Interoperability is the holy grail for a multi-chain future or the ‘internet of blockchains’. However, while IBC (inter-blockchain communication protocol) revolutionised permissionless cross-chain transfers, it was Skip Protocol’s Go API that took advantage of Cosmos’ infrastructure (and its numerous messaging protocols), to create an end-to-end interoperability platform, allowing developers to design seamless cross-chain user experiences.

We were joined by Sam Hart, head of product at Skip Protocol, to discuss the challenges of interoperability across Cosmos & Ethereum, and how Skip:Go API & Skip:Connect push the crosschain boundaries towards end user adoption.

Topics covered in this episode:

• Sam’s background
• The Other Internet
• Skip Protocol: bringing seamless interoperability to Cosmos
• Monetization for Skip:Connect & Skip:Go
• The Skip:Connect oracle and how Cosmos chains pull data
• Cross-chain MEV
• MEV blockers
• Ethereum vs. Cosmos ecosystem development and activity
• Ethereum bridges vs. Cosmos IBC
• Cross-chain interoperability
• Skip’s multi-chain expansion

In this day and age, privacy and confidentiality are more important than ever. Advancements in the cryptographic research of zero knowledge proofs (ZKPs), fully homomorphic encryption (FHE) and multi-party computation (MPC) paved the way for computational integrity and confidential computing. While FHE allows for computation to be performed on encrypted data without the need for prior decryption, it is MPC that enables compliance with regulations (e.g. AML). Arcium aims to build a global super computer for parallelised confidential computing, powered by custom MXEs (multi-party computation execution environments).

• Confidentiality & decentralised compliance

The future is multi-chain, scalable and modular. However, while Cosmos’ IBC set the standard for interoperability, Ethereum’s L2 shift revealed a huge problem of liquidity fragmentation across the many rollups fighting for market share. Polymer aims to bridge the two ecosystems and bring the best of both worlds: Ethereum’s native liquidity and Cosmos’ interoperability, through a modular framework using the OP-stack and IBC.

• Bo’s background and the evolution of Polymer
• Scaling limits of L1s vs. L2s
• The ‘endgame’ for rollup frameworks
• IBC
• Interoperability & network topology: 70’s/80’s vs. blockchains

Self-custodial wallets often represent the first point of contact for crypto users that venture away from centralised exchanges. As a result, their security and user experience should be paramount. This often explained Metamask’s first mover advantage and the users’ reluctance to change. However, as infrastructure evolves, new wallets are equipped from the get-go with features that are designed for normie adoption, such as: account abstraction, gas fee abstraction, easier on- and off-ramp, etc. Zeal was envisioned as a day-to-day wallet solution, allowing users true freedom to transact, both on-chain, as well as off-chain (i.e. real world spendings).

Topics covered in this episode:

• Hannes’ background
• Existing wallet solutions and Zeal’s userbase
• Wallet UX, account abstraction and passkeys
• Security assumptions and passkey recovery
• Smart contract interactions
• Zeal’s mobile-first focus
• IBAN & Gnosis Pay integrations

As the crypto industry matures, more sophisticated market participants become involved. As a result, risk management and hedging will evolve to levels seen in TradFi. However, regardless of the preferred market activity, when interacting with a blockchain, every actor competes for the same limited blockspace. Based on demand levels, the cost for securing that blockspace can fluctuate (in the form of miner fees for Bitcoin transactions, or gas fees for PoS blockchains). Therefore, a particular niche of power users could lower these costs by reserving blockspace in advance of elevated demand levels. Alkimiya set out to build just that - a marketplace for blockspace.

Topics covered in this episode:

• Leo’s background
• The vision behind Alkimia
• Market participants for blockspace
• Hedging costs
• Use cases on Ethereum
• Proposer-Builder Separation and preconfirmations
• Reserving blockspace

The saying goes that knowledge is power, and this perfectly applies to blockchains due to their innate transparency and immutability. However, raw data could seem, at first, unusable. This is where analytics companies, such as Nansen, play a major role in demystifying blockchain data by labelling it. In turn, curated data holds value as it can give an edge to traders, by tracking ‘smart money’ wallets. In the age of AI, most of the heavy lifting of data analysis is performed by LLMs, but human input is equally valuable for discerning nuances and fine tuning the process.

Topics covered in this episode:

• Alex’s background, from AI to crypto
• Nansen’s values
• Querying blockchain data
• Supported chains
• Ensuring data accuracy
• Generating wallet labels
• The role of LLMs and AI
• Data privacy and monetisation
• On-chain transparency, privacy and ethics

In 2017, Vitalik Buterin defined the ‘Scalability Trilemma’ which consisted of 3 attributes that every blockchain had to balance depending on its intended use cases: decentralisation, scalability and security. While Ethereum sacrificed scalability in favour of security and decentralisation, others prioritised throughput over the other two. However, a solution was proposed, inspired from Web2 computer science - sharding. Despite the fact that Ethereum’s ossification and significant progress in zero knowledge research led to a shift in Ethereum’s roadmap away from execution sharding towards L2 rollups, there were other L1s that were designed from the get-go as sharded blockchains. One such example was Elrond, who implemented the beacon chain PoS consensus alongside a sharded execution layer. Their recent rebranding to MultiversX alludes to a multi-chain, interoperable ecosystem, in which sovereign chains can communicate in a similar manner to cross-shard transaction routing.

Topics covered in this episode:

• Lucian’s background and founding Elrond (MultiversX)
• Elrond’s validator & shard architecture
• Cross-shard composability
• VMs, smart contracts and transaction routing
• Self sovereignty and modularity

Web3’s decentralisation is currently limited to smart contracts as they can be verified on-chain. However, until scalability and UX become on par with that of Web2, the only realistic way for crypto to reach mass adoption is threw off-chain dApps. This creates the premise for a security bottleneck in the form of centralised APIs used for on-chain querying. Mel Project aims to expand on-chain security and decentralisation (consensus) to off-chain apps, basically achieving off-chain composability through trustless light clients. Earendil, the backbone of their ecosystem, designed to resist ISP-level censorship, is a decentralized anonymous communication and payment network that enables autonomous applications and true P2P protocols.

Topics covered in this episode:

• Eric’s background and founding Mel Project
• Why Ethereum came short
• Is Infura a security bottleneck?
• Liberating markets (and the Internet)

One of the OG flag bearers for decentralisation, Gnosis initially set out to build a prediction market on Ethereum. However, unlike the vibrant ecosystem of today, the early Ethereum days were barren. As a result, Gnosis team decided to build out their own infrastructure and tooling to suit their needs. Before long, tools such as Gnosis Safe, Zodiac, etc. were quickly adopted by the entire industry. Nowadays, since the foundation has been tried and tested, Gnosis 3.0 aims to focus on improving consumer dApp UX in order to facilitate widespread adoption.

• Gnosis’ background and vision
• Gnosis 3.0
• Gnosis DAO
• Capital allocation management
• How Gnosis Pay revolutionizes payment rails
• The ‘Baguette Conundrum’: privacy & regulatory compliance for on-chain payments
• The future of the EVM vs. modularity
