many wallets offer sd card export, ledger offers mnemonic verification which also extracts the mnemonic, and of course while derivation and signing aint happening in the secure chip, there is no support for bitcoin crypto in cheap chips.

the main issue was that people didnt understand how hardware wallets work, so they took ledger claims the way they wanted them to be.

Your node forwords transactions and stops the spread of invalid transactions.
Its like a distribution service you get a transaction, check it and you send it to arround 6 (I guess) other nodes.

The biggest would be contracts themselves

Ooh, I see, so it's not for big files then.

I agree, what data do you need immutability for and justifies the price?

Bitcoin Dev

03 November 2022 22:49

Kind of, for important data

Bitcoin Dev

03 November 2022 22:39

If data is worth it, the price doesn't matter

Hello can you recommend good channels/groups for btc/eth devlopers?

Ok, time to study....

You could create múltiple OP_RETURN outputs maybe

Bitcoin Dev

Why isn't it a good idea? It depends on the data isn't it? All the transactions is also a data, blockchain is made for storing the data. Like proof of transaction, where transaction might be something different than bitcoin transaction

Well, now you don't need to know a miner to commit more than 80 bytes. Writing data to the blockchain is not a good idea indeed, commit might be.

Bitcoin Dev

I would prefer to have a same way to store it for different sizes of data, so I could also read it when I need, it can be encrypted data.

What exactly do you mean? Lightning is off-chain, but I could receive payments over lightning, yes.

once you input a pin, private key leaves the secure element, it always did, in all wallets

Hey guys, im new in BTC world, and im trying to find good RPC providers for mainnet BTC. Can someone suggest any?

Bitcoin Dev

Can someone explain how one extra node in the network secures the network (not miner, just a simple fullnode)?

Bitcoin Dev

03 November 2022 22:53

It's not, but I couldn't figure out why would someone need immutable files.

Bitcoin Dev

03 November 2022 22:50

At the risk of going off topic, how is ipfs immutable?

Bitcoin Dev

03 November 2022 22:49

There is already IPFS

Is the end goal making a something like a distributed cloud storage service?

Bitcoin Dev

03 November 2022 21:19

At a minimum, it will be an expensive idea

Bitcoin Dev

28 October 2022 14:26

I believe that another use case for bitcoin blockchain will only create additional value to bitcoin

Bitcoin Dev

28 October 2022 14:22

Not exactly, it’s a long history 😅

Bitcoin Dev

28 October 2022 14:20

What is the maximum size?

Bitcoin Dev

28 October 2022 14:19

No? Has the policy changed?

Bitcoin Dev

28 October 2022 14:16

As @sntgvrg says, you have OP_RETURN to introduce some text (80 bytes) or more if you know a miner and your TX is included. But, use Bitcoin blockchain to store data is not a good idea.

Bitcoin Dev

28 October 2022 14:10

Now it's perfectly possible, and you can even commit more than 80 bytes (OP_RETURN). However it doesn't seem like the right place for it, still the point with bitcoin, no one is going to refuse such a transaction.

Are you sure? Even the first block generated by Satoshi contained a message
