Accumulate

Accumulate is a novel blockchain network designed to be hugely scalable while maintaining security. More details

Command Line Interface (CLI)

The CLI lives in ./cmd/accumulated. It can be run directly via go run ./cmd/accumulated ..., which builds to a temporary directory and executes the binary in one go. It can be built via go build ./cmd/accumualted, which creates accumulated or accumulated.exe in the current directory. It can be installed to $GOPATH/bin/accumulated ( GOPATH defaults to $HOME/go) via go install ./cmd/accumulated.

Main TestNet

To initialize node configuration in ~/.accumulate, choose a network from networks/networks.go, and run accumulated init -n <name>.

Once ~/.accumulate is initialized, run accumulated run -n <n> where <n> is the index of the node you want to run. For example, "Arches" has two nodes, index 0 and index 1.

Local TestNet

To set up a testnet on your PC, using localhost addresses, run accumulated testnet -w <config-dir>, e.g. accumulated testnet -w ./nodes.

• -v/--validators sets the number of nodes created, default 3.
• --ip sets the IP address of the first node, default 127.0.1.1. Nodes after the first will increment the IP, e.g. 127.0.1.2.
• --port sets the base port, default 26656. Tendermint P2P will run on the base port, Tendermint RPC on base port + 1, Tendermint GRPC on +2, Accumulate RPC on +3, Accumulate JSONRPC API on +4, and Accumulate REST API on +5.

To run a node in the testnet, run accumulated run -w <dir>/Node<n>, e.g. accumulated run -w ./nodes/Node0.

Code organization

Accumulate is broken into the following components:

• cmd/accumulated - Daemon
• cmd/accumulate - CLI wallet
• config - Daemon configuration types
• internal/abci - ABCI implementation
• internal/api- JSON-RPC v1; Deprecated: use internal/api/v2
• internal/api/v2- JSON-RPC v2
• internal/chain - Transaction validation and processing (aka chain validators)
• internal/cmd/gentypes - Type generator for internal/api and protocol
• internal/encoding - Shared code used by generated types in internal/api and protocol
• internal/genesis - Objects that are created when the node first starts up
• internal/logging - Logging setup
• internal/node - Node configuration, initialization, and execution
• internal/relay - The relay, responsible for relaying transactions to the appropriate BVC; Deprecated: use internal/api/v2
• internal/testing - Test helpers
• internal/url - Accumulate URL parser
• internal/web/static - Embedded web server content
• networks - Accumulate network definitions
• protocol - Protocol types and definitions
• router - Accumulate API
• smt - Stateful Merkle Tree
• types - Data type definitions, used for RPC and persistence; Deprecated: these packages will eventually be moved or replaced, new work should happen elsewhere

Load Test

To load test an Accumulate network, run accumulated testnet --network <name> or accumulated testnet --remote <ip-addr>. These flags can be combined.

• --network adds the first IP of the named or numbered network to the target list.
• --remote adds the given IP to the target list.
• --wallets sets the number of generated wallets.
• --transactions sets the number of generated transactions.
