Joy stream appears to be a service which rewards people for hosting torrents. I could see this being used by a lot of people.
Are their any services that provide usage figures for any of these Dapps? I’d be curious to know how much they are used as I think Dapp usage is a good bellwether for utility token valuation.
I really want to see crypto currency move beyond just being used for speculation.
The Dai stable coin. Many different smart contracts are constantly working together to keep the token worth very close to 1 USD: https://coinmarketcap.com/currencies/dai/
The core mechanisms are enforced by smart contract, dai issuance comes from multiple entities, it provides (or aims to provide) a large number of users some utility (stable purchasing power, whether to hold or spend) - why is it not a dapp?
In general, it is better if the value of your money that you want to use to buy things does not fluctuate every minute like in the case of Bitcoin.
People are working on Dapps for insurance, lending, prediction markets. It is not practical to take out a loan that is denominated in a volatile currency. Also, If you want to bet on the next president in 2020 for example, it is not practical to make the bet using a volatile currency such as Bitcoin.
USD is not the ideal currency in terms of value stability. I know nothing about Dai, but if it works, its technology could be expanded to other, more material, more reliable assets than USD, and that would be great.
USD can't be sent over the wire without the approval of and fees paid to banking institutions, with which both parties must be previously related and approved by.
I assume because it allows you to trade in and out from crypto positions to something that tracks fiat.
This of course assumes that this coin can actually hold its value in the event of a market crash. I also assume it’s not backed by real dollars held in a bank but some kind of basket of other cryptoassets right?
It's currently backed by ETH but is moving towards multi-collateral assets. Today, they announced a partnership with Omisego [1], with one goal to allow OMG to be used as a type of collateral. There's also chatter about using DIGIX, which is another stablecoin pegged to the price of gold.
The mechanism by which they maintain stability is quite fascinating. From the whitepaper [2]:
> The Dai Target Price is used to determine the collateral-to-debt ratio of a CDP, and thus the Target Price represents the price at which Dai is backed by collateral in the long term. The Target Price is continuously adjusted according to the current Target Rate. Automatic Target Rate adjustments ensure that the Dai market price remains stabilized around the Target Price in the short term.
> When the market price of Dai is below the Target Price, the Target Rate increases. This causes the Target Price to increase at a higher rate, causing generation of Dai to become more expensive. This leads to CDP users covering their CDPs and leaving the ecosystem, causing the outstanding supply of Dai to decrease. At the same time, the increased Target Rate causes the capital gains from holding Dai to increase, leading to a corresponding increase in Dai demand. This combination of reduced supply and increased demand causes the Dai market price to increase, pushing it up towards the Target Price.
No it is not backed by real dollars in a central location. It's a kind of a derivative. The way it works is very interesting. Recently Andreessen Horowitz and others invested 12M into the project.
Anyone else a programmer/tech person that thinks blockchain is awful for storing information?
Centralized servers are extremely good at what they do. I feel like most of the time blockchain isnt needed unless things need to be decentrally verified.
I was considering doing my own 'cryptocurrency', but I decided a centralized server was better for doing the job at hand.
It seems like a really good way to store small pieces of information that aren't changed very often. Such as Name System Registry entries. It works really well for this type of use case, and name registries are good things to be distributed. Using an EVM based blockchain allows me as an engineer to get strong identity, authorization and storage guarantees for free, leaving me to focus on the logic and systems around how names are changed and what those names mean.
You might have had misconceptions about the blockchain, but you seem to have come to the correct conclusion. It is awful for storing information, and it's generally not meant for storing information. Obviously you can combine traditional servers and blockchain in a such way that the system is completely decentralized, such as Sia https://sia.tech/.
Patchwork looks great. But it's an old-school distributed/federated app in the vein of IRC or XMPP, right?
The definition of a "dApp" these days seems to require blockchain, either for storage or for a token ecosystem. This co-opting of the word "distributed" is unfortunate but probably as difficult to fix at this point as the misuse of "crypto".
Dapps mean apps on blockchain and consensus. Patchwork does not apply, otherwise one could mention "Torrents!" etc. You would be at least 20 years late to the party.
> Are their any services that provide usage figures for any of these Dapps?
The closest I've seen to this, eg. an Alexa.com/AppAnnie for Dapps, is https://dappradar.com.
It measures DAUs, transaction counts and daily/weekly tx value (in ETH) across many Ethereum smart contracts. It's not perfect but does provide a decent standardized view of some Dapp usage/traction.
One I came across recently that looks promising is joy stream:
