The blockchain concept for dark forest was recently promoted by Ethereum, and primarily works robots that will copy any pending profitable transactions for delivery.
The robots can assess whether a particular transaction just entered into the mempool can be duplicated and will immediately fill their own version with a much higher gas charge, effectively ensuring that they are the first to require it. The term “Dark Forest” is inspired by a science fiction novel and refers to a place where discovery means immediate death – or in this case loss of money.
In Ethereum, this usually happens with public smart contracts that control money for a reason. Dan Robinson from Paradigm Capital showed such a case where money was incorrectly sent to a contract address. These types of robots also contributed to Bancor’s vulnerability plan for June.
Bitcoin (BTC) does not contain promising smart contracts, but a post from BitMEX Research highlights how a similar event occurs when a person uses their brain wallets.
Cerebral Wallet is the term for a private key that is stored only as a memory in the human brain, which does not mean any physical backups. This approach is usually not recommended because it is not ideal to rely on human memory to store a complex alphanumeric string.
A potential solution to this problem is to make a wallet from an easy to remember sentence. This is what analysts have done by creating the original sentence from excerpts from popular literary works, including the Bitcoin White Paper.
Unfortunately, the BTC deposited in these wallets was in some cases taken away even before the transaction was confirmed for financing. This was the case with simple opening words like “Call Me Ismail” from “Moby Dick” by Herman Melville. Other longer, more complex excerpts were still circulating throughout the day, and the Bitcoin White Paper “The Network Is Strong in Its Unstructured Simplicity” lasted the longest.
Analysts have concluded that headlines created from these complex but common key words are completely vulnerable and are constantly monitored.
As Cointelegraph previously reported, blockchain makes it difficult to use any password-based generation mechanism. On traditional platforms, passwords are largely protected by being stored in a secret database. Attackers have to interact with it to guess guesses, but the server usually issues a price discount. In addition, it is already several times slower to have to host an Internet request for guessing than to rush through locally stored collections.
Alternatively, private keys with blockchain can be generated in advance from massive dictionary databases, making attackers effective owners of these addresses. There are ways to reduce these vulnerabilities with salt – random pieces of data have been added to get rid of brute force attempts. But the basic problem with brain barriers is that any address that is robust enough will be difficult to remember reliably.
There are many stories of people losing BTC due to forgetting the private key they had stored in their brains, with a remarkable loss of $ 13 million recorded in 2019, although some believe it is false. Ethereum has probably experienced the same brutal private key impact that millions of dollars in Ether (ETH) have been reported stolen in the past.
