🌲 #newfeature Compiler warnings Warning messages are now issued in certain circumstances when you add a script to a chart. This is one example, for cases where you initialize a new instance of a global variable in a local scope with = instead of assigning the global scope variable a new value using :=. We called those "silent killers" because they were rarely intentional, yet sometimes difficult to spot when debugging code.
Here is an example of code that will generate a warning when you add it to a chart:
//@version=4 study("") a = 1 if close > open a = 2 plot(a)
In this case, variable a will never plot with a value of 2 because it is initialized in the if statement's local scope and disappears from view when the block ends. The coder's intention would have required, instead:
//@version=4 study("") a = 1 if close > open a := 2 plot(a)

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. “Once 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,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
