There are no statements in the wp regarding security of lina core other than there will be a security audit. This should be one of the top priorities for obvious reasons.
They mentioned Reputation management in their whitepaper meaning that their will be security in their core because they wanted their reputation to be clean and trusted in order for their project to work and be known by every internet user. Maybe their busy highlighting their project in different country that's why they are not here to answers all of the questions here. I still have high hopes for this project to shoot up.
My concern is actually that crypto currencies can be hacked. If lina is creating its own network for the tokens, they should take standard security measures.
I know that lina core is too hard to enter or access by a hacker. Yet we all knows that there is no imposible in the internet but lina team already made it more secured in order to have a difficulties in accessing their system.
Your concern has its basis, but I think that is one aspect that Lina.review team needs to address as well. Ideally blockchain technology can help trace the links of transactions. Unfortunately, it is not enough to prevent hacking. We can only look forward at Lina making its platform secured. I think there is a portion of payment allocated for Bug detection or similar findings in Lina.review. Good luck to us.
Good luck to the hackers. There is a chance that the possible attacks of the hackers will occur in the lina but as long as the lina core is secured and accessible only by few people, hackers can't enter its system otherwise there are inside job. But then, let see on how does lina will protect their clients and firms in possible hack.
Even the secured token and exchange can attack by the hackers. In my opinion, there is no impossible in the internet. Hackers can access lina core though it has the hardest system ever. There will be a time that the hackers will make an access for them to enter. Internet is different from reality. The impossible may become possible by the internet.
