Jax.Network. Learn how this novel blockchain design solves the problem of scalability leveraging merged mining and sharding.
A Scalable, Decentralized Stablecoin for DeFi. Join the Jax.Network.
A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) is secured and bound to each other using cryptographic principles (i.e. chain).
So, what is so special about it and why are we saying that it has industry-disrupting capabilities?
The blockchain network has no central authority — it is the very definition of a democratized system. Since it is a shared and immutable ledger, the information in it is open for anyone and everyone to see. Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.
QuarkChain is a blockchain that focuses on scalability, security, and decentralization. It uses a two-layered system with a sharded layer for distributing data across chains to allow high throughput and a root layer to confirm blocks. This structure is designed to handle millions of transactions per second and solve scalability limitations. QuarkChain also focuses on decentralization through game-theoretic mining incentives that align individual miners' benefits with the overall system. Additionally, varying rewards across chains ensures similar returns for solo and pooled miners, preventing centralization.
Quarkchain is a two-layered blockchain that allows for resharding and horizontal scalability. It uses multiple shards to process transactions independently and in parallel, allowing throughput to scale linearly with the number of shards. The second layer confirms blocks from the sharded chains. Cross-shard transactions can be confirmed in minutes, and users only need a single account to interact with multiple shards. It also supports smart contracts through use of the Ethereum Virtual Machine.
The document discusses distributed blockchain processing and some of the challenges involved. It addresses issues like race conditions when sharing resources across distributed systems and consistency problems that can arise. It proposes using a distributed hash table (DHT) combined with a blockchain to help control consistency across nodes. This could provide benefits like uniformly distributing transactions across nodes, weakening the dependency of execution time on the number of nodes, enabling real-time transactions, and allowing the blockchain to be independently validated. The approach aims to help address issues like consistency when replicating data or operations over distributed resources.

Introduction
Business blockchain requirements vary. Some uses require rapid network consensus
systems and short block confirmation times before being added to the chain. For others,
a slower processing time may be acceptable in exchange for lower levels of required
trust. Scalability, confidentiality, compliance, workflow complexity, and even security
requirements differ drastically across industries and uses. Each of these requirements, and
many others, represent a potentially unique optimization point for the technology.
For these reasons, Hyperledger incubates and promotes a range of business blockchain
technologies including distributed ledgers, smart contract engines, client libraries, graphical
interfaces, utility libraries, and sample applications. Hyperledger’s umbrella strategy
encourages the re-use of common building blocks via a modular architectural framework.
This enables rapid innovation of distributed ledger technology (DLT), common functional
modules, and the interfaces between them. The benefits of this modular approach include
extensibility, flexibility, and the ability for any component to be modified independently
without affecting the rest of the system.
The Lightning Network aims to solve Bitcoin's problems of slow payments, high transaction costs, and poor scalability. It allows for instant, very low-cost payments between nodes by conducting transactions off-blockchain through payment channels.

Доклад разработчиков Exonum на третьем митапе сообщества блокчейн-разработчик...Дмитрий Плахов
This document discusses using the Exonum framework to build blockchain-driven web applications. Exonum is an extensible framework that allows building blockchain projects using a Byzantine Fault Tolerant algorithm, light clients, anchoring to hashes, and the Rust programming language. It describes how a traditional web application architecture relies on a centralized admin, whereas a blockchain-driven one using Exonum distributes trust across multiple nodes reaching consensus. Users would authenticate using public/private key pairs and directly control and sign transactions to modify their own data on the blockchain, improving security, transparency and fault tolerance compared to traditional architectures.
Nodes are copies of blockchains that allow users to view cryptocurrency transaction histories. While only one node is needed to preserve a blockchain, typically hundreds or thousands of nodes are used to improve security. Blockchains consist of linked blocks that record transactions in a way that prevents retroactive alteration without changing all subsequent blocks. This allows transactions to be verified across decentralized networks. Mining involves validating transactions and adding them to the blockchain in exchange for rewards.

