Bitcoin Core Nodes - Is RBF a Good Option?

The way they prevent that scenario from happening is by not signaling RBF. So data transactions do not opt into RBF, which means that by default, if an attacker tries to do this and they're only connected to regular Bitcoin core nodes, those transactions won't propagate. But that is still quite risky because again, a sufficiently motivated attacker would find one of Peter Todd's nodes and just connect to those or directly connect to a miner If they can find it and start stealing it. And I think they know that it's not safe and they want to improve it. It is we're hoping that they'd have another year on the roadmap before they would have to do this.
