Blockchain

Used to get the latest block and supply of the blockchain.

Get blockchain data

LinkedTreeMap<String, Object> blockchain = connection2.api().blockchain.all();

>>> LinkedTreeMap<String, Object>

Blocks

This service API grants access to the blocks resource. A block is a signed set of transactions created by a delegate and permanently committed to the ARK blockchain.

It is not possible to POST a block through the public API. Relay Nodes accept only blocks posted by a delegate at the correct time through the internal API.

List All Blocks

LinkedTreeMap<String, Object> blocks = connection.api().blocks.all();

>>> LinkedTreeMap<String, Object>

Retrieve a Block

LinkedTreeMap<String, Object> block = connection.api().blocks.show("validBlockId");

>>> LinkedTreeMap<String, Object>

Retrieve first block

LinkedTreeMap<String, Object> block = connection2.api().blocks.first();

>>> LinkedTreeMap<String, Object>

Retrieve last block

LinkedTreeMap<String, Object> block = connection2.api().blocks.last();

>>> LinkedTreeMap<String, Object>

List All Transactions of a Block

LinkedTreeMap<String, Object> blockTransactions = connection.api().blocks.transactions("validBlockId");

>>> LinkedTreeMap<String, Object>

Search All Blocks

LinkedTreeMap<String, Object> searchedBlocks = connection.api().blocks.search(new HashMap<>());

>>> LinkedTreeMap<String, Object>

Bridgechains

This service API grants access to the bridgechain resource. This can be used to access all registered bridgechains on the network.

List all bridgechains

LinkedTreeMap<String, Object> bridgechains = connection2.api().bridgechains.all();

Businesses

This service API grants access to the business resource. This can be used to access all registered businesses on the network.

List all businesses

LinkedTreeMap<String, Object> businesses = connection2.api().businesses.all();

>>> LinkedTreeMap<String, Object>

Retrieve a businesses

LinkedTreeMap<String, Object> businesses = connection2.api().businesses.show("wallet address");

>>> LinkedTreeMap<String, Object>

Retrieve all bridgechains of a business

LinkedTreeMap<String, Object> bridgechains = connection2.api().businesses.showBridgechains("D991ZqskaGWMDu9kpfpJr5LRssV7ek981k");

Delegates

The client SDK can be used to query the delegate resource.

A delegate is a regular wallet that has broadcasted a registration transaction, acquired a sufficient number of votes, and has a Relay Node configured to forge new blocks through a forger module. At any time only 51 delegates are active. They are cost-efficient miners running the ARK network.

Voters are wallets which have broadcasted a vote transaction on a delegate. A vote remains active until an un-vote transaction is sent (it does not have to be recast unless a wallet wishes to change from delegate). Voting for a delegate does not give the delegate access to the wallet nor does it lock the coins in it.

List All Delegates

LinkedTreeMap<String, Object> delegates = connection.api().delegates.all();

>>> LinkedTreeMap<String, Object>

Retrieve a Delegate

LinkedTreeMap<String, Object> delegate = connection.api().delegates.show("validDelegateId");

>>> LinkedTreeMap<String, Object>

List All Blocks of a Delegate

LinkedTreeMap<String, Object> delegateBlocks = connection.api().delegates.blocks("validDelegateId");

>>> LinkedTreeMap<String, Object>

List All Voters of a Delegate

LinkedTreeMap<String, Object> delegateVoters = connection.api().delegates.voters("validDelegateId");

>>> LinkedTreeMap<String, Object>

Search delegates

LinkedTreeMap<String, Object> delegates = connection2.api().delegates.search(new HashMap<>());

>>> LinkedTreeMap<String, Object>

Locks

This service API grants access to the lock resource. This can be used to access all locks initiated for wallets.

