nuklaivm takes inspiration from morpheusvm implements the functionality of this VM. In addition, nuklaivm also adds additional functionality such as token functionalities(fungible, non-fungible and fraction) and staking native token NAI, has an
emission balancer that keeps track of total supply of NAI, max supply of NAI, staking rewards per block and the emission
address to direct 50% of all fees to.
nuklaivm is considered ALPHA software and is not safe to use in
production. The framework is under active development and may change
significantly over the coming months as its modules are optimized and
audited.

NAIand any other token created by users - ☑ Create a token(fungible, non-fungible, dataset)
- ☑ Mint a token(fungible, non-fungible)
- ☑ Burn a token(fungible, non-fungible)

- ☑ Claim accumulated subscription payment from the Nuklai marketplace
- ☑ Tracks total supply of NAI, max supply of NAI, staking rewards per block and the emission address to direct 50% of all fees to
- ☑ Register validator for staking
- ☑ Unregister validator from staking
- ☑ Delegate
NAIto a validator - ☑ Undelegate
NAIfrom a validator - ☑ Claim the staking/delegation rewards
- ☑ Track the staking information for each users and validators
- ☑ Distribute 50% fees to emission balancer address and 50% to all the staked validators per block
- ☑ Distribute NAI as staking rewards to the validators that have a minimum stake of at least 100 NAI per block
The basis of the nuklaivm is the ability to create, mint, and transfer user-generated
tokens with ease. When creating an asset, the owner is given "admin control" of
the asset functions and can later mint more of an asset, update its metadata
(during a reveal for example), or transfer/revoke ownership (if rotating their
key or turning over to their community).
Assets are a native feature of the nuklaivm and the storage engine is
optimized specifically to support their efficient usage (each balance entry
requires only 72 bytes of state = assetID|publicKey=>balance(uint64)). This
storage format makes it possible to parallelize the execution of any transfers
that don't touch the same accounts. This parallelism will take effect as soon
as it is re-added upstream by the hypersdk (no action required in the
nuklaivm).
On nuklaivm, the emission balancer handles the staking mechanism whereby it tracks the
total supply of NAI, max supply of NAI, staking rewards per block and the emission address to direct 50% of all fees to.
Furthermore, it also rewards all the validators that have a minimum stake and all the users who have a minimum delegated stake to a validator of their choice.

This also allocates all funds on the network to created address: 00c4cb545f748a28770042f893784ce85b107389004d6a0e0d6d7518eeae1292d9. The private
key for this address is 323b1d8f4eed5f0da9da93071b034f2dce9d2d22692c172f3cb252a64ddfafd01b057de320297c29ad0c1f589ea216869cf1938d88c9fbd70d6748323dbf2fa7.
For convenience, this key has is also stored at demo.pk._
Alternatively, you can also run the network via docker:
./scripts/run_docker.sh startAnd you can check out the logs at:
./scripts/run_docker.sh logsTo stop the network, run:
./scripts/stop.shAlternatively, with docker:
./scripts/run_docker.sh stopOn default settings, the address 00c4cb545f748a28770042f893784ce85b107389004d6a0e0d6d7518eeae1292d9 will get the entirety of 853 million NAI allocated.
You can run the chain with a different allocation as well:
./scripts/run.sh --initial-owner-address 002b5d019495996310f81c6a26a4dd9eeb9a3f3be1bac0a9294436713aecc84496Also on default settings, the external subscriber is not run. If you want to connect nuklaivm to an external subscriber, you can do:
./scripts/run.sh --external-subscriber-server-address 127.0.0.1:50051For an example external subscriber, you can refer to https://github.com/Nuklai/nuklaivm-external-subscriber.
Note that these flags also work with ./scripts/run_docker.sh.
The run script uses AvalancheGo's tmpnet to launch a 2 node network with one node's server running at the hardcoded URI: http://127.0.0.1:9650/ext/bc/nuklaivm.
Each default API comes with its own extension. For example, you can get the networkID, subnetID, and chainID by hitting the /coreapi extension:
curl -X POST --data '{
"jsonrpc":"2.0",
"id" :1,
"method" :"hypersdk.network",
"params" : {}
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/nuklaivm/coreapiThis should return the following JSON:
{
"jsonrpc": "2.0",
"result": {
"networkId": 88888,
"subnetId": "yfnUMucMT51SgDQRHS5dGZrHKSLzhp49ReUfp9abfHBhQ4XV2",
"chainId": "2P3GpJ3BDN9u8ejJ9tfqvMy5deub1BevNmt2A9qhAcUWskioqW"
},
"id": 1
}You can also check the balance by doing:
curl -X POST --data '{
"jsonrpc":"2.0",
"id" :1,
"method" :"nuklaivm.balance",
"params" : {"address":"00c4cb545f748a28770042f893784ce85b107389004d6a0e0d6d7518eeae1292d9","asset":"NAI"}
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/nuklaivm/nuklaiapiThis should return the following JSON:
{
"jsonrpc": "2.0",
"result": {
"amount": 853000000000000000
},
"id": 1
}Note: if you run into any issues starting your network, try running the following commands to troubleshoot and create a GitHub issue to report:

