The attacker gained control of the "qix" NPM account and published malicious patch versions for some of the most fundamental utilities in JavaScript, [] core building blocks buried deep in the dependency trees of countless projects.

Speaking of ordinals, counterparty sorta got messed up over last year, I think thx to them. I hope they don't remove opt return limit.... Already I recall (Jeff garzick I think, edit too many years ago can't remember who) making that shitcoin which only used up btc block space, stupid fking idea. Anyway, there are alot of ppl that want to spam the chain and will do so easiest way possible. Concerning.

good point, so jpegs wont even move to op_returns until discount is changed

Not sure if Elisabeth Warren and her Operation Chokepoint goons will see it that way. And good luck explaining that nuance to no-coiners when the headlines start circulating. They don’t even know what a block is. They’ll think it’s all right ‘on the coin’. When it comes to jpeg viewers, sure you have a point, the burden of filtering will fall on them, partially... But the opportunity for anyone trying to attack bitcoin and spread a false/malevolent narrative is on easy-mode, and damage is permanent.

You can also etch CP image (in binary) into the road, and then claim satelite maps distribute CP. Its just silly, but if you also provide/host/promote parsers you might be jailed.

Can someone explain how when illegal media (you know what kind i mean) gets stored on chain when OP_RETURN limit is removed the following wont happen:

1 - governments will force institutions and large miners like antpool and foundry to abandon the tainted chain and propose a clean hard fork
2 - the tainted (original) chain will get blasted by media and regulators until no one wants to get associated by it
3 - the online safety act will be used as a weapon to attack BTC node runners and possibly block explorer infrastructure

Please explain to me why this risk is worth it and the core30 update is justified.

Were block hash checkpoints removed from Bitcoin Core implementation?

Hello sers! Anyone here looking for developers or designers by any chance?

One solution is HD wallets (BIP32/44). It can generate many addresses from a single seed, & monitor them all by watching that xpub or address descriptor, using a bitcoin node or electrum server.

I want to make a tg bot so that the user enters his name and bitcoin wallet, and then receives the address to which the bitcoins need to be transferred, and as soon as he has transferred them, I should receive a notification about this.

Onchain jpegs are done via inscriptions, where they benefit from the witness discount. They have nothing to do with the op_return length filter.

Furthermore, there is essentially no way to stop jpegs, you'd have to make the chain permissioned.

Other than that, CP jpegs can (and probably are) already writen in the other parts of transactions, changing the OP_RETURN wont enable anything new in that regard, if anything, it will allow node runners to more easily prune CP out of their nodes (this assumes the jpeg etchers will be so nice to start using OP_RETURN again).

Governments don't care if there is CP in logs, they care about software that displays it- so deployed web parsers, maybe even executables offered if they are promoted for CP use. So if you are making software to read it, make sure you enable filters and whatnot.

The simple answers is don't deploy jpeg viewers if you are not willing to censor what gets shown.

Everything else reads like a fantasy.

DNS seeds (like seed.bitcoin.sipa.be) return a hardcoded or dynamically curated list of Bitcoin nodes. They don’t filter out the querying IP address

- Upon attempting a connection, if the destination IP matches the node’s known external IP, it avoids connecting.

- If a connection is established and the node detects that the remote peer is actually itself (e.g., via nonce check in version message), it drops the connection.

Relevant part in Bitcoin Core (net.cpp, CConnman::ConnectNode):

if (addr == self) {
LogPrint(..., "Skipping self-connection attempt to %s\n", addr.ToString());
return false;
}


And in ProcessVersionMessage:

if (remote_nonce == local_nonce) {
// Detected self-connection
pnode->fDisconnect = true;
}


A new node may not immediately know its public IP, but it uses:

UPnP or NAT-PMP to discover public IP and set port forwarding.

Echo: When it connects to other nodes, they may send addr messages containing the node’s IP as seen from their side.

Outbound socket binding: The local IP used to make outbound connections can be used as a guess.

Manual setting: via -externalip in config or CLI.

This isn't perfect, so Bitcoin Core also maintains a "local address score" system to rank and confirm its best guess.