List all locks

LinkedTreeMap<String, Object> locks = connection2.api().locks.all();

>>> LinkedTreeMap<String, Object>

Retrieve a lock

LinkedTreeMap<String, Object> lock = connection2.api().locks.show("lock id");

>>> LinkedTreeMap<String, Object>

Search unlocked locks

LinkedTreeMap<String, Object> unlockedLocks = connection2.api().locks.searchUnlocked(new HashMap<>());

>>> LinkedTreeMap<String, Object>

Search locks

LinkedTreeMap<String, Object> locks = connection2.api().locks.search(new HashMap<>());

>>> LinkedTreeMap<String, Object>

Node

The ARK network consists of different anonymous nodes (servers), maintaining the public ledger, validating transactions and blocks and providing APIs. The node resource allows for querying the health and configurations of the node used by the instantiated client.

Retrieve the Configuration

LinkedTreeMap<String, Object> nodeConfiguration = connection.api().node.configuration();

>>> LinkedTreeMap<String, Object>

Retrieve the Status

LinkedTreeMap<String, Object> nodeStatus = connection.api().node.status();

>>> LinkedTreeMap<String, Object>

Retrieve the Syncing Status

LinkedTreeMap<String, Object> nodeSyncingStatus = connection.api().node.syncing();

>>> LinkedTreeMap<String, Object>

Retrieve the Fees

LinkedTreeMap<String, Object> fees = connection2.api().node.fees(days);

>>> LinkedTreeMap<String, Object>

Debug

LinkedTreeMap<String, Object> debug = connection2.api().node.debug();

>>> LinkedTreeMap<String, Object>

Peers

Each node is connected to a set of peers, which are Relay or Delegate Nodes as well. The peers resource provides access to all peers connected to our node.

Peers have made their Public API available for use; however for mission-critical queries and transaction posting you should use a node which is under your control. We provide a guide to setting up a Relay Node here.

List All Peers

LinkedTreeMap<String, Object> peers = connection.api().peers.all();

>>> LinkedTreeMap<String, Object>

Retrieve a Peer

LinkedTreeMap<String, Object> peer = connection.api().peers.show("validIpAddress");

>>> LinkedTreeMap<String, Object>

Rounds

This service API grants access to the round resource. This can be used to access all round information for the network.

List Delegates for a Round

LinkedTreeMap<String, Object> delegates = connection2.api().rounds.delegates(numberOfARound);

>>> LinkedTreeMap<String, Object>

Transactions

The heart of any blockchain is formed by its transactions; state-altering payloads signed by a wallet. Most likely you will be querying for transactions most often, using the transaction resource.

A transaction is the only object which may be posted by a non-delegate. It requires a signature from a wallet containing a sufficient amount of ARK.

Create a Transaction

LinkedTreeMap<String, Object> transaction = connection.api().transactions.create(new ArrayList<>());

>>> LinkedTreeMap<String, Object>

Retrieve a Transaction

LinkedTreeMap<String, Object> transaction = connection.api().transactions.show("validTxId");

LinkedTreeMap<String, Object> unconfirmedTransactions = connection.api().transactions.allUnconfirmed();

echo gettype($unconfirmedTransactions);

>>> LinkedTreeMap<String, Object>

Get Unconfirmed Transaction

echo gettype($unconfirmedTransaction);

>>> LinkedTreeMap<String, Object>

Search Transactions

LinkedTreeMap<String, Object> searchedTransactions = connection.api().transactions.search(new HashMap<>());

>>> LinkedTreeMap<String, Object>

List Transaction Types

LinkedTreeMap<String, Object> transactionTypes = connection.api().transactions.types();

>>> LinkedTreeMap<String, Object>

LinkedTreeMap<String, Object> schemas = connection2.api().transactions.schemas();

A vote is a transaction sub-type, where the asset field contains a votes object and the transaction.type is 3.

List All Votes

LinkedTreeMap<String, Object> votes = connection.api().votes.all();

>>> LinkedTreeMap<String, Object>

Retrieve a Vote

LinkedTreeMap<String, Object> actual = connection.api().votes.show("validVoteId");

>>> LinkedTreeMap<String, Object>
