As mentioned, '51% attacks' could be a threat to Blockchain. But with the rise of many Proof of Stake blockchains, this happens to be less dangerous than before. With a PoS, the attacker would need to obtain 51% of the cryptocurrency to carry out a 51% attack. The proof of stake avoids this ‘tragedy’ by making it disadvantageous for a miner with a 51% stake in a cryptocurrency to attack the network.
I am also very impressed by this information:
This news shows us how far blockchain adoption has gone. Teaming up with the government is a huge step! Let's hope these kinds of partnerships will make blockchain become more friendly to our daily use, and when speaking of blockchain, people will have more things to discuss than just cryptocurrency.
