I discovered that also blocks from other apps, peerchat in my case, are stored in the database.
Not aware that this might happen I tried to unpack the transaction, which results in a crash.
What I had to do is to check block.type before unpacking.
What I can also do is to change the serviceId for the TrustChainCommunity, but as we are also open source, this serviceId is also addressable by other apps. What I fear is that someone can use DOS attacks to make the db explode (no disk space left).
Am I missing something?
I would rather add an encrypted API key in the blocks, so that the app can check if this block comes from the same app and only store those blocks.

Thx for quick reply.
I initialize the trustchain as follows, in this case I can only validate our own specific blocks.
trustchain.registerTransactionValidator(Backend.BLOCK_TYPE, object : TransactionValidator {
Do I have to subclass the TrustChainCommunity, rewrite the class itself or are there better posibilities?
Sry, for asking noob questions, but I started with Kotlin 2 weeks ago. I am more the C/C++/C# guy ;-)
