what about require instead of assert?

Good day everybody! I've installed the Ethereum Wallet and I am about 150 blocks away from having downloaded the whole blockchain. No matter my (many) restarts over the past few days (I'm mostly using geth --rpc --cache=4096 to do the syncing) it appears that the closer I get to the end of the blockchain the slower it gets. Is there a reason for this?

@emanuele3d Firstly, why are you using --rpc unless you intend to connect over http://localhost:8545? Secondly, your system clock is probably not synchronized.

Hello, I need one help with running a truffle migrate project. I have created a simple smart contract and compiled using truffle compile... now when I am running truffle migrate, it is throwing an error: Error: authentication needed: password or unlock. after further check, I found that my testrpc has only 1 account and it does not have any ether balance. But the tutorial says a testrpc provides 10 accounts with some ether balance. On top of that, now when I am running testrpc, I am getting new error Error: listen EADDRINUSE :::8545
can someone please help with above issue?

@phalexo To be honest I have no idea why I'm using --rpc apart from the fact that it seemed quicker than not using it, as described somewhere on the internet. Regarding the clock, my Win7 system always has the "Internet Time" feature activated, but was reading from time.windows.com. I have now set it to time.nist.gov, just in case, but I had never noticed a problem with the system clock. Are we talking about fractions of seconds off the mark causing this problem?

Admittedly now that I have relaunched geth without --rpc I don't really see much difference in speed. But Ethereum Wallet is telling me I am about 300 blocks from the end (out of 4+ millions) and it's downloading the chain structure (again? but why?).

I got the issue. It was because geth --rpc was still running on my machine. I stopped it and ran testrpc and it worked like charm. Apparently, they both use the same port to run (8545) and hence testrpc was not taking off... thx anyway

Hello guys. I fixed the "Throw" issues and now I'm facing problems with the follow error:
Variable is declared as a storage pointer. Use an explicit "storage" keyword to silence this warning.

@gabrielmoreira1975 Use string storage description; and see if that helps.
gabrielmoreira1975
@gabrielmoreira1975
@MidnightLightning Unfortunately no. Using string storage description; we got the follow error:
Expected identifier, got 'eth_compileSolidity'

what is difference between the "internal transfer" and "transfer" functions?
Brooks Boyd
@MidnightLightning
@gabrielmoreira1975 Hmmm, I see in your code line you've got a semicolon at the end of the line; is this part of the declaration of a class variable? If so, then the real issue is likely somewhere else; you've got another variable with the same name which is getting mixed up with this class-level one? If you show more of your code, we can probably help you out more.

I need instructions to run a very simple Ehtereum code .. how do I create the most basic contract and how do I run it ? can someone help me get started ?
Brooks Boyd
@MidnightLightning
@vin-wag Your best bet is to go through the sample exercises on https://www.ethereum.org/ to get started; those are some well-documented examples to start with.

I'm so close to downloading the Ethereum blockchain yet it stopped and I don't know what to do. I used the following code.
geth --syncmode "fast" --cache 1024

I'm also having problems downloading the whole blockchain. It is stopping/hanging very close to the end. So far I found no solution. But the saddest part for me is that I was evaluating if ethereum could be the platform for e-voting for my local community and with these problems I cannot recommend it, it's just too rough on the edges for average computer users (and even worse for older people) to deal with. =(
I will nevertheless try some development through the available frameworks and test nets..

@emanuele3d Even if you can't get your local node to sync up properly, that doesn't need to be a hindrance to keep you from using the Ethereum blockchain to create your own smart contracts. Using a tools like MetaMask, Remix, and MyEtherWallet, you can interact with the Ethereum network without needing to figure out how to run your own node.

hello,everybody
who can help me to solve a small problem?

i want to create a new contract with Ethereum,when i did the last process ,the fee could not be transacted,and i got a notice that you account can not do incoming transaction.How can I do then? please help me ! This is important to me.Thank you!
the notice is :Accounts are password protected keys that can hold Ether and Ethereum-based tokens. They can control contracts, but can't display incoming transactions.
phalexo
@phalexo
@panjian1969 The problem is with your understanding of English, not software.
panjian1969
@panjian1969

?
please direct me!my English is really limited
phalexo
@phalexo
The notice has nothing to do with any problems. It simply informs you that you would need a wallet to display transactions.

@panjian1969
wallet? Is my account a wallet?I have an account with 1.01 ether
phalexo
@phalexo
Accounts are not wallets, and wallets are not accounts.
panjian1969
@panjian1969
ooo
phalexo
@phalexo
A wallet manages 1 or more accounts (which are just public/private key pairs)
panjian1969
@panjian1969
but I downloaded Ethereum Wallet ! and I created a new contract there!
how can I get a wallet?
