Welcome to Chainletter

We’re on a Mission to Stop Liars

Our leadership team originally came together through a shared passion for bringing cutting edge technology to the publishing world, but soon discovered that our technology could be used to create a global network of truth…one that can protect businesses, organizations, and individuals from lying and fraud. Together, we have decades of experience as technology thought leaders and entrepreneurs.

Approximately one year ago, we wrote the Chainletter Labs foundational Whitepaper, laying out our vision for how digital technologies and Blockchain can be combined to create a new layer of trust to combat lying, fraud, and misinformation. Since then, we’ve changed some of our terminology (Postmarks are now Stamps) but the core vision remains.
