For episode 21 we had Asher Tan on CEO of CoinJar, a very successful Australian Bitcoin startup that offers similar services to Coinbase. We talked about the plans with CoinJar, what we think of Circle’s new product and the recent price increase.

Levin Keller, who is a board member of the German Bitcoin foundation, joined us to talk about a recent statement by the German Finance ministry on Bitcoin. He has been warning about a possible sales tax on Bitcoin for months and that seems to be happening now. We talked through what the recent announcement means for businesses and where we’re likely to go in the future.

The College Cryptocurrency Network is a non-profit organization which aims to provide students, academics, and faculty with the guidance and resources required to start independent Bitcoin clubs on college campuses and in schools. Since being founded in early 2014, the CCN has grown to well over 100 chapters, on every continent, from middle schools to PhD programs. 

Director of Student Outreach, Jacob Sears, and Creative Director, Dean Masley, join us to talk about the CCN's work and their personal experiences with starting clubs in their respective universities. We also talked about how the concept of Bitcoin is received by students and the potential for blockchain innovation and adoption on university campuses.

EB47 – College Crypto: Jacob Sears and Dean Masley talk about Bitcoin Education

Prolonged range bound markets are a hallmark of bearmarkets and they usually end up chopping inexperienced or over leveraged traders. Customised structured products offer a solution for market participants that want to limit their downside, but also the upside, by introducing knock-outs at certain levels or triggers. Such custom options, usually with lower probabilistic chances of occurring, naturally come at a discount. This allows traders to hedge their risk, while also betting on certain outcomes or market scenarios.

We were joined by Zhiming Yang, co-founder of Orbit Markets, to discuss crypto derivatives and how TradFi expertise applies to customising structured products for crypto markets.

Topics discussed in this episode:
- Zhiming’s background in investment banking
- FX derivative products
- Exotic options
- Crypto structured products
- Custom solutions for crypto miners
- Hedging Uniswap V3 impermanent loss
- Options based on prediction markets
- Managing counterparty risk
- Protocolising structured products
- Differences between TradFi and DeFi

At just 20-years young, Vitalik Buterin is one of the most brilliant minds in the cryptocurrency space. Previously, a co-founder of Bitcoin Magazine, he has conceptualized Ethereum, the most radical and ambitious cryptocurrency project since Bitcoin. After raising $18m in a crowdsale, a team of over 30 are working on launching the project by March 2015. In his work on designing a system for the future, he has been grappling with many of the hardest problems in the cryptocurrency space over the past year.

In a fascinating discussion, we covered:
- How Ethereum has evolved since the white paper
- The problems of Proof-of-Work
- Why Proof-of-Stake is the future of consensus protocols
- Why his main focus has been on consensus issues and scalability
- Why Bitcoin will never be stable enough to price things in
- The flawed ideology of ‘Bitcoin maximalism’ that prevents people from considering Proof-of-Work alternatives

That the bitcoin price is highly volatile is no secret. Opinions differ on whether that is just an inevitable roadblock to be passed on the way to world domination or whether it represents a fundamental flaw that will prevent Bitcoin from ever achieving widespread use as a medium-of-exchange. Seasoned hedge fund trader and monetary systems expert Robert Sams, is of the latter view and has been among the leaders in conceptualizing what a stable cryptocurrency should look like. It's an issue that is at the very heart of how the cryptocurrency ecosystem will develop.

Topics covered included:
- Why volatility is an obstacle to cryptocurrency adoption
- The two big problems of creating a stable cryptocurrency
- His proposal for a stable cryptocurrency: Seignorage Shares
- How finance professionals perceive Bitcoin

Eris Industries spawned when three people got together to come up with a solution to Olivier Janssens' £100K bounty to replace the Bitcoin Foundation with software. Their proposal, initially called Project Douglas and built on top of Ethereum, was designed to replicate the functions of a trade association on a blockchain. Today, Eris has evolved into a Distributed Application Software Stack, with which developers can rapidly deploy distributed applications that are flexible, legally compliant and secure. Interestingly, Eris allows organisations and companies to adopt blockchain technology without being fully decentralised.

