This is a quick update to inform people on how to switch over Steem-in-a-box (SIAB) to the [Hive fork](https://hive.io).

# [Announcement of Hive network - SteemPeak Post](https://steempeak.com/communityfork/@hiveio/announcing-the-launch-of-hive-blockchain)

As the hard fork is due in approx. 9 hours from now, this post may contain a few small mistakes, and limited information. DM me on Discord or other platforms if you spot any issues :)

Hive is a hard fork of Steem without the Steemit Inc. ninja-mined stake (SINMS).

Today (Friday 20 Mar), Steem will split into two networks: Steem, and Hive.

Witnesses who are showing as `0.23.0` are running the Hive code, and are ready for the chain split: https://www.eztk.net/witnesses.php?id=someguy123

The HF lock-in time is: `20-Mar-2020 @ 14:00 UTC`  (see here for current time: https://time.is/UTC )


# Updating to Hive - 0.23.0

### Updating Steem-in-a-box core files

Updating Steem-in-a-box's **core files** (i.e. the SIAB application itself) is very simple as always:

```sh
cd ~/steem-docker       # Enter the folder containing SIAB
git checkout master     # Ensure you're on the right branch
git pull                # Download and install (merge) any code updates
```

# Updating Steem-in-a-box (SIAB) to Hive 0.23.0

If you are running Steem 0.22.0 or 0.22.1 - you can upgrade directly to Hive 0.23.0 without needing a replay.

If you upgrade after the hard fork time (20-Mar-2020 @ 14:00 UTC), you may have to replay.

### Upgrading non-MIRA 

(i.e. installations using /dev/shm/shared_memory.bin)

```sh
cd ~/steem-docker
# Ensure you're on the 'master' branch
git checkout master
# Update SIAB's "core files" such as run.sh
git pull
# Install the latest image and restart
./run.sh install someguy123/hive:latest
./run.sh restart
```

### Upgrading MIRA

(i.e. installations using RocksDB, such as @privex's [Node-in-a-box servers](https://www.privex.io/articles/steem-node-in-a-box))

```sh
cd ~/steem-docker
# Ensure you're on the 'master' branch
git checkout master
# Update SIAB's "core files" such as run.sh
git pull
# Install the latest Hive MIRA-enabled image and restart
./run.sh install someguy123/hive:latest-mira
./run.sh restart
```

### Building from source

If you don't want to use my binary images, you can build the image manually.

First make sure your Steem-in-a-box core files are up to date, as the new `STEEM_SOURCE` feature is a recent addition in the v2.1.0 release (released 12:13 AM UTC on Mon 24 Feb)

```sh
cd ~/steem-docker
# Ensure you're on the 'master' branch
git checkout master
# Update SIAB's "core files" such as run.sh
git pull

```

Next, you'll want to set the environment variable `STEEM_SOURCE` to the Hive repository `https://github.com/openhive-network/hive.git`

```sh
# Use Hive's Git repository instead of steemit/steem
export STEEM_SOURCE="https://github.com/openhive-network/hive.git"
```

**WARNING:** By default, ENABLE_MIRA is set to ON in the Dockerfile. Despite this, I strongly recommend explicitly specifying it each time, in-case the default is ever changed.

**Building 0.23.0 with MIRA disabled (use shared_memory.bin)**

The below command will build the branch 0.23.0 from Hive's repo, automatically tag it as `steem` (the default image used by `run.sh`), and passes ENABLE_MIRA=OFF to disable MIRA and use shared_memory.bin instead.

```sh
./run.sh build 0.23.0 tag steem 'ENABLE_MIRA=OFF'
```
**Building 0.23.0 with MIRA enabled (use RocksDB)**

The below command will build the branch 0.23.0 from Hive's repo, automatically tag it as `steem` (the default image used by `run.sh`), and passes ENABLE_MIRA=ON to ensure MIRA is enabled (uses RocksDB instead of shared_memory.bin).

```sh
./run.sh build 0.23.0 tag steem 'ENABLE_MIRA=ON'
```



# Installing a new Steem node using Steem-in-a-box

If you'd like to save some time, consider using one of @privex's [Node-in-a-box servers](https://www.privex.io/articles/steem-node-in-a-box). They start from just $40 USD per month, and come pre-installed and pre-replayed with Hive v0.23.0 - so your node will be synced and ready to use within minutes :)

**NOTE:** Pre-ready Hive servers (VPS-HIVE-FIN) are currently restricted to people who have reserved orders in advance, as announced on [the Privex Discord](https://discord.gg/5XrMuSv). We'll be opening the package to the public within a few hours, giving time for customers who've reserved VPS's to finish their orders.

If you'd rather install Steem-in-a-box on a fresh server, please check my HF20 guide at https://steemit.com/witness-category/@someguy123/the-easy-way-to-install-or-upgrade-to-hardfork-20-steem-in-a-box - it's still accurate for HF23
