Biweekly update 8th October — 22nd October

Hey, æternists! We are delighted to provide you with all the recent news happening on the development and social side of æternity. The past two weeks were especially eventful, as all the dev teams have been working hard while moving forward on “the road to Lima.” Their focus last week was on the upcoming token migration. Thus, the solution is developed and is currently tested on the testnet with no issues occurred. They also managed to make some improvements to the existing tools like æproject, Contracts æpp, and Playground. New versions with Lima support are available for all tools; æproject version 1.0.3 is released. The team has provided fixes to some community issues that were reported in the forum and GitHub. Importantly, the support for the Lima hardfork was provided. Other milestones include local node version being updated to 5.0.0-rc5, new local compiler version 4.0.0, JsSDk upgraded to 6.0.0 version, and new contracts æpp version released. Moreover, the new State Channels bi-weekly development update featured State Channel UAT test suite, integration test improvements, a port of æUniverse demo changes to master, and system test hardening. The AirGap team published an update on the Wallet, Coin Library and Vault, where they worked on a bug that prevented Base æpp — AirGap Vault interaction. Python and JS SDK 6.0.0 for aeternity are now out.

Another essential aspect of ælife is a social activity. The team and the community are still reflecting on amazing æternity Universe One, that “was a kickoff one would never forget’’, with its brilliant presentations and panels; find all the recordings of the fantastic talks and summaries in the update. In addition, don’t miss out on cool short interviews by Caribbean Blockchain Network and Pablo Coirolo talking about the future of æternity in the Americas, including the collaboration with the CIE ORT University and the introduction of real-world use cases of the technology. The community and the number of subscribers in social networks tend to increase. Some astonishing news from æventures as a conclusion: Startups from more than 100 cities around the world applied for Starfleet 3! Let the æcosystem grow! Stay tuned!

“The signalling using the key block header field info is backward compatible, as the meaning of the value of such field is not under consensus. The activation of the new consensus protocol based on miner signalling is meant to be a temporary measure during the time interval when the new protocol may be activated on the network while the node is running. Once the network reasonably settles on whether to activate the new consensus protocol, the user is meant to enforce such decision on the eventual node restart either by configuration or by upgrading the node to a new version.”

  4. Aeproject issue with return code 0 for test commands and CI tools fixed
  5. Allow spend with the deployer
  6. Fixed issue with interruption when calling aeproject init command
  7. Issue with travis builds were fixed

Changelog:

  1. Fixes unsupported node version 5.0.0-rc4 (#159)
  2. Language names written in full (#145)
  3. UI fixes (#157)
  4. Add deployed token to Token Registry (#153)
  5. Ask user to add token in the registry (#154)

Off-chain pinned environment

Design: PR #406

Implementation: PR #2746

This change provides SC participants with the possiblitity to pin the on-chain environment in their requests to the off-chain updates execution. It is an instrumental tool to manage rise and ensure expectations are met when performing updates.

State cache encryption

Design: PR #396

Implementation: PR #2630, PR #2803

This change adds on-disk encryption of the state cache which prevents certain attacks on untrusted SC nodes. While the code of the functionality is kept, the feature has been disabled for 5.0.0-rc.3 to allow an improved version to be released as part of 5.1.0.

Making client reconnect more flexible

Implementation: PR #2785, PR #2790

The various options for re-connecting to a running channel have been consolidated to reduce the complexity for the client and improve reliability of the implementation.

Improve and fix tests

Implementation: PR #2767, PR #2768, PR #2789, PR #2792

Various improvements to the SC integration tests and node system tests which involve SCs.

Other improvements

Implementation: PR #2757, PR #2759

Improved logging and refactoring of the aesc_offchain_update versioning.

State Channel UAT Test Suite

Implementation: PR #13, PR #14

The test suite has been heavily extended leading up to the AE Universe One Conference which helped identifying protocol issues and verifying the fixes which are part of the changes described above. New changes will involve moving towards a repeatable test setup which can be integrated into our CI.

Port of AE Universe Demo Changes to master

Implementation: PR #2801

The accumulated changes which were previously made to a dedicated branch have been ported to the master branch. Thus the next minor release v5.1.0 will include these changes. For more information on these changes take a look at the report from End of September 2019.

System Test Hardening

Implementation: PR #2832, PR #2865, PR #2905

The aeternity project runs a set of long-running system tests to stress test the latest master branch. They’ve identified a few bugs in the test setup as well as actual bugs in the implementation which have been dealt with. The result are more stable system tests which indicate a stabilized implementation.

Integration Test Improvements

Implementation: PR #2810, PR #2824, PR #2827, PR #2838, PR #2844, PR #2875

The integration tests are continuously being improved. More tests were added and existing tests modified to improve coverage and fix incorrect assumptions. Most changes have also led to simple bug-fixes in the process.

Refactor FSM message log and ensure early start of chain watcher

Implementation: PR #2872, PR #2879

The order of log messages has been fixed. Moreover, the requirement, that the chain watcher is started before performing actions which depend on it, is handled by providing a helper function to ensure the ordering. This prevents race conditions which were seen before.

Fix client re-establish notification when connecting to existing channel

Issue: #2854

Implementation: PR #2902

The channel_id was missing in the report which was confusing and required clients to wait longer for the id to be known. This has been fixed.

