Ethereum, Arbitrum, and why L2 solutions are a mess

For those unfamiliar with the debate, Ethereum and Bitcoin have for years struggled with congestion and high fees arising from their failure to keep up with demand on their blockchains. This has in turn created opportunities for projects offering “on-top” solutions as a means to handle that extra demand. The result is a plethora of so-called layer-2, or L2, sidechains—Arbitrium, Optimism, and Polygon among them—that are intended to increase transaction capacity while keeping the chain orderly.

In the Bitcoin network, these efforts have largely focused around Lightning, a system of secured peer-to-peer channels that allow for quick and cheap transactions. In the case of Ethereum, developers have taken a more baroque approach that typically looks like this: A technical team claims to have a novel solution to scale Ethereum by capturing transactions on their network, and that idea is pitched to venture capitalists. But instead of integrating this software directly into the main protocol, so Ethereum as a network can scale, a new token—an L2 token—is issued to transact using this new software.

Does this have to happen? Well, no. Strictly speaking, there is nothing stopping Ethereum leadership from incorporating scaling solutions at the protocol level to lower its costs and make the network more efficient. But instead of working to make the scaling happen directly, the Ethereum crowd has instead relied on the L2 route. (It’s worth noting that Tezos, the blockchain I cofounded, recently deployed an L2 solution without introducing a token.)

While L2 solutions on Ethereum have succeeded in offering faster and cheaper transactions, their insistence on adding their own proprietary tokens add friction. To make matters worse, the L2 projects often rush to market with underdeveloped solutions, creating a reliance upon Ethereum contracts under their control and centralized oversight to address security issues later. While this tokenized approach funds development and generates hype, it quickly leads to disillusionment as inflated token market capitalizations fail to meet expectations.

So why does Ethereum continue to embrace these half-baked L2 solutions? Look no further than Sand Hill Road.

Traditionally, venture capitalists offer financing for new businesses—the word “venture” connoting newer, riskier investments, unlike those perhaps preferred by other private equity firms. VCs typically look to exit their positions through IPOs or acquisitions, often on five- or seven-year time horizons.

If VCs had a chance speed up their exits—the big moment everyone gets paid—to an order of months, you can bet they would leap on it. And so enter a new model facilitated by crypto.

In Crypto VC speak, exit strategies don’t come from the creation of a useful, flourishing business. Since 2018 or so, VCs have acted as providers of bridge capital to teams until a token is created and sold. It’s about short-term storytelling because, ultimately, the value of the token isn’t defensible. Often, it’s a solution in search of a problem or, in the case of scaling, a source of additional friction. The last two months have served as testament to the instability of L2 tokens for a variety of business reasons.

Last month, Coinbase announced it was launching an L2 solution based on Optimism. This was poetic: Optimism already has an unnecessary token and a staking mechanism for its distribution. Unfortunately, it lacks fraud proofs, or the basic security ingredient that makes a scaling solution more secure than a hope and a prayer. What we have here is a token in search of its own technology.

More recently, Arbitrum, an L2 on Ethereum that’s raised over $100 million from VCs such as Lightspeed, issued a governance token called ARB to justify its place outside the base Ethereum protocol. As part of its first “governing” act, the community was asked to vote on a proposal that would send 750 million of its tokens, worth around $1 billion, to its nonprofit foundation. When rank-and-file community members balked at this plan, the Arbitrum Foundation clarified that these funds were already being allocated—and, indeed, had been spent. It was a lucky day for those folks who gave them money last year in a private transaction, and virtually nobody else who bought into the gold-plated resumes of its founding team and the characterizations of their project.

Quite the arbitrage, indeed.

Scaling solutions that create more costs and hoops to jump through for users by issuing pernicious tokens aren’t solutions at all. Ethereum will evolve once it weens off venture capitalists and embraces a model that seeks to disintermediate, rather than subsidize, the well-heeled financiers of Web2.
