Package btcutil provides bitcoin-specific convenience functions and types.
|

The test coverage is currently ~76%, however it will improved to 100% in the
|
||||||
|
near future. See `test_coverage.txt` for the gocov coverage report.
|
||||||
|
Alternatively, if you are running a POSIX OS, you can run the `cov_report.sh`
|
||||||
|
script for a real-time report. Package btcutil is licensed under the liberal
|
||||||
|
ISC license.
|
||||||
|
|
||||||
|
This package was developed for btcd, an alternative full-node implementation of
|
||||||
|
bitcoin which is under active development by Conformal. Although it was
|
||||||
|
primarily written for btcd, this package has intentionally been designed so it
|
||||||
|
can be used as a standalone package for any projects needing the functionality
|
||||||
|
provided.
|
||||||
|
|
||||||
|
## Documentation
|
||||||
|
|
||||||
|
Full `go doc` style documentation for the project can be viewed online without
|
||||||
|
installing this package by using the GoDoc site here:
|
||||||
|
http://godoc.org/github.com/conformal/btcutil
|
||||||
|
|
||||||
|
You can also view the documentation locally once the package is installed with
|
||||||
|
the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
|
||||||
|
http://localhost:6060/pkg/github.com/conformal/btcutil
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ go get github.com/conformal/btcutil
|
||||||
|
```
|
||||||
|
|
||||||
|
## GPG Verification Key
|
||||||
|
|
||||||
|
All official release tags are signed by Conformal so users can ensure the code
|
||||||
|
has not been tampered with and is coming from Conformal. To verify the
|
||||||
|
signature perform the following:
|
||||||
|
|
||||||
|
- Download the public key from the Conformal website at
|
||||||
|
https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
|
||||||
|
|
||||||
|
- Import the public key into your GPG keyring:
|
||||||
|
```bash
|
||||||
|
gpg --import GIT-GPG-KEY-conformal.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
- Verify the release tag with the following command where `TAG_NAME` is a
|
||||||
|
placeholder for the specific tag:
|
||||||
|
```bash
|
||||||
|
git tag -v TAG_NAME
|
||||||
|
```

Block Overview
|
||||||
|
|
||||||
|
A Block defines a bitcoin block that provides easier and more efficient
|
||||||
|
manipulation of raw wire protocol blocks. It also memoizes hashes for the
|
||||||
|
block and its transactions on their first access so subsequent accesses don't
|
||||||
|
have to repeat the relatively expensive hashing operations.
