Event description



BCH DEVCON is a series of global hackathons taking place around the world and hosted by Permissionless Ventures and co-hosted by SV INSIGHT. Permissionless Venture is a venture capital firm that backs blockchain technology and bold entrepreneurs enabling a permissionless and decentralized world. We have built a global network of engineers, entrepreneurs, investors, industry experts executives, and other influencers in the blockchain ecosystem. We are committed to connecting these diversified minds in order to empower the permissionless world.

During the San Francisco Blockchain Week (SFBW), BCH DEVCON is making its debut to the public and the BCH community from October 10th to October 11th, 2018. BCH community is one of the most active communities in the Blockchain industry, not only famous for its endless “debates” with other communities (even among themselves) but a very active platform for developers. Some KOLs/hackers/geeks/believers are undertaking Satoshi’s vision- making a secure and capable money system without intermediaries.

BCH is now striving to get more developers onboard, educate more people about its vision and technology, and eventually have more people using BCH as a global money and beyond.

We will find 120 best Hackers to start this amazing 24 hours adventure journey. Take a look, and enjoy!
