This would be a zero conf lightning channel except it’s not even submitted to a mempool. There’s more trust involved but also more privacy.

If fees are high enough and your channel is small then your channel opening transaction would likely get pruned before being added to a block anyway. In that scenario you’ve leaked your intentions to the network and didn’t get the security of settlement.

Are there any #Nostr clients with embedded LLMs for filtering content?

Would be nice to have a client organize posts into channels where you can mute some, get notifications on others, etc

Is there any utility in creating lightning channels and all subsequent transactions without broadcasting to the network? Skip the mempool entirely?

For example in extremely high fee environments and with relatively trusted counterparties you could sign transactions and settle when fees come down. Effectively a credit system.

These spam attacks are basically just fund raisers for miners. Are there any incentives against this from the miners’ perspective? Are they inevitably going to promote these protocols? Is there anything we can do aside from education?

Yes there’s more risk but if you except some reasonable degree of trust in the parties (for example family members keeping tabs over many years) then you can save a lot on fees. Might work if you can expect that over the long term the economic relationship is balanced and there’s minimal expectation of dishonesty.

Miners are incentivized to drive their energy costs down as much as possible. The most viable ones will be net energy producers since their the marginal cost of energy to power their rigs is zero. Therefore you’ll see the mining industry merge with the global energy industry.

As bigger players come into the scene and the cost of going to space drops dramatically, then it’s a matter of time before governments start mining in space as a matter of national security. They’d deploy mining rigs in orbit as they’ll have limitless and mostly unobstructed sunlight at all times and there’s limited physical access to the hardware.

In the far distant future this could turn into an arms race to capture more solar energy as it’s far more abundant than any other source by far. Could bitcoin get us a Dyson Sphere? https://en.wikipedia.org/wiki/Dyson_sphere

An input to the market clearing price of a good or service is the transaction cost. Different layers of bitcoin have different transaction costs. As you ascend the layers from on chain, to lightning, to eCash the fees come down by orders of magnitude.

A cup of coffee can be priced at 3 sats if transaction costs are less than a sat. There’s no reason a car can’t cost 20,000 sats if purchased with eCash. Maybe having high fees on the base layer provides the right incentive and urgency for us to build viable ecosystems on Lightning and eCash protocols.

Mass adoption can’t happen unless people can transact with bitcoin as easily as cash. I’m inspired by the community here and know we can make that a reality.

How do you foresee this playing out? Do fees continue to rise up permanently above 2,000 sats/vbyte?

Seems like fees will be a function of the distribution of sats per UTXO. For example, if 1 million sat UTXOs become dust then the network strands a lot of adopters which seems unsustainable.

Ok I've built this for fun and it's incredible.

A Cashu gateway: it's a normal Cashu user who has a Lightning node (or another Lightning payment backend). Everyone can act like a gateway as long as the mint supports ecash HTLCs (NUT-15).

If you as a Cashu user know of such a gateway, your wallet can send your Lightning payment request to it instead of to the mint.

The gateway responds with an amount (it can take a fee). If you agree, you send it ecash, and it pays your Lightning invoice. The process is atomic.

What does that mean? Let's think a little ahead and imagine this was deployed on a significant scale.

Even if the mint is full KYC for peg-in and peg-outs, a user could still make Lightning payments anonymously with the help of other users.

(!!! this alone would be huge !!!)

This would also enable us to make on-chain-only mints which opens up a whole new way of building mints (reserves could be in a multisig for example).

Crazy part: Gateways can be lazy and use custodial Lightning backends. The user doesn't care as long as the invoice gets paid.

Yes. That means you could use your Strike or Blink or LNbits account to act as a Gateway for a Cashu mint you like.

There could be many of crazy people like you. Nobody would ever know. Neither the mint. nor your LN service provider would notice. They all just see invoices.

It gets weirder. Gateways could use *another Cashu mint* as an LN backend. I know sounds like an inception nut but bare with me.

A user of mint M1 can ask a gateway of mint M1 to pay an invoice. The gateway could pay the invoice via mint M2 and receive ecash from M1 in return.

I always thought "you could run a mint for a thousand users on a Strike or a Blink backend without them even noticing the smallest thing".

Now I think you could probably run a mint for 100k users without them noticing, if there are other gateways handling payments for everyone.

Note: this is still experimental. Only paying works right now over the gateway, not receiving (more complicated).

The bast part though is that it doesn't require any Cashu protocol changes and the mints don't have to give you permission to do this.

It's all pretty nuts.

At a time when runes are driving up fees to insane levels, I’m grateful for your work on e-cash. Thank you!

Google released a paper for a large scale distributed AI system called DiPaCo (https://arxiv.org/abs/2403.10616v1).

it seems desirable for a globe spanning powerful AI to be decentralized and openly accessible. to prevent DDoS prompts could be collateralized with bitcoin. the nodes running the computations would be compensated with the bitcoin payments. a virtuous cycle in some ways.

what would it take to marry a system like that with the lightning network?
