partnership with AntPool/Bitmain.

Bitmain insures against bad pool luck but you have to use Bitmains templates/transaction prioritization and pay the mining reward to the insurer for later distribution.

Essentially a pool of pools and a lot of mining centralization.

We should push for stratum v2 asap

Huge buying pressure (institutional inflow and halving) in a low liquidity environment = high volatility to the upside aka omega candle. Brace yourself. All the diminished returns crowd will be in disbelief.

I don't know where to post this but since nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 posted on how nostr was big relays dependant I tried using only small relays but I'm having a lot of issues :

- profile info missing

- missing notes (some of my follows notes were completely out of my feed)

- big latence to fetch data (notes appear suddenly in my feed or profile info updated after at least 5-10 seconds)

I don't know who could be interested in that feedback. Feel free to tag people in comments.

Here's an example on #bitcoin (I use amethyst)

And on nostr chats it is even worse :

I don't think so. I think people are not going to invest into eth through an etf and institutions have no use case for it as it's a security.

I think the eth etf narrative is already priced in and now whether the etfs are approved or not it will go down because it'll flop compared to bitcoin.

We will see.

So you would say a "decentralized" asset need approvals of centralized institutions to be legit?

I was asking why do you think ETH is a legit tech as a decentralized, secure, scalable and censorship resistant that can disrupt something?
