Bitcoin Gold launch party spoiled by cyber-attack and plummeting value
Where blockchains have consensus rules based on a simple majority, there is a risk that malign actors will act together to influence the outcomes of the system. Understand how Facebook leveraged specific aspects of blockchain technology to launch a new cyrptocurrency called Libra, and its potential impact on the banking and finance sector.
Ethereum briefly tried this validation method but, due to forking issues, reverted back to Proof of Work. It is expected to introduce a revised Proof of Stake validation system in There is a risk that a participant with, for example, one bitcoin can spend it twice and fraudulently receive goods to the value of two bitcoins before one of the providers of goods or services realises that the money has already been spent. But this is, in fact, an issue with any system of electronic money, and is one of the principal reasons behind clearing and settlement systems in traditional currency systems.

Bitcoin Gold Developers Fend Off 51% Attack
Double spending refers to a transaction that uses the same input as another transaction that has already been validated on the network, meaning the user can spend the same digital asset more than once. Bitcoin Gold differs from Bitcoin in its mining method. Attackers mined the double-spent blocks on both days through the same address, pointing to the same attacker or group. It was likely easier for attackers to gain control of the majority of the hashing power because the protocol is not adequately decentralised. This occurs when network participation is low — either because a coin has declined in popularity or use — or when a centralised cluster of node operators holds the majority of the hashing power.
Bitcoin Gold devs say they stopped an ‘extremely long’ block reorganization attack
Version 0. The attack appears well-funded, as the perpetrators mined the Equihash-based cryptocurrency for almost two weeks with more than half of its entire hash power. However, unless their main goal was to expose the insufficient network security of the Bitcoin Gold protocol, their effort has failed. The organization recommends that users update their BTG Core full nodes in order to prevent any potential digital asset losses. In their official announcement, Bitcoin Gold developers explained to users how to step-by-step transition to the new version manually. They also suggested other ways for people to see if they are on the honest chain, one of which is by directly running a written command on the bgold-cli console. Apart from the instructions, the developer team posted emergency information about the earlier attack and reassured users that the updated code has automatically rejected the foreign chain. They also noted that, in the new version, a specific honest block was checkpointed so the attack could be prevented. The attacker mined their secret chain for nearly 10 days, renting power from NiceHash to do so.
Bitcoin Gold suffers 51% attack with $72,000 stolen
Such an attack allows an attacker to modify the transactions or prevent new transactions from getting confirmations, and even reverse transactions, leading to double-spending. Both of these reorgs contained double-spends. Based on Nicehash market price data for Zhash, the estimated cost of generating each reorg is at around 0. A fourteen or fifteen block reorg thus would have evaded both of the exchange's escrow periods.

As a digital currency or cryptocurrency, Bitcoin operates without a central bank or single administrator. Bitcoins are not issued or backed by any governments or banks, and Bitcoin is not considered to be legal tender, although they do have status as an acknowledged transfer of value in some jurisdictions. Rather than composing a physical currency, Bitcoins are pieces of code that can be sent and received across a kind of distributed ledger network called a blockchain. Transactions on the Bitcoin network are confirmed by a network of computers or nodes that solve a series of complex equations. This process is called mining.

Bitcoin Gold Hack Shows 51% Attack Is Real
One of the key strengths of the Bitcoin and its underlying blockchain technology is the distributed nature of building and verifying data. The decentralized work of the nodes ensures that the protocol rules are being followed and that all network participants agree on the current state of the blockchain. This means that the majority of nodes need to regularly reach consensus in regards to the process of mining, to the version of the software being used, to the validity of transactions, and so forth.
Suhyeon Lee, Seungjoo Kim. For this reason, the Proof-of-Stake PoS algorithm, which already has advantages of energy efficiency and throughput, is attracting attention as an alternative to the PoW algorithm. In this paper, we propose a predatory, destructive attack on PoS cryptocurrencies. The attacker destroys the PoS cryptocurrency system. Our findings are an example to show that the conventional myth that "a destructive attack that destroys the blockchain ecosystem totally will not occur because it is fundamentally unprofitable to the attacker itself"may be wrong.
Bitcoin Gold has been an interesting social experiment. This hard fork of Bitcoin had some high ambitions at first. Several months down the line, it seems things look a lot worse for wear. With one individual controlling most of the network, the ecosystem is facing a serious threat. Solving this matter has proven to be rather difficult. In the world of cryptocurrency, several key issues can affect any network.
Its most striking features compared to other digital money predecessors were its cryptography and verification process. Without these, Bitcoin would be nothing more than a string of code anyone could copy and paste -- which would quickly break down trust. But its novel process for confirming transactions, called proof of work, also has its drawbacks. So how concerned should you be?
Of course. It was with me too. Let's discuss this issue. Here or at PM.
Nothing serious, I think.
I, sorry, but this variant certainly does not suit me.
Yes, really. All above told the truth.
I have a CGI character :)
