The 30s block time for Tezfin is indeed a good enough time to not think about it. This is because it is a fast and secure way to process transactions, and it ensures that the transactions are processed quickly and securely. By having a shorter block time, it also reduces the chances of double spending, which is an important factor in maintaining the integrity of the network. In addition, the shorter block time also allows for faster confirmation of transactions, which is important for users who need to be able to access their funds quickly.
However, it is important to note that having a shorter block time also means that there is more of a chance for malicious actors to try to exploit the system. Therefore, it is important to be vigilant and aware of any potential threats and to make sure that the network is secure. This is why Tezfin has a Discord, so that users can keep up to date with the latest announcements and developments and be able to stay informed of any potential threats. By being aware of the latest developments, users can take the necessary steps to protect their funds and ensure that their transactions are secure.
