Inside Bram Cohen's Proof-of-Work Reinvention

Bitcoin's 'Nakamoto Consensus' changed the world. For the first time ever, strangers on the internet were empowered by a system that allowed them to individually and jointly track who owned which internet-native items... First money, then early stage (and often illegal) investments, followed by digital cats, multi-million dollar art, viral memes and soon enough, well, everything.

If there's one complaint (whether right or wrong) about Satoshi's breakthrough, it's the energy cost it comes at.

Whether you're talking about Bitcoin or the myriad other proof of work systems, 'Nakamoto Consensus' is a "competitive money burning process." Each time transactions are added to the permanent history it's a race to see who can prove their commitment to the network by finding the winning raffle ticket the fastest. Everyone races but only one wins and when each block is found, the process starts over. It's not a perfect system, but it works and it's the best one we've found... So far.

In this premiere episode of "Hard Problems", join BitTorrent inventor and Chia CEO Bram Cohen, CoinDesk's Adam B. Levine, community members JMHands and Michel Erb for a lively discussion of Bram's newly launched reinvention of distributed, proof of work consensus known as Proofs of Space and Time.

In it, we discuss

The challenges Bram believes his new system resolves
How 'Proofs of Space and Time' works compared to traditional 'Nakamoto Consensus'
The differences between Bitcoin mining and Chia farming
Why improving proof-of-work is the better choice than proof-of-stake or other consensus systems
Plus many questions from the live Clubhouse audience, with a special line of questioning from Tuur Demeester

Ransomware, Sandboxes and Security

American Hacker Jeffrey "Sneak" Paul joins Bram for a deep-dive into the hard problems behind the growing rash of ransomware attacks, what it means and what we can do about it.

This episode is sponsored by Nexo.io and Bitstamp.

On this episode we’re digging into, not a new problem, but an old problem that seems to be getting worse as a growing proportion of our lives are spent connected, to each other, to the internet and inadvertently to criminals who use technology to extort money, often in the form of cryptocurrencies. It’s called ransomware, and to help us understand and sort through today’s topic, Hard Problems host and Chia CEO Bram Cohen is joined by special guest Jeffrey Paul, better known as Sneak.

On May 7th, an employee of Colonial Pipeline Company found a ransom note on one of their computers. The pipeline provides nearly half of the fuel for the east coast and they were locked out. Days later, they’d admit to paying 4.4 million dollars in bitcoin to the group who did it. It’s the most recent high profile example, but it’s certainly not the only one. Going back through CoinDesk’s archive, I found nearly a hundred articles written over the years. We’ve seen hospital systems and industrial players extorted along with lots of normal people. And those are the ones that we hear about, it’s assumed that many victims of extortion simply pay the ransom and keep it to themselves.

This episode was recorded live over the audio only social network known as Clubhouse. If you'd like to join our live audience, our next recording session is Wednesday June 2nd, 2021 at Noon Pacific/3pm Eastern time where we'll be discussing modern music, it's eccentricities and how it's changing as technology plays an ever-larger role with grammy nominated composer and musical pioneer BT.
