The Diem Association is a member-based association dedicated to building a blockchain-based payment system that supports financial innovation, inclusion, and integrity.
Diem Improvement Proposals (DIPs) offer the Diem developer community a way to participate in advancing the features and functioning of the Diem payment network (DPN), either by proposing a change or engaging in discussion about a proposal. Learn more about how DIPs work here. You can also view the current list of all DIPs.
The Technical Steering Committee (TSC) comprises members who supervise technical design and development of the Diem Blockchain.
Appointed by the Council, the TSC is comprised of representatives from Member organizations who are tasked with advising on the technical design and development of the Diem network.
