According to Injective CEO Eric Chen, Layer 1 blockchains will come under increasing pressure to sacrifice decentralization for speed and efficiency as apply of the technology increases.
This pressure will come from the need to meet users’ desires for faster speeds or larger block space for greater bandwidth, Chen told Cointelegraph’s Chain Reaction podcast on Monday.
“Our view is that it is fundamentally about finding opportunities to scale without compromising the fundamental pillars that define what blockchain is,” he said.
As blockchain adoption accelerates due to institutional adoption and agentic AI funding, this tension will soon be tested on a much larger scale. Part of the original idea behind cryptocurrencies was to create a “trustless” financial system in which individuals could transact without relying on established intermediaries.
Centralization carries risks
Chen said centralization is the effortless way out — it could be a very, very effortless choice to move everyone to the same data warehouse or literally have a validator leader calling the shots — but he warns that it creates a single point of failure: “If this one server has a particular failure, the whole chain goes down.”

Chen added this for injection — Layer 1 interoperable blockchain designed for DeFi applications — the idea is to “find ways to optimize the entire chain” and there are other ways to do this without reducing block times.
One of the options he suggested was “scaling spots,” where there are “dedicated zones” and Layer 2 scaling to ensure all high-demand transactions can be fulfilled.
“It’s always a constant tug of war and it’s about maintaining the basic pillars and then seeing where the space moves.”
The blockchain trilemma remains a challenge
It is said that the ideal blockchain boasts three elements: security, decentralization and scalability. The principle of the blockchain trilemma is that it is possible to fully optimize only two of the three properties at a time.
Decentralization means there is no single point of control and many independent participants validate the network. Security means resistance to attacks, fraud and manipulation. Scalability means the ability to handle huge transaction volumes at high speeds.
Pushing too strenuous on any one of them, e.g. scalability, will sacrifice another one, e.g decentralizationChen said.
