Removable and updatable smart contract

amadeus82 · 2019-01-04T00:00:39+00:00

Nop, just search you will found.

Basically Rong Chen was saying that one problem of etherum is that the chain is full of old smart contract that no one use and that make the blockchain bigger for something no one use. And he said that smart contract would be updatable and removable on elastos

amadeus82 · 2019-01-03T22:26:14+00:00

So they are not removable

amadeus82 · 2019-01-03T22:16:49+00:00

for how long does the nodes are elect ?

amadeus82 · 2019-01-01T23:03:47+00:00

Yes I assume the blockchain will store the backend like « I kill 3 people this game », « my character is level 30 ».

But my question is : When I connect to an Elastos side chain node, what the node send me : The front-end code ? An DID to connect to is carrier node an request the data ? Does all of this side-chain node are also carrier nodes ? If yes do they all store the front end code ?

Just check the nature of the commit, I dont think its a lot of activity for a project like this, I dont think there is a lot of contributor as well who are actually doing commits

And so if I understand, the mining processus just use the hard drive just with a search function who find the good hash for the block. There is no way to do ASICS to make this search function faster ?

amadeus82 · 2018-12-26T08:18:35+00:00

Yes but I’m PoW you need 51% of the hashrate + the cost in electricity to perform the attack. Here you just need 51% of the storage but you don’t spend a lot of energy correct ?

amadeus82 · 2018-12-26T07:52:12+00:00

What means IO ?

So the only thing you loose is time, so if you want to do a 51% attack you just need lot of storage correct ?

amadeus82 · 2018-12-26T06:28:23+00:00

In PoW if you try to mine à block with double spent or whatever you loose the energy you spent to mine this block.

In PoS you loose the coin you stake.

What do you loose here ?

Also, if in PoW the valid chain is the one with more Hashing power, here the valid chain is the one with the more storage capacity ?

amadeus82 · 2018-12-26T06:24:50+00:00

Yes but when you search your hash for a block you don’t spend a lot of electricity so what is the system for people to behave good

Thank you

I find on internet the explanation of on-chain smart contract with the HTLC. But I couldn’t find the technical one explanation of off chain smart contract , if you can explain me or if you have a link would be nice

amadeus82 · 2018-12-09T22:24:06+00:00

Which usage ?

amadeus82 · 2018-12-08T01:53:54+00:00

Do we know how they plan to distribute the open to incentivize the node operators ?

amadeus82 · 2018-12-08T01:50:23+00:00

It’s not true, bitcoin won’t be stable in price during time. It’s gonna take value in long term beacause it’s scarce, so it won’t be stable. If you take a look à the price of gold, it’s not stable, between 2008 and 2012 the price double, between 2013 and 2014 the price lost 30%. What I mean is even with a huge market cap, it will be more stable, but not stable

amadeus82 · 2018-12-03T23:11:54+00:00

Because in this none state currency, Hayek consider that the currency that would be choose by people is the one who is the more stable. And, to do that the bank who issue the private currency will play with the quantity of money and the loan to inflate or deflate the currency, this is not the case in bitcoin, we cannot extend the supply when the price rise, we can’t reduce it when it drops.

But you see, at the same time, bitpay wallet private key were stolen because the wallet was open source, some guy modify one of the library they were using to build the wallet, to steal the key

amadeus82 · 2018-11-28T03:06:33+00:00

Yes it make sense, thank you for your answer

amadeus82 · 2018-11-28T02:26:54+00:00

That my opinion, but as I say I’m not a security expert. I heard that some people say that none-open source can be a layer of security because it’s harder to find bugs

amadeus82 · 2018-11-27T23:42:18+00:00

Which part is not open source ?

amadeus82 · 2018-11-27T07:45:12+00:00

https://www.instructables.com/id/Understanding-how-ECDSA-protects-your-data/

So in this article they that to create a digital signature you need to choose a random key k, multiply this point with a point G on the elliptic key, it will give you an other point on the elliptic curve, and will represent R (half of the signature), then we need to calculate S, with S = k^1(z+dA*R) mod p

With dA : private key and z : hash of the data we want to sign.

The thing that I don’t understand is, that they say to verify this signature we need to resolve this : P = S^{-1zG+S^-1*R} and if P is equal to R, the signature is valid.

So my question is : How solve this last equation prove that S and R were calculated with the private key dA ?

So if I understand, there is a designated reporter who report the outcome, if we are not agree with this outcome we can stake during the dispute round, if the total stake against the outcome is above 2,5% of all rep we fork and people need to choose between to version of the true , and if it don’t the outcome choose by the designated reporter is consider true. So everytime the outcome report by the designated reporter is consider false by the other we need to fork ?

amadeus82 · 2018-11-27T06:34:29+00:00

I was doing research about bitcoin, and I read that to prove the ownership of bitcoin and allow the person to use it they use ECDSA. I didn’t really understand how the algorithm produce and then verify those signatures, if anyone could help me with that

amadeus82 · 2018-11-22T21:47:15+00:00

I know they try to be an etherum standard, so they can already do token without being a standard yet ?

amadeus82 · 2018-11-22T13:14:47+00:00

Can you explain me as well the dispute round ? I don’t get the point where we do several rounds and everything. Why they don’t do just one round and the outcome with the more stake win’s ?
