Blockchain explorer shows that almost all of the last several hundreds of blocks contain only one transaction (+coinbase).
This transaction has the same input and output addresses (somebody is sending coins back to himself, could this be related to PoS?). There are almost no normal transactions.
That's how Proof of Stake works, it returns your original coin + interest split into 2 new transactions at each cycle. 1 transaction becomes 2, becomes 4, becomes 8. etc. etc. etc.
This is what keeps transactions moving in a Proof Of Stake coin.
Thanks, I was suspecting something like this. However, to me it would make more sense to use coinbase transaction for this purpose because this transaction actually "generates" new coins (sum of outputs is larger than its input). After the PoW phase the coinbase transactions are empty and probably just unnecessarily pollute the blockchain.
