CoinDesk Podcast Network - HARD PROBLEMS: 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.
This episode is sponsored by Nexo.io and Bitstamp.
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
If you'd like to join the live audience for our next Clubhouse recording where Jeffrey "Sneak" Paul joins Bram to dig into the hard and growing problems behind Ransomware, follow 'bramcohen' and 'adamblevine' on Clubhouse.

Unexpected Elements - Covid and clean air
We wouldn’t drink dirty water so why do we put up with polluted air? Researchers are calling for a major rethink on our attitude to air quality. Professor Lidia Morawska, from the Queensland University of Technology, says attention to air quality during the Covid pandemic has shown how levels of airborne disease can be reduced.
Sam Wilson from the UK Medical Research Council, University of Glasgow Centre for Virus Research has been investigating genetic mechanisms associated with susceptibility to Covid infection. His team has identified a molecule that detects SARS-COV-2 when it starts to replicate in our cells. However, not all humans have this protective mechanism, which may help explain why some people become very ill with Covid and others have little if any symptoms.
Many Europeans lack this protective molecule, whereas the vast majority of Africans have it. The difference can be seen in cell cultures. However, the lack of diversity in the cells used in experiments worldwide can be a serious problem when looking at genetic differences as Samara Linton reports.
Nuclear material buried beneath the doomed Chernobyl nuclear power plant is becoming more active Neil Hyatt Professor of Nuclear Materials Chemistry at Sheffield University says it’s a small increase but needs to be monitored.
And There are over 400,000 species of plant on earth, they’re on every continent including Antarctica. But humans only regularly eat about 200 species globally, with the vast majority of our nutrition coming from just three species. Many of the fruits, leaves and tubers that other plants grow are packed full of toxins that are poisonous to us, and would make us very ill if we ate them. But could we take out the poisons and create new, edible crops? That’s what CrowdScience listener Marija wants to know.
Crowdscience dives into this topic, and uncovers the that many crops are poisonous, and why so few plants are eaten globally. Host Anand Jagatia finds that even the modern scientific processes of crop breeding are very slow. But science can now engineer plants at the genetic level by adding, silencing or removing specific genes. This ‘genetic modification’ is hugely controversial but can be highly effective.
Anand finds a man who has spent decades making cotton seeds edible by removing the poisons they naturally produce in their seeds. This GM crop could help fend-off starvation. But sometimes introducing poisons can be as important as removing them, as we find in the genetically modified ‘BT eggplants’ in Bangladesh. The new gene makes the vegetable toxic to a major insect pest, so they are much easier to grow.
But GM crops are not the perfect solution. They have problems of gene escape, can increase the use of environmentally damaging herbicide, and can be open to monopolisation. In some countries, particularly in Europe, GM crops are hugely controversial. Anand finds out whether these concerns stand up to science and looks at the counterpoint in developing countries in Africa, South Asia and elsewhere, where local farmers like Patience Koku in Nigeria have little time for some of the concerns around GM, particularly as they see poor harvests, poverty and starvation as the more pressing problems.