This digital era is all about scalability, and with blockchain and cryptocurrency gaining traction, there are more concerns about their scalability. Most of the well-known crypto projects have scalability issues in terms of the time and cost required to complete a transaction.
The efficiency of a project is strongly influenced by its scalability. Users will always choose the network with the lowest cost and fastest speed for performing a particular transaction. For example, an NFT transfer on the Ethereum network will cost up to $6, whereas an NFT transfer on the Polygon will just cost $0.00055.
Scalability has evolved as a major concern for blockchain networks desiring to stay relevant in the highly competitive crypto market. As a result, the developer community is working on Sharding, a database partitioning technique used to improve the blockchain’s scalability and capacity. It enables blockchains to execute more transactions per second. Let’s have a detailed look at it.
What is Sharding?
Sharding is simply a partitioning technique used to distribute computational and storage effort across a peer-to-peer (P2P) network so that each node is not responsible for handling the network's transactional load. It divides a blockchain’s entire network into smaller partitions known as "shards." Each shard is made up of its own data, making it different from other shards. Instead of a node storing all the information, each node stores only information about its division or shard.
Sharding is used by blockchain companies to increase scalability by processing more transactions per second. Every node can still view every ledger entry; they just don't process and retain every piece of data. This means that a shard's information can still be shared among other shards, keeping the ledger safe and decentralized.
How does Sharding work?
To understand how sharding works within a blockchain network, it's important to know how data is stored and processed. A blockchain can be viewed as a network consisting of nodes. The blockchain nodes are completely autonomous entities that are responsible for handling all network activities, data, and transactions. Each node in a blockchain network is in charge of storing, processing, or managing the entire volume of transactions that occur within the network.
Since each transaction is stored on each node, this significantly slows down transaction processing on a blockchain. The transactional burden of a blockchain network can be partitioned or distributed via sharding, which can be beneficial because it means that each node in the network does not have to manage or process the entire blockchain's workload. Sharding divides the workload into sections called "shards" so that it can be managed more efficiently.
Sharding is done by horizontally partitioning databases and dividing them into rows. The rows are conceptualized as shards based on their characteristics.
Hyperledger Sawtooth Lake Intel's OSS Contribution to Enterprise BlockchainAltoros
Sawtooth Lake is an open source distributed ledger project within Hyperledger. It uses a blockchain architecture where each node holds a copy of the shared ledger and transactions are grouped into blocks and chained together cryptographically. Sawtooth Lake allows for modular transaction families that encapsulate business logic and smart contracts. The latest release focuses on improvements to transaction processing, including parallel execution and multi-language support.
Blockchain technology, initially the backbone of cryptocurrencies like Bitcoin, has evolved beyond its original purpose to become a transformative force in the digital world. It’s no longer just a ledger for financial transactions; blockchain is a foundational technology with potential applications across various sectors, from finance to healthcare and beyond.
This evolution has been marked by significant advancements that address blockchain’s initial limitations, such as scalability, interoperability, and privacy. These improvements are catalyzing a shift in how blockchain is utilized, paving the way for more efficient and user-centric decentralized applications (dApps) and platforms.
This report provides a brief yet comprehensive exploration of these technological breakthroughs. We aim to dissect how each development contributes to the evolving landscape of blockchain, highlighting its potential to revolutionize diverse sectors. Our focus will cover a spectrum of advancements: scalability solutions and consensus mechanisms to privacy enhancements, smart contract innovations, tokenization, and the burgeoning field of Decentralized Finance (DeFi).

Blockchain Ecosystem and Cryptocurrency RegulationsAmir Rafati
A blockchain is a general digital ledger of transactions that are executed on the network, e.g. using Bitcoin to buy a cup of coffee is a transaction.
All users of the network, ‘Nodes’, have a copy of the transaction records and can access them freely, a role previously played by centralized institutions. Therefore, the blockchain network is ‘decentralized’.

