GET AQUACHAIN

The aquachain command (full node, RPC server, and wallet) is a portable program that doesn't really need an 'installer', you can run it from anywhere. When you first start aquachain you will connect to the peer-to-peer network and start downloading the chain. To change the way aquachain runs, for example testnet, or rpc, use command line flags. (see Usage section)

You should keep backups your keystore files, and regularly check unlocking them. If not using keys, for example an RPC server, use the -nokeys flag.

List all command line flags using the -h flag, or aquachain help [subcommand]

GUI Wallets connect to RPC nodes and offer an easy-to-use interface. Hosting your own RPC server helps you stay more secure and has zero downtime.

COMPILING

Requires Go.

Linux, BSD, Mac OS

If you are reading this from the source tree, you can simply use make, or make all for all tools.

Programs are built to the ./bin/ directory.

Windows

On windows, double-click make.bat to compile aquachain.exe onto your Desktop.

** Patches can be submitted at Github or Gitlab or Mailing List **

To build latest with go, simply use 'go get' and look in $GOPATH/bin:

CGO_ENABLED=0 go get -v -u gitlab.com/aquachain/aquachain/cmd/aquachain

or all tools:

GOBIN=$PWD CGO_ENABLED=0 go get -v gitlab.com/aquachain/aquachain/cmd/...

To see latest release, check git log or:

SYNCHRONIZING

"Imported new chain segment" means you received new blocks from the network. When a single block is imported, the address of the successful miner is printed. When you start seeing one every 4 minutes or so, you know that you are fully synchronized with the network.

USAGE

Create account from the command line: aquachain.exe account new

List accounts from the command line: aquachain.exe account list

Enter AQUA javascript console: aquachain.exe

Start Daemon (geth default): aquachain.exe daemon

See more commands: Wiki

Type help at the AQUA> prompt for common AQUA console commands.

Run aquachain.exe help for command line flags and options.

RPC SERVER

See "RPC" section in ./Documentation folder and online at: https://gitlab.com/aquachain/aquachain/wikis/RPC

Start HTTP JSON/RPC server for local (127.0.0.1) connections only: aquachain -rpc

Start HTTP JSON/RPC server for remote connections, listening on 192.168.1.5:8543, able to be accessed only by 192.168.1.6:

aquachain -rpc -rpchost 192.168.1.5 -allowip 192.168.1.6/32

With no other RPC flags, the -rpc flag alone is safe for local usage (from the same machine).

Security Note about RPC: Please be aware that hosting a public RPC server (0.0.0.0) will allow strangers access to your system. Do not use the -rpcaddr flag unless you absolutely know what you are doing. Consider using a random RPC port, instead of the default 8543.

For hosting public RPC servers, please consider using -nokeys (new!) and implementing rate limiting on http (and, if using, websockets) , either via reverse proxy such as caddyserver or nginx, or firewall.

Recent builds of aquachain include support for the -allowip flag. It is by default, set to 127.0.0.1, which doesn't allow any LAN or WAN addresses access to your RPC methods.

To add IPs, use aquachain -rpc -rpchost 192.168.1.4 -allowip 192.168.1.5/32,192.168.2.30/32

The CIDR networks are comma separated, no spaces. (the /32 after an IP means 'one IP')

RPC Clients

The JSON/RPC server is able to be used with "Web3" libraries for languages such as Python or Javascript.

For compatibility with existing tools, all calls to eth_ methods are translated to aqua_, behind-the-scenes.

Go packages for creating applications that use Aquachain can be found in this repository, under the opt/aquaclient and rpc/rpcclient namespaces. See each package's documentation (godoc) for more information on usage.

Contributing

Aquachain is free open source software and your contributions are welcome.

Some tips and tricks for hacking on Aquachain core:
  • Always gofmt -w -l -s before commiting. If you forget, adding a simple 'gofmt -w -l -s' commit works.
  • Before making a merge request, try make test to run all tests. If any tests pass, the PR can not be merged into the master branch.
  • Rebase: Don't git pull to update your branch. instead, from your branch, type git rebase -i master and resolve any conflicts (do this often and there wont be any!)
  • Prefix commit message with package name, such as "core: fix blockchain"

var NotFound = errors.New("not found")

NotFound is returned by API methods if the requested item does not exist.

