Zcash Testnet DoS Attack

UPDATE- Please note that the problems on the Testnet turned out to be a bug, not a DoS attack as originally assumed: https://minezcash.com/zcash-network-bug/ I am very disappointed to report that the Zcash Testnet server has already been the subject of a DoS (Denial of Service) attack.

New Zcash Alpha: 2MB Blocks

Last night the Zcash team released an update to the Test Network. As I mentioned in this post Instead of a complete reset of the network which normally wipes all test coins the Zcash developers have natively implemented a Hard Fork increasing the block size to 2MB. This new release (z6) also implements a much needed Equihash optimization that randomizes the nonce values to...
