It is a lazy Out-of-Core DataFrames (similar to Pandas), to visualize and explore big tabular datasets.
It calculates statistics such as mean, sum, count, standard deviation etc., on an N-dimensional grid for more than a billion (10^9) samples/rows per second.
Visualization is done using histograms, density plots and 3D volume rendering, allowing interactive exploration of big data.
Vaex uses memory mapping, zero memory copy policy and lazy computations for best performance (no memory wasted).
The data pipeline on your laptop will be super fast.

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. βOnce a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,β says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means itβs not controlled by any one organization. βItβs like a Google Doc that anyone can work on,β says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. βNobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.β
