One of the most limited blockchain resources is blockspace. From Bitcoin’s Blocksize Wars to Ethereum’s scaling roadmap, a common denominator seems to have emerged in the form of rollups. Advancements in zero knowledge proofs have enabled trustless bridges, which are a cornerstone to onboarding liquidity to any blockchain. Furthermore, Celestia’s modular approach to blockchain architecture and their recent commitment to gigabyte blocks of data availability marked the beginning of commoditization for rollups. Abundance is the first rollup-as-a-service platform that is able to scale to 1 gigagas/second throughput, finally bringing off-chain applications, on-chain.

Topics discussed in this episode:
- Gelato’s pivot to rollup-as-a-service platform
- Sovereign rollups
- Enshrined bridges and settlement proofs
- Abundance and 1 Gigagas/second rollups
- Modularity
- Security assumptions
- Sequencer (de)centralisation
- Social consensus
- Celestia’s DA layer bandwidth
- Ethereum native rollups
- Decentralisation and censorship-resistance

As the cost of computing continues to plummet, the number of connected devices is increasing dramatically. In the future powerful computing capacity will be in billions of devices ranging from the lightbulb to the car door to new wearables. This new internet of things (IoT) will dramatically change our lives. 

Paul Brody, a Technology Strategist and the former VP of Mobile and IoT at IBM, joined us for a discussion of where the IoT is going. We discussed their white paper on why a decentralized, blockchain-based internet of things could solve the problems of the current IoT in terms of privacy, scalability, and business models.

Topics covered included:
        - What the Internet of Things and its core value proposition is
        - Why the current IoT business models are broken
        - How a decentralized IoT infrastructure would be more secure, scalable and economically feasible
        - What role the blockchain could play in a decentralized IoT
        - The three components of IBM’s ADEPT proof-of-concept

Bitcoin's approach to solving the double spending problem is to make a collusion and attack on the network prohibitively expensive. One of the main factors that will determine Bitcoin's chance of survival in the long-term is whether the behavior that maximizes the profits of miners contributes to or sabotages the health of the network.

The game theory that determines this is complex and our understanding of it still incomplete. But research is increasing and two people who have been at the forefront of this work are Emin Gün Sirer, a professor in computer science at Cornell University, and Ittay Eyal, a post-doc at the same department.

They joined us for a fascinating discussion of their work on 'selfish mining', the incentive structure that underlies Bitcoin and their recent positive conclusions from the Miner's Dilemma. 

Topics covered included:
        - Emin Gün Sirer's early interest in cryptocurrencies and work on a cryptocurrency to incentivize bittorrent users in 2004
        - What selfish mining is and how miners could profit from withholding blocks
        - How an attacker would execute a selfish mining attack
        - Why the miner's dilemma implies that the equilibrium might be small mining pools
        - Why the lack of security of clients and servers is holding back adoption

Whether the block size should be increased to 20MB has created more controversy than any other question in Bitcoin's recent history. For some, it is an urgent and necessary step in Bitcoin's evolution. Their view is that leaving the block size at 1MB would be irresponsible inaction with potentially catastrophic consequences. Others see increasing the block size as unnecessary and a dangerous first step down a slippery slope towards a more centralized Bitcoin.

We were joined by Mike Hearn, along with Gavin Andresen the most outspoken supporter of a block size increase. He is also the creator of Bitcoin XT, a modified fork of Bitcoin Core, that may become the vehicle for the push for bigger blocks if no agreement is reached regarding Bitcoin Core. Don't miss this crucial conversation!

Topics included:
- What would happen if blocks started being consistently full
- Whether bigger blocks create a centralization risk
- Why Bitcoin core development has become pervaded with toxic division
- What Bitcoin XT is and how it differs from Bitcoin Core
- The roadmap ahead and how a transition to BitcoinXT would occur
- Update on Lighthouse

Attracting over 70 of the world's biggest financial institutions to its consortium in just over a year, R3 has accomplished a formidable task. Aiming to rethink the fabric of the financial system, they first conducted experiments testing blockchain platforms for their member and last year began developing their own distributed ledger platform: Corda. 

The effort to build Corda was lead by R3 CTO Richard Brown and the former Bitcoin developer and R3 lead architect Mike Hearn. In a wide-ranging discussion, we covered the vision of the project and why it represents a radical departure from existing blockchain platforms.

Topics covered included:

- The origin story of R3
- Why existing blockchain designs didn't meet their needs
- How the R3 team lead a design effort to develop a new platform from scratch
- The business problem Corda is aiming to solve
- The components of Corda's architecture

As is the case with most luxury goods, the diamond industry is faced with the issues of theft, fraud, and counterfeiting. Illegal activity is present at every level of the supply chain, which collectively costs the industry and its insurers hundreds of millions of dollars each year. In recent years, international treaties and regulation have been put in place in an attempt to combat illegal activity, but criminals are most often a step ahead.

Leanne Kemp, CEO of Everledger, joins us to explain how her company is using advanced geological techniques, and blockchains, to bring more traceability to the diamond industry. Everledger, whose clients include many of the largest insurance companies, builds software which allows for a diamond's unique characteristics to be hashed and notarized in the blockchain. Hence, a stone's provenance, and the trail of ownership can be traced, therefore limiting the opportunities for fraud and making it difficult for stolen diamonds to re-enter the market. 

Topic's covered include:

- Leanne's background as a technologist
- A broad overview of the diamond industry
- A look at the diamond supply chain
- What roles banks and insurance companies play in the supply chain
- How diamonds are uniquely fingerprinted
- The Kimberly process and other regulations
- Everledger's technology stack and business model
- Other sectors which can also benefit from increased traceability

The healthcare industry is paradoxical. On the one hand, treatment technologies represent some of the most advanced science known to humankind, while some administrative tasks are still performed using paper and fax machine. Studies have shown that the administrative costs of healthcare can represent up to one-third of the total cost of care. Also, as diagnosis, treatment, and care, becomes increasingly data-driven and patient-specific, the industry needs to adopt more secure and robust technologies to manage patient data and communications between the patient and the different participants in the healthcare supply chain.

We are joined by John Bass and Corey Todaro, who are respectively CEO and CPO of Hashed Health, an innovation firm focused on accelerating the meaningful development of blockchain and distributed ledger technologies for the industry. Hashed Health works to build solutions which leverage blockchain to solve some of the most important challenges facing this sector.

Topics discussed in this episode:
- John and Corey's respective backgrounds in the building technology for the healthcare sector
- Nashville as a hub for the US healthcare industry
- What is Hashed Health and what problems the company is trying to solve
- The particular issues facing the US and global healthcare sectors
- How healthcare in the US differs from that of European countries
- The different entities of Hashed Health: Hashed Collective, Hashed Labs, and Hashed Enterprise
