Charles Hoskinson, founder of Cardano and Midnight and an early Ethereum co-founder, highlighted the connection between blockchain privacy and digital identity during a United Nations-related appearance. His remarks focused on how these technologies could alter interactions between individuals and governing institutions.

Verifications are typically time-consuming and ask users for more information than is needed for a particular transaction. Blockchain-based systems, however, could look to selective disclosure, whereby users would need to prove certain credentials without revealing the entirety of an identity record.
This method can be used in financial services, online platforms, government systems, and decentralized applications, to name a few. These challenges are being addressed in various ways by different blockchain networks, however.
Aster is a decentralized perpetual trading platform where privacy features are built into its trading system. It has some mechanisms documented that restrict public disclosure of some trading information.
The project is mainly linked to ‘decentralized derivatives’ and not to ‘digital identity’. However, its emphasis on transaction privacy puts it in the greater context of what information should be accessible to anyone on the blockchain.
Arbitrum is a Layer 2 chain built on top of Ethereum that is able to process transactions off-chain with compatibility with the Ethereum ecosystem. The network is able to run smart contracts and decentralised applications on various applications.
It is not marked for an identity focus but for its relevance to the identity discussion. With the proliferation of identity and privacy apps, Layer 2 solutions like Arbitrum can offer spaces for these apps to run at higher transaction speeds.
Aptos is a blockchain layer 1 designed to enable decentralized applications and digital assets using its network infrastructure. It spans various sectors such as decentralized finance (DeFi), gaming, and beyond, providing a diverse range of blockchain applications.
The network is thus yet another infrastructure layer that can be used to support future identity applications. Scalability is a crucial concern for systems that will be used by many users and many verification requests, as blockchain adoption grows.
Litecoin is not in the same class as the other assets in this group. It's traditionally been about P2P payments, not P2P identity or privacy apps.
It's included because of the broader spectrum of blockchain infrastructure that comes with the digital ownership and access to finance conversation. While blockchain technology continues to evolve beyond trading, payment networks are playing a crucial role in the overall digital asset landscape.
Polkadot has created the infrastructure to support interoperability, enabling various blockchain networks to connect within its system. It also has a range of ecosystem tools and proof-of-personhood initiatives.
These systems can enable verification without revealing too much personal information in the process. That's why Polkadot is of particular interest for the decentralized identity debate, but it has much more to offer than just identity services.
Hoskinson's comments to the UN have brought an issue back to the forefront, one that goes beyond cryptocurrencies. Going forward, this marriage of privacy, identity and blockchain infrastructure may be a growing necessity for digital services as they require more forms of verification.
Aster, Arbitrum, Aptos, Litecoin and Polkadot go about the wider blockchain market in a different way. They are not the same identity technology or the same goals, nor are they all part of the same ecosystem; they are all infrastructure around which other facets of privacy, verification, payments, interoperability are being built.
