Ravencoin is facing a major problem after attackers used a serious flaw in its software. The issue could force the network to erase about four days of recent transaction history. The event has raised concern among users, exchanges, and traders because payments that looked complete could disappear from the blockchain.
The first bad block appeared on August 7 at block height 4,487,776. It came at 15:44 UTC. After the flaw became known, more invalid blocks appeared on the live network. Ravencoin has since released a fix for the software, but that fix cannot remove blocks that are already part of the chain.
The current crisis now centers on which version of the blockchain the network should accept. Two large pools, 2Miners and RavenMiner, control most of Ravencoin’s computing power. Both are now creating a replacement chain from block 4,487,775, which was the last block before the attack.
Why a Rollback Could Happen
A blockchain is a record of transactions. New blocks add more information to that record. Normally, once a transaction receives enough confirmation, users expect it to remain part of the permanent history.
Ravencoin is now in a different situation. The bad blocks came from a software weakness that allowed invalid blocks to enter the chain. This means some transactions made after the first bad block could become part of a chain that the network later rejects.
The two large pools have chosen to rebuild the chain from before the first invalid block. If enough miners support this new version, the network could replace the recent history with a clean chain.
For ordinary users, the result could be very serious. A payment that looked complete over the weekend could vanish from the record. The coins could return to the sender, while the person who received them could lose the expected payment.
Exchanges Face a Major Risk
Crypto exchanges face one of the biggest risks from this problem. Imagine a user sends RVN to an exchange. The exchange sees the deposit and gives the user credit. The user then trades those coins or withdraws another asset.
If the original RVN deposit later disappears after a chain change, the exchange could lose money. It may have already given the user access to funds that no longer exist on the accepted blockchain.
That is why some exchanges have already taken action.
Amsterdam-based Bitvavo suspended RVN deposits and withdrawals as a safety measure. South Korea’s Upbit also stopped deposits and placed an investment warning on RVN across its won, bitcoin, and tether markets. These steps show how the blockchain problem can quickly affect the wider crypto market.
Two Pools Choose a Clean Chain
2Miners and RavenMiner are at the center of the current response. Together, the two pools control most of Ravencoin’s computing power. They have chosen block 4,487,775 as the base for their replacement chain.
The Ravencoin project asked the two pools to restart from a later block. Such a choice would reduce the amount of history at risk. The pools did not accept that request.
RavenMiner said its nodes now use an emergency software fix and support what it calls the clean chain. Blocks made during the attack period will not remain on that version of the network.
The pool has also paused payouts until the network reaches a clear result. It said it would cover any shortfall itself. RavenMiner also said earnings from before 15:44 UTC on August 7 are safe and are not part of the affected period.
What Could Happen to Recent Payments
The most important issue for users is the fate of transactions made after the first bad block.
If the replacement chain becomes the accepted version, transactions from the affected period could disappear. This does not mean every user will lose funds. The effect will depend on the exact transaction, the chain that survives, and how exchanges and other services handle the change.
The main risk is for people who received RVN and then used those coins before the network settled the issue. An exchange that accepted a deposit could later discover that the deposit is no longer part of the accepted chain.
This is why exchanges have moved quickly to stop deposits and withdrawals. Until the network settles on one version of its history, new RVN transfers carry extra risk.
Ravencoin Has Faced Attacks Before
This is not the first major security problem for Ravencoin. The network faced another serious attack in 2020. At that time, attackers used a flaw that allowed more RVN to be created than the rules permitted.
About 31 million extra tokens were created before the problem was fixed. The latest event is different, but it again shows the risks that can exist when a blockchain has a software weakness.
Ravencoin is a fork of Bitcoin’s code. It launched in January 2018, on Bitcoin’s ninth birthday. Its main purpose was to let users create and issue their own tokens on the blockchain.
RVN Price Takes a Sharp Hit
The network problem has also hurt the price of RVN. The token fell 17% over 24 hours to about $0.0029.
At that price, Ravencoin had a market value of roughly $48 million. Trading volume stood at about $10 million. RVN is also down 77% over the past year.
The price drop shows that traders are worried about the effect of the network problem. A blockchain needs trust from users, exchanges, and market participants. When its recent history comes under doubt, confidence can fall very fast.
For a smaller crypto asset such as RVN, a major technical crisis can have an even larger effect. A suspension at major exchanges can reduce access to the token, while fear can push more holders to sell.
Why the Event Matters Beyond Ravencoin
The Ravencoin crisis offers a simple lesson about blockchain security. Many people see a blockchain as a record that cannot change. In normal conditions, that idea is close to the truth. But a serious software flaw can create a situation where the network must choose between competing versions of its history.
The event also shows why computing power matters on proof-of-work networks. Miners create blocks and help decide which chain becomes the accepted record. When a small number of large pools control most of that power, their choice can have a major effect on the network.
In this case, 2Miners and RavenMiner have chosen to rebuild the chain from before the exploit. Their decision could determine whether several days of transactions remain valid.
What Users Should Watch Now
The next major step is the final choice of chain. Ravencoin has already released a software fix, but the network still needs to settle its recent history.
Users should pay close attention to official Ravencoin updates and exchange notices before they send or receive RVN. Deposits and withdrawals may remain closed until exchanges have confidence in the accepted chain.
The key date is August 7, when the first invalid block appeared at 15:44 UTC. Transactions before that point are not part of the reported rollback risk. The affected period begins after that first bad block and could cover several days.
For now, the biggest question is simple: which version of Ravencoin’s recent history will the network accept?
A Critical Test for Ravencoin
Ravencoin now faces a difficult test. The project has fixed the software flaw, but the network must also deal with the blocks that appeared before the fix.
Two major pools have already chosen a clean chain from block 4,487,775. Exchanges have taken protective steps, RVN has lost 17% in 24 hours, and users face uncertainty over recent payments.
The situation also shows how a technical problem can quickly become a market problem. A software flaw first affects the blockchain, then exchanges, then users, and finally the price.
Until the network settles on one clear chain, caution remains important. The coming decision will determine whether the recent four-day history stays in place or disappears from Ravencoin’s accepted record.
