Cryptocurrency works under the technology of blockchain. Managing to corrupt even the smallest part of this technology is considered to be hacking. The network of users persistently surveys these blockchain technologies. Due to this reason, it is quite hard to corrupt the system. However, in recent times hackers have managed to evolve their way of exploiting with the use of the 51% attack.

In this 51% attack, the hacker manages to obtain power over 50% of the hashing function. This power allows the hacker to tamper with the information stored in the blockchain. This further takes place by using the digital token several times. In this method, the hacker replicates the file. In a 51% attack, the hacker gets the ability to conduct a double spend. Double spend wipes out the record of transactions and hence, the tokens become suitable for reuse.

  • It is of utmost importance to control every wallet with efficiency. Hence, the users should always store the majority of the collections in the multi-sig cold storage wallet. Storing them in hot wallets makes them more prone to hacking.
  • It is always advisable to use different addresses for all the wallets. In this manner, hacking one of the addresses will not sacrifice the rest of them.
  • The user should always turn off the phishing links. It is because of the reason that these cracking mails tend to invade personal information for hacking purposes.
