ENS is a great example of a centralised system plus its only about eth based names, no application other than just a method by to collect money by the platform for offering services that are only about the platform and work in the platform.

Yes, they really took time to fake so. I encourage engineers to try and build a decentralised app on it.

>happens to have

Sorry but ethereum has no use case, nor is technically ethereum's architecture makes distributed computation possible or even is decentralised. There is not one single dapp that is decentralised and working.

Crypto would enable inbuilt content use payment system if the user wants to pay, and reap additional benefits - freemium model

Industries wont be monopolized cause forking and launching decentralised code would be free and instant.

You made such a long comment and could not name one thing that ethereum can do but bitcoin cannot. People using that decentralised exchange have either lost money during the ethereum forks (or haven't because oasisdex is not really decentralised if you look closer?)

>Ether is similar but at least has lower transaction costs

Myth. Do the math. Ethereum is much more expensive at similar parameters.

> transaction didn't burn thousands of dollars of electricity to verify it

If a transaction does not do this, it can be guaranteed to be insecure.

>Faster block times means she'll get her coffee sooner

Maybe. Or maybe the merchant doesn't get paid for coffee at all (because faster blocktime means more orphans)!

>Bob exchanges currency B for currency A with Alice. Alice now holds some currency B

There is no reason for Alice to want B, a less secure money than A which they already hold. If Alice were perfect mathematician, this exchange would never occur.

And introduce multiple other problems instead. There is no PoS system existing that is proven to be secure.

Ethereum's ecosystem cannot optimize for running dapps because the true value of its token is dynamically determined byt he blockchain network, for whatever value the minimum of its token provides. For eg, a gas is worth whatever the world wants to pay for it to use it as a unit of calculation on the world computer. To accurately measure the effort spent by the network to ensure the unit value of its token , we need a DMMS algorithm(as described in the sidechains paper) & which is nothing but a proof-of-work blockchain.

Each primitive operation needs its own blockchain for its value to be determined accurately. When multiple token are implemented over a single blockchain, for eg colored/custom coins, it cannot accurately measure the value of a unit.

In case of functional language, one could perhaps imagine a lisp blockchain with paul graham's 7 primitives implemented as an opcode (stack based interpretor is irrelevant), which would be turing complete but will suffer from the problem of determining the true value of each opcode; the cheapest one will always be abused as evident on ethereum (suicide function's cheapness was spammed).

> Ethereum offers a lot that Bitcoin does not

Myth. There is not even a single thing you can do with ethereum that you cannot with bitcoin. OTOH, you can do money with bitcoin, but you can't do it on ethereum because neither is it a true blockchain nor is it immutable ledger or decentralised either.

There is not a single use-case that this code can achieve, which you couldn't before the invention of bitcoin.

Blockchains are just linked lists; without proof-of-work its useless.

Sorry but this comic is neither simple nor accurate.

Firstly, recording the account of sahti is the only function of the ledger, which supposedly is a subset of a record of everyone's deeds' including the elves. Secondly then, fee analysis has shown that blockchains are a poor store of data and should not be used as a database since other mechanisms are far more efficient and cheaper.

No the payment provider doesn't trust you; you gave them your identity and perhaps more as collateral. My point was that even if one wants to use a decentralized system we do not need the security that bitcoin's mining provides because for small amount we have other networks.

There are scaling solutions like lightning network being built and the blocks are not full. Also for a cup of coffee you don't need so much security so go use litecoin or something, why not.

A note is clearly a proof-of-work currency concept. As stated, it takes months of work on expensive hardware. Anyone with better/more equipment can beat them but it requires an investment in a field where they have a huge headstart.

Ring Sigs are coming to bitcoin too.

You are right but it's the other way around. Being cute brings about domestication in an animal. Dogs are just more common because they were wolves 15000 years ago and stuck around groups of human hunters for leftover hunt. In return they acted as protection since others animals didn't come close, whereas humans were able to control them with fire. So humans domesticated the cute ones.

How was this not possible earlier?

> "which can't be secretly forged"

Not possible without proof-of-work

The world very soon is going to be the opposite of it, where you just release software and wait. An anonymous person launches a company without any capital, registration, employees, marketing, sales, which is ipo from day 1 and the founder is a billionaire just by releasing a piece of code. With blockchains it is possible to do so.

Private/Federated blockchains are just applied cryptography, which is not the same as the technology behind bitcoin; blockchain & proof-of-work.

There were around 40 cryptocurrency exchanges till early 2013, which were studied for causes of their failure. http://tylermoore.ens.utulsa.edu/fc13.pdf

If the govt changes monetary policy, your held dollars change definition; if bitcoin devs do anything my bitcoins remain as per the definition i agreed to. I can choose to move to that new currency or not.

70gb in 7 years.. including cryptographic witness which is soon going to be segreted..

Each of these use cases can be done with bitcoin. Pick any and I'll tell you how to do it if you couldn't figure it out.

No this is not crowdfunding over blockchains. This is just someone putting up an address to collect money and issuing homemade tokens.

Interestingly, that someone is the company being funded (slock.it).

There are non-smartContract program that run on blockchain. That is not what a smart contract is.
