• Introducing New Features: Developers might want to add new features or functionalities to the blockchain.

The planned upgrade for BCH didn't quite go as planned, leading to the reported issues by BitMex research.

The Alleged $1.3 Million+ Double Spend

The central claim made by BitMex Research is that a double-spending event occurred on the Bitcoin Cash network following the May 15th hard fork. Double spending is a critical vulnerability in cryptocurrency systems where the same digital currency can be spent more than once.This effectively creates money out of thin air and undermines the integrity of the entire system.

According to the report, a two-block chain reorganization took place, resulting in the double spending of approximately 3,392 BCH. BCH May Have Sustained $1.3 Million Double Spend: BitMex ResearchSource: CointelegraphPublished onAt the time of the incident, this amount was valued at over $1.3 million. Based on our calculations, around 3,392 BCH may have been successfully double spent in an orchestrated transaction reversal. However, the only victim with respect to these double spent coins could have been the original thief . Illustration of the Bitcoin Cash network splits on (Source: BitMEX Research)This is a substantial amount and represents a significant breach of security for the Bitcoin Cash network.

How Does Double Spending Work?

Double spending typically involves an attacker exploiting a vulnerability in the blockchain's consensus mechanism.Here's a simplified explanation:

1. Transaction 1: The attacker sends BCH to a merchant for goods or services.
2. Transaction 2: Simultaneously, the attacker sends the same BCH to a different address, often one they control.
3. Blockchain Manipulation: The attacker then attempts to manipulate the blockchain to ensure that Transaction 2 is confirmed while Transaction 1 is invalidated.This could involve creating a longer chain that includes Transaction 2 but excludes Transaction 1.
4. Double Spend: If successful, the attacker receives the goods from the merchant in Transaction 1 and also retains the BCH by controlling the address in Transaction 2. The new algorithm follows an agreement with Arweave, which will fund an audit of the new algorithm, an Arweave spokesperson told Cointelegraph via email on May 23.The same coins have been spent twice.

In this specific case, BitMex Research suggests that a bug was exploited shortly after the hard fork, potentially enabling the attacker to orchestrate this double spend.

Network Congestion and Reorganization

Network congestion and blockchain reorganizations can create opportunities for attackers to manipulate transactions.During periods of high network activity, it can be more difficult for nodes to agree on the correct order of transactions. BitMEX research says that the only victim of the recent double spend in BCH could have been the one who orchestrated the incident. BitMEX 리서치, 비트코인 캐시This can lead to temporary forks in the blockchain, which an attacker can exploit to double spend.

Insufficient Confirmation Times

Cryptocurrency transactions are typically considered secure after a certain number of confirmations.Each confirmation represents a new block being added to the blockchain, making it increasingly difficult to reverse the transaction.If confirmation times are too short, attackers may have a greater opportunity to double spend before the transaction is fully secure.

Mitigation Strategies:

• Rigorous Code Audits: Regularly conduct thorough code audits by independent security experts.
• Bug Bounty Programs: Incentivize security researchers to find and report vulnerabilities.
• Network Monitoring: Implement robust network monitoring systems to detect and respond to suspicious activity.
• Improved Consensus Mechanisms: Explore and implement more resilient consensus mechanisms that are less susceptible to manipulation.
• Longer Confirmation Times: Increase the recommended number of confirmations required for transactions to be considered secure.
