Activeledger guide

This guide is the least you need to know to run, operate and use Activeledger. It is for the person who has to stand up a network, keep it running, and send it work.

Activeledger is a distributed ledger: a shared record kept by several computers, where a change is accepted only when enough of them agree. Application logic lives in contracts you write in TypeScript. If you have never seen it before, read Concepts first. It takes a few minutes and makes every other page shorter.

Where to start

Run a node

1. Install and build
2. Run a first node, then a small network
3. config.json: what you need to set
4. How many nodes, consensus, builds and upgrades

3. The HTTP endpoints you need

Write a contract

1. What a contract is
2. Writing a contract
3. The contract API you will use
4. Deploy, update, lock and unlock
5. Running a contract

Run a hybrid

1. What a hybrid node is and when to use one
2. Set up and run a hybrid
3. Operating hybrids
4. Writing contracts that also run on hybrids

Restore a node

1. Restoring a node
2. The activerestore command

Three programs

Program	What it does
activeledger	Runs a node. This is the only one you must run.
activerestore	Heals a node that has fallen behind or started empty. A node starts it for you by default.
activehybrid	Runs a hybrid: a lighter node that follows the network but does not vote. Optional.
