Main Cluster

The KMDLabs main cluster is where the bulk of testing occurs.

The KMDLabs blockchain is the center of a fungible grouping of independent blockchains with the -ac_cc=101 parameter set. This allows for any one of the chains to interact with the other chains via cross chain smart contracts. This is made possible through Komodo’s MoMoM technology.

The independent chains making up the KMDLabs cluster have different parameters permitting testing across blockchains with differing functionalities. New chains can be added to the cluster at any time, giving great flexibility in testing options. The only current requirement is that all chains have no block reward, and use -ac_algo=verushash11 and -ac_staked=20 and -ac_notarypay. This means at this time, main cluster chains cannot use -ac_pubkey or -ac_script. Its possible we can change this in the future. We have options, because the coins can be sent back to the main chain, and the 0BR chains can be replaced at any time.

Tier 2 Notary Node Network

A unique and key feature of KMDLabs is that it has its own notary node network.  This network is second tier to the main KMD notary nodes. In addition to ensuring dPoW for assetchains as KMD notaries do, the KMDLabs’ notaries also perform the function of MoMoM notarization. The notarization process for MoMoM, particularly between low hash rate chains, is a necessity for cross-chain imports and for making certain that export transactions can’t be reversed by a chain reorganization. This MoMoM notarization prevents the creation of coins “out of thin air”.

Example Cluster Configuration

The CFEK test cluster gives an idea of a very basic cluster configuration.

This four chain cluster was used to test cross-chain migrations, assetchain params, PoW/PoS, NN network functionality and a multitude of changes to the underlying STAKED software, among other things.

As you can see the testing possibilities are enormous with even such a basic cluster configuration.

Free to use

Testing on the KMDLabs cluster is free. There is also the possibility of earning bounties, mining and staking and earning through running a KMDLabs Notary Node.

Adding chain(s)

The value of one coin in the cluster is equal to that of any other (1 KMDLabs(LABS)), regardless of what chain it exists on. Therefore a coin mined or staked on XCHAIN is evenly exchangeable for 1 KMDLabs(LABS) and vice versa.

The total coin supply is balanced across the cluster. Adding a new chain to the cluster requires the provable burning of an amount of KMDLabs(LABS) equal to the amount of coins added. Chains other than KMDLabs(LABS) will have a 0 block reward for the time being (ac_end=1). There is a consensus rule in the LABS komodod that means any chain launched in the main cluster cannot have any block reward past block 1, no matter what params are used. Please see the Technical page or contact us on Discord to find the correct method to do this.
