Testnet - Eager Electron 5.1.9763

TL;DR Release Highlights:

• Offline transactions add the option to use offline addresses: no need to wait for the receiver to come online anymore!
• Atomic swap fees have significantly reduced
• Dozens of under-the-hood bug fixes you don’t want to know about, as Beam “just works”

Features:

• Enabled Offline transactions by implementing Lelantus MW protocol
• For Offline transactions new “offline” addresses are supported: it includes all the necessary information for 10 payments so that a receiver doesn’t need to talk to the sender to create a transaction. Once the ten payments run out, the sender wallet will automatically request more payments from the receiver using SBBS. In case the Receiver is not online and not responding, the Sender wallet will show an indication that there are no more payments left and the user will request a new address using external channel.
• Atomic swaps are significantly cheaper now due to SegWit support and a minimal fee rate is nicely recommended so that transactions will complete within a reasonable time
• Confirmation count is implemented for CLI wallet and in API to better align with exchanges

Improvements:

• Confidential Assets metadata is standardized. Read more here.

Fixes:

• CLI wallet: for AS with Electrum node - user can add any number of receiving and change addresses

Known limitations:

• When using active laser beam channels the CLI wallet should not be offline for over 24 hours

Points to mention:

• Offline transaction fees are higher than Mimblewimble transactions and start from 0.01 BEAM per UTXO. The receiver pays his fee (per coin) when the coin is withdrawn from the shielded pool.

Eager Electron 5.0.9146.2863

IMPORTANT: Before upgrading to 5.0 all Atomic Swaps need to be concluded or canceled and all open Laser Beam channels need to be closed!

This 5.0 (Eager Electron) release paves the way for Beam towards a confidential finance ecosystem, enabling multiple features in CLI that will be introduced later in UI wallets such as confidential assets, breaking linkability and many others.

After Beam blockchain will reach the block 777777 the upgrade to 5.0 is mandatory to access your funds.
Important information for Exchanges and Mining Pools: Confidential Assets-related functionality (e.g. send/receive etc.) is disabled by default. To enable explicitly, use --enable_assets command-line option when running BEAM API or BEAM wallet CLI. Please read the complete tutorial here.

Features:

• [miner, node] BeamHash III - the new, the great and the last POW algorithm for Beam
• [cli] Break transactions linkability with Lelantus MW (for Beam and any CA)
• [cli] Non-interactive transactions
• [cli, api] Issue, burn and transfer confidential assets (disabled by default)

Improvements:

• [node] added an option to manually specify preferred peers for rare edge cases
• [api] The number of confirmations is now available to the transaction sender and receiver
• [desktop wallet] introduced new and more informative “failing” status for Atomic Swaps when the transaction is rolling back
• [desktop wallet] The default offer expiration for Atomic Swaps was extended from 30 minutes to 12h

Fixes:

• [desktop wallet] Wallet update notification will not be displayed if a wallet was… (surprise) already updated.
• [api] swap_offer_list command provides the list of offers as expected.

Other:

• [desktop wallet] Infrastructure change: the UI code was extracted to a separate repository to speed-up the development and QA process in the future

Known limitations:

• When using active laser beam channels the wallet should not be offline for over 24 hours
• Atomic Swaps of Confidential Assets with BEAM/BTC/LTC/QTUM will be released later on

Points to mention:

• In case a mobile wallet is connected to a random node and the user has both mobile and desktop wallets that are using the same seed phrase, the funds sent to the desktop wallet won’t appear on the mobile wallet. If the desktop wallet is running a local node, it will see funds sent to both wallets. The reason is that the local node (integrated into the desktop wallet) always monitors the blockchain for UTXOs related to the seed of the wallet. The mobile wallet does not run a local node and thus can only monitor transactions sent to its specific SBBS addresses. Of course, no funds will be lost in any event.
• BEAM wallets won’t display received Confidential Assets and amounts kept in the shielded pool. Please use CLI ar API till the future notice.

No worries, our wallet will never auto-update - this decision is entirely in your hands.
• [desktop wallet] Exchange rates to USD/BTC. Under the hood we use the same decentralized notifications infrastructure, hence again, your privacy stays solid.
• [api] Atomic Swap API for market-makers. Build your systems to manage decentralized atomic swap orders!
• [infrastructure] Wallet Identity was added to proof and ensure that transaction performs between claimed participants.
• [cli wallet] Laser beams for instantaneous BEAM transfer
