About
Radim Motycka is the founder and lead engineer of ProofSnap, a forensic web capture platform used to preserve web pages as evidence for disputes, investigations and brand protection work. He has worked on cryptographic protocols for more than ten years.

At ProofSnap he designs the evidence package. Each capture records the page as a screenshot, HTML and text, together with the DNS records, the domain registration data and the HTTP headers at the same moment, network-verified time and a chain of custody log. The package is sealed with SHA-256 hashes and a signed manifest, anchored on the Bitcoin blockchain through OpenTimestamps and, where required, stamped with an RFC 3161 qualified timestamp from a provider on the EU Trusted List.

ProofSnap works in four ways. A Chrome and Edge extension captures what the user sees in their own browser. A web dashboard, available in 29 languages, captures one URL or a batch, runs scheduled captures and change monitoring, compares two captures, and keeps captures in case workspaces with a chain of custody and exhibit export. A REST API with signed webhooks brings the same capabilities into brand protection and legal workflows. An MCP server lets AI assistants such as Claude, ChatGPT and GitHub Copilot capture, verify and compare web evidence from a chat.

His design rule is that whoever receives the evidence should not have to trust the vendor that produced it: every package can be checked with open tools and public data.

He writes about website evidence in UDRP and brand protection cases, independent verification of web captures, and the credibility of screenshots now that images are easy to fake.
