How does Blockchain work and how can it change our lives?

How can Blockchain tech work?

Before attempting to understand how blockchain ledgers operate, it might be worth having a look at traditional ledgers. For centuries, banks have utilized ledgers to keep databases of account transactions, and governments have utilized them to keep records of property ownership. There’s a central authority — that the bank or government office — that manages changes of all transactions, so that they could identify who owns what, at any given time. This allows them to check whether new transactions are valid, that the same $1 isn’t spent twice and houses aren’t offered by people who don’t own them.

Since users trust the manager of this ledger to check the trades properly, people can buy and sell from each other even when they have not met before and don’t trust each other. The middleman also controls access to information regarding the ledger. They may decide that everyone can find out who owns a construction, but only account holders can check their balance. These ledgers are centralized (there’s a middleman, reliable by all customers, who has total control over the system and mediates every trade) and black-boxed (that the functioning of the ledger and its information aren’t completely visible to its customers).

Digitization has made these ledgers faster and simpler to use, however they remain centralized and black-boxed. Blockchain delivers exactly the same record-keeping performance but without a centralized architecture. The issue is how it may be sure that a trade is legitimate when there isn’t any central authority to check it. Blockchains fix this problem by decentralizing the ledger, so that each user retains a copy of it. Everyone can request that any transaction be added into the blockchain, but transactions are only accepted if most of the users agree that it’s legitimate, e.g. that the request comes from the authorized person, that the house seller has not already sold the home, and the buyer has not already spent the cash. This checking is performed reliably and automatically on behalf of each user, creating a extremely fast and secure ledger system that is remarkably tamper-proof.

Each new transaction to be recorded is bundled together with other brand new trades to a ‘block’, which is inserted as the latest link on a lengthy ‘chain’ of historic trades. This chain forms the blockchain ledger that’s held by all users. This work is known as ‘mining’. Anybody can become a miner and compete to be the first to solve the intricate mathematical problem of creating a legitimate encrypted block of trades to add to the blockchain.

You will find numerous means of incentivizing people to do this job. Most frequently, the first miner to make a valid block and then add it to the series is rewarded with the amount of fees for its transactions. Fees are currently about $0.10 per transaction, but cubes are added regularly and contain thousands of transactions.

Miners may also receive new money that’s created and put into circulation as an inflation mechanism. Including a new block to the series means updating the ledger that’s held by all users. Users just accept a brand new block when it has been verified that all of its trades are valid. If a discrepancy is found, the block is reversed. The block is additional and will remain there as a permanent public record. No user can eliminate it. There can be no ‘imitation ledger’ since all users have their own real version to check against. These blockchains are described as ‘permission-less’, since there’s no special authority that could deny permission to participate in the checking and adding of transactions.

It’s also possible to install ‘permissioned’ blockchains, in which a limited group of actors retain the capability to access, assess and add transactions to the ledger. This enables ‘mainstream’ actors such as banks and governments to keep substantial control over their blockchains.

How Blockchain technology could change our own lives

Blockchains are a remarkably clear and decentralized way of recording lists of trades. Their best-known use is for digital currencies like Bitcoin, which declared blockchain technologies to the world using a headline-grabbing 1000 percent increase in value at the course of one month at 2013. This bubble quickly burst, but steady expansion since 2015 means Bitcoins are currently valued higher than previously. There are many different means of utilizing blockchains to make new currencies. countless such currencies are made with different features and aims.

How Blockchain-based currency transactions create fast, economical and secure public records means that they also can be utilized for several non-financial tasks, like casting votes in elections or demonstrating that a document existed at a particular moment.

