v1.4.18 (#193)

* Remove bootstrap peer (#189)

* Change bootstrap servers to DHT-only peers (#187)

* support voucher file-based claims (#183)

* Change bootstrap servers to DHT-only peers

Changing my bootstrap servers to DHT-only peers with somewhat lower
specs. One of the new ones is in the US and the other one is in
Switzerland. Both use reliable providers and have 10Gbps network
interfaces.

* Don't run self-test in DHT-only mode (#186)

* support voucher file-based claims (#183)

* Don't run self-test in DHT-only mode

The node tries to create a self-test when ran with the `-dht-only`
flag, but it doesn't load the KZG ceremony data in DHT-only mode
which leads to a crash.

Don't run self-test when the `-dht-only` flag is set.

I tested by starting a node locally with and without existing
self-test and with the `-dht-only` flag.

+# Release Signatories
+
+Scripts in this folder are tools for release signers to build and sign Quilibrium binaries.
+
+Requirements:
+- bash environment (Ubuntu, macOS, etc.)
+- openssl - digests and signatures
+- git - to checkout this branch
+- Docker - to run a container with golang and compile binaries
+- [Taskfile](https://taskfile.dev/installation/)
+
+Checkout the whole repo from a release branch and then in the `signers` folder you can run `task` commands. Before you
+can run commands you have to copy `.env.example` to `.env` and fill it out. You need a local folder with all the pem
+files, required by signature verification.
+
+Important tasks:
+- `task build` to build the binaries in a dedicated docker image
+- `task verify:build` to verify that you can build the exact same binaries
+- `task verify:digest` to verify the digests
+- `task verify:signatures` to verify all signatures
