What Will Happen to Cryptocurrency If the Blockchain Stops: An Analysis

The recent closure of the once highly popular crypto project Blast and several blockchain stoppages in 2026 have shown that even the most technologically advanced projects are not immune to serious failures, and in some cases, to complete shutdowns. We analyze what happens to balances, open trading positions, and the ability to withdraw funds when the blockchain stops.

It is important to immediately distinguish between two scenarios. A complete shutdown or closure of the network is a managed process in which the team winds down the project and asks users to withdraw their funds. A technical temporary halt of the blockchain is the cessation of block production, after which the network usually resumes operation.

In early October 2026, the team of the second-layer network based on Ethereum, Blast, announced the cessation of the project. The reason was economic unprofitability: the costs of maintaining the network exceeded revenues, and the team saw no realistic path to self-sustainability. Users were advised to withdraw their assets to the main Ethereum network by October 26, 2026. Thus, this example relates to the first option—a complete shutdown of the network.

The second scenario—a temporary halt of the network's operation—can be attributed to a number of cases. Throughout 2026, several networks based on Cosmos technologies, as well as major projects like Sui and Base, experienced voluntary and forced stoppages.

In all these cases, the blockchain effectively stops producing blocks, and no transactions are confirmed in the network. This means that transfers, deposits, or withdrawals from exchanges are impossible. Platforms cannot credit deposits because they do not see transactions in the network, and the network that has halted block production cannot process them. Withdrawals, in turn, require the exchange to initiate a transaction in the network, which cannot process it due to the stoppage.

Risks for Trading

Trading cryptocurrencies that are issued on the basis of a halted network does not stop. This is possible because the main trading activity occurs on centralized exchanges (CEX) such as Binance, Bybit, OKX, and other platforms. Thus, a temporary halt or closure of a project does not affect centralized trading mechanisms from the blockchain's perspective.

The cessation of trading may only affect decentralized exchanges (DEX) that operate on the basis of the halted network due to the inability to conduct operations. The cessation of trading operations can also be initiated by CEX, but this is an internal decision of each individual exchange. Moreover, on CEX, crypto assets that no longer exist on the blockchain can continue to be traded for a long time.

The same applies to futures contracts on individual cryptocurrencies, which often continue to be traded on exchanges even after the blockchain has stopped. Such situations are exacerbated by the fact that during the network stoppage, liquidity concentrates on fewer trading venues, spreads widen, and the index price becomes more volatile.

There are dozens of coins that were relevant in past market cycles, especially during the ICO boom of 2017, and then were abandoned by developers. Some of these blockchains continue to operate, and their tokens can technically still be transferred. However, exchanges have long ceased to support them, liquidity in pools and exchanges has disappeared, and the token price has fallen so close to zero that aggregators have stopped tracking it. According to Coingecko, over 13.4 million tokens stopped trading on GeckoTerminal between 2021 and 2025.

Something similar happened with Blast. By the time the project was announced to be closing, which had already been effectively abandoned, the BLAST token had lost almost 99% of its listing price on exchanges. After the news of the network's cessation, its price plummeted even further.

What Happens to Cryptocurrencies After the Network Stops

When the blockchain stops producing blocks, no transactions are confirmed. However, this does not mean that assets in this network disappear. Balances are recorded in the last produced block of transactions and remain unchanged until the network resumes operation.

In most cases, after a restart, they remain exactly the same. In rare cases, developers have to roll back the transaction history and balance to some time in the past. For example, due to a vulnerability found in the Zano network in September, developers decided to roll back the entire transaction history a month back.

There are also less significant examples of history rollback, such as with the Cronos network in September. After an attack on the Tectonic project, which operates on this network, hackers withdrew $9 million. In response, developers decided to change the state of the blockchain and returned it to the moment before the hack, erasing several hours of transaction history.

The history is notable in that it involves not a little-known blockchain of a small startup. The CRO token is in the top 30 largest cryptocurrencies, and the Cronos network is associated with Crypto.com, one of the largest crypto exchanges in the Western market.

This is fundamentally different from the situation with the closure of a network, as in the case of Blast, where the team announced a complete shutdown of the network. This means that after the specified deadline, users will not have the opportunity to transfer funds in this network.

Even after a complete shutdown of the network, assets do not disappear but are preserved in copies of the blockchain, which is stored on separate devices. The only difference is that in such a blockchain, no transactions occur, and there are no users utilizing the assets in any way.
