Midnight Network Routes Zswap Offers Through Celestia, Ditching Traditional P2P Broadcast
Midnight Network has integrated Celestia's data availability layer as a direct substitute for the peer-to-peer gossip network its Zswap protocol uses to broadcast and discover trade offers, marking one of the first times a privacy-preserving swap protocol has replaced networking infrastructure with a verifiable data layer.
The integration, detailed in a Celestia blog post dated June 23, 2026, shifts how Midnight's Zswap users find counterparties. The primary Celestia blog post was not confirmed accessible at the time of research; the facts in this article are drawn from a summary provided to the Verse Press research desk. Verse Press contacted Midnight Network and Celestia for comment before publication; this article will be updated if responses are received.
Instead of broadcasting trade offers across an ephemeral peer-to-peer network where messages can be lost if nodes go offline, offers are now written to Celestia blobs (discrete packets of data posted to Celestia's network). Any participant can read from the Celestia data availability layer to discover and match open offers. The result is a persistent, verifiable broadcast channel that requires no bespoke gossip infrastructure.
What Zswap Does and Why Discovery Matters
Zswap is Midnight's zero-knowledge atomic swap protocol. It allows users to exchange multiple asset types privately, with transaction merging handled off-chain before final settlement on Midnight's chain. The protocol is based on Zerocash concepts: counterparties learn the minimum amount of information necessary to complete a trade, and the matching step requires minimal information disclosure, with selective disclosure controls governing what participants and observers can see.
The coordination step has always been the friction point. For a swap to happen, one party must post an offer and another must find it. Traditional approaches use gossip networks, where nodes pass messages to one another in a manner broadly analogous to peer-to-peer message propagation, though with different topology and trust assumptions than consumer file-sharing systems.
These networks are fast but unreliable. Messages are not stored, nodes drop in and out, and there is no way to verify that an offer was ever broadcast at all. Celestia solves this by acting as a shared, tamper-resistant posting board. Once an offer is written to a Celestia blob, it stays retrievable and verifiable for any participant.
Celestia's Broader Ambition Beyond Rollups
This integration is the second published case study of Celestia being used outside its core rollup data availability business. The first was OnchainDB, which built a pay-per-query micropayment database on Celestia Fibre, Celestia's high-throughput blockspace protocol announced in January 2026.
Fibre achieved 1 terabit per second across 498 nodes, running 881 times faster than KZG-based encoding protocols and hitting 1,500 times the throughput originally targeted in Celestia's roadmap. Blob sizes range from 256KB to 128MB. At that scale, Celestia is pitching itself not just as rollup plumbing but as general-purpose infrastructure for any market that needs persistent, high-volume data posting, including order books, AI agent payments, and commodity auctions.
That ambition is structured around a three-eras framework Celestia outlined at Fibre's launch: from 10KB per second (suited to AMM trading) through 1 to 10MB per second (enabling onchain order books) to 1GB per second and beyond, what the team calls "everything markets." The Midnight integration sits squarely within the logic of that third era, where data availability infrastructure serves as the substrate for any high-volume coordination market.
TIA, Celestia's token, was trading at $0.3967 at time of publication, up 10.1% over seven days, with a market cap of roughly $372.8 million and 24-hour volume of $51.5 million. The token saw a 13.76% price jump when Fibre launched in January. Token prices are point-in-time figures and will have changed since publication.
Midnight's Position in the Cardano Ecosystem
Midnight launched mainnet on March 30, 2026, as a partner chain to Cardano, built by Input Output Global (IOG). It uses ZK-SNARKs for transaction confidentiality and a dual-ledger architecture that separates public state from private state. Users can set disclosure to one of three levels: fully public, auditor-visible, or full access, where an authorized party such as the user or a regulator holding access keys can see complete transaction detail.
The protocol runs on a dual-token model, with NIGHT handling governance and DUST covering gas fees.
NIGHT was trading at $0.03247 at time of publication, with a market cap of approximately $538.9 million and a fully diluted valuation of $778.7 million. Daily trading volume was $7.19 million. As with TIA, these figures are point-in-time and subject to change.
IOG founder Charles Hoskinson announced the mainnet timeline in February 2026 alongside a set of launch partnerships. "We have some great collaborations to help us run it. Google is one of them. Telegram is another," he said at the time. The specific roles of Google and Telegram in those partnerships were not detailed in public disclosures available at time of publication.
Midnight's ecosystem has expanded further through a partnership with the COTI Foundation in 2026, aimed at broadening privacy infrastructure interoperability. A simulation platform called Midnight City, launched February 26, 2026, served as a pre-mainnet environment for proof generation stress-testing in the weeks before the March mainnet launch.
Why This Matters Outside North America
For developers and users in Sub-Saharan Africa and South Asia, the combination here carries practical weight. Sub-Saharan Africa is among the fastest-growing crypto regions globally by transaction volume, with activity up more than 50% year over year in 2025 according to Chainalysis, concentrated in transfers under $10,000.
Remittances, peer-to-peer commerce, and informal trade finance dominate the use pattern. Confidential atomic swaps designed for privacy without sacrificing verifiability fit that context directly.
South Africa's Capital Flow Management Regulations, effective in 2026, require 30-day declarations for crypto asset acquisitions and grant authorities the right to search devices for seed phrases. Non-compliance carries fines reaching ZAR 1 million or up to five years' imprisonment. Separately, CARF reporting requirements took effect March 1, 2026, adding further compliance obligations for crypto asset service providers operating in the country.
Midnight's selective disclosure model is relevant here: regulators can be granted auditor-level access to transaction data while counterparty identity and trade terms remain private. That architecture positions the protocol as a compliance tool rather than a circumvention one.
IOG has an active developer presence across Kenya, Ethiopia, and Nigeria through the 2026 African Blockchain Championship, targeting more than 120 developer trainees and 15 or more on-chain Cardano projects. That pipeline feeds directly into the Midnight ecosystem.
South Asia
South Asia presents a different but equally significant context. India's 30% flat tax on crypto gains, introduced in 2022 and still in effect as of mid-2026, has suppressed retail participation while doing little to deter institutional interest. No DeFi-specific regulatory framework exists across South Asia as of mid-2026, leaving projects like Midnight operating in a space defined more by tax treatment than by protocol-level rules.
IOG's Developer Experience Initiative is targeting 30% growth in developer onboarding across the region. For cost-sensitive markets where infrastructure expense often determines which protocols gain traction, Celestia's sub-cent-per-kilobyte data availability pricing is a meaningful enabler. A protocol that combines low-cost persistent broadcast with selective disclosure may find a more receptive audience in South Asia than privacy tools that offer no path to regulatory legibility.
What Comes Next
Celestia's Lotus mainnet upgrade, released in June 2026, adds cross-chain transfer capability and cuts annual token inflation by 33%. The timing with this case study publication appears, in this author's analysis, to reflect a deliberate effort to build out Celestia's non-rollup use case library alongside a broader market repositioning effort. No statement from Celestia confirms that framing directly.
For Midnight, the Celestia integration removes the overhead of maintaining a custom P2P layer and gives Zswap offer discovery the same verifiability guarantees that underpin the rest of the protocol.
More case studies in this direction would signal whether Celestia's "everything markets" framing is gaining traction beyond the modular rollup ecosystem where it built its initial 50% market share.
