Topic: How can anyone block coins or transaction in blockchain ?! (Read 292 times)

 It will be a worse scenario.

I have never find one and what I always see in altcoin team is people who enrich their pocket. What altcoin are you saying in particular?

I don't forget. What I am saying is that ICO was not introduced by ETH (Mastercoin was the first project to ever held ICO in July2013).

There is a difference between not delivering on some promise and not having the basic mandatory characteristics. Imagine if you bought a car and it didn't have any wheels or didn't run.

There are some altcoins that did the same thing as Satoshi did and also introduced new things.

You seem to have forgotten that ETH itself is premined altcoin that had an ICO!

If you are talking about bitcoin or another decentralized token then it's impossible to block any address. This is what decentralization is all about. There is possible in theory "attack 51%" - but someone will need to have min 51% of all network to have opportunity of manipulation in blockchain, and at this point of development it is impossible for Bitcoin.

I understand the ETH team mess up big time by not delivering to their promise but it what it is people make promises and never keep and it just like how we see it in the politician when they are campaign they make empty promises but when they win the vote story change.
However, we need to understand that everything will never be perfect and if Satoshi don't leave the Bitcoin duties to the communities I'm sure some individual will still complain that he's not doing the right thing.

It not proper to compare Bitcoin with my crypto because Satoshi create the project in a selfless way and no altcoin team can do that  but respect the project team (ETH) for introducing something new that's what one of the thing I usually look for a new project.


Agreed the project and what we're seeing is just a change of name and platform but ETH never introduced ICO, it only introduce smart contract and dApp. If boy of 19years smoke narcotics we can't blame the bar man for because it was not public advertise and it the boy that requested for it on his own.
With that been said, if Satoshi don't want the existence of altcoin he won't have make the Bitcoin source code available to the public for people to emulate it.

Kinda agree with you. ICO, IEO, STO, DeFi are rebranded names for different trends in different years. Instinct is the same. Built for scammers to steal fiat and bitcoin from greed, naive investors.

DeFi, is it different than Staking/ masternode trend in 2018? Many people lost money from Staking/ masternodes and now they forgot pass losses to join DeFi.

Swap on DeFi is to help those operators collect as much money from fees as possible. Who cares the value of tokens on their DeFi? Even they don't care about it.

They are not 2, there is only 1 and they keep changing the name while doing the same exact thing: ICO, IEO, STO, DeFi, NFT,...
They create a useless token that has absolutely no connection to anything including the business and people who create it and sell it to people to raise funds. That's all.

It is not and for a very simple reason: there is no connection between the token and the business.
Let's say you are running a gambling site and create a token to raise funds and expand your business. If your business fails and you have to shut it down the token can still be pumped and have increasing value. Conversely if your business thrives and you make millions the token can get  dumped and reach 0.
So what did these "share holders" gain by buying that ICO token? Nothing! They could have bought any other pump and dump coin.

The "smart contract" smartness and contractual characteristics start and stop at the fund-raising stage.

The reason for copycats is simply because ICO scam was successful and both the ICO scammers and the platform owners (aka ETH foundation holding the 72 million premine) make millions. So obviously other people want in and to do that they create their own "smart contract" platform.
Funny thing is that some of these alternatives are so much better and safer than Ethereum even though people who claim "smart contracts" are interesting ignore them just because they aren't as pumped as ETH is!

Well, each time I ask someone who makes this statement to show me an actual application that is working in real world they either can't or show me the "token swap" projects where you can trade one ICO token for another ICO token! So I don't see any potential there.

Exactly. Bitcoin is good because what it promised to deliver was useful and solved some actual problem in the actual world and most importantly it delivered on that promise.

There is some truth here, but I think you are exaggerating a bit.

For now, the 2 main implementations of ETH are DeFi and ICO, which failed imo.

I have always said that DeFi are basically useless (as you need to pay 100% collateral at least to be *somewhat* secure), and a 100% collateral loan is useless and has no application in the real world. Why would I lend 1 ETH to borrow 1 ETH back? lol Just for speculating purposes...

