About this release

This is a maintenance release. It contains stability improvements so all users are encouraged to upgrade.

This release:

  • Adds operators mod, ++, bsl, bsr, and ^ to the Sophia compiler.

  • Adds function String.sha3 to the Sophia compiler.

  • Changes cuckoo miner config and processing to allow multiple simultaneous miners. This impacts mining configuration:

    • changes mining > cuckoo > miner param to mining > cuckoo > miners and makes mining > cuckoo > miner param deprecated

    • moves mining > cuckoo > miner > edge_bits param to mining > cuckoo section

  • Adds Events to the Sophia compiler

  • Adds builtin functions Int.to_str and Address.to_str to the Sophia compiler

  • Adds native Windows build support.

    • Follow the instructions from /docs/build-windows.md to build and run a node on Windows.

  • Improves the handling of errors in contract create and contract call transactions.

  • Enhances the Sophia compiler, that now correctly rejects some programs that resulted in incorrect bytecode before.

The Sophia compiler has been moved to a separate repository.

This release is backward compatible with v1.1.* and v1.0.*.

The instructions below describe:

Retrieve the software for running a node

You can run a node by either:

The user configuration is documented in the wiki. For specifying configuration using the Docker image, please refer to its documentation.

The node user API is documented:

  • HTTP API endpoints are specified online in swagger.yaml;

    • A JSON version of the same specification is located in the node at path lib/aehttp-*/priv/swagger.json (you will need to amend the wildcard * placeholder in the path with the version).

    • The JSON version can be obtained from a running node using the endpoint /api.

    • An interactive visualization of the same specification is available online.

  • WebSocket API endpoints are specified online;

  • The intended usage of the user API (HTTP and WebSocket) is documented online.

Install node

The instructions for installing a node using a release binary are in the dedicated separate document.

For installation of a node using the Docker image, please refer to its documentation online.

Inspect Roma network

Here are example nodes that can be used to inspect current top block and see information about e.g. height or target:

  • http://35.178.61.73:3013/v2/blocks/top

  • http://35.177.192.219:3013/v2/blocks/top

  • http://18.136.37.63:3013/v2/blocks/top

  • http://52.220.198.72:3013/v2/blocks/top

Join the testnet

This section describes how to run a node as part of the testnet - the public test network of nodes - by using the release binary.

For running a node as part of the testnet by using the Docker image, please consult its documentation in addition to this section.

Testnet seed nodes

In order to join testnet reconfigure seed nodes in the release package:

  • aenode://pp_QU9CvhAQH56a2kA15tCnWPRJ2srMJW8ZmfbbFTAy7eG4o16Bf@52.10.46.160:3015

  • aenode://pp_27xmgQ4N1E3QwHyoutLtZsHW5DSW4zneQJ3CxT5JbUejxtFuAu@13.250.162.250:3015

  • aenode://pp_nt5N7fwae3DW8Mqk4kxkGAnbykRDpEZq9dzzianiMMPo4fJV7@18.130.148.7:3015

Inspect the testnet

The core nodes of the public test network are accessible from the Internet.

Information, e.g. height, of the top block of the longest chain as seen by these core nodes of the testnet can be obtained by opening in the browser any of the following URLs:

  • http://52.10.46.160:3013/v2/blocks/top

  • http://13.250.162.250:3013/v2/blocks/top

  • http://18.130.148.7:3013/v2/blocks/top
