Two Blockchain Startups Aim to Kill the Captcha 1906

Two blockchain startups have good news for those tired of teaching AIs to recognize stops signs, announcing a new ethereum-based solution Wednesday that is aimed to tackle the current plague of automated bot nets on the internet.

Anyone who uses the web is aware at some level that bots are a problem – that’s why we have to spend so much time proving our humanity. Increasingly, accessing a site involves checking a box, or more annoyingly, picking out blurry images that include certain objects like traffic signals and bikes (though this has the added benefit of teaching self-driving cars not to run into things).

These captchas (short for “Completely Automated Public Turing test to tell Computers and Humans Apart”) are irksome from a user’s perspective, but the underlying problem is a severe headache for companies, who can never be sure how many impressions their ads are getting from humans, versus bots.

In order to solve this problem, Datawallet has announced a new product, the “Bot or Not protocol,” to cut down on the prevalence of bots on ad networks. The company has developed the product in partnership with another startup, Enigma, which focuses on keeping data private in blockchain-based smart contracts.

Portkey Announces Integration of Zero-Knowledge Proofs for Enhanced Identity Management and Security 6112

Portkey, the innovative account abstraction wallet on the aelf blockchain, proudly announces its latest initiative to enhance user security and privacy through the integration of Zero-Knowledge Proofs (ZKPs). This cryptographic technique allows one party (the prover) to prove to another party (the verifier) that a particular statement is true without revealing any additional information, ensuring unparalleled privacy and security for Portkey’s users.

The integration of Zero-Knowledge Proofs (ZKPs) in Portkey’s Web3 wallet and decentralised identity management system promises to offer blockchain users unprecedented levels of provable and tamper-proof identity verification. Portkey will enable users to securely prove their eligibility and compliance with service providers’ requirements without disclosing sensitive personal information. By ensuring digital personas are both distinct and verifiable, Portkey’s adoption of ZKPs aims to bridge the gap between Web2 and Web3 applications, fostering a more secure, privacy-centric, and user-focused internet.

As the prevalence of digital transactions and online interactions increases, it has become even more imperative to protect user data. Portkey’s upcoming integration of ZKPs significantly strengthens its security framework, ensuring that sensitive user information remains confidential and secure. This allows users to engage with digital services confidently, knowing their data is safeguarded by the highest standards of cryptographic security. Portkey’s commitment to privacy and security is a cornerstone of its mission, aimed at establishing a safe and trustworthy digital environment for users navigating the complexities of this increasingly interconnected world.

Introducing SocialLogin

Portkey intends to operate ZKPs through SocialLogin, which encompasses a two-step process: proof generation and verification, for secure transaction validation. In the proof generation phase, the prover creates a proof that confirms the validity of a statement using advanced cryptographic methods. During verification, this proof is evaluated by a verifier who, if the proof is valid, accepts the statement as true without accessing any underlying data. This integration will grant developers the capability to allow users to authenticate themselves on their preferred dApps through their pre-existing social accounts on platforms like Google, Facebook, Twitch, and various other third-party providers.

At the application level, users register with Portkey by logging in with Google credentials and receive an identity token (JWT). This token is sent to the Proving Service, which generates a zk-SNARK proof. The proof is then used to sign transactions on aelf blockchain, where it is verified on-chain. If the proof is valid, the transaction is executed, ensuring enhanced security and privacy for users. At the protocol level, this involves creating a new interface to generate proofs, developing verification functions, and converting proof-based transactions to normal ones while ensuring robust error handling and testing.

This technological advancement for Portkey is critical for enhancing users’ security and privacy as it eliminates the dependence on external verifier services, and solidifies its position as a pioneering force in the realm of digital wallets and decentralised identity management. SocialLogin is currently being developed and intergrated swiftly on Portkey. Soon, users will be able to experience the smooth login and registration process.

Horizen Labs Launches zkVerify – The Most Efficient Modular Blockchain for ZK Proof Verification 7458

Horizen Labs is proud to announce the official launch of zkVerify, a dedicated zero-knowledge proof verification network designed for settlement optimization.

The launch of zkVerify comes at a critical time when blockchain networks are increasingly seeking efficient and scalable solutions to meet the demands of high transaction volumes and complex operations.

In recent years, web3 developers have embraced modular solutions to optimize the core functions of blockchain protocols — execution, consensus, data availability, and settlement— as individual functions. Modular architectures propose a more efficient alternative to monolithic chains, which combine these features into one protocol. zkVerify is uniquely architected as the most efficient ZK modular solution for the settlement layer that collapses security costs by decoupling proof verification from settlement on L1s.

Horizen Labs estimates $47 million was spent on proof verification in 2023 for zk-rollups on Ethereum alone, and industry studies anticipate zk proof generation will become a $10 billion market by the year 2030. zkVerify removes the cost and complexity of computationally intensive proof verification for developers building with zk-rollups, proposing a critical unlock for the scalability and adoption of decentralized applications. At the outset, zkVerify can be used to verify proofs for Ethereum and Bitcoin L2s with a 91% cost reduction, and will rapidly expand to support multiple blockchain architectures. As zk-rollups continue to gain adoption as a critical scaling infrastructure, zkVerify is introducing a new standard of proof verification for zk-rollups of any kind on any settlement layer.

Key Features of zkVerify

  • Fast Modularized Process: Allows blockchain networks to offload the computationally heavy and expensive process of proof verification, enabling them to focus on their primary functionalities and stay ahead of their competition.
  • Cost-Effective Proof Verification: Reduces the cost of proof verification by up to 91%, a change that could have saved ZK Rollups over $42.8 million in 2023 alone.
  • Streamlined and Easy Integration: Seamlessly integrates with existing blockchain ecosystems and multiple SNARK proving schemes, minimizing technical overhead with a developer-friendly environment.

“The zkVerify platform is not just about reducing costs—it’s about enabling innovation and scalability in a way that wasn’t possible before,” said Rob Viglione, Co-founder and CEO of Horizen Labs, “by offloading proof verification, we allow developers to optimize settlement through a modular approach, unlocking more resources and value for both developers and users.”

zkVerify is Live on Testnet

Designed for seamless integration with existing blockchain networks, zkVerify minimizes technical overhead and provides a developer-friendly environment for proof verification across a wide range of zk-rollups and settlement layers. Built by Horizen Labs, the development studio behind the EVM-compatible Horizen network, zkVerify can also be used by builders within the Horizen ecosystem. Leading zk and web3 projects like Gevulot, Caldera, and will be some of the earliest networks using zkVerify for proof verification.

zkVerify is now live on testnet and can be accessed through Web3 developers are invited to explore how zkVerify can enhance their operations and contribute to the scalability of their projects.