Functions

This section is empty.

Types

type CallMsg

type CallMsg struct {
	From     common.Address  // the sender of the 'transaction'
	To       *common.Address // the destination contract (nil for contract creation)
	Gas      uint64          // if 0, the call executes with near-infinite gas
	GasPrice *big.Int        // wei <-> gas exchange ratio
	Value    *big.Int        // amount of wei sent along with the call
	Data     []byte          // input data, usually an ABI-encoded contract method invocation
}

CallMsg contains parameters for contract calls.

type ChainReader

type ChainReader interface {
	BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error)
	BlockByNumber(ctx context.Context, number *big.Int) (*types.Block, error)
	HeaderByHash(ctx context.Context, hash common.Hash) (*types.Header, error)
	HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
	TransactionCount(ctx context.Context, blockHash common.Hash) (uint, error)
	TransactionInBlock(ctx context.Context, blockHash common.Hash, index uint) (*types.Transaction, error)

	// This method subscribes to notifications about changes of the head block of
	// the canonical chain.
	SubscribeNewHead(ctx context.Context, ch chan<- *types.Header) (Subscription, error)
}

ChainReader provides access to the blockchain. The methods in this interface access raw data from either the canonical chain (when requesting by block number) or any blockchain fork that was previously downloaded and processed by the node. The block number argument can be nil to select the latest canonical block. Reading block headers should be preferred over full blocks whenever possible.

The returned error is NotFound if the requested item does not exist.

type ChainStateReader

type ChainStateReader interface {
	BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)
	StorageAt(ctx context.Context, account common.Address, key common.Hash, blockNumber *big.Int) ([]byte, error)
	CodeAt(ctx context.Context, account common.Address, blockNumber *big.Int) ([]byte, error)
	NonceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (uint64, error)
}

ChainStateReader wraps access to the state trie of the canonical blockchain. Note that implementations of the interface may be unable to return state values for old blocks. In many cases, using CallContract can be preferable to reading raw contract storage.

type ChainSyncReader

type ChainSyncReader interface {
	SyncProgress(ctx context.Context) (*SyncProgress, error)
}

ChainSyncReader wraps access to the node's current sync status. If there's no sync currently running, it returns nil.

type ContractCaller

type ContractCaller interface {
	CallContract(ctx context.Context, call CallMsg, blockNumber *big.Int) ([]byte, error)
}

A ContractCaller provides contract calls, essentially transactions that are executed by the EVM but not mined into the blockchain. ContractCall is a low-level method to execute such calls. For applications which are structured around specific contracts, the abigen tool provides a nicer, properly typed way to perform calls.

type FilterQuery

type FilterQuery struct {
	FromBlock *big.Int         // beginning of the queried range, nil means genesis block
	ToBlock   *big.Int         // end of the range, nil means latest block
	Addresses []common.Address // restricts matches to events created by specific contracts

	// The Topic list restricts matches to particular event topics. Each event has a list
	// of topics. Topics matches a prefix of that list. An empty element slice matches any
	// topic. Non-empty elements represent an alternative that matches any of the
	// contained topics.
	//
	// Examples:
	// {} or nil          matches any topic list
	// {{A}}              matches topic A in first position
	// {{}, {B}}          matches any topic in first position, B in second position
	// {{A}}, {B}}        matches topic A in first position, B in second position
	// {{A, B}}, {C, D}}  matches topic (A OR B) in first position, (C OR D) in second position
	Topics [][]common.Hash
}

FilterQuery contains options for contract log filtering.

type GasEstimator

type GasEstimator interface {
	EstimateGas(ctx context.Context, call CallMsg) (uint64, error)
}

GasEstimator wraps EstimateGas, which tries to estimate the gas needed to execute a specific transaction based on the pending state. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default.

type GasPricer

type GasPricer interface {
	SuggestGasPrice(ctx context.Context) (*big.Int, error)
}

GasPricer wraps the gas price oracle, which monitors the blockchain to determine the optimal gas price given current fee market conditions.

type LogFilterer

type LogFilterer interface {
	FilterLogs(ctx context.Context, q FilterQuery) ([]types.Log, error)
	SubscribeFilterLogs(ctx context.Context, q FilterQuery, ch chan<- types.Log) (Subscription, error)
}

LogFilterer provides access to contract log events using a one-off query or continuous event subscription.

