I was just like you until a few months ago, when i got really interested in the technical aspect of DLT. Don’t let the digital currency scam blind you : there are some really really interesting things going on in that field.
i don’t know a lot of database that you can share between any number of parties with write priviledges and yet be sure none of them can destroy, alter, falsify data or even make them unavailable , and which you don’t even need to host yourself.
There are some very peculiar properties of a dlt, that makes them special.
I had a job in a company obsessed with DLT. I didn’t see anything useful. In fact I’d go as far to suggest that the only use of a blockchain is in cryptocurrency. What have you seen which suggests otherwise?
Maybe you’ve got more insights on the subject since you’ve actually had a job on the tech, but it seems that « private » DLTs , or « b2b » dlts could have some applications where competitors need to share and persist information.
Another is with all systems taking the roles traditionnally filled with state actors ( registers of some sorts).
But you’re right, so far no « killer app » has been found. That’s what makes it interesting today, imho.
edit : to answer your question more precisely, a talk by one of hedera founder to a university class was eye opening to me ( here : https://www.youtube.com/watch?v=IjQkag6VOo0)
Bitcoin is coming up on its 9-year anniversary. The equivalent point in the web's history was 1998.
How many of today's Internet giants were founded in 1998? Amazon. Plenty of defunct also-rans: Netscape, Ebay, Yahoo, AOL, Geocities, Altavista, Excite, Infoseek, Lycos, Pointcast, Monster.com, RealAudio, Pets.com, Kozmo, AllAdvantage.com, Webvan, DoubleClick. Netflix was in its infancy (~1 year old). Apple was a dying hardware company, a few months from bankruptcy and kept alive by Microsoft's cash infusion.
Google's official founding was several months in the future. PayPal was right around then. Napster was a year in the future. Friendster and LiveJournal were 4 years in the future, MySpace 5 years, Facebook almost 6. SomethingAwful.com, Bodybuilding.com, and Fark.com were a year in the future, 4chan 3 years, Digg 6 years, and Reddit 7. Twitter was 8 years in the future. YouTube was 7. Heroku and Weebly were 8-9 years in the future, which was the same time SquareSpace graduated to more than one employee. Dropbox was 8 years in the future. AirBnb was also 8 years, but didn't catch on for a further 5 years or so. Indeed was 6, Etsy was 7, Indiegogo was 9, Kickstarter was 11, GoFundMe was 11, Pinterest was 12, Patreon was 14.
So to answer your question going by the web's example - probably about 7 years. The "killer app" for the web (communication & coordination, IMHO) started becoming apparent to the mainstream around 2005, with Facebook, Reddit, YouTube, Etsy, Indeed, and Twitter all being founded within +-1 year of that. Interestingly, analogues of all of them existed in 1998 (Classmates.com, DejaNews, RealVideo, EBay, Monster, and...well, nothing really for Twitter), but it took almost 20 years for the underlying infrastructure to get mature enough to get mass consumer adoption.
Within the last 3 years: Magic Leap, AR/VR in general, Theranos, Elon Musk's cave-diving submarine, Juicero, self-driving cars, drone delivery. Smartwatches, smart-home speakers, and IoT are roughly tied with blockchain for hype/use ratio.
I disagree. Smart watches like FitBit or Apple actually do stuff, self driving cars do actually drive, Elon Musk's submarine hyped as much as blockchain, seriously? Blockchain businesses have achieved practically nothing.
> it took almost 20 years for the underlying infrastructure to get mature enough to get mass consumer adoption.
I don't know if you were on the Internet in 1998. I was. The Web was useful, mature, and had tens of millions of paying customers in 1998. In contrast, all the people I have known to use Bitcoin and other cryptocurrencies only do it for speculation.
You bring up PayPal and list eBay as a "defunct also-ran." The only reason people started using PayPal was to shop on eBay, and the only way PayPal got anyone to start using them for payments was to bribe people with $20 referral bonuses, which they could only do due to their VC firehose of money, and a huge spambot campaign where they pestered eBay merchants with messages along the lines of "I'd like to bid, but I can only do PayPal." (see The PayPal Wars)
PayPal is a great historical lesson in explaining why BitCoin and other libertarian hash chain schemes will fail as a currency, because PayPal was founded on the same deluded libertarian fantasy:
"“PayPal will give citizens worldwide more direct control over their currencies than they ever had before,” Thiel predicted. “It will be nearly impossible for corrupt governments to steal wealth from their people through their old means because if they try the people will switch to dollars or pounds or yen, in effect dumping the worthless local currency for something more secure.”"
Bitcoin is for speculation. That's its use-case: it's fundamentally a financial system. It's made a few million people rich and several more million people poor, and started several thousand businesses. That's not a bad track record for something 9 years old; it beats out YCombinator (whose use-case is also "making people rich"), which is almost 14.
I've been on the web since 1994. I certainly found it useful in 1998, but the things it was useful for included:
1.) Looking up Geocities pages for my favorite bands.
2.) Reading rec.arts.sf.written.robert-jordan.
3.) Playing DragonRealms, an early MMORPG.
4.) Instant-messaging my friends.
5.) Earning money through AllAdvantage.com. Think I made about $40 from them off referral fees.
6.) Looking up information for school papers.
7.) Amusing myself with the HampsterDance.
Streaming video existed but was far too slow and glitchy to be worth watching. Amazon.com existed, but my parents refused to buy anything online. My sister was an avid user of Kozmo.com when she went to college, but then they went bankrupt a year later. MapQuest existed, but took too long to load and still required that you print out directions, since you couldn't exactly bring a computer in the car.
By contrast, I've spent over $5K at about 2 dozen different AirBnBs in the last 5 years (and stayed at a hotel...erm, twice, maybe?). I just booked a haircut online, after reading the Yelp reviews and looking up the location on Google Maps. I spent 15 minutes typing up this comment on Hacker News, which I guess is the spiritual successor to Usenet. I don't own a TV, but I watch a bunch of YouTube and my wife's an avid Netflix user. We get almost all our packages delivered via Amazon.
In terms of how much the Internet changed behavior, a lot more happened in the 10 years between 1999-2009 than the 10 years between 1989-1999, and arguably even more happened between 2009-2018 than 1999-2009.
hedera hashgraph papers and founder talks (you should find them on youtube) made me realize some real people were working on solving real world issues, and not just scam people.
