What Is The Blockchain Storage Trilemma and How Do We Solve It?

As a seasoned analyst with years of experience in the blockchain industry, I can confidently say that the blockchain storage trilemma is not just another buzzword but a significant challenge that developers must overcome to unlock the full potential of web3.


You’ve heard of the blockchain trilemma describing the challenge of simultaneously achieving three critical objectives in designing a crypto network: security, decentralization, and scalability. As the rule goes, achieving all three at once is extremely difficult, with most blockchains forced to prioritize two at the expense of the third.

As a crypto investor, have you ever pondered over the blockchain storage trilemma? If not, don’t worry, it’s not something everyone is familiar with, except perhaps those deeply involved in developing web3 storage solutions. However, understanding this concept can provide valuable insights into the difficulties faced by these developers and the progress they are making to tackle this lesser-known challenge within the blockchain world.

To be effective, a decentralized storage system must have scalability, native support for smart contracts, and random access capabilities. While it may seem challenging to incorporate all three features at once, it’s not impossible. Let’s delve deeper into how this is implemented and why it’s crucial in the development of blockchain-based storage systems.

Achieving the Impossible 

Designers of various systems, including blockchains, often need to make compromises due to specific requirements and competition for market share within their respective domains. For instance, blockchain systems prioritize certain characteristics such as decentralization, security, scalability, or energy efficiency over others. As a result, these trade-offs become crucial considerations.

From a crypto investor’s perspective, delving into the intricacies of blockchain storage isn’t essential, but grasping its fundamental principles can be quite beneficial. As we witness an escalating number of dApps and their data requirements growing exponentially, decentralized storage assumes paramount importance. The advent of Web3 necessitates access to specialized storage that empowers L1s and L2s to accommodate dApps without causing congestion on the main chain.

As a researcher delving into the realm of blockchain technology, I find myself pondering over the question: Is it feasible to comprehensively resolve the Scalability Trilemma that plagues our current blockchain systems? Or, could it be that achieving a 2 out of 3 compromise – a partial solution – is all we can realistically strive for, similar to other well-known scalability dilemmas in the field of blockchain?

Tackling the Toughest Trilemma

The three cores comprising the storage trilemma can be broken down as follows:

Scalability in terms of storage refers to the ability to accommodate vast amounts of data, essentially up to unlimited storage or at least exabytes (a billion gigabytes), considering we’re in the age of decentralized gigabyte storage. As the data needs of dapps escalate significantly due to applications like AI, it’s crucial for web3 solutions to be prepared to handle massive data influxes – that is, they should be able to deliver data by the bucketful or precisely, exabytes’ worth.

Directly integrating data onto decentralized file storage networks is useful, but what truly sets things apart is when this data can be seamlessly incorporated into blockchain-based smart contracts like Ethereum and Solana. This allows native dApps to access the data in real-time directly. Native storage is more efficient to query since it’s optimized for the specific network being used, which becomes crucial for managing complex dApps that process massive amounts of data and produce outputs as smart contracts.

From an analyst’s perspective: In the world of decentralized networks, data isn’t merely deposited for long-term preservation; it’s designed to be active and accessible on demand. To achieve this, data must be stored in a manner that supports real-time interactions with applications like dapps. Merely granting file-level access isn’t sufficient; the web3 storage system should offer random access similar to a conventional computer hard drive for seamless, dynamic usage.

The State of Storage Today

Current web3 storage systems like IPFS and Arweave excel in aspects such as decentralization and security, which are crucial for blockchain infrastructure. However, they fall short when it comes to scalability, smart contract compatibility, and random access. Many existing decentralized storage solutions struggle with queries due to their design for holding files or archives. They also tend to become costly when data exceeds gigabytes, reaching terabytes or exabytes.

Among the existing storage solutions, it appears that Xandeum, the Solana project, is the one that excels in all three aspects of the storage trilemma. Xandeum is designed to accommodate vast amounts of data and seamlessly integrate with Solana smart contracts. Additionally, it allows for swift data retrieval, facilitating random access. The comparison between Solana as a home computer and Xandeum as its complementary hard drive, providing the necessary storage specifications, is quite apt.

Instead of Solana, blockchain technology exceeds its size, and for other first-layer (L1) chains to attain this level of data storage, specialized solutions are essential. These solutions should be tailored to the specific programming languages used by each network, such as Solidity or Rust. This customization is crucial to improving decentralized applications while allowing blockchain networks to expand in capacity. For Ethereum Virtual Machine (EVM) networks, this can be accomplished through integrations with existing services like Arweave, which boost their performance, particularly in areas of speed and smart contract compatibility.

Solving blockchain trilemma challenges can be quite a tough nut to crack, but the benefits that come with it definitely outweigh the effort. For developers who manage to grasp the concept of decentralized data storage, the potential payoff – much like the capacity itself – has no ceiling.
