21/09/2017  · AFAIK generate and getblocktemplate use the same code to produce the block template which generate uses to then actually make the block. Unless you mean it would allow you to workaround your issue (by repeatedly calling getblocktemplate and just checking for it there); in which case this is just a workaround, not a fix of the actual problem (transactions just sent not getting into blocks).

One possible reason may that with Bitcoin Core 0.13.1, it was mandatory to use SegWit-compatible mining software. When SegWit transactions are included in a block, a coinbase commitment to the witnesses is required by consensus rules. As the eventual selection of transaction in the block is done by the mining software, old mining software cannot be used to construct a SegWit block. On testnet.

23/08/2016  · Testnet use is supported, and after BIP 141 is updated with proposed parameters, a future release of Bitcoin Core is expected that implements those parameters for mainnet. Furthermore, because segwit activation is not yet specified for mainnet, version 0.13.0 will behave similarly as other pre-segwit releases even after a future activation of BIP 141 on the network.

From 0.13.1 onwards OS X 10.7 is no longer supported. 0.13.0 was intended to work on 10.7+, but severe issues with the libc++ version on 10.7.x keep it from running reliably. 0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly. Notable changes Segregated witness soft fork. Segregated witness (segwit) is a soft fork that, if activated, will.
