Building a stronger Bitcoin developer community

In Summer 2016, I’d been interested in Bitcoin for a little over a year. I’d been slowly becoming more and more enchanted by this strange and wonderful technology, and I’d finally made the step of quitting my job of eight years with the intention of finding a way to make…

What’s new in Bitcoin Core v0.15 — part 3

Yesterday, I wrote about how fee estimation is better in v0.15, but what happens if you send a transaction without enough fee to be included in a block? Somehow you need to encourage miners to include your transaction, or it’ll be stuck in limbo forever (or at least until it…
