The first week of June 2026 became a period of serious trials for the Cardano ecosystem. The community rejected funding for the flagship Cardano Summit 2026 conference, the major analytics service TapTools announced its closure, and ADA token quotes dropped below $0.20 for the first time since 2020. Against the backdrop of these events, the community once again began to talk about a crisis of the project.

In a new piece, ForkLog tried to examine the situation and prospects of the blockchain platform, taking into account new details shared with the editorial team by a former IOG employee — the company that develops the Cardano protocol — and now a professor at the Department of Cybersecurity of the Institute of Computer Science and Artificial Intelligence at V. N. Karazin KhNU, Roman Oliynykov.

Everything against growth

The cancellation of the flagship Cardano Summit 2026 in Singapore became the first serious test for the new decentralized governance system of the Voltaire era. The Cardano Foundation (CF) nonprofit requested 7.8 million ADA from the treasury (about $1.3 million on the Binance exchange at the time of writing) to hold the main event of the year, and the majority of dRep delegates supported the initiative. However, the proposal fell short by 1.46% of the vote.

The foundation itself abstained from voting for the sake of impartiality, and the public appeals of Cardano co-founder Charles Hoskinson and CF CEO Frederik Gregaard failed to influence the outcome. Instead of a full-fledged summit, the ecosystem will be limited to a booth from EMURGO's commercial division at the TOKEN2049 conference.

This precedent clearly proved to the industry that in the updated Cardano network, authorities no longer play a decisive role — now everything is determined by the DAO and the treasury balance. 

However, the first serious transformation in the Cardano community went almost unnoticed by the media.

Roman Oliynykov believes that funding problems began to manifest much earlier:

"My main tasks were related to research at Project Catalyst, and in late 2025 — early 2026 the project at IOG was closed. Employees engaged in research and development engineers were laid off, and the team handling operational support of previous funds was transferred to the Cardano Foundation."

Oliynykov assumes that it was about optimizing IOG's operations, accompanied by the reduction of individual teams and research areas. At the same time, the expert did not find any obvious changes in the management process. According to him, all of this was preceded by the usual annual reports and budgeting procedures for the next period, as before.

Not long ago, the ecosystem lost two popular platforms. On May 23, 2025, JPG.store closed — Cardano's largest NFT marketplace, which had dominated the market for more than three years. On June 3, 2026, TapTools announced it was winding down operations — one of the main analytics services for more than a million users. The reason was a staffing collapse: in a short period, both co-founders, the COO and CTO, as well as a backend developer who was temporarily acting as CTO, left the team. There was no one left to maintain the infrastructure.

Charles Hoskinson reacted to the closure of TapTools with a post on X:

"I'm taking a break. We'll talk later."

Returning to the public arena, he admitted that he had previously proposed creating a treasury "index" to support troubled ecosystem startups, but the idea was never implemented. Hoskinson added that the second half of 2026 could bring a "wave of bankruptcies" and the consolidation of small protocols.

The quotes reacted predictably. According to TradingView, on June 4 ADA broke through the psychological level of $0.20 for the first time in more than five years. Between June 6 and 10, the asset tested the $0.148–0.162 marks. The decline from the all-time high of 2021 ($3.09) exceeded 93%.

According to DeFiLlama, at the time of writing the total value locked (TVL) in the network had dropped by more than a third over the month, to $93 million.

The main question for the industry remains the nature of current events: are they the growing pains of real decentralization or a sign of an ecosystem crisis.

The price of decentralization

According to the Cardano Foundation's report, as of the end of 2025 the organization had 287.5 million Swiss francs (about $361 million) on its balance sheet. Over the year, the foundation diversified its reserves: ADA's share of the portfolio fell to 51.6%, bitcoin holdings grew to 25.5%, and the volume of fiat funds reached 22.9%.

Despite the availability of funds, the decline in the ADA rate strongly affected CF's long-term planning, which accordingly triggered a cascading effect of cuts across all sectors.

IOG developers had to reduce the financial burden on the ecosystem: for 2026 they requested $46.8 million from the community, half the previous year's figure.

In parallel with the transfer of powers to dRep delegates, the work of Project Catalyst — the ecosystem's main grant mechanism — slowed down. Management of the program passed from IOG to the Cardano Foundation, after which the Fund15 and Fund16 rounds were cancelled, and the reserved liquidity was returned to the general pool until the introduction of a stricter payout model tied to KPIs.

Infrastructure projects whose business models relied on the expectation of regular tranches faced a funding shortage. In the absence of venture support and stable revenue, some startups were unable to survive this pause. The closure of TapTools and JPG.store was not so much a direct consequence of a lack of treasury funds as the result of a transition to stricter financial discipline. Under the new conditions, the DAO refuses to subsidize unprofitable projects amid macroeconomic pressure on the industry.

