A high level presentation which will cover working with the popular public blockchains: Bitcoin, Ethereum and Stellar with python. The goal of the presentation is that attendees will understand high level the various popular public blockchains using python and how potentially they could use these in their next application.

A technical question, sir, please. If a blockchain is a distributed database. I would appreciate an explanation or reference. We just have to wait for china to ban bitcoins and this meme will be over. Every time I watch or read something on block-chain or any crypto currency, the more questions I have. On coinbase, you have a 5 minute window to cancel your order.

If your buying from a merchant, then you've probably got a bit more time. I can tell the bank to cancel or refund an outgoing transaction, and in the case of fraud there's recourse through the police. In bitcoin, it's gone forever. Don't assume everyone is in the US - the tax implications of bitcoin vary wildly 5. I've never used Gdax, if that's true then they're subsidizing your ideology. Coinbase charge a premium. Cardano, stellar lumens, and dash are virtually instantaneous.

Sending to a nonexistent address won't send. But just like cash, if you send it to a wrong address, then it is probably gone. Transaction fees are nonexistent if you use gdax. Coinbase will charge you a convenience fee. It is very very similar to the tulip bubble: Bitcoin is a digital Veblen good - It is a terrible money No path of recourse for scams or misspelled addresses 4. You have to keep a record of all transactions for tax purposes depending on the country 5.

You had to pay a fee to buy bitcoin Meanwhile with traditional currency I can make transactions cheaply, easily and safely because both the government and the banking system have my back. Well, if you mean deliberate Ponzi, that is definitely not the case, at least for Bitcoin; however, some of the lesser known crypto currencies are likely to be frauds.

If you mean natural ponzi to mean a bubble, that could quite possibly be depending on what you mean. It's not like the tulip bubble, because tulips make for terrible money as they meet some of the qualifications for money i.

They wither and lose value when divided. All market goods have their ups and downs, even extremes. Crypto is an anti-rivalrous good that has all of the qualities of money, and then some. Considering free market corrections resolve fast compared to the socialistic schemes of states, this is merely a buying opportunity on the next leg up. Remember the bitcoin crashes of , , , , , and ? Imagine someone has already found a vulnerability and they are just sitting there watching bitcoin grow and waiting for right time to strike Consequences are hard to imagine.

Well, that hypothetical person would also be watching bitcoin code change and grow, in despair I might add. So that's not really a viable scenario. As far as I know, all the exploits that have been done so far have been at predictable points in the exchange process. Phishing, trojans, insecure wallets and badly managed or fraudulent bitcoin exchanges.

I doubt there'd be any consequences. If something like that happened, the thing would instantly lose all value. The rest of them would just start from scratch.

It's just risky investors almost gamblers losing money. Still majority of populations didn't put their money in Bitcoin yet. Actually most people still don't know except tech people.

Can somebody explain to me why Stellar has less of an environmental impact than Bitcoin? That bit seemed to be sort of skipped over without a real explanation but it was the entire reason he chose to go for Stellar Such as Stellar, they have very smart dev teams and really valuable usecases, but if they do not have great marketing, the market buy up will be slower than if they had good marketing and therefore the price rise is slower.

Hope that cleared it up for you. The less trust the system has, the more computation heavy the transactions are. Hence, less trust takes more energy. That's my understanding anyway. I agree too that making a cryptocurrency has become a bit overwhelming, especially because the decentralized element is fading away day by day. Yes, but there is a huge amount of cryptocurrencies out there, and everyone can make their own like in a couple hours If you have the technical knowledge.

In fact, if you use less popular cryptocurrency you will probably give more of an impression of being into the cool tech world, specially if you start talking in every oportunity you have about how inferior is bitcoin compared to your cryptocurrency. Btw, bitcoin is a piece of shit, everybody who doesn't use BitcoinCash is a retarded fuck how can you be so stupid not to see the hundreds of times faster transaction times, and thousands of times smaller fees.

People have an actual reason to want gold they find it pretty, its tangible, you can build stuff with it, you can wear it, etc. Jupyter Notebook at 22 min has code.
