Technical Update 20
Fantom has continued to develop additional functionality and security to the network; for example, by extending our work to make Lachesis ABCI-compatible. This will allow Lachesis to have Tendermint-like functionality with the ability to plug into different services, thereby offering Lachesis as Consensus-as-a-service.

Go-Lachesis

Upgraded nodes in public testnet to v0.6.0-rc.2.

Expanded app.blockContext to call App.DeliverTxs() on each transaction separately: https://github.com/Fantom-foundation/go-lachesis/pull/456

Removed the dependency of evmcore.NewStateProcessor() on stateReader from gossip: https://github.com/Fantom-foundation/go-lachesis/pull/470

Completed the first stage of performance tweaking in preparation of launching a test environment to measure performance. The test environment will consist of the following modifications:

R1: Users can submit transactions into any node’s transaction pool.

R2: A node can pick txns from its own pool and generate new event block.

R3: A node can send its own event block to any peer node of the network.

R4: Removed the restrictions of event emission rate.

R7: Disabled the fork mechanics.

R9: Removed free gas parents (we won’t need gas and fees in a testing environment, as we are measuring tx performance).

All changes are merged to develop — https://github.com/Fantom-foundation/lachesis-ex/tree/develop.

Implemented logic to check the node for latest Lachesis version: https://github.com/Fantom-foundation/go-lachesis/pull/471

Improved test coverage to 82.5% for go-lachesis/ethapi package: https://github.com/Fantom-foundation/go-lachesis/pull/455

Created new Private txpool:

Added new functionality to the existing evmcore. TxPool is a sheet, which has marks that this transaction is private. We need to not send marked transactions to gossip.ProtocolManager

Duplicated all methods of sending transactions by methods with the addition of this mark (ethapi and the console)

Make sure that emitter receives private transactions without timeout

https://github.com/Fantom-foundation/go-lachesis/pull/472

Upgraded the public testnet (with 3 nodes) to v0.6.0-rc2 from v0.6.0-rc1, and upgraded the SFC as well

New Fantom Wallet

Our new official Fantom Wallet, which we’re building as a Progressive Web Application (PWA), is nearing completion. It will have built-in Ledger support. The application with be downloadable as a desktop or mobile wallet, and will also be available as a web wallet.

The repositories related to the PWA wallet are:

Removed dependency on Web3js provider and default connection to Val1 full node, which should remove a bottleneck causing wallets to lag in times of high load: https://github.com/Fantom-foundation/fantom-metamask/commit/bc990d1ae9b143f710ec0c351f9b43ec09372e9

Created new UI connected to Metamask and GraphQL, with commits such as the following:

Modified GraphQL API to be compatible with new PWA wallet:

Completed Ledger App development. Currently in the process of connecting it to the PWA wallet.
