|
||
accomplish is connecting to a service like Bitcoin Core,
|
||
and use that for tasks like generating addresses,
|
||
verifying payments and
|
||
monitoring the blockchain. This typically happens through
|
||
tools like <code>bitcoin-cli</code>, or the Bitcoin Core HTTP RPC
|
||
server interface. One big drawback to this, is that you
|
||
lose all type-safety in your application. Even if you
|
||
have a custom type that represents a Bitcoin transaction,
|
||
how do you get that to play nicely with the result that
|
||
Bitcoin Core gives you after signing a transaction? A
|
||
random hexadecimal string in a HTTP response could be
|
||
anything from a public key, a transaction or a block
|
||
header.</p>
|
||
<p>We've done all the mundane work of wiring requests and
|
||
responses from Bitcoin Core to the powerful and safe types
|
||
found in Bitcoin-S. We've also written a bunch of tests,
|
||
that verify that all of this actually works.
|
||
You'll know for sure that you're sending
|
||
a valid public key to <code>importmulti</code>, and you when doing
|
||
RPC calls like <code>getblockheader</code> we'll even parse the
|
||
hexadecimal string into a complete header that you can
|
||
interact with without goofing around with bits and bytes.</p>
|
||
<p>We currently have RPC clients for Bitcoin Core, Eclair, Lnd.</p>