Blockchains are particularly well suited to situations where it is imperative to understand ownership histories. As an example, they can help manage supply chains better, to provide certainty that diamonds are ethically sourced, that clothes aren’t made in sweatshops which champagne comes from Champagne. They could help finally resolve the problem of video and music piracy, while allowing digital media to be legitimately bought, sold, inherited and given away secondhand such as novels, video and vinyl tapes. They also present opportunities in all sorts of public services such as health and welfare obligations and, in the frontier of both blockchain development, are self-executing contracts paving the way for companies that run themselves with no human intervention. Blockchains shift some management over daily interactions with technology away from fundamental elites, redistributing it among users. In doing so, they create systems more transparent and, perhaps, much more democratic. Nevertheless, this won’t likely not result in a revolution. Indeed, the authorities and business giants investing heavily in blockchain development and research aren’t trying to make themselves obsolete, but to enhance their services.

There are additionally some wider issues to consider. For instance, blockchain’s transparency is good for matters of public record such as land registries, but what about bank accounts and other sensitive data? It is possible (albeit just occasionally and with significant effort), to recognize the people associated with transactions. This could compromise their privacy and anonymity. While some blockchains do provide full anonymity, some sensitive information simply shouldn’t be distributed in this way. Nevertheless, although blockchains aren’t the solution for every issue and even though they will not revolutionize every aspect of our own lives, they might have a substantial effect in several places and it is crucial to be ready for the challenges and opportunities they pose.


A brief guide to Initial Coin Offerings (ICO)

Initial​ ​Coin​ Offerings​ ​(ICO)

The introduction of Bitcoin in 2009 gave us resources and infrastructure to transact primitive digital tokens of value (bitcoin in the event of the Bitcoin blockchain) over the open public internet without trusted intermediaries. However, so as to create new tokens one either needed to scale and deploy a new blockchain network (likely forked from Bitcoin), or problem tokens on top of an existing blockchain network like Bitcoin (through metadata encoded into raw transactions). The former was an uphill struggle due to challenges of scaling and achieving network effects to get a new blockchain, and the latter was challenging due to the complexities of trying to encode sufficient information related to new tokens into raw Bitcoin transactions. Neither model was perfect.

But with the introduction of Ethereum in 2015 arrived the the Ethereum blockchain not only provided the infrastructure for transacting primitive digital tokens (ether in this case) but also provided the capability for easily creating and autonomously managing other secondary electronic tokens of value within the open public internet without reliable intermediaries.

Applying this concept of smart contracts, which can be effectively applications running a top a decentralized network, tokens can be generated and allocated to users, and made to be readily tradable. This process of creating tokens and distributing them to customers in exchange for a network’s primitive electronic token (cryptocurrency) is called an ICO process, and can be viewed as a novel distribution channel for assets.

Not all tokens are created equal

This post Isn’t supposed to be an introduction to the technically rich world of cryptography, blockchains and consensus mechanisms, for which there are numerous excellent entry level resources. However, the key point to bear in mind is that secondary tokens are not like primitive tokens (cryptocurrencies such as bitcoin and ether) that are inherent to the “structural integrity” of a blockchain network.

Open peer-to-peer worth transfer networks, for example Bitcoin or Ethereum, need to endure complex attack vectors within an open hostile environment – where all parties (hosting or accessing the community) are assumed to be self interested and focused on optimizing their own value. In this scenario the key question is how do all parties be incentivized to work for the greater good of securing the community while fulfilling their self-interest. This leads us into the real innovation of this blockchain network, the primitive token (or cryptocurrency).

In addition to being the subject of transaction between parties On the network (the users), the crude token is also used to incentive key parties competing to reach consensus (the miners) as quickly as possible on the state of this blockchain ledger (i.e. who owns what primitive token). The reward for securing the network and reaching consensus is either new supply of crude tokens or transaction fees. In this model, trust is made from mistrust through expending energy in the mining process, which makes the violation of the “sanctity of the blockchain ledger” costly and economically unfavorable to the option of procuring the system and being rewarded in the native store of value for the effort of doing this . It is a self-contained system that is simple and beautiful in its implementation, and requires no more controls and rules than are necessary.

