Discussing Quorum Blockchain Basics

Discussing Quorum Blockchain Basics

Quorum blockchain is in limelight for past some time and this is how I was prompted to learn quorum blockchain basics and read about quorum blockchain guides on the internet. I am trying to share my quorum blockchain learning experiences here.

This article may be considered as a part of quorum blockchain tutorial but it is not a quorum blockchain ultimate guide.

Recently, there were news that…

How to Become a Blockchain Developer: A Step-by-Step Guide

The blockchain is now reading Technologies that are revolutionising the existing world environment. According to estimates, the worldwide blockchain market will be worth $20 million by 2025. Blockchain technology uses a distributed database that is shared among computer network nodes. Blockchain

Data is stored electronically in a digital format. It's vital in cryptocurrency systems since it keeps track of all agreements and transactions in a safe and decentralised manner.

Developer of blockchain technology

A blockchain developer is familiar with all of the terms used in the Bitcoin and Ethereum protocols and will use them to build a real-world application in this ever-changing environment. There are two categories of blockchain developers, just as there are in other fields:

Blockchain developer at the core

The blockchain protocols consensus protocols were sketched out by the core blockchain developers. He helps with the implementation of various blockchain technologies and functionalities.

Developer of blockchain software

Developers of blockchain software make it easier to create APIs for blockchain integration. In decentralised applications, he also serves as a frontend and backend developer.

How do you go about becoming a blockchain developer?

Technical abilities are essential.

To become a blockchain developer, you'll need a set of technical talents, which are listed below:

Skills in programming

A solid understanding of different high-level programming languages such as Java, C++, Ruby, Python, and others is essential. The proper grasp of OOPs is critical for designing applications and doing other jobs.

Understanding the fundamentals of cryptonomics

A Blockchain developer should be familiar with the economics and methodology that underpin cryptocurrencies and their networks. It is necessary to understand basic fundamental concepts such as the Bitcoin transaction lifecycle, transaction fees, and other essentials.

Structures of data

It is critical to comprehend data structure principles like as trees, heaps, hashing, and so on. Blockchain developers may create immutable and efficient systems by understanding data structures.

Solidity and smart contract development

Smart contracts make it easier to employ protocols for automation where no third parties are involved. It addresses the following three critical elements:

1. Predictable

2. Cancelable

3. Separation

Solidity is a high-level language based on JavaScript that is used to type or build intelligent contracts.

Databases and networking are both important.

An understanding of databases and networking concepts is also essential, in addition to all of the skills listed above. Database and networking principles aid comprehension of distributed system mechanisms and other important topics.

The steps to becoming a blockchain developer are outlined here.

STEP 1: Educate yourself on the fundamentals

Begin by understanding some fundamental concepts such as ideas and architecture. Understand the relevance of consensus in many decision-making domains, as well as the concept of decentralisation. Understanding cryptocurrencies and familiarising yourself with the various cryptographic algorithms used by blockchain solutions is critical. Examine blockchain ecosystems, including Quorum, Corda, and Ethereum Enterprise, as well as enterprise Blockchain platform and Blockchain as a Service (Baas).

Step 2: Gain an understanding of how blockchains work.

After you've mastered the fundamentals, you'll need to tackle some real-world applications. You can begin working on cryptocurrencies, purchasing them, creating offline wallets, and completing other procedures. Following that, you'll have an understanding of the numerous terminologies associated with cryptocurrency. It would be beneficial if you were certain that you were aware of all of the safety segments.

Step 3: Take a blockchain tutorial and learn how to code.

Online blockchain tutorials are a good place to start. You must also build practical knowledge, which will be developed through coding, in addition to academic understanding. Begin by learning Solidity, which will aid in the development of dApps and smart contracts on the Blockchain. You can also examine the open-source code of several blockchains, but doing so needs some expertise in order to solve security, performance, resource management, and isolation issues.

STEP 4: Become familiar with smart contracts.

Smart contracts are the most important Blockchain concept. It's a form of computer protocol that's analogous to a real-life legal contract. After learning about smart contracts, you can quickly automate and integrate API functionality.

Step 5: Go over all of the blockchain-related material.

Make it a practise to read blockchain-related material from a variety of publications and websites. The content is available on a variety of websites, including 101Blockchains.com and BlockGeeks.

STEP SIX - CONTINUE TO IMPROVE

There are no boundaries to what you can learn. After you've grasped the fundamentals of Blockchain, you'll need to move on to higher-level ideas. To master this field, simply dig out the deepest surface. Maintain your knowledge and self-assurance. You can get recent upset updates by subscribing to the education system block.

