Layer-1 blockchains are increasingly caught in a tug-of-war between maintaining decentralization and meeting user demand for speed and scalability, according to Injective CEO Eric Chen. Speaking on Cointelegraph’s Chain Reaction podcast, Chen explained that as adoption grows—driven by institutional interest and agentic AI finance—the pressure to sacrifice core blockchain principles will intensify.
“In our mind, it’s essentially about finding scaling opportunities without compromising the fundamental pillars that define what a blockchain is,” Chen said. He emphasized that while scaling is necessary, the industry must avoid the easy path of centralization, which could create single points of failure. “If that one server has a certain fault, the entire chain goes down,” he warned.
The expanding Layer-1 landscape
The Layer-1 ecosystem has grown far beyond Bitcoin and Ethereum. Today, networks like Injective, Solana, Avalanche, and many others compete for market share, each offering different tradeoffs between decentralization, security, and scalability. Injective, an interoperable blockchain designed for DeFi applications, focuses on optimizing the entire chain without simply reducing block time. Chen pointed to “scaling venues” with dedicated zones and layer-2 solutions as ways to handle high-demand transactions efficiently.
This tension is not new. The blockchain trilemma, a term coined by Ethereum’s Vitalik Buterin, states that a blockchain can only fully optimize two of three properties: decentralization, security, and scalability. Pushing too hard on scalability often forces compromises on decentralization. For example, increasing transaction throughput by reducing the number of validators or using a single leader can weaken the network’s resistance to censorship and attacks.
Historical context: From Bitcoin to modern L1s
Bitcoin, the first blockchain, prioritized decentralization and security over scalability. Its proof-of-work consensus and long block times ensured a robust, censorship-resistant network, but throughput is limited to about seven transactions per second. Ethereum improved on scalability but still faces congestion and high gas fees during peak usage. Later L1s like Solana and BSC boosted throughput by adopting faster consensus mechanisms and fewer validators, but at the cost of centralization. Solana experienced multiple outages due to its single-leader validator model.
Injective launched in 2020 as a Cosmos-based chain with zero gas fees and fast finality. Its design uses a proof-of-stake model with a limited set of validators, balancing speed and decentralization. Chen believes that future L1s will need to innovate around “scaling venues”—specialized zones or sidechains that can process specific transaction types without burdening the main chain. This approach echoes the broader trend toward modular blockchain architectures, where execution, consensus, and data availability are separated.
The institutional push and its risks
Institutional adoption, once a distant goal, is now accelerating. Banks, asset managers, and even governments are exploring blockchain for settlement, tokenization, and payments. This brings billions of dollars in transaction volume, but also demands high speed and low latency. Traditional finance operates with milliseconds finality, whereas many blockchains still take seconds or minutes.
Chen argued that institutions may be willing to accept some centralization if it means better performance, but he cautioned against this. “Centralization might be a very easy choice to move everyone in the same data warehouse, or literally have a leader validator that calls all the shots for everyone,” he noted. However, that approach undermines the trustless nature that makes blockchain valuable.
Agentic AI finance: A new pressure point
Another emerging factor is the rise of agentic AI—autonomous agents that execute financial transactions on behalf of users. These bots require fast, cheap, and reliable blockchain infrastructure. If a network is slow or expensive, AI agents will simply migrate to faster, more centralized alternatives. Chen suggested that L1s must prepare for a surge in machine-to-machine transactions, which could dwarf human-driven volume.
This trend is already visible in decentralized finance (DeFi), where automated market makers and lending protocols execute millions of transactions daily. As AI agents become more sophisticated, they will demand sub-second finality and high throughput. Without careful planning, L1s could face a choice between centralizing to accommodate AI or losing market share to more scalable competitors.
Scaling without centralizing: Injective’s approach
Injective aims to address the trilemma through its unique architecture. It uses a interoperable framework that allows developers to build custom DeFi modules. The network achieves high throughput by processing transactions off-chain and finalizing them on-chain via a consensus mechanism called Tendermint. Chen highlighted that Injective is exploring “scaling venues,” which are specialized execution environments for high-demand applications, such as perpetual swaps or options trading.
