Celestia's Core Values: Bridging Off-chain Governance with User-centric Network

Mustafa Al-Bassam, the trust-minimization engineer and co-founder of Celestia, elucidated the five cornerstone values governing the social layer of the Celestia network in a comprehensive post on 12th October 2023. These precepts are devised to bolster the trust-minimizing facet of the Celestia blockchain, ensuring a well-aligned community capable of consensus on protocol amendments.

The pivotal essence of Celestia’s social layer is the belief that off-chain governance supersedes token-holder governance. As Al-Bassam quoted David D. Clark of IETF, “We reject kings, presidents and voting. We believe in rough consensus and running code.” This framework postulates that no faction, regardless of size, can unilaterally alter or breach protocol rules. The canonical fork, along with the state transition function of Celestia’s blockchain, is fundamentally governed by its social and ecosystem layers, not by token voting or validators.

Celestia places users at the zenith of its network hierarchy. This approach negates the necessity for users to place trust in centralized endpoints or committees, which are often seen as breaches of decentralization and Web3 principles. In lieu, the Celestia community has been ardently developing and promoting the use of trust-minimized light nodes. These nodes empower users to independently verify the chain’s integrity employing data availability sampling techniques.

Embracing a positive-sum crypto ecosystem, Celestia’s community champions modularism over maximalism. The base layer of Celestia is crafted as a generalized data availability layer, maintaining neutrality towards all execution environments and applications built atop it. This stance prevents any undue favor towards a particular execution environment that might hamper experimentation with others.

Acknowledging itself as a public good, Celestia aims for economic sustainability by delivering high-grade blockspace at scale, targeting a user base in billions instead of fostering artificial resource scarcity. The pricing of resources is strategized to achieve economic sustainability without being excessively extractive.

A cardinal design decision of Celestia is the minimization of on-chain state, thereby architecting an overhead-reduced blockchain optimized for data availability. This setup excludes any enshrined on-chain smart contract environment for now. Anticipated network enhancements are directed towards preserving a minimal state machine, allowing rollups to validate Celestia’s canonical chain without the overheads of unrelated smart contract verifications, and concurrently reducing state bloat for both rollups and Celestia.

The elucidation of these values not only underscores the ethos driving Celestia but also fosters a conducive environment for user-centric and trust-minimized blockchain ecosystems.

Ethereum's Layer 2 Debate: Buterin Aligns with Daniel Wang on Validium Classification

Ethereum’s co-founder, Vitalik Buterin, has sparked a significant discussion in the crypto community regarding the classification and nature of layer 2 scaling solutions, especially focusing on the concept of validiums. This debate arises following Buterin’s agreement with a statement by Daniel Wang, the founder of the Ethereum rollup solution Taiko, on the classification of certain layer-2 solutions as validiums.

Buterin concurred with Wang’s view that Ethereum rollups utilizing external data chains, such as the modular blockchain Celestia, should be considered validiums rather than traditional rollups. The crux of this classification lies in the security guarantees provided by these solutions. Buterin emphasized that the essence of a rollup is its unconditional security guarantee, which allows users to recover their assets even in cases of collusion. This level of security is compromised when data availability relies on external systems, a characteristic of validium networks.

Validiums, a subset of Ethereum scaling solutions, use zero-knowledge proofs to facilitate off-chain transactions while depending on Ethereum’s mainnet for security and verification. Unlike zero-knowledge rollups that batch transactions on a layer-2 network and then verify them on Ethereum’s main chain, validiums do not post full transaction data to the main chain. Instead, they post cryptographic proofs of the transactions’ validity, aiming for greater scalability since the complete transaction data isn’t stored on-chain. However, this approach has its drawbacks, notably in terms of data availability, as it depends on operators to post honest proofs.

The debate around validiums and their classification as layer-2 solutions is not just technical but also conceptual. It reflects the evolving nature of Ethereum’s infrastructure and the diverse perspectives within its community. Buterin, in response to the debate, suggested new terminologies, proposing terms like “strong” for security-favoring systems and “light” for scale-favoring systems, such as validiums. This proposal is part of a broader conversation about the trade-offs between security, decentralization, and scalability in the development of Ethereum’s layer-2 solutions.

Despite the ongoing debates, the adoption of layer-2 networks like Arbitrum and Optimism is increasing, indicating a growing interest and investment in Ethereum’s scaling solutions. The upcoming Ethereum Merge upgrade is anticipated to further boost the efficiency and appeal of these networks.

In summary, Ethereum’s journey mirrors the early days of the internet, evolving from a niche technology to a mainstream platform. As Ethereum undergoes significant technical transitions, including the layer-2 scaling transition, it faces challenges similar to those the internet overcame. This evolution, marked by debates like the one sparked by Buterin, is a testament to Ethereum’s dynamic and innovative community, striving to balance scalability, security, and decentralization.