The following are the top ten companies that are looking for blockchain developers:

1. Deloitte

2. IBM

3. KPMG

4. EY

5. Accenture

6. Cisco

7. JP Morgan Chase

8. Microsoft

9. Conduent

10. ConsenSys

Conclusion:

This was all about the how-to guide we created for becoming a blockchain engineer. If you want to work in the blockchain industry, now is the greatest moment to start. The tips we offered will assist you in becoming a better blockchain developer and in selecting the ideal course for your needs.

Annotated edition of May 10 Week in Ethereum News

I’ve started thinking of the annotated version as aimed at Eth holders.  There’s a large group of people who hold ETH who want to stay up to date on what is happening, but also have jobs outside of the industry and may not understand all the tech nuances nor have time to spend.  So the annotated edition will try to give you more narrative, more context, some opinion, maybe some 🌶️, as well as pointers to what might you want to read

Fun fact: you can find the #MostClicked and #MuchClicked on Twitter by just searching the hashtags. The usual caveats apply: the things most clicked are the things people hadn’t otherwise seen (not necessarily the most important), and my tweets auto-delete after a month or two, so the data only goes back a couple months.

Before clicking send, I knew for sure which would be the most clicked item this week.  I was right.

How did I know it would be the most clicked?  Because even among Ethereum enthusiasts it’s an undercommunicated thing how low eth issuance will be.  It is planned to sustainably be so low that it might at some points go negative (and perhaps be negative over long periods of time, which worries me a little!).  Perhaps part of the reason we don’t communicate this that loudly is because we just aren’t there yet.   But unlike Bitcoin which has no path to long-term sustainability, Eth has a logical plan to have very low issuance.  

As I said, I forgot this last week, but if I were clicking a few things this week:

chart of ETH issuance over time

A review of hardware for eth staking

MyCrypto’s history of Eth hard forks to celebrate 10m blocks

I might also check out the stuff about personal tokens, because personal money is an interesting subject to think about, even if you’re skeptical like I am.  The idea of “what is money” can take you down some fun intellectual rabbit holes: 

75 interesting uses of social money by Roll 

Personal tokens were the topic du jour, check out this overview from Dan Finlay

A little light this week on the high-level stuff.  The chart of Eth issuance I already discussed.  The hardware for Eth staking is a worthwhile jumping off point if you’re planning on staking.   And the hard fork history is worth knowing, or if you know it, then it’s a fun trip down memory lane.

Eth1

Step by step guide to running a Hyperledger Besu node on mainnet

Nethermind v1.18.30 query the chain and trace transactions within minutes with Beam sync

A primer on block witnesses

Installation guide to running eth1 nodes (or eth2 testnet) on RaspberryPi4

So this week we have a guide to running the ConseSys’s Besu client (part of Hyperledger) which is a Java client aimed at enterprise, but which can run mainnet.   More Nethermind and Besu nodes are good for client diversity.  So is OpenEthereum (formerly known as Parity), which had a release yesterday.

And if you like running nodes on RaspberryPi4, check that out.

This newsletter is made possible by Celer!

Celer has just released a new state channel mainnet upgrade enabling everyone to easily run a layer-2 state channel node and to utilize the low-cost and real-time transactions enabled by Celer. Game developers with no blockchain knowledge today monetize their games through CelerX gaming SDK that leverages the underlying layer-2 scaling technology with ease. Celer has also released the world’s first skill-based real money game apps where players can join multi-player game tournaments and win cryptocurrency prizes, Follow us on twitter, blog, discord and telegram.

Yay, thanks Celer! 

Eth2

Danny Ryan’s latest quick eth2 update – bug bounties doubled, latest IETF BLS standard

PegaSys’s Teku client is now syncing the Schlesi testnet – which has been much more stable than expected

Latest Prysmatic client update – reducing RAM usage, slashing protection

SigmaPrime’s Beacon fuzzer update, struct-aware, bugs found in Teku and Nimbus

Latest Eth2 networking call, gossipsub v1.1. Ben’s notes

Python notebook to simulate a network partition

Apostille, an Eth1x64 variant

Scoping what is necessary to port eth1 to an eth2 shard and turn off proof of work

Lots of talk of go-live this week. Is it July, q3, or q4?  We need to get audit reports and have multi-client testnets running long-term, though last I checked the Schlesi testnet has been quite stable.  And since publishing the newsletter, now PegaSys’s Teku client is fully validating on Schlesi.

Quorum v2.6 – breaking database schema changes, update to geth v1.9.x

Microsoft continues to make the Ethereum dev experience better, with their VScode extension. 

