Mt Gox Founder Proposes Hard Fork To Recover Lost Bitcoin

Mark Karpelès has put forward a new idea aimed at recovering billions in Bitcoin tied to the long running Mt. Gox collapse. The former CEO is asking the Bitcoin community to consider a protocol level change that could allow nearly 80,000 BTC to be redistributed to creditors.

The coins in question have remained untouched for more than fifteen years and sit in a publicly tracked wallet linked to the historic breach.

Good to Know

• Proposal targets recovery of 79,956 Bitcoin linked to Mt. Gox hack
• Estimated value exceeds 5.2 billion dollars at current prices
• Any recovery would require a Bitcoin hard fork and full node upgrade

Proposal Would Require A Hard Fork To Move Dormant Coins

Karpelès shared the plan through GitHub, suggesting a new consensus rule that would allow the locked Bitcoin to move to a designated recovery address without access to the original private keys. He wrote:

“These coins have not moved in over 15 years. They are among the most well-known and publicly tracked UTXOs in Bitcoin’s history,” he wrote.

Under the concept, funds would then fall under the existing distribution process already managed by Mt. Gox trustee Nobuaki Kobayashi, who continues to oversee repayments tied to the bankruptcy estate.

Karpelès added:

“I want to be upfront: this is a hard fork. It makes a previously invalid transaction valid. All nodes would need to upgrade before the activation height. I’m not trying to disguise that fact or sneak it through as something else.”

Rather than pushing for immediate adoption, Karpelès framed the code submission as a starting point for discussion among developers, miners, and users.

“The MtGox trustee has declined to pursue on-chain recovery, citing the uncertainty of whether such a consensus change would ever be adopted,” he said.
“This creates a deadlock: the trustee won’t act without certainty, and the community can’t evaluate the idea without a concrete proposal. This patch breaks that deadlock by providing something concrete to discuss.”

Critics Warn Of Risks To Bitcoin Core Principles

Reaction across forums such as Bitcointalk was swift and often critical. Many participants argued that rewriting consensus rules to reverse a theft could weaken one of Bitcoin most valued characteristics: immutability.

“Each time a hack incident [happens], someone will call for another new consensus rule to recover stolen funds. This will destroy the bitcoin concept in full,” wrote a forum user known as coupable.

Another member, PrivacyG, questioned the influence of legal systems on decentralized networks. “Bitcoin should be independent from what Law Enforcement decides in any [jurisdictions],” the user said.

Karpelès acknowledged that philosophical concern represents the central challenge to gaining support, while maintaining that the Mt. Gox case stands apart due to broad agreement about ownership history and the visibility of the stolen coins.

Some Creditors Support Recovery Effort

Voices claiming to represent affected users expressed openness to the proposal, especially those who received only partial repayment during earlier distributions.

“If those coins ever move by whatever mechanism, then I am going to want my share of them back,” someone else said. “I’m a creditor and have been paid what little was left of my Bitcoin from the bankruptcy – I got about 15% back… I would support obtaining a court order to claim these coins.”

Mt Gox Collapse Still a Stain on the Crypto Industry Today

Mt. Gox operated from 2010 through 2014 and once handled roughly seventy percent of global Bitcoin transactions, making it the dominant exchange during early adoption years.

Security failures beginning in 2011 allowed attackers to siphon large amounts of Bitcoin, while internal technical problems contributed to additional losses that went unnoticed for long periods.

On February 24, 2014, a leaked document suggested insolvency after hundreds of thousands of Bitcoin disappeared. Bankruptcy protection was filed in Tokyo days later, with reports indicating losses of about 750,000 customer Bitcoin and 100,000 company held coins. At that time, the missing assets were valued near half a billion dollars, a figure that has since multiplied dramatically as Bitcoin prices climbed.