Here you can see the core purpose and the unique nature of a cryptocurrency, and why it is fundamental to a blockchain network: cryptocurrency is the atomic element where the open public blockchain network is forged. On the other hand a secondary token, that is made in addition to a blockchain network, is merely a representation of some “property rights” that may (or may not) be external to the blockchain e.g. “real world assets” or access to products/services.

Inherent blockchain and its cryptocurrency to create and issue (through an ICO procedure) secondary tokens for any purpose, but this only uses the open public blockchain as an independent “custody or notarization” data layer.

ICO and token issuance

Among the most obvious and natural use cases for ICO based Secondary token issuances is to represent some form of conventional security e.g. equity, debt, participation in profit sharing, etc.. In addition to issuance, allocation and transferability being programmed into an immutable smart arrangement, one can also predefine a set of events like cash flow rules which could be triggered either at set times or by particular external events. There are a number of reasons why a public blockchain infrastructure is logical for the issuance and management of financial securities, which are mostly associated with custody regulations around how client money and asset are managed through their life cycle.

However, since the “offer and sale” of securities is in and Of itself highly controlled, many models have been devised by startups to allow the issuance of tokens through an ICO distribution version whilst not falling afoul of securities regulations. As well as the question around whether a token is a security or not there are also lots of other unanswered questions related to tax of capital gains and KYC/AML rules. These are a few of the regulatory and statutory financial considerations which are currently an ongoing area of development and appraisal.

Recent SEC investigative report, these aspects will be the most crucial on how ICO And the issued tokens are classified by regulators globally.

Implications of Blockchain in Securities industry

The exploration of Blockchain applications in the securities Industry has already begun and seems possible to pick up steam in the next several years. Many financial institutions have created in-house teams and study labs to construct and examine Blockchain networks, or are working together with third party sellers specializing in this space. In addition, companies have sought to participate in collaborative efforts with consortia to develop a frequent Blockchain frame and make industry standards.

The used cases of Blockchain applications are between the equity, debt and derivative markets. Since the implementation of these Blockchain applications advances, issues are being raised concerning how processes involving Blockchain fit within the present regulatory framework. In light of the trends, this section highlights some key factors linked to Blockchain execution and regulation.

Implementation Considerations

Developing Blockchain applications in the securities Industry can present many challenges. In trying to overcome those challenges, some of the essential considerations for market participants in executing a Blockchain network may consist of governance, operational architecture and community security.


One of the key governance principles of the Bitcoin Network Was to establish a “trustless” environment open to the general public, where no single party is responsible for, or enabled with, governing and operating the network. Although this kind of network may offer certain advantages like providing a decentralized system which isn’t dependent on any particular party to operate, it may also pose some vulnerability in case it contributes to inefficient management of the machine. As an instance, recent events have shown that lack of a central governing body for its evolving Bitcoin Network has generated concerns for the system, as participants try to ascertain an approach to handle greater transaction volume. Therefore, a Blockchain network dependent on the use of a trustless system, where no party is responsible or liable for the appropriate operation of the machine, may pose risks to investors and markets. Many market participants are working to use private Blockchain networks using a governance structure that takes into consideration that participants in the network are generally known and trusted parties.

When setting up or engaging in a private Blockchain Network, in which multiple organizations across the sector are involved, a number of the first governance questions that need to be answered relate to the operation of the network and deciding that bears responsibility for it. Below are the types of questions that market participants may wish to consider when creating a governance structure to get a Blockchain network.

· Can the governance arrangement for the Blockchain system be determined by a single entity or a set of firms? How would the pursuits of end-users, that aren’t participants on the community, be represented?

· Who would be responsible for ensuring adherence by amateurs to the prerequisites established for the Blockchain network, and how could this be ran?

· Who would be accountable for the day-to-day operation of this system and resolving any technical problems on the network?

· Who would be responsible for setting and maintaining a affordable business continuity plan (BCP) to your network, to address some unanticipated emergencies or significant business disruptions?

