Olá pessoal!
Brazil’s Central Bank shook the market earlier this month by announcing that it remove the blockchain component of the Drex project (at least in the short term). The project will now pivot to focus on unlocking collateral via lien reconciliation using a non-blockchain solution.
The Drex project has been the driver of much of the blockchain activity in the country over the last couple years. So what does this pivot mean: is it a rug pull? or a moment for the private sector to take the lead and continue generating momentum?
To discuss, I am joined by Gustavo Cunha, CEO of Fintrender and a former Brazilian banking executive, and Marcos Sarres, CEO of GoLedger - a firm specializing in blockchain development on Hyperledger.
Both Gustavo and Marcos have been following the Drex project in different capacities since its initiation in 2021, and offer valuable perspective on why blockchain did not work out as planned for Drex (at least not yet), and the road ahead for blockchain in Brazil without Drex as the driving force.

Motives Behind the Pivot
The core reasons for pulling the plug on blockchain here are multi-faceted, but ultimately boiled down to technical constraints. Specifically:
Ethereum's inherent transparency conflicted with unique multi-bank privacy requirements. Banks in the Drex network required transaction isolation while maintaining Central Bank supervisory visibility
Privacy preserving technologies like zero-knowledge proofs and homomorphic encryption solutions have extended development timelines and are not yet ready for the scale of a project like Drex
Collaborative efforts by Microsoft, Parfin, and other major players to solve this problem ultimately proved too time-intensive
Gustavo notes that the pivot decision was also in part to some other factors:
The United States' movement toward regulated private stablecoins and away from centralized CBDCs
Leadership changes at the Central Bank (Drex champion Roberto Campos Neto is out as president)
The recent Pix security incident at the Central Bank, necessitating increased focus on cybersecurity
A Net Positive?
While the pivot decision may feel like a rug pull, Drex has advanced the blockchain and tokenization space in Brazil in many ways. Consider:
Major financial institutions developed internal blockchain teams (20-30 specialists each)
Multiple tokenization projects are now in development across carbon credits, loans, and collateral
The private sector gained substantial blockchain expertise through Drex participation
Market readiness for tokenized asset infrastructure significantly improved
Still, the vacuum created by the Central Bank's withdrawal presents both challenges and opportunities. Gustavo and Marcos suggest the most likely scenario involves private sector collaboration to develop blockchain infrastructure, potentially through banking associations like Febraban.
However, this approach faces coordination challenges, particularly around developing a Brazilian real stablecoin where competing banks must agree on float distribution, interoperability, governance and revenue-sharing models, etc.
I enjoyed this timely conversation with Gustavo and Marcos and I hope you do as well. You can connect with both of them on Linkedin.
