What is meant by a blind write in a schedule?
If there is no read that happens prior to the first write then it is said to be a blind write.

Example. Consider the following schedule:




W3(X) is a blind write, as there is no read before write [R3(X) before W3(X)]
W2(X) is not a blind write, as a read happens before write [R2(X) before W2(X)]
