- Znet has been operational for several weeks on a closed beta basis, but is now open to the public
- The testnet will offer the baseline for running an IOTA network without a co-coordinator
- Ledger validation is not included in the testnet to make the first iteration with CLIRI simpler
On March 6, IOTA foundation provided new details of Znet, a testnet without a coordinator. The IOTA foundation invites the crypto community to take part in discussion of the testnet.
Znet has now been up for several weeks, but now it is being made available for public participation. The crypto community is welcomed to join in on the discussion on Discord. People will be able to check out its live visualization, contribute ideas, run CLIRI nodes and also join the network.
Eliminating the coordinator
CLIRI stands for coo-less IRI, and that’s what makes it so unique. It is a fork of IRI without any Coo-related components. This will provide a backbone for running an IOTA network that has no coordinator. This is all devised to create an understanding of the possible challenges that a Coo-less mainnet will encounter.
A ‘milestone’ is a transaction that has an IOTA foundation signature. All transactions referenced by a milestone are automatically confirmed. This is the coordinator’s way of combating double spends, but the centralized nature of the coordinator is also the reason it is necessary that it be eliminated however it is not that easy. Milestones are used in various points such as:
- Selecting a starting point
- Calculation of ledger state
- Synchronizing nodes
So that the first iteration with CLIRI is simple, ledger validation has been removed. That means all transactions will be deemed valid as long as they meet the PoW standards. This will run on ZNet, the new testnet. The aim is to ensure this code is stable before complex validation logic is implemented.
This official launch is also aimed at gathering more analytical data on ZNet’s performance. This is ensured by the introduction of a new API that computes transactions confirmation confidence; hence confidence levels can be tracked and a timeline established on how long a transaction takes to reach high confidence and what fraction of the transactions reach those levels.
