Prysmatic Labs Have Released Ethereum 2.0 Prysm Demo v0.0.0

Prysmatic Labs Have Released Ethereum 2.0 Prysm Demo v0.0.0

In his today’s article on Medium, Raul Jordan, blockchain developer and Prysmatic Labs editor, announces the release of Prysm, v0.0.0, which will serve as the building block for all future releases as they get to production

Inside the Release

Version 0.0.0 includes a basic beacon-chain+validator demo which can do the following:

  • Spin up a beacon chain node from a genesis configuration
  • Connect a validator client to the beacon node via RPC
  • The validator client gets shuffled into a specific shardID at a given slotevery cycle transition
  • Validators propose/attest to canonical beacon blocks during their assigned slot

How to Run the Demo

Here is the instruction on running Ethereum 2.0 Prysm Demo v0.0.0.

You’ll be able to spin up a beacon node, connect 1 or more validator clients, and start getting assigned to shards where you will then create beacon blocks or vote on beacon blocks through structures called 'attestations'.

This beacon chain node+validator client system is a critical piece of consensus and coordination for all actors participating in Ethereum 2.0 and will serve as the foundation for a full-fledged, sharding system.

What's Up Next?

There is a lot to be done with respect to the randomness generation and signature aggregation on the beacon chain as well as validator rotation. This is all phase 0–1 of the Ethereum 2.0 roadmap, as sharding state execution will not come until phase 1 and 2.

Amrit Kumar on Smart Contract Security, Blockchain Sentiment, and the Future of Zilliqa

Amrit Kumar, Zilliqa President and Chief Scientific Officer Amrit Kumar Decentralized app (dApp) platforms seem to be running into issue after issue lately. Many have trouble scaling while others have seen some nasty bugs due to smart contract vulnerabilities. The Zilliqa team is aiming to turn that around. Zilliqa implements sharding, alongside its own programming language, Scilla, to bring forward a more secure, scalable blockchain. This week, CoinCentral’s Steven Buchko had the pleasure of speaking with Amrit Kumar, the President and Chief Scientific Officer of Zilliqa. They discussed blockchain privacy, advice for the industry, and the issues in the smart contract landscape today, among other topics. Read on below: In a ​recent interview​, you mentioned that you started out as a postdoc researching privacy-enhancing technologies for blockchains. What are your thoughts on the current landscape for those technologies and the privacy coins implementing them? Privacy-preserving and privacy-friendly technologies have definitely made their way into blockchains.  Several projects such as Monero, ZCash, and MimbleWimble are good examples which have implemented privacy technologies in different forms. They can help anonymize the sender of a transaction, hide the amount transacted among, etc.  In parallel, we are also witnessing a lot of tooling being developed specifically around zkSNARKs – a privacy-preserving technology to prove the knowledge of certain secret data. With zkSNARKs and similar cryptographic primitives, the reach of privacy is being pushed beyond simple payments to running smart contract transactions. It is interesting to see that many of these privacy technologies can actually be used for other purposes such as scaling.  zkSNARKs are being adopted by several projects to be used for scaling and not necessarily for privacy. This clearly shows that many of the underlying primitives in privacy coins have much broader applications than just privacy. Regarding smart contract development, what issues do you see in traditional programming languages like Javascript, and why do you feel that even Ethereum’s Solidity still falls short? It’s important to recognize that ten years on, the blockchain industry is still largely in the process of determining and establishing the best practices – be it the best infrastructure to use for a particular use case, or in this case, the best programming language to design smart contracts. That being said, in this nascent stage, the current infrastructures we have at our disposal are but a work-in-progress. Legacy programming languages, especially Javascript, have the benefit of being regarded as the “gateway” language for newcomers looking to acquire skills in coding. Widely known and applicable to different areas of computer science, Javascript significantly lowers the barriers to entry for an area of the field that’s regarded as highly complex. With its emphasis on usability, the use of Javascript as a native programming language on any platform will be highly beneficial as a project looks to build up their community as they onboard new developers.  Similarly, a language like Ethereum’s Solidity was equally designed with usability in mind, making it the most popular programming language for smart contract design.  However, history has shown that the language itself was not designed with safety in mind. With incidents such as the DAO and Parity hacks, where wrongfully-inputted code resulted in the loss of significant amounts of money, we can see that greater security is needed at the language level.  With mainstream adoption as the long-term goal of every project in the space, a greater emphasis needs to be made on developing secure-by-design infrastructures. In order to enable far-reaching solutions enabled by smart contracts, be it in the financial services sector or healthcare, where significant volumes of currency or sensitive data are transacted, security ​must​ come first. At Zilliqa, we’ve tried to address this problem by developing our own smart contract language, Scilla, which was designed with functional programming language principles in mind. In so doing, developers will be able to leverage mathematical proofs in order to ensure that their contracts are provably correct.  This is only one approach, and I’m certain that there will be many others, as more projects look to develop far more security-oriented solutions. While we cannot downplay the value of languages such as Javascript and Solidity, and how they’ve largely shaped the trajectory of smart contract development, it’s clear that our path as an industry doesn’t end there.  As we look to establish best practices going forward, language designers will be able to glean from past experiences and develop even something better – a language that provides better security while allowing for expressivity and tractability. Sharding is at the crux of Zilliqa’s design. We know that higher throughput is a significant value-add, but what are some of the potential downsides? Zilliqa implements sharding to improve scaling. | Source: Zilliqa If you compare a sharded architecture with a non-sharded architecture (such as Ethereum in its current form), there is a drop in decentralization for sure, as in a sharded network only a subset of nodes from the entire network processes a given transaction. However, if the size of that subset of nodes is sufficiently large, then the level of decentralization should be acceptable. Zilliqa, for instance, requires that number to be 600 nodes. You released the Zilliqa mainnet this year. Which dApps excite you the most? Unstoppable domains is a project running on the Zilliqa mainnet which I am really excited about, particularly from the user experience perspective. They are building a naming registration service to replace long hexadecimal account addresses with simple human-readable names. This project is important to make it easier for the non-blockchain crowd to own blockchain-backed assets and transfer them around. Unstoppable Domains create human-readable Zilliqa wallet addresses. | Source: Unstoppable Domains Other than Zilliqa, which blockchain projects interest you the most? Within a rapidly developing space, it’s been exciting to witness the ongoing research and development across the industry. In the past few years, there’s been a lot of exciting developments being made in the respective Bitcoin and Ethereum ecosystems when it comes to areas such as governance, scalability, and consensus algorithms. More specifically, however, I’ve also been interested in some of the more recently-launched projects that are shifting towards more privacy-oriented offerings as well as layer-2 (off-chain) solutions. On ​Twitter​, you’ve emphasized the importance of critical feedback. What pieces of critical feedback do you have for the blockchain industry? As a researcher and an academic at heart, I find that critical, albeit constructive, feedback is necessary to facilitate growth. Ongoing, consistent improvement should be the goal.  That being said, having entered this fast-paced industry where entrepreneurship, innovation, and technical excellence are so valued, it’s easy to forget that we’ve only just started. I personally would like to thank you for your feedback. I really appreciate it, I indeed do. Having said that, I do disagree on a couple of points. Personally speaking, as a researcher, all I care about is critical feedback. I already know what I am good at. — Amrit Kumar (@maqstik) June 23, 2019 While it’s difficult to separate the speculation of cryptocurrency prices from the meaningful technological developments being made in the space, people do need to remember that there’s more to cryptocurrencies than price and that there’s more to blockchain than just the value of a project’s token.  Within an inherently volatile space, where cryptocurrencies are still treated as a speculative asset, it can be frustrating to many that a lot of the work being done behind the scenes isn’t always translated to the price movements of a token, and I understand that. However, it also bears consideration that there are larger macroeconomic factors at play, be it regulatory developments or even regulatory sentiments as a whole.  The entrance of traditional players in the space can equally shift prices, as we saw with Facebook’s launch of Calibra and the launch of the Libra Association. Ultimately, it all boils down to sentiment.  Beyond this, it’s important to remember that disruption is a two-way street. We might be changing the way things are done in certain industries, but by partnering with traditional leaders in these verticals, they add the legitimacy and contribute to the wider attitudinal shifts taking place on a grand scale. In partnering with legacy companies or publicly listed organizations, this means taking a more measured approach to how announcements are shared and news is disseminated throughout the space. What’s next for Zilliqa? Last month, we announced our first foray into the payments space by way of our partnership with Xfers, a FinTech payments solution provider. As one of the leading payments platforms for online businesses and end-users in Singapore and Indonesia, as well as the first non-government company in Singapore to become accredited by the Monetary Authority of Singapore as a Widely Accepted Stored Value Facility (WA SVF), we’re excited to be supporting them as they explore the potential of distributed ledger technology in this next phase of transaction growth. Beyond this, we have some exciting announcements in the pipeline for this month, so watch this space!  On the tech front, we have a tech-heavy roadmap for the next 8-12 months working on improving the infrastructure that we have already built by adding new features to it. We will also be working very extensively on toolchains and making dapp development on Zilliqa as easy as possible. Thank you, Amrit, for your time and insight!

