Bitcoin and Ethereum Blockchains Gain 51% Attack Immunity

Coin Metrics, a leading research company, has conducted a study shedding light on a significant development in the world of cryptocurrencies. The research indicates a remarkable immunity of the Bitcoin and Ethereum blockchains against 51% attacks, a vulnerability that has long been a concern for the crypto community.

In theory, a 51% attack refers to the scenario where malicious actors gain control of more than half of a network's computational power. This control allows them to disrupt transaction processing or even reverse transactions, posing a severe threat to the integrity and functionality of the blockchain.

Despite the theoretical possibility of such attacks, specialists assert that executing a 51% attack on the Bitcoin and Ethereum networks is practically infeasible. The sheer scale of resources required makes it economically unviable for attackers to carry out such assaults.

To launch a successful attack on the Bitcoin network, it would necessitate approximately 7 million ASIC miners, amounting to a staggering $20 billion investment, along with an additional $2 billion in electricity costs. Similarly, targeting the Ethereum network would require an investment of $34.4 billion for purchasing ETH for staking, managing 200 nodes, and utilizing cloud services.

Even if attackers were to succeed, the financial gains from double-spending or increasing transaction fees would not outweigh the exorbitant costs incurred. Thus, such attacks are deemed economically irrational and likely motivated solely by the intent to disrupt the networks rather than financial gain.
