[dependabot]

Bumps github.com/btcsuite/btcd from 0.20.1-beta to 0.21.0-beta.

Release notes

Sourced from github.com/btcsuite/btcd's releases.

btcd v0.21.0-beta

This release of btcd is primarily to act as a catchup for the various changes that have accumulated and to help move back to a more regular schedule.

Verifying the Release

In order to verify the release, you'll need to have gpg or gpg2 installed on your system. Once you've obtained a copy (and hopefully verified that as well), you'll first need to import the keys that have signed this release if you haven't done so already:

Once you have the required PGP keys, you can verify the release (assuming manifest-v0.21.0-beta.txt and manifest-v0.21.0-beta.txt.sig are in the current directory) with:

gpg --verify manifest-v0.21.0-beta.txt.sig

You should see the following if the verification was successful:

gpg: assuming signed data in 'manifest-v0.21.0-beta.txt'
gpg: Signature made Fri 28 Aug 2020 12:40:24 PM EDT
gpg:                using DSA key 0DB39EAF526568682088EEDFB15210D35378BD54
gpg: Good signature from "John C. Vernaleo <john@netpurgatory.com>" [ultimate]

That will verify the signature of the manifest file, which ensures integrity and authenticity of the archive you've downloaded locally containing the binaries. Next, depending on your operating system, you should then re-compute the sha256 hash of the archive with shasum -a 256 <filename>, compare it with the corresponding one in the manifest file, and ensure they match exactly.

Verifying the Release Binaries

As of this release, our release binaries are fully reproducible thanks to go1.13! Third parties are now able to verify that the release binaries were produced properly without having to trust the release manager(s). See our reproducible builds guide for how this can be achieved. The release binaries are compiled with go1.14, which is required by verifiers to arrive at the same ones.

Finally, you can also verify the tag itself with the following command:

git verify-tag v0.21.0-beta

You should see something along the lines of this in the case of a valid tag:

gpg: Signature made Fri 28 Aug 2020 09:58:10 AM EDT
gpg:                using DSA key 0DB39EAF526568682088EEDFB15210D35378BD54
gpg: Good signature from "John C. Vernaleo <john@netpurgatory.com>" [ultimate]

Building the Contained Release

Users are able to rebuild the target release themselves without having to fetch any of the dependencies. In order to do so, assuming that vendor.tar.gz and btcd-source-v0.21.0-beta.tar.gz are in the current directory, follow these steps:

tar -xvzf vendor.tar.gz
tar -xvzf btcd-source-v0.21.0.tar.gz
GO111MODULE=on go install -v -mod=vendor
GO111MODULE=on go install -v -mod=vendor ./cmd/btcctl