About ICO, they are an interesting concept. Smartcontracts controlling the fund raising, receiving Tokens back when you transfer eth and so on... But I believe all that could be done in Bitcoin. But they also failed imo as the space was mostly used by scammers.

However, Eth potential is huge and much bigger than those implementations. Just look at so many ETh copy-cats we have: ADA, waves, NEO, BNB, and probably a lot more (i don't know much about this shitcoin world lol).

The idea of running decentralized Apps (dApps), which are applications that once running cannot be stopped by anyone, is very interesting and has a lot of potential. Once we have (and if we have) oracles running delivering real world data into smartcontracts we will have some nice implementations.

But, for that to work, we need many things: Oracles, PoS,  real scalability and real decentralization. I think ETH is now far from that... I still hold a few ETH, let's see where it will go in the next 5 years or so.

For now, Bitcoin is certainly the best bet. Bitcoin was able to do what is in the whitepaper almost 12 years ago: Censorship resistant, decentralized, open, borderless, cannot be shut down, etc.
People cry about slow/expensive transactions, but it is way better than ETH for example.

ETH is not just bad it is the worst because it doesn't have the fundamental characteristics of a cryptocurrency and it was never capable of delivering any of the promises it made: decentralization, immutability, utility, security, cheapness,... none of them exist in ethereum!

You say "smart contracts" but have you ever seen even a single one that has any utility in real world? Of course not because the only usage of Ethereum and its smart contracts is to create useless tokens to raise funds and scam people. So it remains the most useless cryptocurrency of all times.

Compare that with bitcoin or even a useless altcoin such as Doge for example, they solve a problem in real world. People can use bitcoin to transfer money in a decentralized way that noone can censor. They tried calling ETH a currency when it was failing back in 2017 but since its fees shot up higher than bitcoin's that scheme also failed.

2 most likely experienced by the OP:
- The OP entrusts the scammer to manage the masternode.
- there is a technical error from the masternode hosting software that the OP uses so that the balance is not credited. I see there are several hosting providers if ESK what the OP means is this. https://cryptotophost.com/coin/esk/

The issue is really weird, you mention that you already verify the transaction in the blockchain and it's there but the coins aren't in the wallet. That could mean 2 things, the node where you are waiting to receive the coins isn't updated or you have wrong char on the addy, sometimes people write address by hand and confuse the l with the I, let me put them together to show you lI... one it's L and the other its I.

Transactions can't be blocked just like that, so, my advice is... If you want to experiment use known coins, because if you use weird coins like ESK maybe it could be a target of the 51% attack.

I understand the hype base of the altcoin market make it hard for investors to understand the altcoin that performs genuinely well in the market but if we are talking about altcoin that included ETH which was another project that introduced new features to the crypto sphere (through the smart contract/dApp scheme) and I consider it not to be among the terrible coins you said.

With bitcoin address in non custodial wallet and bitcoin transaction, you are your own bank and no one in this world and in the universe can block your address, coins or transactions. With alternate cryptocurrencies and their transactions, it is possible.

PSA: Most Stablecoins Can Be Frozen, Even in Your Own Wallets
List of banned addresses:
USDT: https://duneanalytics.com/phabc/usdt---banned-addresses
USDC: https://duneanalytics.com/phabc/usdc-banned-addresses

Beginners should stay away from all the altcoins not just masternode coins because almost all of them are useless specifically the top 20 altcoins that are the most hyped up and most terrible coins created for pump and dumps.

Stay away from low value master node coin which could later scam investors have nothing to do with stay away from all master node project but due to the fact almost all master node coins go from grace to grass, the best way to advice a newbie is to stay away from master node project because newbies will not understand the features the look out for before choosing a master node base project.

Sniffing a transaction (which implies a malicious 3rd party - not the owner of the network) is generally not possible. Even not with centralized coins like XRP.
Generally, an owner of the network can always block transactions. That's the same with bitcoin. If (and that's a really big if) all Miner would collaborate, they can block single transactions.