If You Missed The Bitcoin Bus, You Could Still Catch Up With These 3 Altcoins

Bitcoin has been at the center of everyone’s attention since the inception of the cryptosphere. Though it is to be expected due to the novel nature of distributed ledger systems and blockchain technology, one has to be able to see what next is coming so as to catch the next crypto wave. The key to making a killing in any market is to be in the marketplace before anyone else! And that’s why altcoins are important! After Bitcoin, other cryptocurrencies are going to take center stage; some even more than Bitcoin in the future. So, while you may have missed the Bitcoin bus, here are others which you can catch. Ethereum (ETH) A whole lot has been said about the end of Ethereum as a cryptocurrency, Up to the point that most people hailed the EOS blockchain as “the Ethereum killer”. It didn’t turn out to be the case! However, most people don’t get the point, Ethereum isn’t only a cryptocurrency, It’s a family of currencies. And that’s where it beats Bitcoin in terms of functionality. The use of Smart Contract compatible tokens creates a new paradigm where new tokens are launched on the Ethereum main blockchain. This, of course, creates problems of scalability which new technologies such as Raiden, Plasma and Sharding are all expected to come on stream in the next few months. Expect great surprises from Ethereum! Ripple (XRP) Ripple hasn’t been without its controversies. The arguments for and against a cross border real-time settlement system have been many. However, with the current financial system having a significant overload, it’s time for everyone to consider the fact that maybe Ripple can indeed live up to the hype. After all, its CEO is actually investing in major centralized technologies and large financial institutions just to prove a point! Binance Coin (BNB) Many people may not recognize the significant impacts of the Binance exchange in the digital asset industry. Binance has actually been the market leader when it comes to cryptocurrency exchanges for quite some time. This is because the management team of the exchange understands how cryptocurrencies function and what the industry needs to help it progress further. Its BNB token has attained great strides that keeps taking it to new heights. So, there you have it. In answer to the issue at hand, yes it’s time for altcoins! If you get in early, you might just catch the next wave which is going to be way bigger than the last one! What do you think? Is it time for altcoins or is Bitcoin going to be the only Big guy in the cryptosphere? Please let us know in the comments below!