These venues can operate as layer-2 rollups or sidechains, inheriting security from the main chain while offering faster processing. This approach avoids the need to alter core consensus rules or reduce validator counts. It also allows the network to scale horizontally by adding more venues as demand grows, without centralizing control.
Chen also noted that Injective is working on reducing block times further without compromising decentralization. Currently, the network achieves about 2-second block times with 50 validators. Further optimization could bring it under 1 second while maintaining a distributed validator set.
Competing visions for the future of L1s
Other L1 projects are taking different paths. Ethereum focuses on layer-2 scaling through rollups, hoping to keep its base layer highly decentralized while offloading execution. Solana pursues a monolithic approach with high throughput through a single shard, but its outages raise questions about whether decentralization is being sacrificed. Cosmos, which Injective is built on, promotes an “internet of blockchains” where each application runs its own sovereign chain, allowing customization without affecting the whole ecosystem.
Chen believes that no single model will dominate. “It’s always a constant tug-of-war,” he said, “and it’s about keeping the fundamental pillars and then kind of seeing where the space moves.” He expects that L1s will converge on hybrid models that combine elements of modular and monolithic designs, adapting to specific use cases.
The debate is not purely technical; it has economic and governance implications. Centralized chains are easier to upgrade and steer, but they are vulnerable to regulation and censorship. Decentralized chains are more resilient but slower to adapt. For DeFi applications that rely on trustlessness, any compromise on decentralization could erode user confidence.
Regulatory and security considerations
As blockchain adoption grows, regulators are paying closer attention. Centralized networks may face less scrutiny because they have clear points of control, but they also risk being classified as securities or subject to direct oversight. Decentralized networks, on the other hand, can argue they are not under anyone’s control, making them harder to regulate. This legal distinction could influence how L1s evolve.
Security is another dimension. Decentralized networks distribute risk across many validators, making them resistant to coordinated attacks. Centralized networks have a smaller attack surface but a single point of failure—if a hacker compromises the leader validator, the entire network can be disrupted. Chen warned that the ease of centralization is deceptive: “It might be a very easy choice… but if that one server has a certain fault, the entire chain goes down.”
Recent incidents illustrate the risks. In 2024, a large L1 experienced a 6-hour outage due to a faulty validator update. While the network recovered, users lost access to funds and applications during that window. Such events undermine trust and highlight the need for robust decentralization.
The role of community governance
Decentralization also manifests in governance. Many L1s have on-chain governance mechanisms that allow token holders to vote on protocol upgrades. However, as networks scale, voter apathy and whale influence can skew decisions. Chen noted that Injective’s governance is designed to be inclusive, with proposals requiring broad support. He believes that community-driven decisions are essential to maintaining trust.
But governance can slow down innovation. In highly centralized chains, the core team can implement changes quickly, while decentralized communities often debate for weeks. This tradeoff is another dimension of the trilemma: speed of iteration vs. resilience to capture.
Chen suggested that L1s could adopt “progressive decentralization”—starting with a more centralized development phase and gradually distributing control as the network matures. This model has been used by projects like Solana and Avalanche, though critics argue that it can lock in initial power imbalances.
Looking ahead: The next decade for L1s
In the next five to ten years, the blockchain landscape will likely see consolidation. Some L1s will fail because they cannot attract enough developers or users. Others will thrive by solving the trilemma in novel ways. Chen is optimistic about Injective’s prospects, citing its strong community and technical roadmap. “We’re focused on building infrastructure that allows developers to create whatever they want, without worrying about scalability bottlenecks,” he said.
The ongoing tug-of-war between decentralization and scalability will define the evolution of Layer-1 blockchains. As adoption accelerates, the choices made today will determine whether blockchain fulfills its promise of a trustless financial system or becomes just another centralized platform with a crypto veneer. Chen’s message is clear: innovation must preserve the core pillars, even as the market demands more speed and efficiency.