Logs received through a streaming query subscription may have Removed set to true, indicating that the log was reverted due to a chain reorganisation.

type PendingContractCaller

type PendingContractCaller interface {
	PendingCallContract(ctx context.Context, call CallMsg) ([]byte, error)
}

PendingContractCaller can be used to perform calls against the pending state.

type PendingStateEventer

type PendingStateEventer interface {
	SubscribePendingTransactions(ctx context.Context, ch chan<- *types.Transaction) (Subscription, error)
}

A PendingStateEventer provides access to real time notifications about changes to the pending state.

type PendingStateReader

type PendingStateReader interface {
	PendingBalance(ctx context.Context, account common.Address) (*big.Int, error)
	PendingStorage(ctx context.Context, account common.Address, key common.Hash) ([]byte, error)
	PendingCode(ctx context.Context, account common.Address) ([]byte, error)
	PendingNonce(ctx context.Context, account common.Address) (uint64, error)
	PendingTransactionCount(ctx context.Context) (uint, error)
}

A PendingStateReader provides access to the pending state, which is the result of all known executable transactions which have not yet been included in the blockchain. It is commonly used to display the result of ’unconfirmed’ actions (e.g. wallet value transfers) initiated by the user. The PendingNonceAt operation is a good way to retrieve the next available transaction nonce for a specific account.

type Subscription

type Subscription interface {
	// Unsubscribe cancels the sending of events to the data channel
	// and closes the error channel.
	Unsubscribe()
	// Err returns the subscription error channel. The error channel receives
	// a value if there is an issue with the subscription (e.g. the network connection
	// delivering the events has been closed). Only one value will ever be sent.
	// The error channel is closed by Unsubscribe.
	Err() <-chan error
}

Subscription represents an event subscription where events are delivered on a data channel.

type SyncProgress

type SyncProgress struct {
	StartingBlock uint64 // Block number where sync began
	CurrentBlock  uint64 // Current block number where sync is at
	HighestBlock  uint64 // Highest alleged block number in the chain
	PulledStates  uint64 // Number of state trie entries already downloaded
	KnownStates   uint64 // Total number of state trie entries known about
}

SyncProgress gives progress indications when the node is synchronising with the Aquachain network.

type TransactionReader

type TransactionReader interface {
	// TransactionByHash checks the pool of pending transactions in addition to the
	// blockchain. The isPending return value indicates whether the transaction has been
	// mined yet. Note that the transaction may not be part of the canonical chain even if
	// it's not pending.
	TransactionByHash(ctx context.Context, txHash common.Hash) (tx *types.Transaction, isPending bool, err error)
	// TransactionReceipt returns the receipt of a mined transaction. Note that the
	// transaction may not be included in the current canonical chain even if a receipt
	// exists.
	TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
}

TransactionReader provides access to past transactions and their receipts. Implementations may impose arbitrary restrictions on the transactions and receipts that can be retrieved. Historic transactions may not be available.

Avoid relying on this interface if possible. Contract logs (through the LogFilterer interface) are more reliable and usually safer in the presence of chain reorganisations.

The returned error is NotFound if the requested item does not exist.

type TransactionSender

type TransactionSender interface {
	SendTransaction(ctx context.Context, tx *types.Transaction) error
}

TransactionSender wraps transaction sending. The SendTransaction method injects a signed transaction into the pending transaction pool for execution. If the transaction was a contract creation, the TransactionReceipt method can be used to retrieve the contract address after the transaction has been mined.

The transaction must be signed and have a valid nonce to be included. Consumers of the API can use package accounts to maintain local private keys and need can retrieve the next available nonce using PendingNonceAt.
