Blockchain is a digitized public ledger of all cryptocurrency transaction. It allows market participants to keep track of digital currency transactions without central recordkeeping.
In a blockchain, there is a countless blocks that is connected to each other like a chain. It has a complete information about different user addresses that we usually used to collect tokens/coins and report balances right from the block to the most recently completed block.
Is there a possibility that ethereum-blockchain be hacked?

There is nothing online that cannot be hacked, just because it has not been hacked yet does not mean that it is impossible to hack. There are a lot of projects in the past that the creators marketed as unhackable, what happen is that a lot of them got hacked. It just takes a really well organized group of hackers with enough funds to focus their energy on hacking it

I don't think that Ethereum itself is vulnerable to being hacked. Countless independent parties have audited the blockchain and the smart contracts without reporting vulnerabilities.

Are you understand how work encryption? In the blockchain private keys not stored. And without this keys access to wallet is closed! No chances. But yes all wallets are clear for view. Try to learn more base knowledge about blockchain

That's actually really great news.

People are always afraid of hackers regardless of the situation and that piece of news is a great relief

Hi! thanks for the opinion.. Does it mean they cannot access because of encryption? Maybe the security hackers work on this..

Prior to this, there was an attempt to hack, so the Ether was divided into two blockchain. Now the developers of Ether have taken into account all the mistakes, so I think that you can be calm about this.

AFAIK, it can be slow down but it can't be hacked.

This is the strength and weakness of blockchain.

The hackers can hack Everything. We saw many incidents about some significant hacking. Like someone cut millions of dollars by cutting a bank or any news like this. But as you mentioned blockchain has infinity blocks, that's why it is very tough to get ethereum blockchain hacked. Maybe it's impossible too.

I think it is possible but base on its security issues this past years we could observe the smooth run of eth and blockchain without having  large issues of hacking that could be alarming. But we can't be so sure for now but I trust cryptomarket.

The only possible thing to do 51% attack to the ethereum blockchain but it requires a lot of hash power and i doubt if that can become a real thing. PoW is using miner as the main pegged of the network to validate the transaction.
The collusions between the miners can create 51% attack and you should read more about 51% attack. I remember this time asic has been dominating all of the PoW crypto.

any blockchain can not be hacked, but if the overload of blockchain transactions can get stuck and this once happens when a cat game or cryptokitties is launched. maybe you mean is a wallet provider, like myetherwallet?

we dont know what hackers capable of, but i dont hear any news that ethereum blockchain has been hacked for the past years, maybe its impossible to hack. or maybe they are now trying to hack.just like bitcoin i dont also hear a news in the past years that it has been hack. Well we just dont know when will it happen or maybe it wont happen. the security of a blockchain is very tight so its impossible to hack.but no one is perfect even in computer is not perfect.

I think the blockchain is relatively safe for the current Internet protection. First, if insecure funds have fled. Second, only quantum computers can do this. Then in addition to these two dangerous places should be Trojans stealing personal privacy. That is, hackers use the same login system as you. Because they have your information. However, if there is no virus on your phone or computer, the crypto currency is absolutely safe.

I think that certainly it can, but for this, the code should be vulnerable, if this vulnerability has not been found yet, then it probably is not there, for this reason the Ethereum develops so slowly, because the team needs to make sure that their code is perfect and that people will not lose their money because of some small idiotic mistake.

The compromise of Ethereum addresses, as well as many other blockboys, is possible because of poor-quality software in the event that the generation of random numbers during the creation of a signature ceases to be accidental. The risk is insignificant, it is recommended to use only proven software.

I dont think any such thing is possible. Becuse Eth has a highly efficient security system and it is not so easy to break it. So I thing you don't need tp worry about that.

Different ways the hacker looks for loopholes to make a profit, including hacking the ethereum wallet. But, I think ethereum has good security, provided you are careful and always keep your private key.

It seems to me that you can hack anything, but how much time, effort and knowledge will it take? I don't mean that the Ethereum blockchain is poorly protected. On the contrary very, very reliable

No, it can't be hacked but an etherum private key can be hacked if the holder is careless with it, it think ethereum network has passed level of hacking. I learnt they have 80 developers or thereabout.

It is possible. There is nothing on the web that can't be hacked, on the grounds that it has not been hacked yet does not imply that it is difficult to hack. There are a great deal of activities in the past that the makers showcased as unhackable, what happen is that a considerable measure of them got hacked. It just takes an extremely efficient gathering of programmers with enough finances to concentrate their vitality on hacking it.

anything can br hacked, but if you are talking about Ethereum-Blockchain, which is not child's play, because they are most advanced among them all. if we learn a bit more about how Blockchain works, then we get to know it's kinda impossible.

I think Ethereum blockchain is not easy to hack as it is very nicely secured. Without this there are a lot of investors in the market those who are trusting it and having a safe transactions.

From my perspective i think it’s hard for hacker to hack ethereum and blockchain. Because they use high level of securities. But its true ethereum and blockchain are 100%secure.

Well, I don't think so.There're so many crypto currencies have evolved and all od them are encrypted. Ethereum is one of them which works with smart contacts and it keeps things confidential.

Though the technology changes day by day so many scam and hackers are also creating new problem and it may bring huge loss based on this ETH can suffer this because they don’t have any reserve data server on everything is online based so it may create some problem and avoid this problem invest in BTC.

until this happened. but in the future, we cannot guarantee that hackers will not be able to crack.
