@be4i That's strange. I've just tested it against my zcash-testnet node and was able to mine tons of blocks without any rejections.

[be4i]

@oliverw so must me something in my node configuration ?

[zywoo]

@be4i @oliverw I’ve tested against my zcash-testnet node and had mined lotst of blocks,but cathed the same exception of "tx-overwinter-active" yesterday. " "

I believe that's the Overwinter upgrade that's coming this summer (Block 207,500 on testnet) not being implemented in MiningCore yet

@bitspill Thanks for the links. I've spotted references to "overwinter" in the zcash codebase but missed the pages you've linked.

@be4i @zywoo @bitspill Confirmed to be currently a testnet-exclusive problem that needs to be fixed before it turns into a production problem on mainnet. Hoping to fix tommorow.
