Ethereum, Libra and a Unified Type System

Conclusion
Ethereum is a global operating system. So is Libra, even if the computing power is currently capped at 100 validators. The advantage that a global operating system brings to a type system is type reuse and interoperability between projects.

Developers can collaborate on types and upgrade them as time passes. Projects can have compatible APIs and your project is part of a bigger system.

Libra has already started to put types/resources as first-class. At the moment, developers are not allowed to publish their own types and there is no estimation of when they will be able to do so. Libra core developers will probably release their own types first, before they open the system to outside developers, to ease use. And there is a chance that they will end up controlling what types are predominantly used (if not entirely) on their network. This means they would be intermediaries and external projects will collaborate with them instead of with each other.

Ethereum can still make the first move if it starts adopting a type system. It might influence the Libra type definitions or at least it will be prepared to include them into its type system, to ensure compatibility.

Dear Ethereum people, if we do not want to lead today, we will be forced to follow tomorrow.

Facebook’s proposed currency is technically sound, but should you trust it?
You can probably trust Libra’s technical design, but whether you can trust Facebook is still unclear.

Members of The Libra Association invested in the creation of a custodial repository Anchorage

Blockchain Capital, Visa and the Andreessen Horowitz venture Fund, which are part of The Libra Association, have completed the second round (https://medium.com/anchorage/series-b-c15eba09e344) of investments in the anchorage FINTECH startup. Anchorage is a custodial service for storing crypto assets and other financial instruments with two-factor identification "without passwords". Anchorage is also a member of the Libra Association.

Authentication and authorization will be carried out using biometric data or an electronic signature certified at the state level in different countries.

A large custodial service for cryptocurrency storage will solve the issues of accounting, tax preparation and audit, which are the main problems for institutional investors (pension funds, insurance organizations, credit unions, etc.) who want to add digital assets to their portfolios.

Will Facebook and Telegram Kill Bitcoin and Ethereum? I liked this thought "Libra will be the currency of choice for e-commerce and money remittance for the underbanked. Most likely, we will see challenger banks entering the space to provide credit and accepting deposits in Libra. Still, the centralized nature of Libra and an open question regarding the support of smart contracts leaves plenty of room for TON."

TON does not even have WP available =))

And some bank in Thailand is already interested in supporting Libra

I write that it is not for everyone, it must be looked for in some groups, somewhere on the Internet.
In Libra, everything is in sight, you want to look at WP, go to the site or keep the link and see. Do not hide anything and a lot of things painted

In TON, something written there from the bald, just to be =))

In the event of a final decision on joining Libra, Monex will be the first company from Japan to be involved in the project of the world's largest social network. To become a full member of Libra, the company will have to pay an entrance fee of $ 10 million.

An application submitted by Monex to join the Association will undergo an initial review in August, and in September Monex will make a final decision on the appropriateness of such a decision.

Since the official Libra project announcement in June, response from the developer community has been thrilling to watch. Developers have released several blockchain explorers (libranaut, libraview, librabrowser, and libexplorer) and integrated Libra testnet into their wallets (ZenGo, including a large PR to Libra Core). We've also seen other blockchain projects integrate Move into their systems (Solana). Calibra continues to develop Libra Core heavily on GitHub. The team has also released two new guides: one for running Move applications locally and another showing how to run your own network. The Libra Discourse forums are active with discussions about transaction scripts, client development, and interest in Libra events continues to grow.

Steady technical progress and open and transparent dialogue are key to growing developer interest in the project. As Libra Core progresses towards Mainnet, look for blog posts like this one to find roadmap updates.




Beyond Testnet
Launching the Testnet has allowed the team to quickly improve Libra Core by making it easy to troubleshoot, diagnose, and resolve software edge cases. The Testnet demonstrates Libra network functionality and provides early access to developers.

Following the Testnet, we hope to have a successful launch of the Libra Mainnet. One method we use for tracking the project's success is how many of the deployed nodes are managed by different partners. The end goal of Mainnet is for all partners to have nodes deployed on the network. Each node will run on a mixture of on-premises and cloud hosted infrastructure. Our belief is that wider diversity of infrastructure will provide more resiliency to the Libra network.

