[Opening Line, Inc.](https://www.opening-line.co.jp)in collaboration with the [Blockchain Collaborative Consortium](https://bccc.global) (hereinafter referred to as BCCC), has announced that it will use the blockchain-based stamp collection rally service "Peace Collection" at the Blockchain EXPO to be held at Makuhari Messe from 20 to 22 November 2024 (Wednesday to Friday).

## About the "Peace Collection"
This is a new type of stamp collecting rally where participants collect different experiences as 'pieces' (stamps) to complete a collection. In this system, pieces are shared across multiple collections, connecting them across regions, companies, past and future, real and virtual.
Proof of collection is issued as a "SoulBound token" (SBT). This makes it easy for anyone, anywhere to prove ownership and link to different systems.
