Ethereum needs layer 2 blockchains to help deal with its “shortcomings on cost and throughput,” though those same scaling products could leech revenue from the network as they become “competitive rather than complementary,” COINBASE (COIN) said in a research report Monday.
“It's feasible that Layer 2s could become the application layers hosting the bulk of economic activity while Ethereum exists exclusively to store transaction data,” wrote David Duong, head of institutional research at Coinbase.
A layer 1 network is the base layer, or the underlying infrastructure of a blockchain. Layer 2 refers to a set of off-chain systems or separate blockchains built on top of layer 1s. A decentralized application (dapp) is a digital app that uses blockchain technology to keep users’ data out of the hands of the organizations behind it.
The future of layer 2s could be a “zero-sum game” because the layer 2 that houses the majority of dapps could “power the entirety of the Ethereum ecosystem,” the report said. There is about $68.9 billion in total value locked (TVL) on Ethereum compared with $5.2 billion across layer 2s, the report said.
While the TVL in layer 2s is relatively small, the implementation of zero knowledge Ethereum Virtual Machines (zkEVM) is looking more achievable and could lead to “major traction” in layer 2 growth, the note said.
Coinbase says that if more user activity moves to layer 2s and these blockchains need their own tokens to enable transactions, this could reduce the staking yields to Ethereum validators , cutting their revenue. That could reduce staking on the platform and increase the amount of ether (ETH) circulating, potentially damaging the cryptocurrency’s price. A decline in validators could also have a negative impact on the overall security of the network, the report said.
For the time being, transacting on the Ethereum mainnet will provide a solution for users who need or value “security over speed,” the report said, noting that losses on cross-chain bridge exploits have reached $2 billion this year.
More activity accumulating to an application on layer 2 would reduce congestion and fees on the layer 1 and this could result in better price discovery for ETH, the note said.
