Blockchain, the solution to nothing
https://thecorrespondent.com/655/blockchain-the-amazing-solution-for-almost-... I found it particularly hilarious when the writer of the article asked the maker of the childrens' aid app if he had noticed that the app didn't actually need blockchain at all. "That's right." But the punch line was even better... Isn't it strange that you won all these awards despite not really using blockchain? "We keep trying to tell people, but it doesn’t seem to stick. You’re calling me about it again now … ” -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
It's really funny. It's more the result of "lets use blockchain!" on everything that creates those issues. And blockchain is hyper-overhyped... It can help in a few specific problems, but not on every single problem without exception. But everyone liked the concept and ran away screaming blockchain all over the place. Blockchain on email. Blockchain to rent a car. Blockchain-powered lettuce salad... that's insanity. I like the technology, I study it and sometimes I answer things on forums, but all the time when people ask me if I believe blockchain would help them, I say NO The "everybody must have everyone's data" is an issue. As the solution grows, the ledger grows, increasing the storage and processing requirements. With less people connected, you need an intermediary to access the blockchain, and those intermediaries can be attacked and take down the network. And there's few solutions to that. One solution is the blockchain used by former Raiblocks (now Nano). It's a DAG (directed acyclic graph), so any client will have only his own transactions, and not the entire ledger. That allows one to run a client on an ESP32, for example. there will be special nodes that store the entire ledger (like the Dash supernodes), but the clients don't need that. Who/what would use it? No idea... crypto coins, and not much else. And the smart contract solution... They aren't smart, they aren't contracts, and they aren't solutions. One mistake and everything crashes down instantly.The Ethereum DAO disaster, the Parity multi-signature contract, and that new DeFi that melted down in a day because people realized they made a mistake on the code, and nobody would ever have enough tokens to decide anything because of an arithmetic mistake. And many more examples. If the "contract" can be changed after creation, you cannot trust it because it can be useful now (like tokens on a web game that you pay to play), but later the owner changes the contract, pockets all tokens, and takes down the game. If it cannot be changed, any error on the contract is set on stone forever with deadly consequences. There are some countermeasures to that, like proxy contracts: a main contract references secondary contracts with the functions, but the main contract holds the data and the tokens. if a secondary contract is found to have an error, you deploy an amended version, call a function on the main contract to reference the next one, and done. The downside is that it is more expensive to run this contract, and the owner can, you know, replace the secondary contracts and steal everything. You can add multi-signatures, quorum, external oracles, but those only increase the cost and put a little protection against a rogue owner. There are very few things that blockchain can be useful, and one of them is distributed storage. Siacoin and Storj, for example, let you rent the extra space on that 4tb disk you already have for some coins. It is not profitable enough to make you buy storage just for that purpose, but you already have the space, right? And you can rent some space on the network for backing up things when you will reformat your computer, and want to store your data in case something breaks. It's cheaper than anything else, even cheaper than amazon glacier. Those supply chain management things are useful too, if you can integrate it correctly (and that's a BIG if). If you own a bakery, for example, you scan all the ingredients you have, store them all on your wallet (or have your purchasing software do that automagically) and any time any of your suppliers have any recall on something you got, you are warned. And everything down the line gets warned that they bought a recalled bread from you. Your customers don't even need to get back to you so you reimburse them, the next time they come to buy something they already have a credit for that contaminated bread you sold to them last week. But to integrate everyone is a nightmare, there are lots of privacy issues, industrial secrets issues... on a limited scale, it can work. Too limited and doesn't solve anything. Too broad and all that privacy issues get into your face. The fact is that there are very few cases that blockchain can be used that a database cannot. And databases are here since a long time ago, everyone knows how to build them, operate them, backup them, and extend them.

Say it aint so... Are you telling me that your don't believe that the blockchain is the solution for everything from climate change to erectile dysfunction. But seriously. There are some real uses for blockchain technologies but what we are seeing is a repeat of the .com bubble. Where if you had a wacky idea and stuck the words "on the internet" in it somewhere and did your pitch you could get millions in funding. Hey. Have I told you of my plans to handle garbage disposal "on the blockchain"..... The ICO is next week. People do this kind of thing constantly. Take a good idea and then push it till it is an amazingly bad idea. As for Siacoin and Storj I found that they used 100% of my available internet bandwidth without using any storage. Luckily for me I opted for "unlimited bandwidth" but not so lucky for Teksavvy. So doing something like sharing your few free TB could cost you big time if you were a Bell or Rogers customer. I have access to large amounts of excess storage but I have yet to be convinced that I could even pay for the power that it takes to spin the drives.

you can also interchange "blockchain" with "AI" ? as someone who started using my own AI tech in 2010 already, it never amazes me how many people the past year or two uses "AI" somewhere and in something - where it is not really "AI" but either simple timers or very basic machine learning or simple pattern identification. so, I guess in the recent words of the most powerful brain[1] on the planet when told about 162 086 covid-19 related deaths: "...it is what it is..." maybe worth 1c ?

If you have a VPS, or a co-located server, or something like that, and unlimited bandwidth, SIA and Storj are good to pass some time. The economics aren't on the side of the storage owners, but on the storage renters. It's so cheap that you can rent a terabyte on both networks, and use it for double backups. I stored maybe 200GB of data for a year, and maybe made 10 cents. Maybe less. And as an earlier adopter, I earned some hundreds of GB for free that I never used. I once was toying with this idea of providing low price backup solution to small businesses, storing data on Storj and SIA at the same time. Both networks aren't still "production ready", so I would store on both at the same time, and keep watching if the files are still available periodically. You only need enough storage to store all the metadata (client id, file name, size, the hash of it on the network, etc) on your database. So you could store a petabyte of data while having a couple GB on your server. The agent would upload directly to the networks and send you only the data you need to restore the file later. It can work, storage is not the difficult part, and the "what changed since last backup?" question is the main issue.

The problem was not so much that it was using up my 25MB that I am running at home but that it was hogging ALL my bandwidth causing congestion problems. I could likely do something with traffic shaping but I was not all that invested in the project to try to see how to make it workable.

If the economics don't work in the long run for the storage providers then those providers will exit the application. If I remember correctly a number of years ago HP had a storage service that was hosting LOTS of data for people. They decided the economics were not in their favor and shut it down causing huge inconvenience and problems for the customer base. What do you do when you have a huge data-set with a storage provider that will take months to move and get told they are closing down before you can extract all your data? When Storj/sia take their 30% off the top and then distribute the rest to the 3 to 5 storage hosters your looking at a vanishingly small return on your effort. Combine this with network latency related penalties and the home user with a few TB of space to share will not be interested sharing the space. It has been a while since I looked but I never found any business cases for storage providers. I don't expect to become the next Jeff Bezos by selling my storage space but I do want to know that I will cover my costs and make a bit.

Since the various services are object stores then why not just store eachfile as an objects and then keep track of the objects that change. It would be no better/worse than a regular filesystem backup like dump.
