let's untangle what corporate treasurers do and why this matters...

the role of corp treasurer didn’t exist until the 1970s, when co's faced high inflation and financial uncertainty

1\ There is an alarming amount of misinformation (fueled by the media) on what exactly happened to Bitcoin yesterday, and whether funds were "double spent"

Here's everything you need to know 👇

2\ On the 18th, a user broadcast a transaction with very low fees.

When users underpay fees, their transactions gets stuck because miners have more profitable opportunities.

Users are left with 2 options:

a) wait until fee levels drop
b) tell miners they will increase fees

3\ The most popular way to (b) increase fees of an already-broadcast transaction is through a "Replace By Fee (RBF)" transaction.

Put simply, RBF is a copy-and-paste of the original transaction with higher fees and an explicit instruction to favor the new transaction instead.

4\ Nearly a day passed after our infamous user broadcast the original transaction and miners did not include it.

So the user decided to issue an RBF on the 19th with higher fees... but not high enough!

And the transaction was again stuck...

5\ A couple of hours later, the user decided to bump fees up again via a second RBF!

This time around the user paid enough fees.

Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial

institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps

transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came

from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure.

Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone. 1. Introduction
