The first generation of blockchain achieved something extraordinary.

Bitcoin gives us digital scarcity. Ethereum opens programmable money. Solana proves that high-speed networks are possible. Each value chain carves its own value proposition in a broader ecosystem. These achievements lay the foundation for a trillion-dollar industry and demonstrate that decentralized coordination on a large scale is possible.

However, they were designed for different eras. Bitcoin was created to prove that peer-to-peer currency could exist. The goal of Ethereum is to show that smart contracts are viable. Neither was created with billions of daily users in mind. Along with the acceleration of adoption, the blockchain technology market is projected to reach $1.4 trillion by 2030. The main challenge is how quickly these systems can evolve without costly R&D for years and the consequences of redesigning their foundations.

That’s where modular infrastructure transforms the economy of progress.

Blockchain Scalability Costs

Scaling or upgrading the chain is complex and resource-intensive. Throughput limits remain high: Bitcoin processes around seven transactions per second, Ethereum around fifteen, while traditional payment systems like Visa operate at over 24,000 transactions. When demand surges, costs skyrocket as congestion is the only mechanism available to ration limited block space.

Monolithic design exacerbates this problem. By combining execution, consensus, settlement, and data availability, every upgrade becomes harder to implement and riskier to deploy. Hard forks can fracture communities, and incremental changes are often limited by the weakest system components.

Fragmented User Experience

User experience is also still inadequate. Setting up wallets, navigating approvals, and paying various fees makes the onboarding process difficult. In practice, interacting with blockchain applications is still far more complicated than the smooth sign-up processes and embedded payments consumers expect from Web2 platforms.

Ask someone unfamiliar with decentralized financial products to transact on the DeFi protocol and see what happens. The current UX is lacking:

  • Install browser extension wallet

  • Buy ETH on a centralized exchange (if your jurisdiction allows it)

  • Transfer to your hot wallet (pay gas)

  • Approve token spending (pay gas)

  • Execute your transaction (pay more gas)

  • Hopefully the network doesn’t congest

  • Pray that you don’t mistype the contract address

We have made using blockchain harder than filing taxes.

Security and Resilience Gaps

Resilience adds additional costs. Solana, despite having impressive throughput, has experienced several network outages; BSC continues to face concerns around centralization; and Ethereum itself requires emergency consensus patches. These incidents highlight the difficulties in pushing monolithic systems beyond their design limits, and the reality that performance often sacrifices reliability. Every improvement absorbs capital and engineering talent that could be directed towards ecosystem growth.

Why Modularity Matters

The industry is now moving towards modular design, where execution, consensus, settlement, and data availability operate as separate layers. This separation reduces costs, accelerates iteration, and allows each component to optimize its function, rather than being constrained by the system as a whole.

The benefits are significant. Upgrades can be implemented without jeopardizing the entire network. Workloads can be scaled horizontally across layers, rather than bottlenecking in one place. Chains gain flexibility to specialize, whether in consumer payments, institutional settlement, or high-frequency trading. And most importantly, development teams can dedicate their resources to ecosystem growth and application design, rather than rebuilding database layers for years.

This is the same development that software engineering achieved when transitioning from monolithic programs to microservices, APIs, and distributed architectures. The lesson learned is that modularity enhances efficiency and resilience, and blockchain infrastructure is now undergoing the same transition.

Altius Approach

At Altius Labs, we focus on the execution layer, as this is where performance bottlenecks are most pronounced and where the highest improvement opportunities lie. Our parallel architecture prioritizing memory processes thousands of transactions simultaneously while maintaining consistency, delivering enterprise-grade throughput connected to existing blockchains without disruptive rewrites.

For ecosystems, this means scaling upgrades without migrations for years; for new chains, it means launching with production-level capabilities from the start.

This work is deep within the stack, often invisible to end users, and that is the crux of the matter. Chains should be free to allocate their resources to what makes them unique, whether that's developer communities, ecosystem growth, or applications; without having to spend years updating their core infrastructure.

We believe in a multi-chain future where various blockchains specialize in different roles, but all benefit from infrastructure that reduces costs and accelerates scalability processes. This pie will continue to grow, and modular architecture is the foundation that ensures every participant can take part in that expansion.

Conclusion

Blockchains are racing to evolve into roles that can deliver the highest value. Modular infrastructure offers the foundation for this transition, enabling chains to perform upgrades seamlessly, serving billions of users, and increasing industry share in the global economy.

The next decade will belong to systems that make blockchain as reliable, scalable, and non-disruptive as the internet itself.
