The blockchain ecosystem faces a critical inflection point on March 25, 2024, as enterprise adoption accelerates while infrastructure challenges expose growing pains in Layer 2 scaling solutions. Two developments underscore this tension: Polygon’s zkEVM network recovering from a major sequencer outage, and the Hyperledger Foundation welcoming banking giants Citi and the Brazilian Development Bank as new members.
TL;DR
- Polygon zkEVM suffered a 10+ hour outage caused by a sequencer failure triggered by a Layer 1 chain reorganization
- The Hyperledger Foundation added Citi and BNDES as members and launched a Financial Services Working Group chaired by DTCC
- Over 40% of 92 surveyed financial firms cite Hyperledger Besu as their preferred enterprise blockchain protocol
- BRICS nations are planning a blockchain-based payment system using digital currencies
- Enterprise blockchain adoption continues to grow even as public chain infrastructure faces reliability tests
Polygon zkEVM Outage Exposes Layer 2 Growing Pains
Polygon’s zero-knowledge Ethereum Virtual Machine chain experienced a significant outage lasting more than 10 hours beginning on March 23, 2024. Data from Polygon’s block explorer confirms a gap of approximately 10 hours between consecutive blocks being sequenced and added to the chain. The Polygon core team attributed the issue to a problem with the blockchain’s sequencer, which was triggered by a Layer 1 chain reorganization on Ethereum.
The sequencer plays a critical role in Polygon zkEVM’s architecture, organizing and relaying transaction batches to the zkEVM smart contract deployed on the Ethereum mainnet. When the Layer 1 reorg disrupted this process, the sequencer failed to properly order and submit batches, effectively halting the entire rollup chain. The incident is particularly notable because Polygon zkEVM has been operating in its beta phase since launch, and extended outages raise questions about the reliability of zero-knowledge rollup technology for production workloads.
Polygon’s team confirmed the outage through an official post on X (formerly Twitter) on March 23, assuring users that the issue was confined to the rollup chain and did not affect other Polygon products. The core development team worked through the weekend to restore service, eventually bringing the network back online. A detailed post-mortem timeline shows the total network downtime extended to approximately 14 hours as engineers diagnosed and resolved the underlying issue.
Hyperledger Foundation Expands With Banking Heavyweights
While public blockchain infrastructure grappled with reliability issues, the enterprise blockchain sector celebrated a significant milestone. On March 19, 2024, the Hyperledger Foundation announced that global banking giant Citi and the Brazilian Development Bank (BNDES) have joined as new members. The foundation also unveiled a new Hyperledger Besu Financial Services Working Group, chaired by the Depository Trust and Clearing Corporation (DTCC).
The working group represents an industry-wide collaboration where enterprise users and code contributors can actively define new features and enhancements for Hyperledger Besu, a Java-based Ethereum client designed for both public and private permissioned networks. The founding members include some of the largest names in finance and technology: Accenture, Banco Central do Brasil, Consensys, Citi, Japan Securities Clearing Corporation (JSCC), Kaleido, LACNET, Mastercard, Santander, and Visa.
A recent analysis by Blockdaemon of the global tokenization ecosystem found that Hyperledger Besu is the most frequently mentioned protocol among 92 surveyed firms, which include banks, asset managers, and clearing houses. More than 40 percent of respondents cited Hyperledger Besu as their protocol of choice, signaling that enterprise Ethereum adoption through permissioned networks continues to outpace public chain adoption for institutional use cases.
Carlos Vivas, Senior Principal Engineer and Director at DTCC and chair of the new working group, emphasized the rapid growth of enterprise Besu adoption in the digital assets space. He noted that the initiative aims to support the financial services industry and help shape the future of financial markets through collaborative development.
BRICS Nations Push For Blockchain-Based Financial Infrastructure
Adding to the momentum of institutional blockchain adoption, the BRICS coalition — comprising Brazil, Russia, India, China, and South Africa — continues to advance plans for an independent blockchain-based payment system incorporating digital currencies. The initiative, which gained formal attention in early March 2024, represents a significant geopolitical shift in how major economies approach cross-border payments and financial sovereignty.
The proposed system would leverage distributed ledger technology to create a payment network independent of traditional Western financial infrastructure such as SWIFT. While details remain under development, the project underscores the growing recognition among sovereign nations that blockchain technology offers viable alternatives to legacy financial rails.
Contrasting Trajectories For Public And Enterprise Chains
The events of March 25, 2024 highlight a fundamental divergence in blockchain technology trajectories. Public Layer 2 networks like Polygon zkEVM are pushing the boundaries of scalability through cutting-edge zero-knowledge proofs, but they face reliability challenges that come with operating experimental technology at scale. Enterprise blockchain platforms, by contrast, prioritize stability and permissioned access, trading decentralization for operational certainty.
Bitcoin trades at approximately $69,958 on this date, with Ethereum at $3,590, reflecting a market that remains fundamentally optimistic about blockchain technology despite short-term infrastructure hiccups. The simultaneous expansion of Hyperledger’s enterprise membership and the ongoing challenges faced by public rollup networks suggest that 2024 will be defined less by competition between these approaches and more by their coexistence in serving fundamentally different market needs.
Why This Matters
The parallel developments in enterprise blockchain adoption and public chain infrastructure challenges illustrate that the blockchain ecosystem is maturing on multiple fronts simultaneously. The Hyperledger Foundation’s ability to attract major banks and financial institutions demonstrates that blockchain technology has moved well beyond the speculative phase into genuine institutional infrastructure. Meanwhile, the Polygon zkEVM outage serves as a reminder that cutting-edge scaling solutions still face significant engineering hurdles before they can match the reliability expected by enterprise users. For investors, developers, and institutions watching this space, the message is clear: blockchain adoption is not a single trajectory but a multi-lane highway where different solutions serve different needs at different stages of maturity.

10 hours of downtime on a sequencer and they still call it beta. thats not beta, thats production with an excuse label
a layer 1 reorg shouldnt be able to take down an entire L2 for half a day. what happens during actual network congestion?
The Hyperledger Besu stat is interesting. 40% of 92 financial firms choosing Besu tells you where enterprise blockchain actually lives, and its not on public chains
Citi and BNDES joining Hyperledger the same week Polygon fumbles its zkEVM. The contrast could not be sharper tbh
