To this point, the injury attributable to good contract assaults has reached $2 billion, and the assault on The DAO, essentially the most “well-known” crowdfunding challenge, has value greater than $50 million. The code can’t be modified after the good contract is formally run, that’s, the challenge can be in jeopardy as soon as the hacker is staying eyes on the vulnerability within the good contract.