GitHub Updates
To help you better track development progress we've added a Kanban board (visualized task board) containing all major engineering priorities. You can track this Roadmap's progress here.

Like many open source projects, contributions must have be made pursuant to a signed contributor license agreement (CLA). We are reviewing a handful of options to streamline the existing, manual CLA approval process.

The current development process enforces a high level of code quality. One tool we've adopted is homu. Homu is an open sourced bot that works with our continuous-integration/continuous-deployment(CI/CD) systems to ensure tests always pass. Our homu bot, @bors-libra, works by continuously verifying that tests pass between PR revisions and after other PRs are merged. You can see commands issued on PRs that tag the bot and instruct it to do work. Using a bot for managing merges, is common in larger scale projects that want to keep tests "green". This change adds an additional layer of security to the project by enforcing branch protection so that changes to the protected branch can only be executed by the bot.

The engineering team has started to post their design notes in GitHub issues. If you're looking for ways to get involved, or want to track specific features, and give feedback you can scan the GitHub issues page.

We are working towards providing clearer and more plentiful ways to help you get involved over time. We hope that publishing this and future roadmaps, updating the status of high level priorities, and sharing design notes can give you guidance and insight into upcoming Libra Core features.

Sprint Based Development
Since the beginning of the project, the team has used 60-day sprints to help guide planning and development of Libra Core. Each sprint has a set of features organized by priority. For Roadmap #1 the team is focused on security and reliability and work towards integrating additional partners into the coming Libra Mainnet.

Goals for Libra Core in Roadmap #1 are to focus on security and reliability and to integrate our first partners into the Libra network pre-Mainnet.

Roadmap #1
Current Progress
We continue to complete design work for all priority features. We are making good progress implementing features like Full Nodes. We're working to define node reconfiguration specification will work prior to finalizing the Libra Protocol definition.

Libra Core
Addressing / Interop

  • Interoperability between multiple wallets is key to the success of the Libra network. The team is working to formalize a simple scheme to support sending to/from sub-accounts.
Full Nodes

  • The Libra blockchain will consist of a single node type that can be configured differently. This will allow the node to act as either a validator or a non-validating node that stores full history (full node). We will also work to allow easily upgrading full nodes to validators and vice-versa.
Libra Protocol Definition

  • The team is working to define the API, Wire Spec, Addressing/Interop, and other protocol dependencies.
Validator Reconfiguration

  • The validator set contains unique identification of validators active in the system. Over time, the validator set needs to support changes. From a blockchain systems perspective, changing the validator set impacts every component. Consensus needs to re-certify blocks, the network needs to to reconfigure, storage needs to persist a LedgerInfo, and clients need a way to validate read data across validator changes.
Waypoints

  • Waypoints will provide clients with an external source of information about the history of the blockchain.
TCB (Trusted Computing Base)

  • The trusted computing base (TCB) defines subsets of components that are critical to system safety and stability. Minimizing the hardware and software dependencies of the critical components helps avoid inadvertent bugs and malicious attacks.
Serialization

  • The team is looking to implement deterministic serialization for sharing RawTransactions between validator nodes. To see more discussion on this topic, see issue #454.
Move
  • Events
    • Explored designs for representing events in Move.
    • Stabilized Events API for developers.
    • Provided examples for how developers could record events that happen on-chain.
  • Collections/Generics
    • Implemented vectors and explored other collection types to support.
  • We landed #597 which unblocks validator set management. There is additional work to support this in the verifier and as part of the correctness assurances.
Libra Pre-Mainnet
As the project tracks towards the Mainnet milestone, it is necessary to bring more nodes online while maintaining the operation of the testnet. To aid this effort, we've created a staging environment that we call Pre-Mainnet. Pre-Mainnet is currently only accessible to partner nodes to allow them to connect to each other. A handful of partners have already deployed their nodes and have them communicating with each other. We expect to have more partners coming online shortly. We want to ensure the Libra network can meet rigorous performance benchmarks and overall system stability before opening access. Stay tuned.
