The Pentagon reveals flaws in Bitcoin and Ethereum blockchain

The Pentagon investigated and subsequently the security firm Trail of Bits published a report entitled “Are Blockchains Decentralized? », Or in French« Is blockchain decentralized? “. That report highlights flaws that could disrupt the Bitcoin (BTC) and Ethereum (ETH) blockchains. It was specifically funded by the US Department of Defense through the Defense Advanced Research Projects Agency (DARPA).

There would be flaws in the implementation of blockchains

Security firm’s Trail of Bits report generally talks about blockchain-based platforms using Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus protocols. However, it mainly focuses on the non-decentralized Bitcoin (BTC) and Ethereum (ETH) networks. The report states that cryptocurrencies are a blockchain network like Bitcoin (BTC) and Ethereum (ETH) “strong“. However, it is said that there are some vulnerabilities in the implementation of blockchain networks and consensus protocols.

The report generally states that existing blockchain networks are compromised a set of potential attack vectors and disturbance from external actors. He clarified that these networks could be “easily“more attack they are”a set of privileged entitieswith the power to modify their transactions.

The report specifically stated:For optimal blockchain distribution, there must be the cost of the so – called Sybil. There is currently no known way to implement Sybil costs in an unrestricted access blockchain like Bitcoin or Ethereum without employing a centralized TTP. Until a mechanism for executing Sybil costs without TTP is found, it will be almost impossible for blockchains without access decentralization to achieve satisfactory decentralization.“.

The Crypto community rejects the results of the Trail of Bits report

The encrypted community has been quick to dismiss the results of the work of security firm Trail of Bits as inaccurate. She recalled that the two largest cryptocurrencies by market capitalization are BTC and ETH based on the idea of ​​creating decentralized, transparent and open systems. However, the report seems to be skeptical of their purpose and suggests that they have failed in this regard.

Swan Bitcoin CTO and Co-Founder Yan Pritzker and Editor-in-Chief Tomer Strolight have released a report after studied the claims of Trail of Bits one by one. This report explains in particular that “a set of privileged entities»Can modify its code, because the user executes the nodes and determines which software code to run.

Moreover, he highlighted the difference between mining pools and miners. He pointed out that the former cannot disrupt the network as stated by the DARPA-funded report.

The U.S. Department of Defense has funded a report on defects that could affect the Bitcoin (BTC) and Ethereum (ETH) blockchain. The claim of this report published by the security company Trail of Bits is controversial by the crypto community.

Far from dampening my enthusiasm, an unsuccessful investment in cryptocurrency in 2017 only increased my enthusiasm. So I decided to study and understand the blockchain and its many uses and put forward my pen information related to this ecosystem.