· How would any conflicts of interest in the performance of or participation on the community be addressed?

· How would mistakes or omissions about the Blockchain be mirrored or rectified?

Operational Structure

A Vital concern for market participants in executing a Blockchain system is discovering the operational structure of the network. The operational structure of a Blockchain system would normally include creating a framework for: (1) network participant access and related on-boarding and off-boarding processes; (2) trade validation; (3) asset representation; and (4) data and transparency demands. Following are a few locations that market participants may want to consider when creating such a framework.

On-boarding, Off-boarding and accessibility:

It is vital for a Blockchain system to launch, as portion of its operational infrastructure, the standards and processes for establishing and keeping participating members and determining their level of access. Especially, in developing a Blockchain community, applicable parties may Want to think about how they would:

· Establish eligibility standards for participants to gain access to the network;

· Establish a vetting and on-boarding procedure for new participants, including establishing an identity verification process and executing proper user arrangements prior to on-boarding;

· Grow an off-boarding process for participants that may be non-compliant or disqualified for violating securities laws, rules and regulations or for violating system rules; and establish exclusion criteria to discover previous participants which might have been disqualified;

· Memorialize the terms of engagement and code of conduct required from all participants;

· Establish varying degrees of access for different player groups (e.g., direct network participants . indirect users running transactions via direct participants)–that might include restricted access to certain data sets, and even constraints on ability to read or write about the shared ledger; and when the network includes global participants or entities from different countries, it may be desired to present special focus on regulatory requirements in those various jurisdictions, particularly as it relates to privacy and information sharing; and

· Determine which sort of access would be given to regulators.

Transaction validation:

As previously described different kinds of methodologies before launching a transaction identification methodology, network operators are most likely to evaluate the advantages and disadvantages of each methodology. In doing this analysis, some prospective questions network operators might desire to consider are mentioned below.

· If consensus-based, would it take a proof-of-concept or would it be an easy consensus algorithm? How much latency and sophistication would that add to the validation process? What is the risk of collusion by multiple parties to validate a fraudulent transaction?

· In case single-node verifier (i.e., one single node will be responsible for confirming all transactions), how would that verifier be determined? Is the simplicity and speed of a single-node verifier value the concentration of risk? What would be the backup or recovery process in the event the single-node is unavailable or endangered?

· How would the amount of nodes needed for verification be determined? If other nodes or arbitrary nodes are put up as verifiers, how could the order be established? Does this procedure expose the network to possible dangers from a number of nodes?

· What procedure will the system embrace to rectify or correct any erroneous entry that may be recorded on the shared ledgers?

Asset representation:

To the extent an asset is represented on a Blockchain network, Operators will need to determine how those assets will be based on the community. Following are a few factors operators may want to take into account in the investigation.

Will assets be directly issued and digitally represented on The system? Or would they be issued in traditional form and subsequently tokenized on the community? Would the network consider both kinds of asset representation?

• If tokenized, what extra security dangers and complexities are posed? How would any loss or theft of the conventional off-chain advantage be managed? How would asset fluctuations (e.g., stock splits and conversions) be handled?

• Will the network only permit new advantage issuance or can it allow on-boarding of present assets?

How would money be represented on this network? Industry participants are contemplating a variety of versions to ease the cash aspect of a transaction settlement. For instance, in a recent effort, a few banks are tinkering to create a virtual “settlement coin.”

• If cash-backed settlement tokens are utilized, would these tokens be termed as virtual money? Could there likely be a scenario where multiple such native tokens are made by various networks or companies? In that case, are they tradable?

• If fiat money (i.e., money that’s created by the authorities of a country to be utilized as cash) is used and settlement happens off the system through a conventional cash payment process, how, when, and from whom will the trade and asset transfer be recorded on the network?

• How will a participant’s ability to fulfill the money obligation be determined? Can a deposit be accumulated from network participants to be utilised in the event of non-payment? How will this type of deposit be calculated?