We're joined by one of the Founders and COO of Eris Industries, Preston Byrne, who explains how Eris works and talks about some of the practical use cases which may arise. Siân Jones is also here to weigh in on some of the innovative aspects of this exciting open-source project.

Backbone to the financial system? Powering decentralized technology? The first true world currency? There is probably who hasn’t dreamt of a world ten years from now when Bitcoin would be all those things. The promise of cryptocurrencies are enormous, but will Bitcoin really emerge as the winner? And how can we reconcile this grand vision for Bitcoin with an ecosystem where projects launch new coins and blockchains every day?

The one project that rekindles those Bitcoin dreams and paints a potential path to Bitcoin’s ultimate success are sidechains. Developed by Adam Back, Greg Maxwell and several other Bitcoin core developers, sidechains aims to allow the permissionless, rapid innovation of alt chains, but using the established monetary base and network of Bitcoin.

It’s a complex project, but with Blockstream founders and sidechains visionaries Adam Back and Greg Maxwell we couldn’t have had better companions on our journey into understanding the coming Bitcoin-Sidechains-Macrocosm. Topics included:

- The motivation behind sidechains
- The concept of digital scarcity
- Concerns about the security of sidechains
- Different stages of sidechains from federated pegs to merged mining to block extension

Is Bitcoin secure from attacks that could destroy the currency? To a large part, this is determined by how expensive it is to carry out an attack and by the potential profits the attacker could generate. Ideally, an attack is so expensive to carry out that no profit-driven attacker would engage in it.

But in this episode, Brian argues that the cost of attacking Bitcoin will likely decrease in the future and the ability to short Bitcoin and thus benefit from an attack will increase dramatically. We take an in-depth look at the anatomy of such an attack including:

- How an attacker would need to go about shorting bitcoin
- How the kamikaze mining pool could be used to bribe miners to join the attacker
- Why all profit-driven miners will have an incentive to join the attack, whether or not they believe it will succeed
- Why the block halving in 2016 could be an exceptionally dangerous time for Bitcoin, since an attack would be cheap to execute and likely to succeed
- How a gradual decrease of the block reward, instead of the 4-year halving rhythm would reduce risk

EB68 – Kamikaze Attack, Block Halving And The Perils Of Proof-Of-Work

Ethereum’s transition from proof-of-work to proof-of-stake created a unique set of conditions (i.e. lack of protocol-level delegation, 32 ETH requirement, long exit queues, etc.) that led to Lido’s liquid staking model to gain huge traction, significantly eclipsing other LSD providers on native PoS chains. stETH added on-demand liquidity, bypassing withdrawal windows, while also increasing DeFi utilization and increasing yields. Moreover, by allowing users to stake any amount of ETH in pools, it removed the requirement for 32 ETH increments, ultimately improving decentralisation through long tail distribution of individual stakers. Lido V3 introduces modular stVaults which enable staking customization. This allows professional actors, such as institutional stakers, to have granular control over validators, MEV and other parameters, diversifying their investment strategies.

Topics discussed in this episode:
- Hasu’s background
- Discovering Lido
- Liquid staking and the early days of Lido
- Why liquid staking gained traction on Ethereum
- The evolution of Lido
- Initial decentralisation concerns and the importance of dual governance
- Restaking
- Lido V3 and vaults
- Institutional staking & ETFs
- Ethereum’s ‘crisis’ and its values

#592 Hasu: Lido – Ushering in Institutional Staking Through stVaults

Namechain is an L2 developed by ENS Labs, to enhance the scalability and efficiency of managing decentralized identities on Ethereum. It is designed to work in tandem with ENS V2, which introduced a hierarchical registry system for more efficient subdomain management and custom resolvers. A key vision for Namechain is to unify multi-chain user identities, creating a ""digital identity chain"" that simplifies how users interact with the broader blockchain ecosystem. This is achieved through features like L2-to-L2 bridging, which allows users to initiate ENS-related activities from various Ethereum Layer 2 networks, not just Namechain itself.

