v0.9.0 (2020-11-13)

Full Changelog

The main features of this release are:

  • a reputation tracking system which starts to link node reputation to quality of service
  • a new component, the nym-network-monitor, which tracks whether nodes are working properly and providing good service
  • automatic node registration and de-registration at node startup
  • working Cosmos validators with a nym token
  • starting to decentralize the old directory server into the validators
  • a new block explorer at https://testnet-explorer.nymtech.net which looks the same as the old dashboard but is the basis of something much more advanced. It can be run by anyone.

v0.6.0 (2020-04-07)

Full Changelog

This release fixes bugs in v0.5.0. All testnet node operators are advised to upgrade from v0.5.0.

  • fixed premature EOFs on socket connections by using the new multi-TCP client
  • fixed a bug causing client and mixnode connection hangs for misconfigured nodes
  • by default 'Debug' section of saved configs is now empty and default values are used unless explicitly overridden
  • introduced packet chunking allowing clients to send messages of arbitrary length. Note that packet retransmission is not implemented yet, so for longer messages, you might not get anything
  • mixnodes now periodically log stats regarding number of packets mixed
  • fixed possible client hang ups when sending high rates of traffic
  • preventing mixes from starting with same announce-host as an existing node
  • fixed overflow multiplication if connection backoff was set to a high value

Closed issues:

  • Periodic activity summary #172
  • Move contents of 'common/addressing' into 'common/nymsphinx' #161
  • Make builds simpler for node operators #114
  • Chunking in nym-client (receive) #83
  • Chunking in nym-client (send) #82

v0.5.0 (2020-03-23)

Full Changelog

  1. Introduced proper configuration options for mixnodes, clients and providers. Everything is initialised with the init command that creates a saved config.toml file. To run the binary you now use nym-<binary-name> run, for example nym-mixnode run. Each flag can be overwritten at any stage with the following priority: run flags, data in config.toml and finally init flags.
  2. Made mixnet TCP connections persistent. When sending a Sphinx packet, it should no longer go through the lengthy process of establishing a TCP connection only to immediately tear it down after sending a single packet. This significantly boosts throughput.
  3. A lot of work on code clean up and refactoring including some performance fixes.
  4. Client now determines its default nym-sfw-provider at startup and should always try to connect to the same one. Note: we still can't reliably run more than a single provider on the network.
  5. Logging messages now have timestamps and when running at more aggressive log mode (like debug or even trace) we should no longer be overwhelmed with messages from external crates.
  6. Initial compatibility with Windows. Please let us know if you have problems.
  7. More work on validator, including initial Tendermint integration in Rust, and the start of the mixmining system.

Closed issues:

  • Introduce timestamps to log messages #124

Full Changelog

Nym 0.4.0 Platform

In this release, we're taking a lot more care with version numbers, so that we can ensure upgrade compatibility for mixnodes, providers, clients, and validators more easily.

This release also integrates a health-checker and network topology refresh into the Nym client, so that the client can intelligently choose paths which route around any non-functional or incompatible nodes.