Unify the WS and FSM client messages

Implementation: PR #2833

This PR unifies the info reports sent from the WS client and the FSM.

This results in a reduction of the amount of data copied between processes when opening a channel and removes gproc from the FSM suite when opening a channel.

State Channel UAT Test Suite

Implementation: PR #15, PR #16, PR #18

The UAT has moved towards using the ExUnit testing framework which is a pre-requisite for setting up CI. The goal is to keep the UAT and feedback from it as close to the aeternity master branch as possible as well as offload

  • AEX-draft 12 off chain state. This expansion points out possibility of using blockchain for maintenance off chain state. You can use transaction payload to build off-chain state (most likely when it’s small). You can use it to validate off chain data using hash in payload. It does not enforce any communication protocol, besides:
  1. using specific zero spend transaction to yourself
  2. proposing to zip json payload of the transaction

It is probably one of the most common usages of blockchain, e.g. in Proof of Existence.

AEX standardizes way to emit data and reminds about this possibility, instead, growing on-chain state.

AirGap Wallet

Changed the date of the message when migrated tokens will be available to end of October.

AirGap Vault

Worked on a bug that prevented Base Aepp <=> AirGap Vault interaction

AirGap Coin Library

Worked on a new serializer that allows messages to be encoded in a more efficient way (eg. for QR codes)

  • æternity crypto foundation graces æternity Universe One — “The æternity Universe One conference was quite the adrenaline rush and we were absolutely thrilled to be part of it!”

Here is a quick summary of the presentations made by the æternity crypto foundation at the æternity Universe One Conference last Sept 20–21, held in La Fabrika and Paralelni Polis in Prague.

Marion Vogel, the President and one of æternity’s founding forces, opened the introduction panel with visionary words from cypherpunk legend Tim May and his crypto manifesto. Marion shared the leading principles and values we all commit to as part of the foundation. To sum up:

  1. The æternity Crypto Foundation commits to support open-source blockchain technology development, and continues to push for further decentralization.
  2. The æternity crypto foundation is an advocate of inclusion and expanding æternity’s developer force is one of the major priorities. Everyone is welcome to apply for a grant.
  3. The foundation supports and interacts proactively with the æternity ecosystem. Part of the foundation’s activities include engaging with Starfleet startups, and providing funding support for the aembassador program.

Check out Marions talk at the æternity Universe One Conference. — A friendly reminder about core values and introduction to the æternity Crypto Foundation.

In a panel moderated by Development and Technical Marketing Manager Pegah Ghojavand, the Board Members shared valuable insights about the foundation’s origin, their motivation to join the Board, and the foundation’s main priorities.

“Open-source blockchain technology is a public good that we continuously want to support and take care of,” Marion explains, asserting this as one of the reasons for establishing the foundation.

“We need to do it in a sustainable way,” adds Emin.

“Open-source development, as any software development, is an ongoing process. In order to be on the top of the industry and lead innovations, you need constant work and resources. The aeternity crypto foundation is doing its best to provide this sustainability. For example, with the BRI we can support developers in the long run. From the tech side, the open-source foundation is focusing on maintaining and improving the protocol and its features.”

Upcoming events:

  1. Developing æpps on æternity Blockchain using Sophia Language Workshop — November 11–13, 2019 | Berlin

Roadmap

  1. The next scheduled hardfork of the æternity protocol will happen in September with the Lima Release (The Mainnet is coming on 30th of October)
  2. Lima will introduce the Fast æternity Transaction Engine (FATE), æternity’s customized virtual machine.
  3. A governance mechanism based on a Sophia smart contract will be introduced and will make it easier for the community to launch governance votes. Delegated voting and a signaling mechanism for hardfork activation will become available. A governance æpp will be launched.
  4. IMPORTANT: All AE tokens users must migrate their AE tokens to the Mainnet before September 2 when the smart contract that manages all Ethereum AE tokens will expire.
  5. Auctions for renting names in the æternity Naming System (AENS) will be launched with Lima.
  6. A mobile æpp that enables state channel payments will be available during the æternity Universe One conference that will take place in Prague, Bohemia on September 20–21, 2019.

Here is the draft timeline for the Lima Release, token migration and the September hardfork.

The roadmap is divided in the following three (3) Sprints.

SPRINT 1 (2 Weeks)

  1. Solve the issue where merchant payment notifications may get lost
  2. Implement support for reconnection so the user does not need to keep the application open at channel creation stage. This applies also to onchain TXs where the user must wait a number of confirmations such as withdraw, deposit, and channel close (*)
  3. Restore Withdraw/Deposit functionality. This was broken some time ago (**).

SPRINT 2 (2 Weeks)

  1. Finish clearance mechanism to distribute funds to seller
  2. Properly handle all “user cancel transaction” scenarios (*)

SPRINT 3 (2 Weeks)

  1. Write final documentation.
  2. Solve all current UI issues, especially getting proper display on all common form factors

(*) Features depends on aeternity node-sdk features availability

(**) Channel die immediately after deposit

DESIRABLE FEATURES

  1. Unify Merchant/Customer roles in one application.
  2. v1.0 UI Should offer information such as current version, license information, minimal help and settings screen.
