Lit Protocol: Consumer-Friendly Public Key Infrastructure (PKI)

Lit Protocol is a web3 native key management service (KMS) revolutionizing public key infrastructure (PKI) through the use of multi-party computation (MPC) and trusted execution environments (TEEs). Through Lit, developers can create and control keys and run code for virtually any application that can be made private, immutable, and / or autonomous.   

Lit offers a suite of advanced features that include identity-based encryption, non-custodial crypto wallets that support “web2” native authentication (i.e. Passkeys), and programmable condition-based signing (IFTTT).  You can use Lit for things like decentralized access control, secure serverless signing, programmable keys for automated transactions and conditions, user-friendly authentication methods beyond traditional seed phrases, encrypted messaging, automated issuance of verifiable credentials, and enhanced data integrity and security. This breadth of capabilities positions Lit Protocol as a foundational technology for enabling a wide array of secure, decentralized applications and services across the web3 ecosystem. 

Decentralized ownership is enabled through state changes and signing. Lit Protocol aims to solve for the signing portion of this equation to a magnitude we haven’t seen before. We believe this positions Lit Protocol as the key to unlocking access to secure and customizable blockchain interactions. 

What is PKI? 

Public Key Infrastructure (PKI), a cornerstone of digital security, orchestrates the management of key pairs—public and private—that are essential for secure blockchain operations. These key pairs are not exclusive to cryptocurrency. They have been integral to internet security for decades and have a particularly crucial application within blockchain technology. PKI's primary aim is to ensure the secure electronic exchange of information across various online activities, including e-commerce, internet banking, and confidential communications. SSL/TLS (HTTPS) certificates used in Web2 for securing website connections offer a close analogy. A website’s SSL certificate includes a public key for the site, and the site’s owner holds a corresponding private key. When you connect to a website securely, the website proves its identity by using its private key to sign information that your browser verifies using the public key in the certificate. These certificates are issued by trusted Certificate Authorities, which remain highly centralized. Such mechanisms are fundamental to establishing secure, confidential, and authentic digital communications on the internet we all use daily. 

The Certificate Authorities’ role is a centralized and trusted one. Building on the foundational principles of PKI, Lit Protocol introduces a transformative approach by decentralizing the entire infrastructure, marking a significant evolution from the centralized models of traditional PKI systems. This decentralization addresses a critical vulnerability of the conventional system: its susceptibility to censorship and centralized points of failure. By distributing the management of public and private keys across a decentralized network, Lit Protocol not only enhances security but also imbues the system with inherent censorship resistance. This shift ensures that no single entity can control or compromise the integrity of the network, thereby safeguarding the privacy and security of digital interactions against various threats, including government interference or corporate overreach, while remaining compliant to the standards, such as KYC, that may be enforced by the entity that is using the Lit network. 

Furthermore, this decentralized model democratizes access to secure communication, allowing individuals and organizations to establish trust without relying on a centralized point of control. This is particularly revolutionary for decentralized applications (dApps), which thrive on autonomy and resistance to censorship. By embedding decentralized PKI directly into our digital world, Lit empowers developers to create applications with built-in security and identity verification mechanisms. This not only streamlines the development process but also significantly elevates the trustworthiness and resilience of applications within the ecosystem. Consequently, Lit Protocol is not just an enhancement of existing PKI standards but a pivotal innovation that addresses the core challenges of digital security and privacy in a decentralized world. 

What does Lit Protocol Enable? 

Lit Protocol's decentralized PKI framework seeks to unlock a myriad of compelling use cases, each designed to leverage the unique advantages of its secure, decentralized architecture. One of the most groundbreaking applications is in enabling secure access control for data. By utilizing Lit, developers can now conditionally render content based on the ownership or possession of specific NFTs or tokens, seamlessly integrating blockchain-based access criteria into web applications. This not only innovates the way content is gated but also introduces a new paradigm for digital rights and memberships, where access to exclusive content can be directly tied to blockchain assets. 

Another intriguing use case of the Lit Protocol is decentralized messaging. With its robust encryption standards, the protocol enables the sending of encrypted messages that can only be decrypted by those who meet the required on or off-chain conditions (e.g. token gating). This unlocks an ever changing base of token holders that can read messages depending on whether or not they hold the token at that point in time. This fosters a new level of privacy and security in communication, ensuring messages remain confidential and tamper-proof across decentralized networks, while allowing for dynamic membership. 

The Lit Protocol revolutionizes blockchain interaction with its advanced Programmable Key Pairs (PKPs), streamlining non-custodial user onboarding and enabling serverless signing. This innovation facilitates a variety of use cases: from automating transactions based on specific conditions—such as on-chain limit orders and recurring payments—to enabling seamless cross-chain messaging and asset swaps without centralized intermediaries. It simplifies user onboarding with seed-phrase-less methods and familiar Web2 authentication flows, enhancing accessibility for non-crypto natives. 

Moreover, the protocol supports the automated issuance of verifiable credentials and the generation of cryptographically verifiable signed data, crucial for enterprise applications and ensuring data integrity across the web. For account security, it introduces robust backup and recovery mechanisms, mitigating the risk of asset loss due to compromised keys. 

Why We Invested in Lit Protocol 

We invested in Lit Protocol because we believe the protocol provides significant improvements to the blockchain stack and pushes the blockchain ecosystem forward, a mission critical to our investment thesis. Lit protocol offers developers access to tools and infrastructure that allow them to build more novel, consumer-friendly applications that are secure, as well as reducing the technical lift that individual developer teams need to undertake to realize the full potential and promise of blockchain technology, namely privacy, programmability, and security. 

Following extensive testing across numerous iterations of testnet environments, the Lit Protocol has unveiled its V0 Habanero Mainnet Beta. We believe this significant milestone heralds the protocol's readiness for real-world application development, offering robust features such as ID encryption, user wallet integration, and serverless signing. The adoption and recognition of Lit Protocol's innovative solutions by leading research and development teams, including notable entities such as Fox Corporation, underscore the platform's relevance and potential impact on the tech landscape.
