Ivan on Tech by Ivan Liljeqvist
Very good explanation. Thank you. Can you explain the different between Lightning Network and Liquid Network.. I read that they both complement Bitcoin. One is for small payment and the other is for like institutions?
Your channel is very interesting for sure. I have a question chrome keeps downloading pepflashplayer.dll without my consent and norton approves it. I know things have been weird with chrome lately with there extensions. Is there a way I can block this or would it be considered safe by norton says 10s of thousands of downloads but that’s not to say it’s safe right? Just not sure what to do. Thanks!
How does the blockchain explore know where to find the blocks? It's URLs all the way down. But doesn't there have to be a central authority somewhere (even if it's replicating in real time) that all the participating computers are reporting their blockchain traffic to? Or , when you create an explorer, the reality is that it's impossible to examine all the traffic, but only a random sampling/parition/shard/etc. of the entire traffic pool. You can only show a sampling of the traffic pool, and the content of that sampling is determined the PCs you do query about the part of the traffic pool they have handled or seen? For example, where do you find a list of URLs to make blockchain queries to?
In my mind this brings up the idea that Bitcoin or other coins that are decentralized cannot be stopped. If the providers can throttle certain sites why can they not throttle Blockchain? I know it is coming from many different addresses versus say maybe just a couple from a company like Netflix but couldn't they just block that code? There has to be a certain script affiliated, No? Anyone running a node be blocked or throttled? I've asked this question before and everyone just says it can't be stopped and not why. Thanks Ivan!
I disagree saying that where the frontend lives is not important. If you want true decentralization, you should have no servers. Think of government banning something, they can do that with a centralized frontend. It will be nice when completely replace ICANN and decentralize DNS and frontends. I'm working on a project like this, let me know if you're interested.
This is similar to IPFS. Can you talk about it? I think that this new internet architecture is emerging because the personal computer of today is so powerful that it can act as some sort of server. The increasing capacity of hard drives also plays an important role in this change. In fact, I believe that the revolution started long ago with mp3 files, that allowed a lot of music to be stored in the regular computers and easily shared over the internet.
This movement is related to Ethereum and to the idea that the internet is broken, and we have to fix it. The initial idea of decentralization is lost, and most of the internet is controlled by a few companies.
so the backend would be like video files php and database data and this would be in the blockchain web 3.0? but we would need to host the front end which would be css html and domain right? would the domain name be part of the backend on the blockchain?
Nice one Ivan, but can you please part-2 on how the block explorers work, because ideally to fetch transactions for a particular bitcoin address the query might not traverse through all the blockchain, match the address and get its transactions which is kind o naive. From my research I have noticed the blockexplorers have modified the clients for faster data retrieval it appears, but there is not a lot of information how to do it ? At its core what kind of architecures are we seeing in the block explorers ?
It’s just Instagram, haha I record some stories using snap because of funnier filters and then post them on insta. I don’t use snap at all actually, just to record some stories that I then post to insta ❤️🦄
So if I understand this correctly; when information is broadcast and validated on a blockchain, there is no way whatsoever to permanently delete it?
How I understand it, the blockchain is a protocol (or a set of rules) by which different nodes within the network communicate with each other. Am I correct in assuming that if you disconnect every node from the network, the data would disappear? Or is this impossible? I'm really curious about how this works, it's so interesting!
Hi Ivan. You say that the frontend is centralized but that this is not important. Don't you think it's important that the frontend for a block explorer still adds a point of trust for most end users? Not a programmer, but my layman's logic says I think we'll do away with it in the future, we'll probably make this an integral part of web browsers (since web browsers are subject to a lot more scrutiny than a webpage, and easier to keep tabs on).
The main weakness in the whole blockchain system is that all blockchains are dependent on a minimum number of miners who actually hold all of the data for the blockchain, i.e. a crowd sourced database. I am extremely leery of enough anonymous miners being available over time or having large enough storage capacities to keep the blockchain house of cards afloat. There is a threshold that will be reached, and then what?
Great info. Next time u film turn off "AUTO colour-Balance" on your camera because every time you move your head to the side the colour shifts from cool to warm. It is distracting. Get your self a "grey card" learn how to use it and use it to set the colour balance at the beginning of every video. That way it stays set and doesn't shift as you move your head around. Best J.
