Method Chain API

This API allows clients to interact with Dijets Method Chain, which acts as a metadata chain maintaining Dijet's Validators set and handles the creation of other blockchains.

Endpoint#

/ext/bc/P

Format#

This API uses the json 2.0 RPC format.

Methods#

`addDelegator`#

Not recommended for use on Mainnet. See warning notice in Keystore API.

Add a delegator to the Primary Network.

A delegator stakes DJT and specifies a validator (the delegatee) to validate on their behalf. The delegatee has an increased probability of being sampled by other validators (weight) in proportion to the stake delegated to them.

The delegatee charges a fee to the delegator; the former receives a percentage of the delegator’s validation reward (if any.) A transaction that delegates stake has no fee.

The delegation period must be a subset of the period that the delegatee validates the Primary Network.

Once you issue the transaction to add a node as a delegator, there is no way to change the parameters. You can’t remove a stake early or change the stake amount, node ID, or reward address. Please make sure you’re using the correct values. If you’re not sure, please reach out to us on Qowalts

Signature:

platform.addDelegator(
    {
        nodeID: string,
        startTime: int,
        endTime: int,

        username: string,
        password: string
    }
) ->
{
    txID: string,
    changeAddr: string
}

nodeID is the DijetsNode ID of the node to delegate to.
startTime is the Unix time when the delegator starts delegating.
endTime is the Unix time when the delegator stops delegating (and staked DJT is returned).
stakeAmount is the amount of nDJT the delegator is staking.
rewardAddress is the address the validator reward goes to, if there is one.
from are the addresses that you want to use for this operation. If omitted, uses any of your addresses as needed.
changeAddr is the address any change will be sent to. If omitted, change is sent to one of the addresses controlled by the user.
username is the user that pays the transaction fee.
password is username‘s password.
txID is the transaction ID

`method.addSubnetValidator`#

Not recommended for use on Mainnet. See warning notice in Keystore API.

Add a validator to a Subnetwork other than the Primary Network. The Validator must validate the Primary Network for the entire duration they validate this Subnetwork.

Signature:

platform.addSubnetValidator(
    {
        nodeID: string,
        subnetID: string,
        startTime: int,
        endTime: int,
        weight: int,
        from: []string, // optional
        changeAddr: string, // optional
        username: string,
        password: string
    }
) ->
{
    txID: string,
    changeAddr: string,
}

nodeID is the node ID of the validator being added to the Subnetwork. This validator must validate the Primary Network for the entire duration that it validates this Subnetwork.
subnetID is the ID of the Subnetwork we’re adding a validator to.
startTime is the Unix time when the validator starts validating the Subnetwork. It must be at or after the time that the validator starts validating the Primary Network
endTime is the Unix time when the validator stops validating the Subnetwork. It must be at or before the time that the validator stops validating the Primary Network.
weight is the validator’s weight used for sampling. If the validator’s weight is 1 and the cumulative weight of all validators in the Subnetwork is 100, then this validator will be included in about 1 in every 100 samples during consensus. The cumulative weight of all validators in the Subnetwork must be at least min-sample-size. For example, if there is only one validator in the Subnetwork, its weight must be at least min-sample-size (default 20). Recall that a validator's weight can't be changed while it is validating, so take care to use an appropriate value.
from are the fund addresses that the user wants to use to pay for this operation. If omitted, use any of user's addresses as needed.
changeAddr is the address any change/left-over of the fund (specified by the from addresses) will be sent to. If omitted, change/left-over is sent to one of the addresses controlled by the user.
username is the user that pays the transaction fee.
password is username‘s password.
txID is the transaction ID.

`method.addValidator`#

Not recommended for use on Mainnet. See warning notice in Keystore API.

Add a validator to the Primary Network. You must stake DJT to do this. If the node is sufficiently correct and responsive while validating, you receive a reward when end of staking period is reached. The validator’s probability of being sampled by other validators during consensus is in proportion to the amount of DJT staked.

The validator charges a fee to delegators; the former receives a percentage of the delegator’s validation reward (if any.) The minimum delegation fee is 2%. A transaction that adds a validator has no fee.

The validation period must be between 2 weeks and 1 year for the Mainnet, and 24 hours and 1 year for Dijets TestNet Testnet.

There is a maximum total weight imposed on validators. This means that no validator will ever have more DJT staked and delegated to it than this value. This value will initially be set to min(5 * amount staked, 3M DJT). The total value on a validator is 3 million DJT.

Note that once you issue the transaction to add a node as a validator, there is no way to change the parameters. You can’t remove stake early or change the stake amount, node ID, or reward address. Please make sure you’re using the correct values. If you’re not sure, please reach out to us on Qowalts

Signature:

platform.addValidator(
    {
        nodeID: string,

        username: string,
        password: string
    }

{
    txID: string,
    changeAddr: string
}

nodeID is the node ID of the validator being added.
startTime is the Unix time when the validator starts validating the Primary Network.
endTime is the Unix time when the validator stops validating the Primary Network (and staked DJT is returned).
stakeAmount is the amount of nDJT the validator is staking.
rewardAddress is the address the validator reward will go to, if there is one.
delegationFeeRate is the percent fee this validator charges when others delegate stake to them. Up to 4 decimal places allowed; additional decimal places are ignored. Must be between 0 and 100, inclusive. For example, if delegationFeeRate is 1.2345 and someone delegates to this validator, then when the delegation period is over, 1.2345% of the reward goes to the validator and the rest goes to the delegator.
from are the addresses that you want to use for this operation. If omitted, uses any of your addresses as needed.
changeAddr is the address any change will be sent to. If omitted, change is sent to one of the addresses controlled by the user.

`method.getUTXOs`#

Gets the UTXOs that reference a given set of addresses.

Signature:

platform.getUTXOs(
    {
        addresses: []string,
        limit: int, // optional
        startIndex: { // optional
            address: string,
            utxo: string
        },
        sourceChain: string, // optional
        encoding: string, // optional
    },
) ->
{
    numFetched: int,
    utxos: []string,
    endIndex: {
        address: string,
        utxo: string
    },
    encoding: string,
}

utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
If startIndex is omitted, will fetch all UTXOs up to limit.
When using pagination (that is when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
encoding specifies the format for the returned UTXOs. Can only be hex when a value is provided.

Example

Suppose we want all UTXOs that reference at least one of P-dijets18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5 and P-dijets1d09qn852zcy03sfc9hay2llmn9hsgnw4tp3dv6.

Since numFetched is less than limit, we know that we are done fetching UTXOs and don’t need to call this method again.

Suppose we want to fetch the UTXOs exported from the Value Chain to the Method Chain in order to build an ImportTx. Then we need to call GetUTXOs with the sourceChain argument in order to retrieve the atomic UTXOs:

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"platform.getUTXOs",
