The blockchain is a distributed ledger that is completely open to anyone. They have interesting property, once some data get recorded inside a blockchain it gets almost impossible to change it. Understand blockchain as a spreadsheet or any database table which is duplicated across the thousands of systems in a network, and voila that’s what blockchain is.
A recently discovered vulnerability in the Sudo allows unprivileged users to run a command as root by specifying the user ID -1 or 4294967295. Sudo is one of the most powerful and commonly used utilities in all the Linux-based and UNIX Operating Systems. A vulnerability in that core utility has left everyone in utter confusion and frenzy.
Today’s computing is limited to having a single value of either 0 or 1 for each bit, quantum computing uses quantum bits (qubits) that are simultaneously in both states (0 and 1) at the same time. This phenomenon is called as the SUPERPOSITION. The consequence of this superposition is that quantum computers are able to test every solution to a problem at once. Further, because of this exponential relationship, such computers should be able to double their quantum computing power with each additional qubit.
