When i read about merkle trees.. I saw we shall build a system wherein we could club all the transactions that happend in like 10 minutes to stay in a block. I mean.. whatever is known.. the known transactions are made to a block. But my question is if I need to group my logs per component.. like.. every one hour I get a new log file on a product.. and I want that all to stay together in the same block as and when it happens.. is it possible?
Concisely.. is it possible to dynamically add transactions in a merkle tree? Is that a bad implementation? Does computational power increases in this cos everytime one transaction is added.. we need to rehash the entire blockchain,?
