Bitcoin and other cryptocurrencies are gaining more attention as days pass. Aside from the advantages that cryptocurrencies have like anonymity and easy international transactions, people are enticed by the fact that it can become a good investment. Apart from trading bitcoins for cash, you can also use bitcoins to buy gift cards, book flights, and hotels, buy furniture, or even buy real estate properties. Bitcoin purchases are not taxed at the moment since there is no way for third parties to identify, track, or intercept transactions that use.
Blockchain (and Bitcoin first, of course) is often described as a technology that allows peers to transfer value between each other in a trustless way. However, “trustless” is not entirely accurate, but more like a convenient and short way of describing it. Truth is, there is still a lot of trust involved… but with a twist. Let me ramble on about that for a few minutes.
Selling software is not an easy task for start-ups today. The market is big, solutions abound, and there are very large and distinguished corporations in the market.
Okay, let's start with what does not work: have you ever heard someone offer "integral solutions", "applications in any language", "software maintenance", "project development"? No matter how sophisticated and efficient it sounds, it does not say anything specific; besides, let's be honest, even though you can dedicate yourself to everything, it is not optimal for a start-up because intellectual resources can abound, but humans can not, and if you want to maintain a good standard of quality, you have to specialize.
You might have heard that Blockchain is immutable, but that is a lie!... well not quite, but the ledger is technically modifiable.
One of the many things I found very interesting about the concept of Blockchain introduced by Bitcoin, is how the Proof of Work model works, and how it makes the blockchain immutable (among other things). Specially when you consider that digital data can always be modified, no matter what. The blockchain technology deals with it, and thinks ahead. That’s an important aspect when you are trying to build a system for transferring value in a trustless* way.
I want to share my experience with Firebase Realtime Database and it's integration with Android using the "offline" mode it provides. I won’t get into a lot of technical details but instead I will give a few highlights of how it was for me.
Spoiler alert... it was great!
