computer and network connection, it will likely take a few hours at least, but
some people report full nodes syncing in less than 1.5 hours.
# Fastest way to sync (bootstrap)
The quickest way to get a fully-synced node is the signed bootstrap snapshot, which
installs a pre-built blockchain so you skip re-validating the whole chain from genesis:
```sh
# Stop dragonxd first if it is running, then:
./util/bootstrap-dragonx.sh
```
The script preserves your `wallet.dat` and `DRAGONX.conf`, verifies the download's
checksums and (once a release key is published) its cryptographic signature, then starts
you near the chain tip. If you prefer to sync from the network instead, a larger
`-dbcache` (e.g. `-dbcache=2048`) noticeably speeds up the initial block download.

## AI/LLM Usage Policy
> [!IMPORTANT]
> This project does **NOT** accept pull requests that are fully or predominantly AI-generated. AI tools may be utilized solely in an assistive capacity. The human submitting new code to the project must actually understand the code changes they are submitting.
Code that is initially generated by AI and subsequently edited will still be considered AI-generated. AI assistance is permissible only when the majority of the code is authored by a human contributor, with AI employed exclusively for corrections or to expand on verbose modifications that the contributor has already conceptualized (e.g., generating repeated lines with minor variations).
If AI is used to generate any portion of the code, contributors must adhere to the following requirements:
1. Explicitly disclose the manner in which AI was employed, including the exact model and quantization used and if it was done via local AI, such as with llama.cpp or a SaaS provider.
2. Perform a comprehensive manual review prior to submitting the pull request.
3. Be prepared to explain every line of code they submitted when asked about it by a maintainer.
4. It is strictly prohibited to use AI to write your posts for you (bug reports, feature requests, pull request descriptions, Github discussions, responding to humans, ...).
## Types of contributions we're looking for
There are many ways you can directly contribute to Hush:
@@ -31,7 +46,6 @@ Interested in making a contribution? Read on!
Before we get started, here are a few things we expect from you (and that you should expect from others):
* Be kind and thoughtful in your conversations around this project. We all come from different backgrounds and projects, which means we likely have different perspectives on "how free software and open source is done." Try to listen to others rather than convince them that your way is correct.
* Open Source Guides are released with a [Contributor Code of Conduct](./code_of_conduct.md). By participating in this project, you agree to abide by its terms.
* If you open a pull request, please ensure that your contribution does not increase test failures. If there are additional test failures, you will need to address them before we can merge your contribution.
* When adding content, please consider if it is widely valuable. Please don't add references or links to things you or your employer have created as others will do so if they appreciate it.

# Signing the DragonX bootstrap archive
`util/bootstrap-dragonx.sh` verifies a detached signature of `DRAGONX.zip` against a
public key **embedded in the script** (`BOOTSTRAP_PUBKEY`). Because the key ships in the
repo/binary and is not downloaded from the bootstrap server, a compromised bootstrap host
cannot forge a valid signature — unlike the `.md5`/`.sha256` files, which are served from
the same host and only detect corruption.
Until a real key is embedded, `BOOTSTRAP_PUBKEY` is the placeholder and the script skips
signature enforcement (with a warning), so existing users are unaffected. Once a real key
is pasted in, an unsigned or invalid bootstrap is **refused**.
## One-time: create the signing keypair (offline)
Keep the private key OFFLINE (air-gapped if possible). Ed25519 or RSA-4096 both work with
the `openssl dgst -sha256 -verify` check the script uses; RSA-4096 maximizes compatibility:
```sh
# Private key — keep secret, never publish
openssl genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:4096 -out dragonx-bootstrap.key
# Public key — paste into bootstrap-dragonx.sh
openssl pkey -in dragonx-bootstrap.key -pubout -out dragonx-bootstrap.pub
cat dragonx-bootstrap.pub
```
Paste the full PEM (including the `-----BEGIN/END PUBLIC KEY-----` lines) into
`BOOTSTRAP_PUBKEY` in `util/bootstrap-dragonx.sh`, e.g.:
```sh
BOOTSTRAP_PUBKEY="$(cat <<'PEM'
-----BEGIN PUBLIC KEY-----
... base64 ...
-----END PUBLIC KEY-----
PEM
)"
```
## Each release: sign the archive and publish the signature
```sh
openssl dgst -sha256 -sign dragonx-bootstrap.key -out DRAGONX.zip.sig DRAGONX.zip
```
Upload `DRAGONX.zip.sig` next to `DRAGONX.zip` (and its `.md5`/`.sha256`) on every
bootstrap host (`bootstrap.dragonx.is`, `bootstrap2.dragonx.is`). Verify locally first:
```sh
openssl dgst -sha256 -verify dragonx-bootstrap.pub -signature DRAGONX.zip.sig DRAGONX.zip
# -> "Verified OK"
```
## Rotating the key
Embed the new public key in the script, sign future archives with the new private key, and
release a new client version. Old clients keep trusting the old key; coordinate the cutover
with a release so users upgrade before the old key is retired.

2. Fetches the current tip block in raw hex

4. Tampers with nBits to set difficulty=1 (0x200f0f0f)