Topics discussed in this episode:
- High level overview of ENS
- Crosschain functionality through CCIP Read
- Domain squatting
- Onboarding ENS users via Paypal and Venmo
- Google & GoDaddy integrations
- ENS V2 upgrade & Namechain
- Transferring tokens from Namechain to L1
- Sequencer security assumptions
- Scalability
- New features & use cases
- ENS roadmap & metrics

#596 Adeniyi Abiodun: Mysten Labs – How Sui Leverages Move to Build the Composable Web3nternet

Taiko is a decentralized, Ethereum-equivalent (type I) rollup scaling solution which uses ZK technology. Taiko's goal is to scale Ethereum efficiently while maintaining security and decentralization. Being a type I zkEVM, Taiko retains full Ethereum equivalence, which creates a seamless DevEx, although this comes at the expense of UX as slower proof generation is the main trade-off. Moreover, in order to stay true to its decentralised ethos, Taiko operates as a based rollup, meaning that transaction sequencing is performed by L1 validators.

Topics discussed in this episode:
- Joaquin’s background
- Loopring and Taiko’s beginnings
- The 4 types of zkEVMs
- Taiko's zk circuits vs. Polygon’s
- Based sequencing
- Data availability and blob commitment
- Ethereum’s role in the future

#597 Joaquin Mendes: Taiko – Scaling Ethereum in a Decentralised Manner

As society evolves, so do its values and principles, but is that desirable for technology that seeks to build the most reliable, trustless and censorship resistant global settlement layer? Ever since the rise in popularity of Solana with its inflow of retail capital in a memecoin gold rush, Ethereum became even more criticized for sticking true to its core values despite the completely divergent demands of market participants. Moreover, the rollup centric scaling roadmap seemed to further silo attention and cause liquidity fragmentation, driving away value from Ethereum mainnet. As institutional demand is expected to grow with the introduction of staking ETFs, a new executive leadership took charge of Ethereum foundation to help steer the protocol’s narrative at the intersection between community demands and Ethereum’s ethos.

Topics discussed in this episode:
- Hsiao-Wei’s & Tomasz’ backgrounds
- How they became co-executive directors of Ethereum Foundation
- Ethereum Foundation’s role moving forward
- Decision making in Ethereum Foundation
- Shaping Ethereum’s narrative
- The layer 2 landscape

#600 Emin Gün Sirer: Avalanche – The Multi-Chain Avalanche

Blockchain architecture is constantly being forced to adapt to new technologies, as well as to meet new demands from users and builders. While the idea of apps building their own chains was first explored by Cosmos, it lacked the support and tooling to see it succeed. Later on, rollups also took the centerstage of Ethereum’s scaling roadmap, but due to their general purpose design, it led to a cannibalistic ecosystem. Initia learned from these 2 models and combined the best of both worlds: it built a full-stack framework for a seamless DevEx from the get-go and, more importantly, it designed its tokenomics in order to ensure maximum incentive alignment for its appchains. While the former decision removed the need for each separate chain to reinvent the wheel and risk ending up ‘a jack of all trades, master of none’, the latter ensured that appchains would not extract value away from the L1.

Topics discussed in this episode:
- Ezaan’s background
- From building on Terra to Initia
- How Initia is rewriting the appchain thesis
- Initia’s enshrined liquidity & vested interest program (VIP)

#599 Anil Lulla, Ezaan Mangalji & Jose Maria Macedo: Initia – Incentively Aligned Appchains

After a decade of existence, Ethereum has gone a long way from its initial whitepaper, yet many efforts in scaling and finding product-market-fit have been severely criticized for falling short of their promise. However, despite numerous other ‘Ethereum killers’ being launched over the years, none has managed to attract so many developers and liquidity while sticking true to ethos that (once) powered and united this industry. This year’s ETHPrague plans to confront exactly these existential challenges and steward community culture towards addressing outside criticism and external reality checks. Ethereum’s development, while adapting to market pressures, it always aimed to stick true to its core values in order to remain a technological bedrock for the future of humanity.

