confirming transactions on regtest

[yayitswei]

Could you point me to an example that mines on regtest and confirms transactions? This is a great start but I'm using miner.createJob and job.mineAsync() and finally chain.add(block) as suggested and it's not adding any transactions I've sent previously into the new block. When I look up the transaction it has 0 confirmations.

Thanks for your help!

I'll include a better example with a variety consecutive blocks / wallet confirms. But running this should add a block / tx to the chain.

Thanks @Rojii! That code is very helpful and I can see the transactions in my newly mined blocks now. But like you said, the wallet transactions aren't hooked up yet, so I'm looking forward to your second example.

try this one out ,

I'm going to close this for now @yayitswei. We'll hopefully try and get a guide and script up as well in the near future up on bcoin.io.

I forgot to reply, but your new code was helpful too- thanks!

[jonajosejg]

No Problem, I'll include a new guide in the next week with a much more functions.

@Rojii I tried you code, it doesnt seem to solve the problem tho. I looks like the transaction is added to the chain but I dont get any confirmation.

[info] (chain) Block 3a416a3b1a5a4321ca3c3f7665e7763bc7b86955441433996fe85e5aa9dc8248 (1) added to chain (size=196 txs=1 time=13.296796).

I tried to create blocks manually with the client but that doesnt work either.

Any idea what im doing wrong?

If you want me to add manual code for adding blocks by height / entry (increment by 1 in height or w.e) let me know. But the code above will add all of the transactions correctly
