Value Chain API

The Value Chain is Dijets native chain and platform for creating and trading smart digital assets. It is an instance of Dijets Virtual Machine (DVM). This API allows clients to create and trade assets on the Value Chain and on other instances of Dijets Virtual Machine.

Format#

The Value Chain API uses the standard json 2.0 RPC format. For more information on making JSON RPC calls, see here.

Endpoints#

/ext/bc/X to interact with the Value Chain.

/ext/bc/blockchainID to interact with other Dijets Virtual Machine instances, where blockchainID is the ID of a blockchain running the VM.

Methods#

Create Genesis Byte representation#

Given a JSON representation of this Virtual Machine’s genesis state, create the byte representation of that state.

Endpoint

This call is made to Dijets Virtual Machine's static API endpoint:

/ext/vm/avm

Signature:

avm.buildGenesis({
    networkID: int,
    genesisData: JSON,
    encoding: string, //optional
}) -> {
    bytes: string,
    encoding: string,
}

Encoding specifies the encoding format to use for arbitrary bytes, that is the genesis bytes that are returned. Can only be hex when a value is provided.

genesisData has this form:

{
"genesisData" :
    {
        "assetAlias1": {               // Each object defines an asset
            "name": "rogue",

Get all Transactions for an Address#

Returns all transactions that change the balance of the given address. A transaction is said to change an address's balance if either is true:

• A UTXO that the transaction consumes was at least partially owned by the address.
• A UTXO that the transaction produces is at least partially owned by the address.

Signature:

avm.getAddressTxs({
    address: string,

  "id": 1
}

Where:

• credentials is a list of this transaction's credentials. Each credential proves that this transaction's creator is allowed to consume one of this transaction's inputs. Each credential is a list of signatures.
• unsignedTx is the non-signature portion of the transaction.
• networkID is the ID of the network this transaction happened on. (Dijets Mainnet is 1.)
• blockchainID is the ID of the blockchain this transaction happened on. (Dijets Mainnet Value Chain is hgBiUrBJkih9eoPkLtNaJKJQK8Fc2nmR6yuqkh9BmgNY2dJ3Y.)
• Each element of outputs is an output (UTXO) of this transaction that is not being exported to another chain.
• Each element of inputs is an input of this transaction which has not been imported from another chain.
• Import Transactions have additional fields sourceChain and importedInputs, which specify the blockchain ID that assets are being imported from, and the inputs that are being imported.
• Export Transactions have additional fields destinationChain and exportedOutputs, which specify the blockchain ID that assets are being exported to, and the UTXOs that are being exported.

An output contains:

• assetID: The ID of the asset being transferred. (The Mainnet Djtx ID is wjcHr7ng1qPXeJm5Mh3HzQxqz2S9AGo9UVP78jxh5zfirZxY7.)
• fxID: The ID of the FX this output uses.
• output: The FX-specific contents of this output.

Most outputs use the secp256k1 FX, look like this:

{
  "assetID": "wjcHr7ng1qPXeJm5Mh3HzQxqz2S9AGo9UVP78jxh5zfirZxY7",
  "fxID": "spdxUxVJQbX85MGxMHbKw1sHxMnSqJ3QBzDyDYEP3h6TLuxqQ",

    "amount": 1530084210,
    "locktime": 0,
    "threshold": 1
  }
}

The above output can be consumed after Unix time locktime by a transaction that has signatures from threshold of the addresses in addresses.

dvm.getTxStatus#

Get the status of a transaction sent to the network.

Signature:

avm.getTxStatus({txID: string}) -> {status: string}

status is one of:

• Accepted: The transaction is (or will be) accepted by every node
• Processing: The transaction is being voted on by this node
• Rejected: The transaction will never be accepted by any node in the network
• Unknown: The transaction hasn’t been seen by this node

Example Call:

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"avm.getTxStatus",
    "params" :{

    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/X

Example Response:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "status": "Accepted"
  }
}

dvm.getUTXOs#

Gets the UTXOs that reference a given address. If sourceChain is specified, then it will retrieve the atomic UTXOs exported from that chain to the X Chain.

Signature:

avm.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
    },
    sourceChain: string, //optional
    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 (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 sets 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 X-dijets18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5 and X-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 Method Chain to the Value 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" :"avm.getUTXOs",
    "params" :{
        "addresses":["X-dijets18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5", "X-dijets1d09qn852zcy03sfc9hay2llmn9hsgnw4tp3dv6"],
        "limit":5,
        "sourceChain": "P",
        "encoding": "hex"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/X

This gives response:

  "jsonrpc": "2.0",
  "result": {
    "numFetched": "1",
    "utxos": [
      "0x00001f989ffaf18a18a59bdfbf209342aa61c6a62a67e8639d02bb3c8ddab315c6fa0000000039c33a499ce4c33a3b09cdd2cfa01ae70dbf2d18b2d7d168524440e55d550088000000070011c304cd7eb5c0000000000000000000000001000000013cb7d3842e8cee6a0ebd09f1fe884f6861e1b29c83497819"

    to: string,
    sourceChain: string,
    username: string,
    password: string,
}) -> {txID: string}

• to is the address the DJTX is sent to. This must be the same as the to argument in the corresponding call to the Method Chain’s exportDJTX or Utility Chain's export.
• sourceChain is the ID or alias of the chain the DJTX is being imported from. To import funds from the Utility Chain, use "C".
• username is the user that controls to.
• txID is the ID of the newly created atomic transaction.
