async/await is just the do-notation of the Promise monad

CertSimple just wrote a blog post arguing ES2017's async/await was the best thing to happen with JavaScript. I wholeheartedly agree.

In short, one of the (few?) good things about JavaScript used to be how well it handled asynchronous requests. This was mostly thanks to its Scheme-inherited implementation of functions and closures. That, though, was also one of its worst faults, because it led to the "callback hell", an seemingly unavoidable pattern that made highly asynchronous JS code almost unreadable. Many solutions attempted to solve that, but most failed. Promises almost did it, but failed too. Finally, async/await is here and, combined with Promises, it solves the problem for good. On this post, I'll explain why that is the case and trace a link between promises, async/await, the do-notation and monads.

First, let's illustrate the 3 styles by implementing

# on mac: brew install tree
# on linux: yum install tree

## the XML output is 5 directories deep and filtering any folder name with "tmp" in it
tree -d -L 5 -X -I tmp /Users/karl/Dropbox/CodeNinja/GitHub | sed 's/directory/node/g'| sed 's/name/TEXT/g' | sed 's/tree/map/g' | sed '$d' | sed '$d' | sed '$d'|  sed "1d" | sed 's/report/\/map/g' | sed 's/<map>/<map version="1.0.1">/g' > /Users/karl/Dropbox/CodeNinja/GitHub/Gitmap.mm

## to filter multiple folders do the following
tree -L 7 -I "tmp|node_modules|bower_components"

Stealth Addresses, Transactions and Messages

Normal bitcoin addresses cannot be published in public without losing all privacy, since all transactions to that address can be seen by anybody. Stealth addresses let us publish an address in public which can be used by payers to derive a new address that the payee has access to, but no one else knows is associated with the stealth address. The trick is that the payer must use a nonce to derive the address paid to, and this nonce must be delivered to the payee so they know how to recover the funds. This nonce can be delivered in the transaction, so that no separate channel is required to communicate the nonce.

The same technology can also be used to construct new public keys to send encrypted messages to.

We will discuss four methods:

1. The simplest form of stealth addresses, which has some drawbacks that can improved upon.