The document provides an overview of the Lattice Network, which uses a multidimensional block lattice architecture and quantum virtual machines to support smart contracts. Key points:
- Lattice Network uses a block lattice structure like Nano to achieve high transaction throughput and scalability. It further develops this with a multidimensional block lattice and smart contract support.
- The network aims to provide a decentralized Network as a Service (NaaS) platform through features like routing nodes, storage nodes, and security functions.
- Smart contracts are supported through smart contract blocks on the transaction ledger and an internal asset ledger. Transactions are recorded on user blockchains and smart contract instances can be deployed.
- The network uses
NEAR is based on the Delegated Proof of Stake (DPoS) consensus algorithm and uses sharding to optimize performance. However, unlike sharding in other cryptocurrencies like Polkadot, all SHARDS NEAR are treated as part of the same blockchain. In addition, NEAR uses Rainbow Bridge to provide interaction with Ethereum. The integrity of the blockchain is guaranteed by the Nightshade mechanism because only a summary of the current status of each shard is added to the block in the NEAR blockchain. Each shard maintains its own set of validator nodes that exceed their shard status whenever a block is generated.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Essentials of Automations: Exploring Attributes & Automation Parameters
What is the JaxNet protocol?
1. What is the JaxNet Protocol
and the Concepts of Merged
Mining & Sharding?
jax.network
2. The global economy needs a currency that is
decentralized and built on a scalable blockchain
network.
The JaxNet protocol comes as the solution to
the scalability problems hindering the mass
adoption of cryptos.
This novel blockchain design solves the problem
by leveraging merged mining and sharding.
jax.network
3. The JaxNet protocol is a scalable blockchain
system whose Proof-of-Work consensus
mechanism is built on sharding and
merged-mining solutions.
This protocol has a high throughput with low
transaction fees. Therefore, it’s safer to
transfer value with JAX, the native token of the
JaxNet ecosystem.
The JaxNet Protocol
jax.network
4. It’s more than just a blockchain innovation. It
epitomizes the quest for a scalable, secure, and
decentralized blockchain network.
The JaxNet protocol satisfies four major criteria
in the blockchain space, including:
Decentralization
Scalability
Security, and
Stability
Decentralized, stable, and scalable JAX coins
jax.network
6. JaxNet is based on the Proof-of-Work protocol,
specifically built as the solution to the
Scalability Trilemma in blockchain networks.
It can achieve more scalability by leveraging
the concept of sharding.
The JaxNet protocol architecture, sharding & merged mining
jax.network
7. For security reasons, it's often said that
sharding doesn't work best on the PoW
networks, however, Jax.Network managed to do
that.
Its shards are secured from take-over attacks
due to the process of merged mining.
The JaxNet protocol architecture, sharding & merged mining
jax.network
8. Sharding is an essential component of the
JaxNet architecture. Technically speaking, it is
the process of splitting a database horizontally
to distribute the load on the system evenly.
Sharding helps to reduce network congestion
while increasing a throughput by creating new
chains called shards.
Sharding in the JaxNet protocol
jax.network
9. Specifically, the sharding concept deployed in
the JaxNet ecosystem helps blockchain nodes
to bypass most of the storage and network
traffic requirements.
Sharding also helps to remove the bottlenecks
of block propagation delay.
These features all contribute to improving the
scalability and decentralization of the JaxNet
protocol.

10. Merged mining is simply the process of mining
two or more digital currencies at the same time,
as in the case of Namecoin, which can be
merged-mined along with Bitcoin.
Merged mining in the JaxNet protocol
jax.network
11. As for JaxNet, the merged mining technique
employed in the network allows for the mining
of one or more shards simultaneously.
This adds an extra layer of security to the
shards against 51 percent attacks.
Merged mining in the JaxNet protocol
jax.network
12. More like an incentive for miners, the reward
function employed in the network distributes
rewards to miners in accordance with the hash
power committed to maintaining the network.
All of these features play a significant role in
ensuring the scalability and security
of the network.
Merged mining in the JaxNet protocol
jax.network
13. No other project has ever managed to address
all three aspects of the Scalability Trilemma on
the Proof-of-Work protocol without sacrificing
decentralization, but JaxNet did that efficiently.
Merged mining in the JaxNet protocol
jax.network
14. With its revolutionary approach to the problems
of blockchain technology, the JaxNet protocol
can lead to the mass adoption of blockchain.
By creating a unique blockchain-based digital
payment ecosystem and leveraging the
concepts of merged mining and sharding,
Jax.Network is undoubtedly heading in the right
direction.
