Enhancing accessibility in the world of cryptocurrencies and Web3: Worldcoin’s (WLD) latest state bridge integrated with World ID.
Web3, the decentralized future of the Internet, is rapidly evolving, offering numerous advantages and opportunities. However, persistent challenges exist in terms of accessibility and integration.
Worldcoin, a pioneering global identity protocol, recently took a significant stride to confront these challenges by introducing a new State Bridge.
This advancement paves the way for developers to seamlessly incorporate their solutions with the World ID protocol and EVM-compatible blockchains, fundamentally transforming the landscape of Web3.
In the domain of blockchain technology, state bridges serve as vital mechanisms to enable interoperability among diverse blockchains. They facilitate the smooth exchange of data between chains, breaking down barriers that can impede the growth of the Web3 ecosystem.
For Worldcoin, state bridges play a crucial role in sharing the current state of World ID contracts with other chains. This empowers developers to harness the potential of proof of personhood in Layer 2 solutions, sidechains, and beyond.
The World ID protocol and its Merkle tree framework
At the core of Worldcoin’s innovation lies the World ID protocol, embodied as a Merkle tree on the Ethereum blockchain. Within this structure, each leaf of the tree represents a distinct identity.
The Merkle tree’s root assumes a pivotal role in the creation and verification of zero-knowledge proofs (ZK proofs). These proofs serve as the cornerstone of a privacy-preserving identity framework with applications spanning a wide array of use cases.
To illustrate, Worldcoin’s WLD grants are solicited on Optimism through the World App, a mobile application compatible with World ID. Upon downloading the World App, a new secure wallet is established and deployed on the Optimism network.
Qualified grants can be acquired by generating a Zero-Knowledge Proof (ZKP), which undergoes verification when the “claim()” function of the RecurringGrantDrop contract is invoked on Optimism.
State Bridges facilitate the seamless transmission of the latest Merkle root to Optimism, ensuring that OpWorldID can validate proofs without any hindrance.
The progression of the state bridge design
Previously, Worldcoin’s State Bridge architecture had certain limitations. It had a close association with the WorldIdIdentityManager and required authorized access to initiate root propagation. Moreover, it propagated roots to all supported chains whenever new identities were added, resulting in gas inefficiencies.
The updated state bridge architecture introduces a modular, permissionless, and gas-efficient design.
Now, root propagation is detached from identity insertion, enabling more efficient addition of new identities. This separation has made state bridge propagation accessible to all, allowing anyone to propagate roots without restrictions.
Individual state bridges are also segregated, facilitating more frequent root propagation on specific chains as required.
This architectural shift empowers developers to deploy their state bridges for chains not yet supported by Worldcoin, enabling testing on any EVM-compatible chain.
With the updated state bridge architecture, World ID can be linked to any EVM-compatible chain. Several methods, including Optimism’s CrossDomainMessenger, Scroll’s ScrollMessenger, and Arbitrum’s Inbox, facilitate communication between layer 1 and layer 2.
Another approach involves leveraging storage evidence, particularly storage proofs, utilizing protocols like Axiom and Herodotus.
The target chain must be EVM-compatible and support EVM Pairing (ECC) and keccak256 precompiled functions.
To deploy state bridge contracts on both Layer 1 and Layer 2, a program is needed to periodically call the “propagateRoot()” function, sending the latest root to the receiver contract on the destination chain.
Additionally, the ability to retrieve inclusion proofs is crucial for creating Semaphore proofs that will be validated within the Layer 2 contract.
Worldcoin is actively developing tools, including a state-bridge-service and a tree-availability-service, to support root bridging and the generation of inclusion proofs for any EVM-compatible chain.
These tools are expected to be released in the coming weeks, further enhancing accessibility within the realm of Web3.
Evaluation of security and dedication to excellence.
The security and quality of updates pertaining to the protocol are of utmost significance. Worldcoin and its partners maintain a strong collaboration with auditing firms to guarantee the strength of their protocol releases.
Collaborations with audit companies like Least Authority and Nethermind play a pivotal role in evaluating both the off-chain and on-chain aspects of the protocol. This encompasses an examination of blockchain usage, cryptographic elements, and smart contract technologies. These measures are undertaken with the primary objective of upholding the protocol’s integrity and safeguarding users’ assets.
In summary: Web3, cryptocurrencies, Worldcoin, and the World ID protocol.
Worldcoin’s recent introduction of a state bridge represents a major leap in enhancing the accessibility and integration of Web3 solutions. This move empowers developers to establish their own state bridges, actively contributing to the broader Web3 ecosystem.
The ever-evolving Web3 environment is rapidly growing in inclusivity and connectivity, and state bridges play a pivotal role as gateways to a decentralized future.