Topics discussed in this episode:
- The vision for ETH Prague
- Takeaways from main sessions
- High-level overview of ETH Prague
- The resurgence of Polkadot
- European crypto summer events
- The general state of the Ethereum ecosystem
- Celo’s transition to L2
- L2 liquidity fragmentation

Peter Thiel argued in his book 'Zero to One' that the way to build a great and highly profitable company is to build a monopoly. But with decentralized technologies, there is a real question whether these monopolies can be built or whether the monopolies will end up being publicly owned goods (like Bitcoin) that can't be monetized directly. 

William Mougayar, who is an experienced tech executive and angel investor, has been writing extensively about these issues and was one of the investors in OB1, the venture-backed company launched by the founders of the decentralized market place Open Bazaar. He joined us for a discussion of the cryptocurrency space, Ethereum, Open Bazaar and monetizing decentralized technologies. 

Topics covered included:
- Bitcoin as the new, thin cloud
- His long-term predictions about where the space is going
- What kind of business models are the most promising
- Why he chose to invest in OB1, the company behind Open Bazaar
- What the state of Venture Capital in the cryptocurrency space is

Permissionable blockchains have gained much attention from enterprise this past year, and specifically, the traditional fiance and FinTech sectors. As new protocols emerge and the technology is matures, it is becoming apparent they are simply a new class of database, one which integrates business logic (smart contracts) and a consensus layer (PoS, PoW, etc). 

Casey Kuhlman is the CEO of Eris Industries, a company which specialises in building permissioned blockchain systems for enterprise. Their aim is to deliver the technologies which enable companies to easily build and deploy applications which make use of blockchain and smart contract technologies.

Topics we discussed include:

- Casey’s impressive background as an engineer, Marine soldier, lawyer and startup founder
- Eris Industries and what the company is trying to achieve
- Permissionable blockchains and their usefulness in industrial applications
- Smart contracts, how to explain them and legal status
- How blockchains can be used to revolutionize the way organizations construct business processes
- The idea of Blockchains-as-a-Service
- The various use cases for blockchain technologies

As blockchain technologies mature, new protocol specifications are emerging, which take unique approaches to software design and how consensus is achieved. We have talked about Multchain and OpenChain in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus layer are completely independent. This provides added flexibility and allows for business logic to be written in practically any programming language. In addition, its unique approach to consensus, a round-robin Proof-of-Skate algorithm, is much better suited for permissioned blockchain scenarios than Proof-of-Work. 

Meher and Sebastien talk to Tendermint co-founders, Jae Kwon, Dustin Byington and Ethan Buchman, about this promising new blockchain protocol and how it is different from other projects we’ve seen so far.

Topics covered in this episode include:

- How Tendermint came to be and how it has evolved since its creation
- Smart contract programming and the Tendermint Socket Protocol (TMSP)
- How Tendermint makes use of the Ethereum Virtual Machine (EVM)
- Tendermint’s approach to PoS consensus and its scalability benefits
- Use case for permissioned and public blockchains
- Future plans and business models

The idea that in the future tokens will play a crucial role in networks and organizations to incentivize decentralized collaboration and reward contribution is not new. It's the original decentralized autonomous organization idea that has informed many projects that have been on the podcast (Swarm, Ethereum, Factom, Storj, etc). For Matan, the vision originally led to found decentralized ride-sharing application LaZooz. One year ago, he left LaZooz to found Backfeed, which is building the tools that so far have been missing to make mass collaboration without a central party possible. 

