Is something wrong with the keycoin blockchain and/or client?
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.
Can someone answer this post? Why there are almost no normal transactions in the blockchain? Only Bagpipe has given reasonable explanation (that enormous amounts of coins are owned by very small number of people who obviously have no need to do transactions). But his answer doesn't explain why number of transactions was much higher before (the people in this small group probably owned enormous amounts of coins from the beginning).
I've already answered your question. If there are no other transactions then nobody is moving coins around. It doesn't mean anything is broken, blocks will continue to be generated regardless of whether people are moving coins or not.
