NodeCore Bootstrap File

See: NodeCore_QuickStart, HowTo_run_NodeCore

Overview

Syncing NodeCore from scratch could take a long time. While this is always an option, sometimes people may want a faster way.

There is a bootstrap file, which provides this nodecore.dat file.

The latest bootstrap is available from:

https://testnet.explore.veriblock.org/api/stats/download

This includes checksums for the zip/tar files, as well as the unzipped nodecore.dat file itself:

{
  ...
  "bootstrapfile_zip":  "http://mirror1.veriblock.org/nodecore-bootstrap-270000.zip",
  "bootstrapfile_tar":  "http://mirror1.veriblock.org/nodecore-bootstrap-270000.tar.gz",
  "bootstrapfile_zip_checksum":  "26f217aa7dc91e14e61dbf9ba085b515",
  "bootstrapfile_tar_checksum":  "d7283707364f923161ce1ccbf2aaab88",
  "bootstrapfile_nodecoredat_checksum":  "2bc879b95bc2be3f893f47f61686fa18",
  ...
}

How to use the bootstrap file

1. Download it
2. Unzip it (this provides a "nodecore.dat" file, which will be several GB)
3. Place it in the "nodecore\bin\testnet" folder. If the "testnet" folder does not exist, then create it.

End result will be the file "nodecore\bin\testnet\nodecore.dat"

Checksum

The API also provides the corresponding checksum via md5sum. Run md5sum against the downloaded file (or the unzipped nodecore.dat file), and it should match the checksum in the API.

md5sum nodecore-bootstrap-XXXXX.tar.gz
