This marks the fourth minor release of poold in the 0.5.x series! This release includes bug fixes, some developer improvements and enables the new script-enforced lease channel type for lnd v0.14.x-alpha or later.

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:

curl https://keybase.io/guggero/pgp_keys.asc | gpg --import

Once you have the required PGP keys, you can verify the release (assuming manifest-v0.5.4-alpha.txt and manifest-v0.5.4-alpha.sig are in the current directory) with:

gpg --verify manifest-v0.5.4-alpha.sig manifest-v0.5.4-alpha.txt

You should see the following if the verification was successful:

gpg: Signature made Mi 29 Jul 2020 14:59:19 CEST
gpg:                using RSA key 6E01EEC9656903B0542B8F1003DB6322267C373B
gpg: Good signature from "Oliver Gugger <gugger@gmail.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

Our release binaries are fully reproducible. Third parties are 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 go1.17.3, which is required by verifiers to arrive at the same ones.

The make release command can be used to ensure one rebuilds with all the same flags used for the release. If one wishes to build for only a single platform, then make release sys=<OS-ARCH> tag=<tag> can be used.

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

The signature on the tag itself can be verified with:

git verify-tag v0.5.4-alpha

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 poold-source-v0.5.4-alpha.tar.gz are in the current directory, follow these steps:

tar -xvzf vendor.tar.gz
tar -xvzf lnd-source-v0.5.4-alpha.tar.gz
GO111MODULE=on go install -v -mod=vendor ./cmd/poold
GO111MODULE=on go install -v -mod=vendor ./cmd/pool

The -mod=vendor flag tells the go build command that it doesn't need to fetch the dependencies, and instead, they're all enclosed in the local vendor directory.

Additionally, it's now possible to use the enclosed release.sh script to bundle a release for a specific system like so:

make release sys="linux-arm64 darwin-amd64"
