How to Apply RBF (Replace By Fee) to Save the Bitcoin

Due to Bitcoin's HUGE tx backlog & "Replace By Fee", it is now very easy for anyone to cancel and 'claw back' their transaction for hours or days! 2 demos with proof. This is not possible with Bitcoin Cash because Bitcoin Cash does not have RBF. Bitcoin Core's security model is flawed.

See examples below for how to execute this.

Demo 2:
https://www.reddit.com/btc/comments/7iam92/just_successfully_double_spent_a_btc_transaction/
 
 
More about this:
It is the first time attackers have such a large "attack timeframe" due to the mempool being so huge. Now attackers have several hours up to days to perform their attack.
In addition, Core has increased the the max time in mempool from 2-3 days to 2 weeks. And we all know why: because if it were still 3 days, too high of a proportion of transactions would constantly be dropped due to the huge backlog.
Lastly, this is made possible due to Core's enabling of "Replace by Fee".
When the BTC mempool was emptying every single block, or thereabout, the attacker had better act quickly. Now a lazy attacker has from several hours to several days to perform the attack.
And it's not like it's complicated: this particular attack was performed by a regular user (a total noob).
So much for Bitcoin Core security. It is worth noting that Bitcoin Cash does not have this problem as it does not have RBF.

Excellent explanation of why RBF (replace by fee) is a bad thing — and why it was one of the many “features” which broke Bitcoin BTC. (Bitcoin Cash has never had RBF.)

Using RBF to replace your unconfirmed tx in the mempool

What is replace by fee (RBF)?

Bitcoin Core released a feature called 'opt in RBF' which allows you to create a transaction that can be replaced in the mempool with a newer transaction with a higher fee. If you want to read more about the details of it, you can read this FAQ.
As the 'opt in' part states, you need to take specific action to allow your transaction to be replaced in the mempool. One input on your transaction must have a sequence number less than 0xffffffff - 1. For more information read BIP 125.

How do I use this?

Bitcoin Core provides a flag -walletrbf to have transactions created by default w/ RBF enabled. This allows you to create subsequent RBF transactions to replace your unconfirmed tx in the mempool eloquently. You can use peter todds RBF tool to build the transaction, not sure if Bitcoin Core provides that functionality by default.

Depends on the context. It's secure when it comes to confirmations, and that's my mistake, but 0-confirmation transactions are not safe anymore because of RBF implementation.
This flaw has been exposed multiple times using BTC wallets. Someone can cancel a transaction by setting a fee rate, making a 0-conf transaction, and then changing the fee rate right after.

Bitcoin is incompatible with RBF

RBF goes against so many principals of Bitcoin that it blows my mind it even happened.
Part of me thinks SegShit was just a distraction so Peter Toddler could sneak in RBF.

Variants Of Bitcoin RBF Full RBF: So-called “full RBF” unconditionally allows a transaction to replace older ones so long as it pays a sufficient fee. Opt-in RBF: The “opt-in” variant only allows the replacement when the transactions being replaced have explicitly signaled they allow replacement. RBF does not allow for the receiver to fight it out with the sender for control of the money. A merchant cannot reissue a transaction that has been made to it under RBF. What you are thinking of is a combination of RBF and CPFP (Child Pays For Parent). As far as I know, CPFP will not be implemented in the next Bitcoin Core. RBF is a way for someone who is experiencing a stuck Bitcoin transaction to get it ‘un-stuck’. How does a transaction get stuck? Usually a transaction gets stuck because the sender did not pay a high enough fee. Bitcoin Knots. Bitcoin Knots allows the user to easily configure its replacement policy. Opt-in RBF, full RBF, and strict first-seen policies are supported. Peter Todd's full-RBF patchset. Peter Todd has historically maintained patchsets against Bitcoin Core 0.8.x and later that implement full-RBF for all transactions in the mempool. Bitcoin wallets with the RBF feature. Double spending with RBF. Suppose a malicious user has ordered an item from an online shop, and he paid using bitcoin (RBF enabled) with a low transaction fee. He informs the shop keeper that the transaction will be approved soon. So, the shopkeeper sents the item hoping that the transaction will be mined.
