0.9.9 Guide to the Galaxy

Version 1.0 of Nethermind is just around the corner and with 0.9.9 comes one of the most critical features - fast sync.

Nethermind fast sync allows you to sync Ethereum mainnet in around 5 hours on standard VMs (for example $40 a month Digital Ocean or UpCloud VMs). It can go below 4 hours on stronger specs :)

In our own tests (and of some of our friends) running Geth and Nethermind side by side on exactly same configurations shows Nethermind to be 3x faster and require 4x less disk space to store Ethereum mainnet state than Geth.

(bear in mind that we do not download tx receipts and that we are waiting for more performance tests coming from you)

Goerli testnet support is equally great with ~3 minutes fast sync and under 200MB of data stored at the current chain height.

You can download version 0.9.9 from https://github.com/NethermindEth/nethermind/releases/tag/0.9.9

Nethermind is already stable, supporting JSON RPC calls with both Geth and Parity style EVM tracing. It can also run POA based private networks with your chainspec files.

We are in the process of updating the documentation so you can expect this link:
https://nethermind.readthedocs.io/en/latest/
to bring you more and more info about the release soon.

Note: Nethermind Launcher is a self-contained app - you do not need to install .NET separately to run it.

Fairy Ferryman

New in this release:

• multiple updates to the performance of network operations
• massively decreased allocations during network nodes discovery and handshakes

Supported networks:

• mainnet
• ropsten (--config ropsten)
