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

$blocks = $connection->blocks()->all();
echo gettype($blocks);
>>> array

Retrieve a Block

$block = $connection->blocks()->show('validBlockId');
echo gettype($block);
>>> array

List All Transactions of a Block

$blockTransactions = $connection->blocks()->transactions('validBlockId');
echo gettype($blockTransactions);
>>> array

Search All Blocks

$searchedBlock = $connection->blocks()->search(['address' => 'validAddress']);
echo gettype($searchedBlock);
>>> array


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

A delegate is a regular wallet that has broadcast 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 broadcast 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

$delegates = $connection->delegates()->all();
echo gettype($delegates);
>>> array

Retrieve a Delegate

$delegate = $connection->delegates()->show('validDelegateId');
echo gettype($delegate);
>>> array

List All Blocks of a Delegate

$delegateBlocks = $connection->delegates()->blocks('validDelegateId');
echo gettype($delegateBlocks);
>>> array

List All Voters of a Delegate

$delegates = $connection->delegates()->voters('validDelegateId');
echo gettype($delegates);
>>> array


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

$nodeConfiguration = $connection->node()->configuration();
echo gettype($nodeConfiguration);
>>> array

Retrieve the Status

$nodeStatus = $connection->node()->status();
echo gettype($nodeStatus);
>>> array

Retrieve the Syncing Status

$nodeSyncingStatus = $connection->node()->syncing();
echo gettype($nodeSyncingStatus);
>>> array

Retrieve the Fees

$nodeFees = $connection->node()->fees();
echo gettype($nodeFees);
>>> array


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

$peers = $connection->peers()->all();
echo gettype($peers);
>>> array

Retrieve a Peer

$peer = $connection->peers()->show('validIpAddress');
echo gettype($peer);
>>> array


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

$transactions = $connection->transactions()->create(['transactions' => []]);
echo gettype($transactions);
>>> array

Retrieve a Transaction

$transaction = $connection->transactions()->show('validTransactionId');
echo gettype($transaction);
>>> array

List All Transactions

$transactions = $connection->transactions()->all();
echo gettype($transactions);
>>> array

List All Unconfirmed Transactions

$unconfirmedTransactions = $connection->transactions()->allUnconfirmed();
echo gettype($unconfirmedTransactions);
>>> array

Get Unconfirmed Transaction

$unconfirmedTransaction = $connection->transactions()->showUnconfirmed('validUnconfirmedTransactionsId');
echo gettype($unconfirmedTransaction);
>>> array

Search Transactions

$transactions = $connection->transactions()->search(['amount' => 1]);
echo gettype($transactions);
>>> array

List Transaction Types

$transactionsTypes = $connection->transactions()->types();
echo gettype($transactionsTypes);
>>> array


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

List All Votes

$votes = $connection->votes()->all();
echo gettype($votes);
>>> array

Retrieve a Vote

$vote = $connection->votes()->show('validTransactionId');
echo gettype($vote);
>>> array


The wallet resource provides access to:

  • Wallets.
  • Incoming and outgoing transactions per wallet.
  • Each wallet’s votes.

Retrieve All Wallets

$wallets = $connection->wallets()->all();
echo gettype($wallets);
>>> array

Retrieve a Wallet

$wallet = $connection->wallets()->show('validWalletId');
echo gettype($wallet);
>>> array

List All Transactions of a Wallet

$walletTransactions = $connection->wallets()->transactions('validWalletId');
echo gettype($walletTransactions);
>>> array

List All Received Transactions of a Wallet

$walletReceivedTransactions = $connection->wallets()->receivedTransactions('validWalletId');
echo gettype($walletReceivedTransactions);
>>> array

List All Sent Transactions of a Wallet

$walletSentTransactions = $connection->wallets()->sentTransactions();
echo gettype($walletSentTransactions);
>>> array

List All Votes of a Wallet

$walletVotes = $connection->wallets()->votes('validWalletId');
echo gettype($walletVotes);
>>> array

List All Top Wallets

$topWallets = $connection->wallets()->top();
echo gettype($topWallets);
>>> array

Search All Wallets

$wallet = $connection->wallets()->search(['address' => 'validAddress']);
echo gettype($wallet);
>>> array