With BTC that's obviously way less probable than with a centralized coin like XRP, although theoretically still possible.

technically it depends on the cryptocurrency that we are talking about. if it were centralized then it is very easily possible just like it is possible to block an a PayPal account. for example government coins such as Petro or centralized altcoins like XRP are in full control of their network. at any time they can block or even take any coins they want.

i have never heard the name of the coin OP has problems with though (ESK) but this is unlikely to be the case here. i suggest directly asking in the announcement topic of that coin or finding any other medium to communicate directly with the creators.

This is utter BS and the guy who had fetch you this information is either a scammer or a great con artist

Is the destination wallet yours? Is it someone elses?

It honestly sounds like someone is trying to scam you for more money by claiming that they didn't receive the funds you sent... and then making up a bullshit story that your transaction was "blocked".

Or, if it's your wallet, it sounds like your wallet simply isn't synced properly and is not displaying the transaction.

I don't know from where you got that idea, but I can assert that it's impossible. Any currency developed on Blockchain is irreversible or permanently delayed (blocked).
You are referring to a piece of junk money - ESK, I recommend that you ignore it immediately, it is not a blockchain currency, it is fake or a scam. Take your time for better money  

Edit: Having read the OP more closely, you don't need to worry if someone knows your wallet address. You can put it anywhere, you can show it to anyone, as long as you keep your private key secret. Your money will not have any problems. No one can prevent transactions to your address

That's correct.



That's not possible.


I would recommend you to stay away from such low value coins - especially master node nonsense.
The majority of them (probably 95%+) are a pure scam.

There are funnier ways to lose money, no need to invest in scam projects.

It's probably due to  security vulnerability on the coin you were working on. I would advise you to have a couple of experts in blockchain field help you set up a masternode and also do some security audits to avoid such attacks. Just because yours got attacked doesn't mean all the blockchain techs and the coins run by them are flawed

Based on your description, I am guessing it was 51% attack. That one attack I know where someone can block transactions by invalidating them and it's easy to carry out on small networks without using many resources unlike Bitcoin. There are ways of avoiding such attacks.

I wanted to make a masternode, truth is that I'm quite new at this kind of stuff. It was ESK coin. I accepted the idea that the coins are probably lost, it was just strange that someone can do this without any other additional information from my part. I have never given away any data, just the public address. This is why it was so strange

Your problem is not clear, are you trying to say someone stopped your transaction? To me it seems your transaction has not yet been confirmed can you share the Transaction ID
Nobody can block your coins.

Who threatened you, can you shared details?
Anybody can have anyone's public addresses and won't be able to access the funds in your account. However, if you give them your private key, then they can be able to steal your coins. 

A public address is like a bank account number, anybody can see it but can't access the funds of the account unless if they have the credentials(private Key, seed phrases etc)

Someone if probably lying to you so that they can make you give them your Private Keys

In Bitcoin network an address or output or coins or whatever cannot be blocked.
I don't know what shitcoin you are using, maybe you could tell us more....... But it is highly unlikely that your coins are "blocked" by this hacker.

Hi guys, sorry for writing here, but I do not know where else to post this question.
I believe I was hacked somehow, but I don't know how. This is not about bitcoin, it's about an another coin. Someone has blocked my coins in the blockchain or stole them, I really don't know, the interesting thing is that in the blockchain explorer, the transaction is there, it is confirmed, the receiving address is correct, but the coins never reached the destination wallet. I was threatened with this process of blocking my coins, because I didn't wanted to give access to my computer. The other person knew only my wallet public address. How can someone do this? How is this possible? If this can be done, than it might be a real concern to everyone. This means that not even the public addresses are safe? I don't understand. I thought that someone can steal your coins only if they hack the wallet, have the private key, the wallet backup and the password. I never thought that someone can just block coins in the blockchain or sniff a transaction somehow to end up with the coins you send. Is there any possibility to see how the coins, if they still exist, can be unblocked? Is there something that can be done?
I learned my lesson, please be aware that these things can happen and take care in the future. Thank you in advance.
