DREP Chain

ISC License

What is drep?

drep is a full node implementation of Drep written in Go (golang).

It acts as a fully-validating chain daemon for the Drep cryptocurrency. drep maintains the entire past transactional ledger of Drep and allows relaying of transactions to other Drep nodes around the world.

This software is currently under active development. It is extremely stable and has been in production use since February 2018.

What is a full node?

The term 'full node' is short for 'fully-validating node' and refers to software that fully validates all transactions and blocks, as opposed to trusting a 3rd party. In addition to validating transactions and blocks, nearly all full nodes also participate in relaying transactions and blocks to other full nodes around the world, thus forming the peer-to-peer network that is the backbone of the Drep cryptocurrency.

The full node distinction is important, since full nodes are not the only type of software participating in the Drep peer network. For instance, there are 'lightweight nodes' which rely on full nodes to serve the transactions, blocks, and cryptographic proofs they require to function, as well as relay their transactions to the rest of the global network.

Why run drep?

As described in the previous section, the Drep cryptocurrency relies on having a peer-to-peer network of nodes that fully validate all transactions and blocks and then relay them to other full nodes.

Running a full node with drep contributes to the overall security of the network, increases the available paths for transactions and blocks to relay.

In terms of individual benefits, since drep fully validates every block and transaction, it provides the highest security and privacy possible when used in conjunction with a wallet that also supports directly connecting to it in full validation mode, such as wallet.

Minimum Recommended Specifications (drep only)

  • 100 GB disk space (as of September 2018, increases over time)
  • 1.5GB memory (RAM)
  • ~150MB/day download, ~1.5GB/day upload
    • Plus one-time initial download of the entire block chain
  • Windows 7/8.x/10 (server preferred), macOS, Linux
  • High uptime

Getting Started

So, you've decided to help the network by running a full node. Great! Running drep is simple. All you need to do is install drep on a machine that is connected to the internet and meets the minimum recommended specifications, and launch it.

Also, make sure your firewall is configured to allow inbound connections to port 55555.