Ivan, I like you. Your explanations and charisma are excellent. But please...just please, stop naming your series of videos "programmer explaining"... It is not serious. It is very rare that you explain coding..... and you've never did deep dive....as a software engineer myself it is not worth it....BUG....your channel and your explanations are excellent....I would even say amongst the best on the network....Cheers!
Great video, this technology really is the future. Could you talk about how block explorer could be used to circumvent censorship. Also anything that is made/posted on block based 'websites' is pretty much permanent because it will always exist on the blockchain.
How will block based websites host all their files etc, as they would take up huge amounts of storage and bloat the blockchain.
It gets really interesting when you imagine people could host files on storage blockchains like Sia, which could in theory store and serve up the content like images and videos, with the regular web blockchain explorer purely used for linking/ posting / text etc.
Love your videos, I sent you an email too and I appreciate how accessible you make yourself. Please cover iota and analyze it from a security standpoint, I watched the other video but I still don’t really get it.
Thanks Ivan, I really enjoy your videos, so much more interesting than the rest of YT who are mostly shilling.
Am I right in thinking it would be fairly easy to build a torrent tracker on blockchain, perhaps with a modified torrent client with access to this blockchain and a search engine for it?
How would you get the blockchain to run with no financial incentive? Would others using it to search be enough to power it?
Sia is a file hosting blockchain. At the moment it is shit and clunky but has huge potential. At the moment it is also just private, you can upload files to the network, and you pay a very small amount per GB per X weeks. It pays hosters who rent out their hard drive space based on storage rented and bandwidth usage. So there is financial incentive for renting out your hard drive space. All files are spread across multiple hosts for redundancy so you will never lose your files. So imagine if they could open that up, so that anyone can access the files, like public file sharing. The blockchain 'web' could use a similar tactic.
Very informative as always! On a different topic and since you're one of the most tech-savy Youtubers regarding blockchain and cryptos, I'm wondering what's going to happen once the last bitcoin is mined? Will miners will still be incentivized to maintain the network up and running if there's no BTC reward? Sorry if this is stupid question, but I'm new to this topic and I'm trying to learn as much as possible. Thanks Ivan, keep up the great work!
Evro Amor I think so far block explorers are centralised, the point Ivan is making is this doesn't matter its just the front door not the whole house. And we can throw up a new front door much quicker than building a house.
Ivan, I'd love to see a discussion on IOTA. It is gaining traction lately and rising in value. As a developer more interested in the underlying tech and what it enables, I'm very excited about the tangle and see it as the next evolution of DLT and a minerless DLT! It would be good to have a video explaining how IOTA and the tangle work. What issues the tangle addresses against current block chain tech and what issues it still faces. And perhaps comparing the tangles feature set against intended upgrades to existing blockchains. Do you think the work bitcoin and ethereum are doing truly solve the issues of scaleability and such, or are they bandaids that ultimately need a fundamental alteration in design (Such as the tangle).
Love the videos! thanks
Second again. The conversation about 51% attack is still going on. There are those who believe it can not happen and there is no reason any government or other entity can or would perform. I strongly disagree. I am arguing that China stating they will kill bitcoin is indeed a threat they could carry out considering the hash rate they have. Not making a lot of friends with my point of view. LOL It is fine. The more we talk about it the better off we are.
Perhaps and what would be your opinion that on December 10th Governments and banks can technically short without buying in to bitcoin. My experience with derivatives has not proven favorable for me. Why in the hell would anyone let the fox into the hen house? Putting bitcoin on the Chicago Mercantile can ONLY favor the wealthy! You think they are doing this to help you and me? To pour money in? They are not buying a single bitcoin! They are betting on the failure. They will short it to death by the 18th when it will be liquidated on CBOT. Man I hope I am wrong. I know my wife has a few dollars invested in bitcoin. I live in the U.S where a historic transfer of wealth is about to occur again. Screwing the poor and middle class again. For the idiots who think jobs will be created. The corporations are flush with cash now! They are NOT going to increase wages or expand their companies.
Karl Hensel I think it's unlikely because it requires all of the miners to comply with the government. I can't see this happening unless people are getting shot in the head. A lot of mines are hidden, and their owners would fight before they let their years of investment and wealth disappear. Do you think they'll comply?
Absolutely this is coordinated. The dollars value is very important to both governments. In addition they can not have the economic power in the hands of the masses. It must be controlled by the 1% so they can continue to dictate the terms of our existence.
