Decentralized identity systems allow users to gather and amnage their own credentials under the banner of self-created decentralized identifiers (DIDs). The key focus of DIDs is on shifting the control of a credential into users' hands. Existing decentralized identity proposals, however, suffer from several problems. First and foremost, how do you bootstrap an ecosystem of credential issuers? It is unlikely that most existing legacy providers suddenly switch and issue such credentials. Second, like with cryptocurrencies, DID systems burden users with managing their own keys creating a significant risk of key loss. They also omit essential functionality, like resistance to Sybil attacks and the ability to detect misbehaving or sanctioned users. We address these problems by introducing CanDID in our new paper.

We have focused on building a non-custodial relayer, Infura Transaction Service (ITX), that takes a pre-signed message (e.g. meta-transaction), packs it into an Ethereum transaction and then gradually bumps the fee until it is mined in the blockchain.

Flashbots is a research and development organization formed to mitigate the negative externalities and existential risks posed by miner-extractable value (MEV) to smart-contract blockchains. We propose a permissionless, transparent, and fair ecosystem for MEV extraction to reinforce the Ethereum ideals.

Many central banks are considering, and some are even piloting, central bank digital currency. This column provides an overview of important considerations for central bank digital currency design. While central banks already provide wholesale digital currency to financial institutions, a retail central bank digital currency would expand access to more users and provide opportunities for innovative central banking. The design must balance these benefits with the potential risks created by retail central bank currency deployment.

In this paper, we enumerate the fundamental technical design challenges facing CBDC designers, with a particular focus on performance, privacy, and security. Through a survey of relevant academic and industry research and deployed systems, we discuss the state of the art in technologies that can address the challenges involved in successful CBDC deployment. We also present a vision of the rich range of functionalities and use cases that a well-designed CBDC platform could ultimately offer users.

DECO

DECO is a privacy-preserving oracle protocol. Using cryptographic techniques, it lets users prove facts about their web (TLS) sessions to oracles while hiding privcy-sensitive data. For further details, please check out the Projects Page.
