A hash collision just happened


A smart contract address (0xc3ba5050ec45990f76474163c5ba673c244aaeca) generated in the Remix IDE on my local machine matches with an EOA (0xc3ba5050ec45990f76474163c5ba673c244aaeca) on Rinkeby in a transaction that happened 18 days ago. What is the chance for that?

Solution

  • The following four links are html codes of the contents in the Remix console. They match the graphs above. The address 0xc3ba5050ec45990f76474163c5ba673c244aaeca can be found in all four texts files corresponding to four functions call in my local Remix IDE. They cannot be the EOA on Rinkeby, which kinda work as proofs of this hash collision.
