Æternity: The Lima hardfork Was Performed Successfully, Payment Application Update (0.9.20), A New Version Of The Elixir SDK, Microsoft-backed MIC Partners With Æternity To Promote Blockchain In Malta

Biweekly update 22nd October - 5th November

æternists are welcome! The development teams, foundation, and grantees keep making us proud of their work. They continued moving forward on the roadmap, and finally, the Lima hardfork was performed successfully at block height 161150. Thus, the aeternity Mainnet is currently running Lima Release 5.0.1. The upgrade adds a sophisticated, improved virtual machine (VM), governance, and naming system to challenge Ethereum and other blockchain platforms. As for other development updates: the aeternity blockchain Naming System or AENS gone live and the video tutorial where Emin Mahrt showed how to register a name was published; AirGap worked on implementing security fixes discovered in the security review and making the library more secure by protecting it against insecure dependencies; SDK JS and Python 6.0.1 for æternity is now out; Æternity payment application was updated, featuring restored deposit after channel-creation functionality and support of a cancellation of base-aepp SIGN dialog at Channel Open request.

Furthermore, a brief recap of æknow progress and few updates of grantees were published. Karol Skocik worked on the first implementation of AENS.update function support in Sophia contracts for ænode. Juraj Hlista released a paper about a new approach for signaling outcome computation — the initial assumption that the miner indicating parameters could be modified during node restarts and decided it’d safer not to be able to modify them instead was changed; the second approach uses a database table to store aggregated signal count per a key block.

As for the social life of æternity: several videos, interviews, and articles were published, meetups and workshops were sponsored and arranged. Don’t miss Michal Zajda explaining in his recent article how the fusion between æternity and the Bitcoin-NG protocol delivers a UX and technical leap in the everyday blockchain. Besides, did you hear that aeternity is among the nominees at the MCannabizWorld awards? The æproject is in the race for “Blockchain of the Year”!

By the way, æternity had previously announced a partnership with Uruguay’s Digital Party to build a new system to optimize the country’s democratic process and internal voting in a transparent and decentralized manner. As part of this partnership, a DApp based on the “liquid democracy” model will be created and would employ digital tokens and smart contracts for the internal governance of the Digital Party. Now, Microsoft-backed MIC partners with Aeternity to promote blockchain in Malta. Mass adoption is near! Importantly, the æcommunity is super-supportive, and the number of subscribers in social networks has a slight increase. Stay with us, and we will keep you informed!

  • The Lima hardfork was performed successfully at block height 161150. The aeternity Mainnet is now running Lima Release 5.0.1.
  • Check out the work of Juraj Hlista, one of the foundations grant recipients. Technical Paper on Miner Signalled Consensus Upgrade is available here. 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.

  • Check out the latest update coming from the AirGap /Paper:

AirGap Vault

Implementing security fixes discovered in the security review

  1. Update to latest Ionic 4 version and Angular 8 with improved performance
  2. A lot of internal changes/bugfixes in preparation of the upcoming release

AirGap Coin Library

  1. Working on making the library more secure by protecting it against insecure dependencies

Other

  1. AEX Call and feedback for the metadata AEX
  2. Post Lima Token Migration call / discussion with other devs

CHANGE LOG — 0.9.20 (191025)

  1. Updated Aeternity SDK to 6.0.0
  2. Restored Deposit after channel-creation functionality. This should already work with nodes >= 5.0.0-rc5.
  3. Supports cancellation of base-aepp SIGN dialog at Channel Open request.
  4. Fixed an issue where merchant payment notifications may get lost
  5. Close channel/Deposit/Withdraw screens won’t let display to sleep to prevent connection gone broke.

KNOWN ISSUES

  1. Scrolling issues with Android. Please switch to floating keyboard if needed.
  2. When OnDemand mode is active, Withdraw is not available.
  3. Canceling transactions through Base-Aepp dialog may cause channel to enter inconsistent state.
  4. Do not switch subaccounts except before channel opening.
  5. Page Refresh/Exit may cause problems if a channel operation is underway. This should be fixed with future 5.1.0 node Release. This is currently mitigated by keeping display and CPU active while on-chain tx is in course.

Progress:

  1. Released a new version of the Elixir SDK with full compatibility to aeternity node v5.0.0-rc.5.
  2. Secured Keystore implementation, supporting various cryptographic functionality, as well as improvement and bug-fixing on private key related activities.
  3. Added additional layer on private key, in order to hide it when BEAM VM is crashed, so the key won’t be seen in crash logs.
  4. (WIP) Middleware — added support for API calls.
  5. (WIP) Spend-by-name — possibility to make spend transaction by providing only a name of a recipient.

This is what happened in September, for earlier updates tap the link above.

Further improvements to NS happened during September in two areas.

  1. The first is implementation of AENS.update function support in Sophia contracts for AE node: PR 2781
  2. This work requires support in bytecode and Sophia compiler changes as well.
  3. Summarized report with more detail can be found here.
  4. The second change is allowing the name hash to be used for querying of oracle: PR 2797
  5. Summarized report describing this improvement is here

September

The refactoring work continued, which resulted into several pull requests ( PR #2760, PR #2763, PR #2769, PR #2774, PR #2778, PR #2793, PR #2800, PR #2802, PR #2804, PR #2837, PR #2847).

Moreover, a new approach for signaling outcome computation was suggested — they changed the initial assumption that the miner signaling parameters could be modified during node restarts and decided it’d safer not to be able to modify them instead. The second approach uses a database table to store aggregated signal count per a key block (PR #2868).

End of September — mid-October

With the addition of the miner signaled consensus upgrade, the configuration of the node was changed as well. Also there were unit and system tests implemented. All of this was part of the PR #2868. Moreover, there were two minor issues found and fixed (PR #2910 1, PR #2913).

Social encounters

  • Check an article about how aeternity blockchain developers take on Ethereum with final hardfork. As the third and final major æternity protocol upgrade this year, LIMA adds a sophisticated, improved virtual machine (VM), governance, and naming system to challenge Ethereum and other blockchain platforms. This upgrade delivers improvements to state channels, in which the aeternity network relies on to power scalability. Built into æternity’s first layer, opening a lightweight state channel is a simple transaction, with computation completed by a trusted node. Once set up, state channel users do not need to pay fees or spend gas to execute smart contracts and transactions. All communications are private until published on-chain in the case of a dispute or after the closing of the channel. In addition, LIMA introduces æternity’s next level of decentralized governance and the completion of its full migration from Ethereum to the æternity blockchain. Initially created as an ERC-20 token on Ethereum, the AE token has now fully migrated to the æternity mainnet. This was made possible in part by generalized accounts, which make æternity highly flexible and let developers create smart contracts that can verify transactions.
