===Instructions to run your grin node/wallet locally below===
Download Grin binary: https://github.com/mimblewimble/grin/releases

================================================================================
LINUX
================================================================================
1. Download  grin_full_mainnet_20260315.tar.gz  and  grin_full_mainnet_20260315.sha256
2. Verify    sha256sum -c grin_full_mainnet_20260315.sha256
3. Extract   tar -xzf grin_full_mainnet_20260315.tar.gz
4. Stop your Grin node
5. Remove old chain_data, move extracted folder in its place
6. Set in grin-server.toml:
   archive_mode = true
   chain_type = "Mainnet"
7. Start Grin node

--- Alternative: on-the-fly extraction (no .tar.gz saved locally) -------------
  Use this if disk space is tight or you want to skip the verification step.
  Streams the archive directly into tar — nothing is stored temporarily.
  SHA256 checksum verification is skipped.

  1. Stop your Grin node
  2. Remove old chain_data:  rm -rf /path/to/grin_dir/chain_data
  3. Run from your Grin node directory:
       cd /path/to/grin_dir
       wget -O - https://<this-server-url>/grin_full_mainnet_20260315.tar.gz | tar -xzvf -
  4. Set in grin-server.toml and start Grin node (steps 6 and 7 above)
--------------------------------------------------------------------------------

================================================================================
WINDOWS (PowerShell - tar is built-in)
================================================================================
1. Download all files to a folder
2. Verify    Get-FileHash -Algorithm SHA256 grin_full_mainnet_20260315.tar.gz
             Compare with value in grin_full_mainnet_20260315.sha256
3. Extract   tar -xzf grin_full_mainnet_20260315.tar.gz
4. Stop Grin, replace chain_data folder
5. Edit grin-server.toml (in %USERPROFILE%\.grin\main\):
   archive_mode = true
   chain_type = "Mainnet"
6. Start Grin node

--- Alternative: on-the-fly extraction (no .tar.gz saved locally) -------------
  Use this if disk space is tight or you want to skip the verification step.
  Requires curl.exe and tar — both built into Windows 10 / 11 by default.
  Streams the archive directly into tar — nothing is stored temporarily.
  SHA256 checksum verification is skipped.

  1. Stop your Grin node
  2. Delete the old chain_data folder in Explorer or with:
       Remove-Item -Recurse -Force ":USERPROFILE\.grin\main\chain_data"
  3. Navigate to your Grin node directory in PowerShell, then run:
       cd ":USERPROFILE\.grin\main"
       curl.exe -L "https://<this-server-url>/grin_full_mainnet_20260315.tar.gz" | tar -xzf -
  4. Edit grin-server.toml and start Grin node (steps 5 and 6 above)
--------------------------------------------------------------------------------

================================================================================
GRIM WALLET  (https://gri.mw)
================================================================================
1. Download and verify (see Linux or Windows section above)
2. Stop Grim wallet
3. Replace chain_data in:
   Windows : %USERPROFILE%\.grim\main   Linux   : ~/.grim/main/
   macOS   : ~/Library/Application Support/grim/main/
4. Edit grin-server.toml in that folder:
   archive_mode = true
   chain_type = "Mainnet"
5. Start Grim - first run may take a few minutes to verify the chain

================================================================================
Notes:
  archive_mode = true  -> full node (all history, ~20 GB+)
  archive_mode = false -> pruned node (recent data, ~6 GB+)
  chain_type = "Mainnet" uses port 3414
  chain_type = "Testnet" uses port 13414
  chain_data location set by db_root in grin-server.toml
