Two Bits
A Reframing of the Blockchain Trilemma
By: Jeremy Koch
We are all familiar with the idea of the blockchain trilemma: the challenge of simultaneously achieving decentralization, security, and scalability in a blockchain network.
Typically, improving one compromises the others.
Most live blockchains today are subject to worse performance in one of these areas. While talking with industry leaders, I have stumbled upon not one, but two new solutions that have flipped the traditional trilemma on its head. Both of these projects challenge the notion that the trilemma even really exists. This new belief stems from the trilemma not actually being a technological constraint but rather an assumption on how decentralized systems had to be built.
With this in mind, these projects were able to think from true first principles and create a technical solution to a problem long considered unsolvable.
In my experience, good ideas come in pairs, so seeing two teams tackle the same problem at the same time does not shock me. Rather, it shows the confluence that we are on the right track—and competition will only accelerate the path to the best one.
The two projects are Supercritical and Optimum.
TLDR of Supercritical
The Supercritical litepaper introduces a blockchain architecture designed to overcome the trilemma through five key innovations:
Stateless Node Architecture: By decoupling transaction execution from state consensus, this design allows for the real-time processing of billions of transactions without an upper throughput limit.
Decentralized Hardware Security Module (dHSM): This compute layer provides Byzantine Fault-Tolerant (BFT) security and confidentiality at Web2 performance levels using standard hardware.
Globally Addressable Memory Bits (GAMBit): This memory model structures blockchain state akin to encrypted computer RAM, facilitating the parallel execution of millions of smart contracts.
Nash Consensus: A consensus mechanism that achieves global state agreement in real-time through local memory-cell level consensus, moving away from traditional block-based methods.
TypeScript-Based Development: By enabling blockchain development in TypeScript, it becomes accessible to a broader developer community without sacrificing performance, thanks to the architecture’s scalability.
TLDR of Optimum
Optimum addresses the trilemma through the creation of Random Linear Network Coding (RLNC), a technology developed at MIT and previously applied in fields like 5G and satellite communications. The integration of RLNC with existing blockchains, like Ethereum, aims to overcome critical scalability bottlenecks without compromising on decentralization or security.
Efficient Data Transmission: RLNC encodes data into mathematical equations, which allows for faster and more reliable transmission across the network. This reduces bandwidth usage and enhances overall network performance. 
Reduced Bandwidth Usage: By optimizing data encoding, RLNC minimizes the amount of data that needs to be transmitted, leading to more efficient use of network resources and lowering barriers to entry for nodes participating in the network. 
Enhanced Reliability: The coding technique ensures that even if some data packets are lost during transmission, the original information can still be reconstructed, thereby improving the reliability and security of data delivery within the decentralized network.
Both teams are challenging long-held assumptions by rethinking blockchain architecture from the ground up. Supercritical’s compute and memory models, paired with a stateless architecture and Nash Consensus, offer a radically new blueprint for performance at scale. Optimum, on the other hand, introduces RLNC technology to upgrade how data flows through existing chains, paving a path to scalability without breaking the core principles of decentralization and security.
If these solutions live up to their promise, they won’t just solve the trilemma; they’ll make us question whether it was ever real in the first place.
The era of blockchain tradeoffs might finally be coming to an end.