killlall avalanchegoNext, you'll need to add the chains you created and the default key to the
nuklai-cli. You can use the following commands from this location to do so:
./build/nuklai-cli key import ed25519 demo.pkIf the key is added correctly, you'll see the following log:

./build/nuklai-cli chain importThis will automatically import the uri with the value http://127.0.0.1:9650/ext/bc/nuklaivm.
If you want to import another chain with its uri, you can do the following:
./build/nuklai-cli chain import "http://127.0.0.1:41177/ext/bc/nuklaivm"You can confirm the chain was imported correctly by running:
./build/morpheus-cli chain infoThis should output something like the following:

./build/nuklai-cli key balanceIf successful, the balance response should look like this:

./build/nuklai-cli key balance 01b27c7ce992cdb7ff039294d7901851902394bb85fa4f3dc4cbb960b07284b7f9Should give output

Because we use bech32 addresses, we can't just put a random string of characters as the recipient (won't pass checksum test that protects users from sending to off-by-one addresses).
./build/nuklai-cli key generate secp256r1Note that we are now generating a key with curve secp256r1 instead of ed25519 like our first account. We can do this because the vm supports three types of keys(ed25519, secp256r1 and bls)
If successful, the nuklai-cli will emit the new address:
created address: 011ddbf62f227dd32deea73b31945d65bb6676cccae6cf0b829dfc21b290387bac
Private Key String(Base64): J5kwBjyvMuvV4PfjTUOO8ZF40Db3KzhFidhH7ER+9Jg=We can also generate a bls key doing
./build/nuklai-cli key generate blsBy default, the nuklai-cli sets newly generated addresses to be the default. We run
the following command to set it back to demo.pk:
./build/nuklai-cli key setYou should see something like this:

set default key: 0There may be times when you just want to generate random nuklaivm addresses that have no associated private key. In theory, there could be a private key that corresponds to any given address, but the probability of such an occurrence is extremely low, especially when dealing with a sufficiently large random space.
However, to be certain that an address does not correspond to any private key, we can construct it in such a way that it falls outside the normal range of addresses generated from private keys.
The vanity address generation process involves creating random blockchain addresses and checking if they start with a specific prefix (e.g., "nuklai"). We generate cryptographically secure random IDs and construct addresses using these IDs. To speed up the search, the process runs in parallel across multiple CPU cores, with each worker testing a batch of addresses. The process continues until an address matching the desired prefix is found.
When you do
./build/nuklai-cli key generate-vanity-address nuklaiThis will put "kiran" as the prefix and use that to generate a new vanity address.
You should see something like:
Using 24 workers to generate vanity address
Vanity Address: ffeb380a5e8b4ee882081e3f0f9b6378cbdb935245f6bd82df13246dae80e5f056We are creating an address that includes the word "nuklaivmvanity" followed by random 19 bytes of data. This kind of address is highly unlikely to be generated from a private key because it does not follow the typical structure of addresses derived from private keys.
Lastly, we trigger the transfer:
./build/nuklai-cli action transferThe nuklai-cli will emit the following logs when the transfer is successful:
address: 00c4cb545f748a28770042f893784ce85b107389004d6a0e0d6d7518eeae1292d9
