Linda: Cardano’s Early Design Choices Are Now Appearing Across Rival Blockchain Roadmaps

Cardano’s research-first development model was frequently criticized for being too slow and academic. In a new analysis, Linda argues that competing networks are now adding the same technical priorities Cardano adopted years earlier, including formal verification, UTXO-based architecture, programmable privacy, token distribution and provably secure Proof of Stake.

Formal Verification and UTXO Return to Blockchain Roadmaps

Cardano’s development model is based on mathematically specifying, analyzing and testing protocols before deploying them on the network.

That process affected Cardano’s ability to match the pace at which competing blockchains introduced smart contracts, bridges and decentralized finance products. However, it was designed to eliminate entire categories of technical vulnerabilities before users’ funds were exposed.

The analysis connects that approach with more than $2.5 billion lost through blockchain bridge exploits over the past five years. Other examples include a critical Zcash vulnerability identified with the assistance of artificial intelligence and a remotely exploitable issue discovered in Ethereum validator software.

Ethereum has expanded its work on formally verifying cryptographic components and protocol infrastructure. Linda presents the development as a move toward the same principle that has guided Cardano, proving that critical systems behave as intended before they reach production.

Ethereum researchers are also exploring UTXO-based methods for storing and processing parts of the network’s state.

Cardano uses the extended unspent transaction output model, commonly known as eUTXO. The architecture allows individual transaction outputs to carry the data and execution conditions required by smart contracts.

Funds, spending rules and application states are therefore connected to explicitly defined outputs. The model differs from Ethereum’s global account-based state and was also central to the previous Cardano News report on Ethereum’s consideration of UTXO architecture for future protocol development

Midnight Brings Selective Privacy to Cardano

Privacy represents another area in which competing blockchain roadmaps are moving closer to Cardano’s direction.

Midnight is a Cardano partner chain designed for applications that need to protect sensitive information while still allowing specific claims to be verified. Developers can use its zero-knowledge technology and selective disclosure features to build applications that prove identity, access rights, compliance or financial information without publishing the complete underlying dataset on a public blockchain.

The network’s public value layer uses $NIGHT, while DUST provides the resource required to execute transactions and smart contracts.

Midnight launched its mainnet in March 2026 with an initial group of federated node operators. Confirmed participants include Google Cloud, Pairpoint by Vodafone, MoneyGram, Blockdaemon and eToro. The Midnight Foundation described the structure as an interim operational phase before the network transitions toward broader decentralized block production.

Comparable privacy initiatives are now appearing across other ecosystems. The examples presented include Ethereum’s expanded privacy team and wallet privacy tools, confidential token capabilities planned for the XRP Ledger and confidential transfers under development on Sui.

Stablecoin issuers and payment infrastructure providers are also examining cryptographic proofs that can protect transaction data while preserving the information required for audits and regulatory compliance.

This model differs from fully anonymous transaction systems. It combines data protection with controlled disclosure to regulators, auditors or authorized participants.

Midnight was designed around that balance from the beginning. In this context, $NIGHT serves as part of an application platform for organizations that need to protect private data and demonstrate compliance within the same system.

ADA Distribution and Ouroboros Complete the Cardano Comparison

ADA’s original distribution adds an economic dimension to Linda’s broader argument.

Cardano conducted a public voucher sale beginning in 2015 without a traditional venture capital funding round. The structure contrasts with projects where large portions of the token supply were sold privately to investment funds and early participants at substantially lower valuations.

The official Cardano genesis distribution records 25.93 billion ADA distributed through the public sale. Another 5.19 billion ADA, equivalent to 20% of the amount sold during the distribution, was allocated to IOHK, EMURGO and the Cardano Foundation.

Figures cited in the analysis estimate that approximately $97 billion in tokens entered circulation through unlock schedules during 2025, including about $19 billion allocated to insiders, venture capital investors and project teams. Solana is presented as an example of a network that raised approximately $314 million from private investors during its early development.

Linda also references reports that a Solana co-founder had acknowledged the advantages of combining public funding with staking. She notes that the original post could not be located, leaving the statement unconfirmed.

Hyperliquid provides a more recent comparison. Its team funded the platform’s early development and distributed 31% of the HYPE supply to the community through an airdrop.

Ouroboros completes the technical side of the comparison. Cardano’s Proof of Stake protocol family was developed through academic research, peer review and formal security proofs. Cardano launched in 2017 with Proof of Stake at a time when the security of such systems remained a major subject of industry debate.

Ethereum spent several years preparing its own transition. The Merge replaced Ethereum’s Proof of Work consensus with Proof of Stake in September 2022.

Formal verification, eUTXO architecture, selective privacy, public token distribution and provably secure Proof of Stake now appear across multiple blockchain development agendas. Linda’s position is that Cardano adopted these priorities before they became widely accepted and deserves greater recognition for the technical and economic decisions embedded in its original design.
