SegWit & Soft Forks & Sidechains, Oh, My! - Andreas Antonopoulos on Bitcoin

737 ratings | 36540 views
What is 'Segregated Witness' and what's its purpose? How do soft forks work and what do they make possible? What the %^&* is a sidechain? Innovation breeds innovations, says he -- the Grecian computer scientist who knows the disastrous consequences of currency monopolization all too well.

Amanda, you are awesome and so easy to fall in love with!!! The way you treated Andreas is not cool, though. If you got inspired by the Pixies, don't go out of your way to trash them and burn your guitar on stage, and compare them to Kiss. Respect and Peace!!!

Great interview Amanda! :) Andreas makes some great points, but I think most important of all, is the wealth extraction that has occurred in Greece and Cyprus and how it is spreading, which is why crypto is the answer to giving the people true financial independence. Keep up the great work, great questions you asked! PS, I love Aha Take on Me and reckon it is still one of the best songs of all time! Peace.

No.. its is not a good idea to "take the signatures out of the transaction" .. the transaction id should be the hash of the complete contents of the transaction, this is a fundamental design choice of Bitcoin. No transaction malleability should have been introduced when multisig was first implemented - the solution to that is to fix the first bug, not introduce another hack. With segwit we now have more than one transaction id for a transaction - which requires complex code gymnastics to handle - it breaks a fundamental design principle of Bitcoin. The solution to signature data taking up so much space, is to increase the blocksize to a reasonable level - more benefit for less complexity. Fortunately we have Bitcoin Cash so at least the market has a chance to vote for the Bitcoin they actually want - secure digital cash with low transaction fees.

bitcoin unlimited its another altcoin! for that we have Bytecoin BCN, that is better! it rised up 500% just today. Bitcoin BTC will go with segwit

Steffen Hauptmann (2 years ago)
Quite a nice interview with a very positive outlook for Bitcoin. But this will only come to pass if the miners really agree to incorporate all these inovative extensions. The problem for Bitcoin is that this does not happen. This is the sad state and it might lead many investors and users to abandon Bitcoin for something better. Miners advertise their "Bitcoin is the digital gold" idea and think it might be a good idea to leave everthing as is and get the transaction fees up. This will never work. It will kill Bitcoin because the people which are invested in Bitcoin are invested for its innovations. If innovation stops they will leave and the price can easily go into free fall.
Johny J (2 years ago)
SegWit is not bitcoin, it changes almost all the definitions in bitcoin, please experiment it as an alt-coin. Just like windows VISTA, so many bells and whistles and no one think that is windows. BTW, it is proved that a soft fork will cause an uncontrollable hard fork, see July 04 fork

I'm glad you asked about tradeoffs. There are always those. And if you don't mention them, you sound like a greasy salesman. It's easier to make changes. At first pass, that sounds great! But, _who_ is putting _what_ into the code? Immediately we bump into the issue. If we're cramming all these "innovative softforks" into the software, who makes sure that users want the features? How does this link with Blockstream's financial model?
Gaws (2 years ago)

Vention1MGTOW (2 years ago)
This is very encouraging. I was starting to feel a bit uneasy about the rate of innovation in bitcoin core. Sure there are tons of things being built around bitcoin but it was starting to look like bitcoin itself was getting hidebound. I'm glad I was wrong about that. This makes me a bit less reluctant to buy into the selloff that's happening right now. Some whale seems to be dumping bitcoins a bit at a time. Think I'll wait till he stops before buying. Anyway the bitcoin network capacity and transaction speed MUST be improved before bitcoin can really take off. I'm glad to hear that work is being done to make that happen. Thanks for posting this. I'll see if I can dig up a tip for you in addition to protip. This one was so awesome I'll kick in a 5(US) in BTC. BTW I see you take Ethereum. What's your favorite Ether wallet? I'm a noob.
Vention1MGTOW (2 years ago)
+The Daily Decrypt Thanks. I'll investigate them all.  I plan to throw about 3 grand in over the next 2 months. That will leave me enough surplus to get some silver too. I'm fond of using offline generated encrypted paper wallets and I've heard one of those web wallets can generate them, much like the Bitaddress website. If so, that's how I'll store most of the ether I accumulate. I don't like keeping too much cashola in the bank. I'm a "starve the beast" kinda guy. Every penny you can pull out of their system weakens them and makes you stronger. But it's piling up so I've got to dump it somewhere that's safe from the bank bail-ins that are headed our way, probably within 3 years if I'm right about this.  Thanks again. Truly awesome interview. Andreas is a huge asset to our community.
Amanda B. Johnson (2 years ago)
+Vention1MGTOW In addition, I've heard there's a light wallet for Ethereum now on desktop? So that may be preferable to a web wallet, depending on how much you want to hold. I'd imagine the Ethereum subreddit might be the place to find the link for that desktop wallet.
Amanda B. Johnson (2 years ago)
+Vention1MGTOW Hey, buddy. Thanks for the extra tip! Glad you liked the video so much. And I'd use ethereumwallet.com and/or holytransaction.com for Ether.

Also, once you learn one programming language, you can look at many others and pretty much understand what's going on, which is pretty awesome! So, for example, if you learn Java then you will also practically be learning JavaScript, Swift, C#, VB, etc at the same time because they are all very similar once you understand the principles behind them. It doesn't really matter what you build or on what platform (web, Android, iOS, PC etc), build whatever you want because it's not much of a problem to swap to another platform with it's own programming language and make something entirely different. There's still a learning curve, but it's no where near as overwhelming as when you're building something for the first time and learning your first language. I think that's handy to know because it can feel overwhelming at the start but you look back and realise it's really not.
Nick McComb (2 years ago)
+The Daily Decrypt if you want to build an Android app, look into Android app development videos, you'll notice that you have to download Android Studio to build an Android app and learn Java as well (watch a few YouTube videos for a good start). If you want to build an iPhone app get a Mac and download XCode to make the app, and you'll need to learn Swift to program the app (YouTube again). If you want to build a website (much easier than apps, for a basic website, and the best place to start) YouTube videos on HTML and CSS, then JavaScript. Start off building something basic with these tools, like an app that is a contact list, or a website that's a food menu, then build on it as you learn more about the tools you're using to build whatever it is you decide to build

How to become bitcoin trader? Exactly like Bitcoin, multiple digital currencies exist in the marketplace. So if you prefer to buy a few other currencies which aren`t available on Indian Exchange than you can utilize Bittrex. All you have to do is locate an exchange that you favor. Cryptocurrency exchanges have a massive potential to modify peoples minds and opinions concerning cryptocurrencies generally speaking and their application in actual life. So even in the event the exchange is attacked, its still true that you have your money. Furthermore, the exchanges prepare each and every industry for Bitcoin expansion. Existing stock exchanges will also compete to be able to fulfill the users configuration requirements. Sooner or later later on, the prices will grow more equal, meeting somewhere in the middleyour profit is equivalent to the quantity of convergence. No matter how far it is from Kijun, it is likely to return and test that level at some point. The amount of bitcoin is perpetually changing. In the US, it is 1000 USD. Whats even better, seek the services of a seasoned lawyer or at least ask for an in depth consultation. So youve read the newspaper about the meteoric growth of crypto currencies including Bitcoin or Ripple. Then coming up with 1000s of exchange rates simply to go out and get groceries is nearly impossible. Many cities around the world provide a bitcoin ATM where you are able to trade cash for bitcoin. The cryptocurrency world isn`t efficient.
