Apart from the many instances where cryptocurrency holders get socially engineered (hoodwinked) into turning over their crypto or their account credentials to extremely clever and tenacious hackers (essentially, “user error”), the leading cause of cryptocurrency theft is a vulnerable cross-chain bridge. In fact, on the same day this interview with LayerZero co-founder and CEO Bryan Pellegrino was recorded at the Harvard Blockchain Conference, the AllBridge cross-chain bridge was exploited for approximately $574,000.

According to Pellegrino, approximately $4 billion has been stolen via cross-chain bridge exploits since late 2021. Pellegrino was at Harvard University’s annual blockchain conference to talk about what it takes to secure communications between chains—an area of particular interest to enterprises because, as enterprises are already learning, in the same way, that many businesses have to work with multiple fiat currencies, there’s a high likelihood that they’ll also have to deal with multiple cryptocurrencies which in turn means they’ll have to simultaneously deal with multiple public distributed ledgers. Secure inter-chain communication will be an absolute must.

As opposed to relying on smart contracts to handle cross-chain bridge management at the so-called application layer of blockchain, Pellegrino’s company has been focused on handling cross-chain bridging at the protocol layer; a layer that, like the Internet’s TCP/IP protocol, lives below the blockchain layer itself. Thus, the company’s name “LayerZero” (an implication that the lowest layer in the software stack where a blockchain exists is at layer 1, an idea that aligns with the way many different public distributed ledgers are described as “L1s”). 

While he was at Harvard’s Blockchain Conference, Pellegrino told BlockchainJournal.com editor-in-chief David Berlind that LayerZero has successfully secured over $7 billion, has over 35,000 applications running on its test net, with 3,500 apps now in production on the LayerZero main net. Said Pellegrino of LayerZero’s industrial strength, “You take a look at [which venture capitalists’] confidence have we [have] won; Sequoia, Andreessen, all these groups have made single bets in the space, and that bet has been on us.”

Aside from operating at the protocol level, what’s LayerZero’s secret to success? Well for starters, all of the code behind LayerZero has been purpose-built from scratch. Beyond that, are three convictions that are sacrosanct to everything LayerZero does; immutability, permissionlessness, and resistance to censorship.

Why LayerZero Is A Contender For Enterprises In Need Of Cross-Chain Bridges

Blockchains are secured through the economic incentives offered to their validators/miners. The more robust the network effect among validators, the more difficult it is for that blockchain to be compromised. However, building a truly decentralised and reliable validator set is not a trivial task. As a result, hub and spoke ecosystem designs like Cosmos’ (and even Polkadot’s), aim to share the main hub’s validator set and security to their ‘consumer’ chains (parachains in Polkadot’s case). Neutron relies on interchain queries, interchain accounts and interchain (replicated) security to deliver the most secure CosmWasm smart contract platform in the Cosmos ecosystem. 

We were joined by Avril Dutheil, GM at Neutron, to discuss Neutron’s smart contract platform and how it leverages replicated security (ICS) and interchain accounts (ICA).

Topics discussed in this episode:
- Avril’s background and the value prop behind Neutron
- Practical examples
- Interchain accounts and different use cases
- Interchain security
- Atom hub vs. Polkadot relay chain. Onboarding and security models
- Offboarding Cosmos consumer chains
- Replicated security vs. Modular blockchains
- Neutron’s token utility and governance

#504 Avril Dutheil: Neutron – Interchain Smart Contracts on Cosmos

"From the very beginning, Cosmos set out to provide an alternative to the monolithic blockchain architecture proposed by Ethereum. Cosmos SDK was the cornerstone of this vision, as it allowed developers to spin up blockchains effortlessly. Its modularity enabled custom, self-sovereign chains to become a reality. And, instead of being a jack of all trades, those chains were centred around a sole purpose, thus transforming them into appchains. In turn, as the ecosystem grew, appchains had to be interoperable with one another, but this was already a core feature of Cosmos, via IBC. Before Ethereum’s rollup-centric roadmap, appchains were thought to be a much-needed scaling solution. However, with the advancements of zero knowledge technology, the Cosmos SDK now faces another set of challenges as it navigates the market demand for L2 scaling solutions.

We were joined by Marko Baricevic, Cosmos SDK product lead, to discuss the development philosophy behind the Cosmos Hub and how appchains evolved over time.

Topics discussed in this episode:
- Marko’s background
- Cosmos SDK’s history and high-level overview
- Cosmos SDK modules and VMs
- Ethereum’s & Cosmos’ development philosophies
- Cosmos SDK value prop and use cases
- Cosmos SDK vs. other frameworks (e.g. Substrate)
- Token value accrual and the fragmentation dilemma
- Using the Cosmos SDK to build rollups
- Cosmos SDK vs. Avalanche’s HyperSDK
- Adoption of fraud proofs and validity proofs by the Cosmos SDK

CHART THE COURSE PODCAST EP 61 - TOP NORMIE

𝐃𝐫𝐞𝐚𝐦 𝐃𝐚𝐲𝐬 @dreamdays69  is a DJ, party thrower, and producer that lives in Austin, Texas USA. They enjoy playing sets that focus on "attitude and emotion." They prefer their music and parties to be more rugged and unrefined, and they view dance music through a DIY subversive lens. They play often in Texas and are known for long marathon sets that go across genres and boundaries. In Austin they throw a monthly warehouse rave called Body Mechanics. They have been going for over four years and are going strong! 

Deep in the middle of conservative cowboy Texas, Body Mechanics provides a space of refuge for the freaks. This mix has a lot of ebm mixed with some wave, electro, synth pop, post punk, and some wildcards as well. There are also a few original Dream Days tracks (two of which are coming out this summer) and an acapella by Daniel Johnston at the end; who is an Austin hero. Pop it on your favorite speaker and be transported to a late night sleazy warehouse rave in Texas.