Governance, DAOs, and standards

How to start a MolochDAO

Options for delegated voting in KyberDAO

EIP2633: Formalized upgradable governance

EIP2628: Header in StatusMessage

I oppose any sort of “formalized upgradeable governance” and I think most do.

Application layer

Use POAP for sybil-resistant voting or to determine Discord channel access

Yield: a revised implementation of Dan Robinson’s yTokens for fixed rate, fixed term loans that give a yield curve

Comparing total value locked in DeFi to unique active addresses

75 interesting uses of social money by Roll

Personal tokens were the topic du jour, check out this overview from Dan Finlay

Strike: perpetual swaps with 20x leverage

POAP as a quasi-KYC layer is pretty interesting to me.  Seems like there are some good uses in Ethereum land.

i’m excited to hear that DeFi will get a yield curve!

Tokens/Business/Regulation

Nic Carter: are stablecoins parasitic or beneficial?

OpenRaise: a continuous offering fundraiser for DAOs

dxDAO’s kickstarter using OpenRaise sold out before public announcement – though the curve is still live, plus a secondary Uniswap market

dxDao’s token is an interesting bit.  Most of the token supply goes to the DXDAO, but it’s an interesting experiment in building completely decentralized apps as a Dao with a community that lately has been burgeoning.  It’s also a bit of a check on rent-seeking because it is a credible threat to excessive fees.

One fun note is that the Uniswap market occurred almost immediately and (almost by definition) trades at a substantial discount to the main market.

General

Aggregatable Subvector Commitments, the future may not involve Merkle trees

This week, Ethereum mined its 10 millionth block.

Here’s MyCrypto’s history of Eth hard forks to celebrate 10m blocks

IPFS releases Testground suite for p2p networking tests

PayPal blocked tokenized real estate startup RealT despite a lack of chargebacks, so they’re switching to Wyre

10,000,000 blocks of Ethereum mainnet!

Capricious censorship in web2 and payments!  I’ve been in PayPal’s shoes managing a card not present merchant account, and so I’m somewhat understanding to them.  You’re trying to keep your fraud rate down in a system that sometimes seems rigged against you.  In RealT’s case, they likely also had large amounts coming through which combined with crypto seems scary to Paypal, even with a low chargeback rate.  

It’s not really anyone’s fault.  The system sucks, and this is why Ethereum matters.

Final note that you can see below in the calendar: RAC’s $TAPE dropped yesterday.  It’s a tradable ERC20 token sold on Uniswap (ie, a pre-set price curve).   Of course the price went from $20 to $1000, as the token is redeemable for a limited edition cassette tape of RAC’s new album Boy.

Protocol

At EthCC, Vitalik announced PlasmaCash. [Outside, Karl Floersch was giving an abbreviated talk on the steps]. This design framework -- coins deposited on Plasma chain as NFT thus you can track only Merkle branches for your own coins -- comes from Plasma with much less per-user data checking in last week's issue.

Karl released a PlasmaCash spec.

VB: "Plasma is not a sidechain/drivechain. Sidechains and drivechains let 50% of the miners on the sidechain steal all coins in the side/drive chain. Plasma relies only on the security of the main chain"

I'm thankful that ConsenSys has brought me on as an employee and given me time to do this newsletter.

Editorial control is 100% me.  Blame me first and last.

Ethereum Enterprise Alliance (EEA) launches.  Press release

NYTimes compares EEA to Hyperledger for supply chains.

Tyler Smith: Supply chains will be production before finance, due to data sensitivity requirements. [Context] 

Microsoft announces Quorum: EEA Implementation on Azure

Where Vitalik hopes the EEA will contribute (zk-snarks, contract safety, testing)

String Labs: future private chain systems will be dependent upon services from public chain

Vlad Zamfir tweeted a polemic: "Ethereum isn't safe or scalable. It is immature experimental tech. Don't rely on it for mission critical apps unless absolutely necessary!"

Context: the euphoria that happens in some parts of the Ethereum community when there's a price runup.

Arguably his comments to Bloomberg should have been equally as anti-euphoria. [But boo to the reporter for using Vlad's intellectual integrity as a gotcha]

Ethereum Foundation priorities: 1) more revenue [not as much a concern now after the price runup], 2) more researchers [double the team?], 3) better communication

I imagine there will be significant FUD in coming months about this Vitalik quote, so let's print it in entirety:

"I would only endorse [mutability] in the gravest of circumstances (a fair schelling point is IMO when the value at stake exceeds the cost of a 51% attack, which was incidentally pretty close to $50 million in my estimates back when the DAO fork took place, though IMO it's not a good idea to have any level at which the possibility of fork recovery is 100% for moral hazard reasons"
