Ravencoin’s Long Fall Hits Bottom as Exploit Freezes Transfers

Ravencoin’s RVN token lost about a fifth of its value on August 11 after the project confirmed that attackers had spent four days exploiting a flaw in its block validation code. The first known invalid block was accepted by vulnerable nodes at height 4,487,776 on August 7, and by the time Ravencoin issued its public notice four days later, two of the network’s largest mining pools were already building an alternative chain that excludes the compromised blocks. The selloff dragged Ravencoin’s market capitalization down to roughly $46 million.

The Header Field That Made Forged Blocks Look Real

Ravencoin mines new blocks using KAWPOW, an algorithm built to resist specialized mining hardware and keep block production spread across ordinary GPUs. Every block header carries a field called nHeight, meant to record where that block sits in the chain. That field was supposed to be checked against a block’s actual position, and it never was. An attacker could manipulate the value to make a forged block look like it had completed the required proof of work when it had not. A researcher privately disclosed the vulnerability to Ravencoin on August 8, sharing a full technical analysis along with a proposed fix. Once the trick had been demonstrated on the live network, other miners appear to have copied it, adding more invalid blocks to the count over the following days.

2Miners and RavenMiner Race to Outrun the Compromised Branch

2Miners shipped an emergency patch, version 4.6.1.1-hf1, that rejects the forged blocks and checkpoints the chain at block 4,487,775. The pool identified 96 affected blocks scattered across a 2,089-block range, meaning any transaction confirmed in that window carries some risk of being reversed. 2Miners and RavenMiner, which together control a majority of Ravencoin’s hash rate, are now mining a chain that excludes the exploited branch entirely. Ravencoin’s team pushed for a gentler fix, but a request to adopt a more recent recovery point, one that would reduce disruption for users and exchanges, was declined by the pools. Upbit and Bitget both suspended RVN deposits and withdrawals as the situation unfolded, and Ravencoin urged every exchange, node operator, and block explorer still running the old software to upgrade immediately.

A Second Consensus Failure, Patched by a Mining Pool

This is not Ravencoin’s first consensus-level breach. In 2020, attackers exploited a separate flaw to mint about 315 million unauthorized RVN tokens, an incident rooted in excess issuance rather than block validation. The current bug sits in a different part of the system, tied to how the chain verifies proof of work and settles between competing histories, but the two episodes together mean the project has now had to rebuild user trust twice in six years. The patch that stabilized the network shipped from a mining pool, not from Ravencoin’s core development team. For a project whose entire security model rests on every node running correct validation code, having the fix arrive from an outside operator says something about who is actually maintaining that code.

RVN Closes Below a Trendline That Held Since March

RVN has been sliding inside a descending channel on the daily chart since March, with the lower boundary holding on every prior test. Today’s candle closed clean through it, the first close-through since the channel formed. Wicks below a trendline happen constantly and usually get bought back inside the same session. A close below it means sellers held the level all the way into the daily settle.

Price is also trading beneath both the 50-day moving average and the 200-day average, rough markers of where buyers have been positioned over the last 50 and 200 trading days. With price under both, there’s no obvious pocket of trapped buyers nearby who might step in and defend a level on the way down. The 14-period RSI sits at 18.56, the most stretched oversold reading anywhere on this chart, below even June’s capitulation low. An RSI this low usually reflects exhausted selling pressure, but oversold readings can persist for several sessions once a move turns into a liquidation cascade rather than ordinary profit-taking.

The setup splits. A relief bounce toward the $0.00370-$0.00416 zone, where the 50-day average and the 0.236 fib level overlap, would fit a standard oversold mean reversion. Continuation lower would fit if the selling is being driven by something structural, forced liquidations or exchange-specific flow tied to the frozen transfers, rather than by sentiment alone. Whether today’s volume was outsized against the past month’s average is the piece still missing before calling this exhaustion versus the start of another leg down. (Analysis: Alexander Stefanov)

Why Frozen Transfers Could Outlast the Price Chart

Transactions confirmed inside the compromised block range stay in limbo until the 2Miners and RavenMiner chain builds enough work to overtake the branch it’s trying to replace. How long that takes depends on what share of Ravencoin’s remaining hash rate follows the two pools rather than continuing to extend the old branch, and neither pool has published a hash rate estimate for the clean chain yet. Exchanges are likely to keep deposits and withdrawals frozen until that resolution is confirmed on-chain rather than simply announced, which means liquidity on order books could stay thin for longer than the price chart alone suggests.
