Concerns About Bitcoin v30 and OP_RETURN Spam

So there's a lot of chatter about Bitcoin version 30 that's coming up. People are kinda worried about this OP_RETURN size limit lift leading to spammy NFTs and even worse stuff clogging up the blockchain.

Honestly, most of these worries are overblown. There's only one real outcome that might happen, but it's more tied to the market's vibe rather than any actual tech issue.

What even is OP_RETURN? It's that thing that lets you store data in transactions, isn't it? I heard Satoshi put some message in the first block, so it’s been around for a while.

Wouldn't it be slick to stash a PGP-encrypted seed phrase in OP_RETURN? Right now, that’d take tons of transactions which is costly and a hassle. If they raise the limit, could save a ton of trouble.

You can already do that though with tools like Stampchain and Ordinals. They make it easy to store your stuff without all that reassembling nonsense. Miners are cool with those 'non-standard' transactions too.

But seriously, who wants to put their seed phrase out there for everyone to see? That's just asking for trouble.

This thread is solid but needs better visuals. The formatting is a bit off too, but that's just me being picky. Just don’t go recommending risky stuff like that; someone might forget and get wrecked by a compromised key.

The OP_RETURN change is really about boosting efficiency. I think it's meant to steer users away from risky methods, not push spam.

I see your point, but it feels like the way people use data on the blockchain is about to change a lot. The NFT market is pretty limited, and these changes might not create more demand.

If you’re worried about PGP keys getting compromised, just don’t expose them. Responsible users can still use PGP, just gotta watch out.

Yeah, but remember back in the day when people thought PGP keys were foolproof? Fast forward, and those keys turned out to be less secure than they thought.

Great analogy! They're trying to make OP_RETURN more appealing compared to other options. Maybe it’ll keep the serious users from using the bad stuff?

I ran tests on the new Bitcoin Core version, and the idea that raising OP_RETURN won't lead to spam is inaccurate. I pushed a malware file through and it flagged the blockchain. Serious concerns here.

True, malicious users probably won’t choose OP_RETURN if other methods are available. They’ll usually go for what gives them the biggest bang for their buck.

Exactly. It's not like a flood of new spammers will suddenly jump in just because of this update. They’ll switch if it suits them, but I doubt it’ll be that simple.

Just to clarify, the issue isn't just about data on-chain. It's about what happens with that data. If you embed something sketchy, it could mess with node operations.

You mentioned spammers might pick the cheapest route. Well, they usually go for what maximizes damage, not just cost. Raising OP_RETURN might just give more incentive for spam.

I really don’t get why you’re assuming the floodgates will open. Like, spammers will still have to deal with costs and risks. It's not gonna be a free-for-all.

Just a heads-up, some people still misunderstand how block explorers work. Not all wallets can see the same data. This isn't a new issue, and we had ways to exploit before the changes.

Man, OP is just plain wrong. The idea that OP_RETURN is less harmful ignores the past. These tweaks don’t mean spammers will stop finding ways to get their stuff through.
