Knee X-ray time. Fingers crossed for spiderman powers afterwards.

There are 2 things to store in Bitcoin:

- the blockchain, 655 GB and always increasing

- the UTXO set, 11 GB and can vary

The blockchain has all the blocks, the UTXO set has all the UTXOs.

The UTXO set varies in size because transactions spend UTXOs and originate new UTXOs. If a transaction spends more UTXOs than it creates, it decreases the UTXO set and vice-versa.

The UTXO set is needed for transaction validation: when a new transaction appears, all inputs must be on the UTXO set, or else the transaction is invalid (because it is spending a non UTXO). When a transaction is confirmed on a block, its inputs are removed from the UTXO set and the new outputs are added to it.

When a UTXO is an OP_RETURN, we know for sure that it is unspendable, so we can remove it from the UTXO set or never add it in the first place.

There are some protocols that use the Bitcoin network to inscribe data. And they can do it almost everywhere: on the pubkey, on the witness, on the locking script or in an OP_RETURN.

The problem here is a protocol that decided to inscribe its data in the locking script, i.e. in the transaction output. They lock a very small amount of sats to a fake public key. Actually, the public key is the payload they want to inscribe. Of course it’s impossible to unlock this UTXO, so it will be unspent forever, i.e. it will never be removed from the UTXO set.

This protocol doesn’t use OP_RETURN because these are limited to 80 bytes, and they need something like 160 bytes for their payload (don’t know details)

So, since we cannot stop them, the idea is to allow them to do their inscription on an OP_RETURN. We don’t stop the spam, but at least they will not inflate the UTXO set.

Sold my car in 2020, bought #Bitcoin, and rolled into a $5K Corolla. That single trade didn’t just move wheels , it shifted my entire future.

And how are you looking?

Being an atheist in your teens and 20s is a sign of healthy skepticism.

Continuing to be an atheist in your 30s and beyond is a sign of spiritual immaturity.

For those of you who once were atheists, what was it that brought you back to theism?

Jup. Main advantage of the q is the bigger screen and qr code scanner. The seed vault is also very nice implemented in the q. You can easily add temporary seeds and passphases to the card and play with it. To be honest I use the q as my main device. If it fails or breaks I have always the mk4 as fallback.

Exactly. Indeed exactly the same seed. And in addition to that if you stored passphases on a SD card you can even use those on the new device. If you don't clone you have even use a new SD card again. It sounds complicated but it is what it is.

You don't have to setup your seed & passphase again

JUST IN: Warren Buffett suggests it might be wise “to own a lot of other currencies” besides the US Dollar.

Almost like a decentralized, non-sovereign currency could fix this. And yet, old pal still can’t grasp the value of #Bitcoin and rather stacks other fiat Shitcoins.
