About

ProofSign is an electronic-signature and document-verification platform for individuals, professionals, teams and organizations signing finished PDFs. Users upload documents, invite signers and approvers, and run single- or multi-party workflows. Participants verify email access with a one-time passcode. ProofSign records signing intent, participant actions and timestamps in an audit trail. Completed PDFs include a SHA-256 fingerprint and evidence recipients can check through a public verifier without an account. The service supports agreements and finalized documents that need an auditable signing record and a way to detect later file changes. Its free plan allows single-party signing and verification for up to 10 documents monthly under fair use. Users can earn credits through onboarding and signing milestones. The Pro plan includes a verification API.

About

World ID is a privacy-preserving protocol that lets people prove facts about themselves online without sharing unrelated personal information. The World ID app lets users claim, manage, and present cryptographic proofs, including Proof of Human, Proof of Presence, and Proof of Attributes such as age or nationality. Proof of Human is obtained through Orb verification, while other proofs can be claimed through supported verification methods. People use World ID with participating apps and services for human verification and access checks. Developers can integrate World ID into web, mobile, and decentralized applications to help limit bots and duplicate accounts and verify human participation. The protocol is open source, and available proofs, integrations, and verification methods vary by location and implementation.
