I made a quick screencast demoing OP_VAULT (BIP-345) with a little prototype wallet I've written in the last few days https://t.co/LFIL6Nappo

@rusty_twit @niftynei @callebtc Still using presigned transactions, but atomically committed to the chain: annex covenants

[Joost Jager @joostjgr]

@PatrickvdMeijde @NicolasDorier @mempool You mean that as a miner, your pool is not paying you a share of the collected out-of-band fees? Agreed that that is a more direct loss. I just meant to add to that that even if your FPPS pool takes no out-of-band payments, you might still be affected.

[Joost Jager @joostjgr]

.@mempool deployed total block fees auditing: https://t.co/V2PPAlu5zu

Check for yourself to see how good mining pools are at building the most profitable block.

Obviously this does not take into account potential out-of-band payments.

[Joost Jager @joostjgr]

@NicolasDorier @mempool Note that when one pool adopts out-of-band payments, it may decrease payouts for other pools if they utilize FPPS. This method calculates rewards based on collective miner fees over a set time period.

[Joost Jager @joostjgr]

The taproot annex uniquely enables the on-chain storage of signatures from child transactions without being hindered by circular references. This enhances the safety of implementing covenants through pre-signed transactions. Sample use case: time-locked vaults.

[Bitcoin Optech @bitcoinoptech]

Bitcoin Optech newsletter #255 is here:

- summarizes discussion about allowing relay of txs containing taproot annex data
- links to a silent payments draft BIP

@mempool Another example of specific work done for this: https://t.co/2jvYbgR5OD

In this instance, a hard-coded witness stack length was assumed.

[Joost Jager @joostjgr]

Taproot annexes, though non-standard, may appear on-chain anytime. Hence, it's wise to test taproot apps accordingly. @mempool recently fixed a related issue (https://t.co/5z7zogEqYd), which only impacted visuals. However, other apps may face harsher outcomes.

[Joost Jager @joostjgr]

@0xB10C Oh wow, that is awesome! Didn't know about your project. Are you considering the addition of pool-level comparisons such as a ranking based on block fee maximization?

[Joost Jager @joostjgr]

Working on an enhancement to mempool: compare expected vs actual tx fees in each mined block. An addition for transparency in bitcoin mining.

[Joost Jager @joostjgr]

Lightning protocol upgrade that also enables the identification and avoidance of slow routing nodes.

[LND PR Review Club @lndreviewclub]

PR #7139, by @joostjgr, adds the ability for nodes to generate and relay attributable errors, which are important to properly penalize nodes after a payment failure occurs.

@theinstagibbs This is great.

[Joost Jager @joostjgr]

@RaymondDurk @BKronyte @StratumV2 Agreed, twitter is far from ideal to reach miners. Yet, in a scenario where let's say 144 miners produce one block daily according to their own templates, the odds of one picking up a high-reward tx are probably higher than with 5 pools controlling 80% of block production.

[Joost Jager @joostjgr]

While I understand the technical challenges in mining this non-standard yet harmless and consensus-valid Bitcoin transaction, I can't help but wonder: if Bitcoin were truly decentralized, wouldn't someone have stepped up for the 50x premium that it offers?

[Joost Jager @joostjgr]

Increasing the reward to 1000 sat/b. Any miner care to pick up this transaction? @FoundryServices @f2pool @AntPoolofficial @ViaBTC @ckpooldev @binance #btctxannounce

https://t.co/VjVu7kE39e

[Joost Jager @joostjgr]

@sr_gi Indeed. I could have done a zero fee parent with fee paying child instead of a non-std tx, but that would present different technical hurdles given that submitpackage isn't available yet in core.

[Joost Jager @joostjgr]

@BKronyte Absolutely! I think @StratumV2 with Job Negotiation would be immensely helpful here. Can't let only a handful of people in the world determine which txes are allowed to enter the chain.

"Hence, instead of forcing clients to go below a static target like in Bitcoin to be successful, we ask clients to "bid" using their PoW effort. Effectively, a client gets higher priority the higher effort they put into their proof-of-work."

[Joost Jager @joostjgr]

@Tsartoshi @MonadicHodl @jamesob Maybe this is just a fraction of the bots and spam that would be present if they didn't make an attempt at all to combat it?

Testing twitter-based bitcoin tx relay. The following unconfirmed tx pays 100 sat/b. Are miners pulling from twitter yet?

[Joost Jager @joostjgr]

@EdwardHodl @FoundryServices @f2pool @AntPoolofficial @ViaBTC @ckpooldev @binance That's why you need to be a miner to pick it up
