Ethereum is an open-source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. Ether is a cryptocurrency whose blockchain is generated by the Ethereum platform. Ether can be transferred between accounts and used to compensate participant mining nodes for computations performed. Ethereum provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. “Gas”, an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.
Ethereum was proposed in late 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer. Development was funded by an online crowdsale that took place between July and August 2014. The system went live on 30 July 2015, with 11.9 million coins “premined” for the crowdsale. This accounts for approximately 13 percent of the total circulating supply.
In 2016, as a result of the collapse of The DAO project, Ethereum was split into two separate blockchains – the new separate version became Ethereum (ETH), and the original continued as Ethereum Classic (ETC). The value of the Ethereum currency grew over 13,000 percent in 2017.

6 Tips for Building Your Business with Twitter
Twitter is all about relationships, growing your circle of influence, and yes, RELATIONSHIPS. The better (re: closer) your relationships on Twitter, the more likely people are to retweet your stuff, visit your Facebook page and websites, join your lists and buy your products. So how do you rapidly grow your Twitter following while wielding influence over your followers? Here are 5 tips…
1. Be Yourself. Often times people think they’re somehow ‘not good enough,’ and so they pretend to be something they’re not. The problem is people can smell a phony a mile away. Don’t attempt to be Mr. Know-it-All or Ms. Perfect because nobody is buying that nonsense, and even if they were, they want to know REAL people with real lives, real challenges, and real things to say. Always stay true to yourself because you are a one-of-a-kind original, and as they say, everyone else is already taken anyway.
2. Appreciate Your Followers. Re-tweet their best tweets (or the tweets that are the most important to them.) Give them a #FF, which means you’re recommending others follow them. Or even send them a direct message. In other words, don’t just interact – promote others and expect nothing in return. The more value you can give to others, the more they will like you, appreciate you, and want to reciprocate.
3. Connect With The Big Dogs. Whatever your niche is, find the influential people in your niche and engage them. Being seen with people in authority is one of the quickest ways to be seen as an authority yourself. Plus, their audience will also notice you, and you’ll gain followers who hold an avid interest in your particular niche.
4. Engage Engage Engage. Answer everyone who engages with you, and see how many followers you can engage yourself. You never know who is going to become your next big client or customer – it could be that new guy with only 5 followers as easily as it could be the seasoned Twitter person with 50,000 followers.
5. Add a Heap of Pizzazz. We’ve already said you need to be yourself, and this is perhaps the best advice anyone can give you. That said, it’s okay to take yourself up a notch. You are unique, so go ahead and amplify that uniqueness and be a little bit larger than life. Be friendlier than you are in real life, be a little bit more flamboyount, go ahead and have opinions (your REAL opinions, that is) and by all means, STAND OUT from the crowd. That last thing you want to do is be a wallflower.
And even if you’re shy in real life, that’s okay. This is the Internet, and so it’s not like trying to be the life of the party in real life – it’s more like portraying yourself in the best light, with the most fun, and the least inhibitions. Frankly, there is no better place for shy people than Twitter – it’s a great way to meet tons of people with absolutely zero risk. After all, you don’t have to send a tweet until you’re certain it says exactly what you want it to say – so you can get it right every time.
6. Have fun. Need I say more? People like to hang out with people who are having fun, and Twitter is no different. So go ahead, have a blast, let the good times roll, and watch your follower numbers increase accordingly!
