According to CryptoBriefing, research shows that Bitcoin networks are now more secure than ever. Analysts at ID Theory, a crypto-investment company, have calculated the equivalent days of Bitcoin's work proof (measuring the elasticity of the PoW blockchain), hitting a record high at the end of June after nearly seven months of near-continuous growth. . This indicator represents the time required to re-dig the blockchain based on the total hash value at the time each block was originally mined. Based on the ratio of the total work to the estimated historical hash value, ID Theory found that assuming a 100% hash, it takes about 450 days to rewrite the entire ten-year history of the Bitcoin blockchain.
