I think, I need to send mempool request, get all new transactions and include its in new block. Or am I wrong?

Hi!

Thank you for answer.

I would like to clarify some things.

1. I need to have full blockchain or only full headers for new block generation?

2. Why do I need full blocks for new block generate?

3. How can I get block template and generate new block with libbitcoin?

No code can generate a valid block without maintaining the chain.

Hello!

I develop FPGA mining device and I don’t want use bitdoind. Bitcoind for work download full blockchain(300GB).

I wand write lightweight cliend, without bitcoind, that get information from Bitcoin P2P similar like “getblocktemplate” request and if my device find bloc hash (J) send it to network.

Say me please, how I do this with libbitcoin ?