Academic isolation

The halt in grant funding would not have been critical if projects could compensate for the shortage of funds with external venture capital. However, here development runs up against Cardano's technological foundation. While the industry standardized around EVM and second-layer (L2) solutions, the IOG team initially bet on an alternative architecture — the Extended Unspent Transaction Output (eUTXO).

From a technical point of view, the eUTXO model provides a high degree of security: native tokens operate at the base layer of the blockchain rather than inside smart contracts. This minimizes the risks of logical vulnerabilities characteristic of networks like Ethereum or Solana. 

In Oliynykov's opinion, the competition definitely made sense in terms of the properties of consensus protocols. If you evaluate them by the level of decentralization and security guarantees, the Ouroboros family is head and shoulders ahead:

"During the development of consensus protocols for Cardano, truly advanced and unique scientific results were obtained that laid a new direction in the field of research on decentralized systems."

To understand the difference, Oliynykov provided a precise comparison of the mechanics of the Ethereum and Cardano blockchains.

Partition Tolerance:

• Cardano. Uses the longest chain rule. The protocol remains operational even when the P2P network splits into subnets (for example, in the event of connectivity failures between continents);
• Ethereum. Relies on BFT finalization. A network split causes failures in consensus operation and exposes honest nodes that find themselves in the minority or offline to risks.

Adaptive Security model:

• Cardano. Has rigorous security proofs under conditions where an attacker can dynamically bribe any consensus participants within their quota (<50% of stake);
• Ethereum. Consensus protocols have no proofs of cryptographic strength under this threat model.

Built-in protection against Long-Range Attacks:

• Cardano. The vulnerability is closed at the level of the fundamental protocol (Ouroboros Genesis). Additionally, Key Evolving Signatures are used: even a complete theft of a node's current private keys will not allow a hacker to generate valid blocks for past epochs;
• Ethereum. Such protocol-level mechanisms are absent; protection is implemented solely by external engineering methods (checkpoints / weak subjectivity).

Staking economics and the level of decentralization:

• Cardano. Liquid staking. There is no locking of funds, no minimum entry threshold and no penalties (slashing). This maximizes the share of coin participation in consensus, making an attack prohibitively expensive;
• Ethereum. Requires huge starting capital, lengthy locking of funds and carries the risk of penalties. Mass delegation is implemented through third-party smart contracts, which transfers the risks of vulnerabilities in contract code and the virtual machine directly to the blockchain's security level.

Academic rigor and formal proofs:

• Cardano. Based on transparent logic with mathematically rigorous proofs of cryptographic strength. Each protocol in the Ouroboros family underwent peer-review at leading global cryptographic conferences;
• Ethereum. The level of formal mathematical proofs and academic verification of consensus protocols is incomparably lower.

Later, engineers of the Polkadot and Mina Protocol blockchain projects took advantage of the breakthrough in Cardano's architecture. In turn, Ethereum successfully switched to PoS, using a structure of epochs and slots (Gasper) similar to Cardano, which confirmed the viability of such a time model for the largest networks.

However, for DeFi this mathematical rigor turned into structural isolation. The entry threshold for developers remained high. It is impossible to take auditor-verified code of a lending protocol in Solidity and quickly launch a similar dapp on Cardano. Smart contracts have to be written in Haskell or Plutus — functional programming languages whose specialists are in short supply in the crypto market.

The situation was aggravated by an insufficient number of stablecoins providing basic liquidity in DeFi. Major issuers like Tether (USDT) and Circle (USDC) have still not deployed native issuance on the network. Coins have to be transferred via cross-chain bridges and their wrapped versions used.

According to DeFiLlama, the total capitalization of "stablecoins" on Cardano lags significantly behind competitors, and algorithmic and synthetic alternatives like Djed have failed to provide the market with the necessary depth.

In April 2026, the Cardano Foundation allocated an eight-figure sum in ADA to market maker Flowdesk. The funds were directed to saturate key pools with liquidity in order to reduce slippage and strengthen the peg of the local stablecoins USDM and USDA.

As a result, market makers and institutional investors steer clear of the network. Due to the absence of familiar derivatives, the lack of native fiat pairs and throughput limitations, they have nowhere to deploy capital.

Has too little time passed?

The current ecosystem crisis highlighted the mental and strategic gap between Charles Hoskinson, the Cardano Foundation and retail investors. While the community demanded marketing activity and an influx of liquidity, Hoskinson distanced himself from the Web3 trends toward transparency.
