Interviews
Cardano Constitution and Governance #01
On November 21, 2024, Jack Briggs appeared on the Kaizen Crypto YouTube channel to discuss Cardano's governance framework and the activities of Intersect MBO. During the interview, Briggs stated that Intersect operates as a member-based organization within the Cardano ecosystem and is involved in governance-related initiatives and development coordination. He reported that the organization had more than 1,700 paid members and over 2,000 associates at the time of the interview.
Briggs discussed a series of constitutional workshops conducted in different regions to collect community feedback on Cardano's draft Constitution. According to his account, 63 workshops were held, and delegates selected through those events were expected to attend a constitutional convention in Argentina in December 2024. He stated that the convention would review the draft Constitution before its submission for on-chain ratification.
The interview also covered Cardano's governance implementation process. Briggs explained that the Chang upgrade introduced a governance bootstrapping phase, while a subsequent upgrade planned for December 2024 was intended to activate additional governance functions, including treasury-related actions and expanded voting mechanisms. He outlined the responsibilities of the Interim Constitutional Committee, Delegated Representatives (DReps), and Stake Pool Operators (SPOs) within the governance structure.
In addition, Briggs addressed proposals related to Cardano's 2025 budget process. He stated that discussions were underway regarding the allocation of treasury resources to categories such as infrastructure, research and development, education, community activities, and other ecosystem-related initiatives. Briggs also described participation options available to community members, including delegation, voting, and involvement in Intersect working groups.

Treasury Withdrawal Governance and Funding Framework #02
On July 21, 2025, Jack Briggs appeared on the Cardano Treasury Withdrawals LIVE | Intersect Jack Briggs Explains podcast hosted by Paul from the Cardano With Paul YouTube channel. During the interview, Briggs discussed Intersect’s involvement in the administration of Cardano treasury withdrawal proposals and the governance procedures associated with their approval.
Briggs described Intersect as a membership-based organization within the Cardano ecosystem that participates in governance-related activities, including coordination, strategic planning, and treasury administration. He stated that 39 treasury withdrawal proposals were submitted as individual governance actions following an earlier selection process in which 194 proposals were reviewed and reduced through community voting mechanisms.
According to Briggs, the treasury withdrawal process required separate on-chain approval for each proposal after the adoption of a broader budget action. He explained that approved withdrawals would transfer treasury funds to a smart contract framework developed in collaboration with Sunday Labs. The framework was designed to hold funds in dedicated contracts and distribute them according to predefined milestone schedules established for individual projects.
Briggs stated that the funding structure incorporated multisignature controls and included an external oversight committee composed of organizations within the Cardano ecosystem. According to his description, the committee participated in reviewing administrative actions related to fund allocation and contract management.
During the interview, Briggs outlined the use of milestone reporting procedures associated with funded projects. He stated that project deliverables, payment schedules, and contract modifications would be recorded through the funding framework and made available through public interfaces connected to on-chain data. He also discussed the treatment of treasury allocations denominated in ADA and referenced the use of stablecoins, including USDM and USDA, within certain funding arrangements.
The discussion also addressed governance participation requirements, voting thresholds for treasury withdrawals, and the administration of treasury funds after approval. Briggs stated that the process combined on-chain voting mechanisms, milestone-based fund distribution, and oversight procedures for projects receiving treasury allocations. [7]