Topics covered included:
- How he became interested in blockchains and started the ridesharing application LaZooz
- Backfeed's vision for a social operating system for decentralized organizations
- The role of reputation, proof-of-value and tokens in Backfeed
- The applications Backfeed is currently building

The problem around content monetization is one which content producers are constantly trying to solve. At the core of this problem is a mismatch between supply and demand. Content, which is increasingly abundant, is captured by human attention, which is in limited supply. The volume of content being produced is growing at staggering rates while total human attention remains flat. 

Our guest, Maciej Olpinski, argues that the current content monetization model is outdated, broken and is in need of an overhaul. Previously at Google and YouTube, Maciej has a broad understanding content monetization models and lays out a vision for open marketplaces for attention using blockchains. He argues that content discovery systems like the Google Page Rank algorithm and Facebook's News Feed could be replaced by open networks based on the mechanics of Bitcoin. 

Topics covered in this episode include: 

- How the current content monetization model works and why it's broken
- The inner workings of content discovery
- The economics of content discovery
- Open marketplaces for attention and reputation
- New web-native business models for content discovery

For orthodox Bitcoiners central banks are often seen as the incarnation of evil. But , alas, in the case of two Carribean central banking economists the feeling of reprehension wasn't reciprocated. Winston Moore and Jeremy Stephen were formerly associated with the Central Bank of Barados and fascinated by the potential of cryptocurrencies, they explored the consequences of their central bank holding Bitcoin as part of their international reserves. They joined us for a discussion of central banking, the pecularities of monetary policy in a small island nation and what Bitcoin could bring to the equation.

Topics covered included:
- The function of central banks
- The role international reserves hold for central banks
- The peculiar challenges of central banks of small island nation states
- How speculative attacks on central banks work
- Why central banks may want to hold cryptocurrencies as part of their portfolio

Since he started blogging as Two Bit Idiot in 2013, Ryan Selkis has been both industry insider and industry critic. Consistently calling out excesses and abuses, but also maintaining his sights on the long-term potential. 

He recently founded Messari, a project that aims to bring more transparency and fairness to the industry. Messari has narrowed in on siloed, inaccurate and incomplete data as a key factor that allows insiders to profit at the expense of the public. We talked about the various ways in which Messari tackles that problem, ranging from a community-led effort to gather project data to the ambitious goal of a token-curated registry of stand-up projects.

Topics discussed in this episode:
- Ryan's start into the crypto industry as pseudonymous blogger Two Bit Idiot
- His insights from being the Digital Currency Group's first employee
- CoinDesk and the challenges of journalism in crypto
- Why poor and inaccurate information benefits industry insiders at the expense of retail investors
- Messari's mission to lead a self-regulatory effort for the crypto industry
- How an open, distributed crypto data library could help create a fairer playing field
- The plans for Messari's token-curated registry of projects following reporting standards
- The economics and game theory around the Messari token and TCR

#247 Ryan Selkis: Messari - Bringing Transparency and Self-Regulation to the Blockchain Industry

The concept of a decentralized exchange has been a holy grail in the cryptocurrency space for many years. Many attempts have been made, but most decentralized exchanges suffered from central points of failure, poor user experience and little liquidity.

Launched during Ethereum's DevCon 2018, Uniswap is one of the first fully decentralized exchanges and managed to become the leading DEX very fast. We were joined by Uniswap Founder Hayden Adams to discuss Uniswap's unique model, the different participants in the protocol and the importance of decentralized exchanges for the blockchain space.

Topics discussed in this episode:
- How Hayden's exploratory project to learn smart contract development took off and became Uniswap
- How Uniswap works and its different participants
- The advantage of an automated exchange instead of using order books
- The role of liquidity providers in Uniswap
- Feedback loops that can make Uniswap markets popular or collapse
- The challenging economics of liquidity shares
- Addressing Arthur Hayes' criticism of decentralized exchanges
- Why Uniswap didn't create a tokeneconomic monetization model
