They are secure because, on a blockchain, there is no one single point of failure; the code exists on every node in the network. This means that there is no one place that the code can be manipulated without all the others on the network noticing. Within popular media, the prototypical system used to explain blockchain is the bitcoin network. But this is just one type of solution in this space. It is useful to think of three main types of blockchain, or "distributed ledger".
This chart illustrates them:. Permission-less ledgers have unique design goals — mainly the need to operate in a completely open environment without any points of centralised trust, and in which potentially malicious actors are not only allowed to submit transactions but also participate in transaction validation.
For this reason, in the consensus protocol layer, an extra hurdle is added: The approach is computationally expensive, uses a significant amount of electricity, does not scale well and requires many network participants to be able to generate the trust required to ensure the network operates effectively. These systems need in-depth analysis involving reward models, game theory and behavioural economics.
Permissioned ledgers are based on a set of trusted transactions processors and validators who are also the only parties allowed to take part in the consensus mechanism. They are distributed in a precisely controlled fashion and can be equally robust in rejecting un-authorised transactions or changes.
This makes corrupting the ledger extremely difficult. More importantly, in comparison to permission-less systems like bitcoin, they require substantially less computational capacity and energy to run. Private distributed ledgers restrict the people who can submit transactions and access blockchain data to an explicit whitelist of identified participants.
This is suitable for regulated environments. Permissioned and public In the centre of the chart above, we can see a third type of distributed ledger — a form of hybrid system that enables the combination of some of the benefits of permissioned, private, shared systems and others from the permission-less. Blockchain exists at the cross-over between economics and technology. To apply it effectively, we need to understand both sides of its personality. The economics of a system will affect the technical design and vice versa.
Its unique properties can provide new opportunities for wider economic and social objectives, but these need to be carefully handled, as the risks are shared by whole economies and societies.

In all blockchain transactions, there are four fundamental components: This chart illustrates them: Listed below are some unique projects that have raised funding via an ICO or plan to hold a token sale in the near future:.
The democratic access to investment that ICOs foster is reflected also in the variety of projects that people choose to fund and participate in. Here are some of the projects that have been supported in the past, as well as a few that are coming up in the near future. The Ethereum blockchain is a distributed smart-contract platform fueled by a native digital currency called ether.
It was one of the first successful ICOs in the space and laid the groundwork for how many of them have worked since.
It also created the Ethereum blockchain platform, upon which many of the following decentralized applications DApps and projects are being built. Golem aims to create a distributed, global supercomputer using blockchain technology.
The token itself will be used as the medium of exchange for computing power on the network. Qtum pronounced Quantum is a Turing-complete blockchain stack with smart-contract capability. Their biggest innovation is the implementation of a proof-of-stake protocol, as opposed to the energy-intensive proof-of-work protocol employed by the Bitcoin and Ethereum blockchains.
Qtum has only released a testnet thus far, but they concluded their crowdsale on March That funding will be used to finish the development of the mainnet and other future upgrades. It was comparable to a large joined bank account. That ether, in turn, would have been used to fund future projects that DAO token holders deemed investment-worthy. People who purchased DAO tokens would get to vote on how The DAO would allocate resources and what projects and contracts it would take on or fund.
Perhaps nothing better illustrates how visionary the project was than the way in which they raised awareness for the crowdsale.
Through that grassroots effort, The DAO managed to raise Being such a successful token sale and raising so much publicity came with one major drawback: Unfortunately a bug was discovered, and a hacker was the first to discover it, which led to approximately 3.
The majority of the money was repaid to investors by means of the infamous Ethereum Hard Fork, which led to the creation of Ethereum Classic. An innovator in the field of venture capitalism, Blockchain Capital BCAP is looking to help fund the next great initiatives in the digital arena.
The portfolio that BCAP maintains is impressive. With current investments in big names like Coinbase, Bitfury, Ripple and ShapeShift, BCAP stands to be an accelerating force for innovation in the infrastructure of blockchain technology.
A DGX token is an on-chain proof of ownership of 1 gram of Augur , which launched its token sale in July of , functions as a decentralized platform for prediction markets.
By decentralizing the markets, it allows the average person to gain access to them. This therefore creates a more accurate predictive engine due to the wider swath of people participating and investing in their predictions. What makes Augur especially innovative is that it also allows the average person to make his or her own prediction market, centered around an event or idea of their choosing.
An important distinction to make is that Augur itself is not a prediction market. Rather, it is an open-source code atop which markets can be built. The amount of tokens an investor ultimately ended up with was determined by the percentage their investment made up of the total crowdsale and how early they participated.
Instead, owners of REP are expected to report on the outcomes of events within Augur every few weeks. Those who report inaccurate outcomes will forfeit some REP, and their forfeited REP will be distributed among those who reported accurate outcomes. Gnosis is a platform for creating prediction markets and is a direct competitor of Augur.
According to the Gnosis white paper , WIZ tokens will also function as the payment medium for GnosisPremium, a platform that will be actively supported by developers and allow for stable coins, customization tools and other premium features. Gnosis will also offer a free platform, GnosisBasic, that will not be actively supported by developers and will have a less robust user interface.
Kik recently entered the digital asset arena with the announcement of their own token , Kin. This announcement may signal the transition of digital asset tokens into mainstream commerce. Kik currently claims a base of over million users, a figure which includes 40 percent of American teens. Even though Kik has such a large user base, it has been difficult to monetize their digital services, and therefore innovate at a competitive level with the social media giants like Facebook and Twitter, who get much of their revenue through advertisements.
The Kin token itself will ideally be used in a multitude of ways by different companies, including Kik, all aiming to create a digital interactive environment based on the currency. According to the Kin white paper , there are already foreseeable uses of the token in the Kik app. These include establishing VIP chat groups that require an entrance fee payable in Kin to enter, allowing premium, user-generated content to be accessed using Kin, and allowing users to highlight their messages in groups for a fee, among many others.
Kik plans to sell 1 trillion Kin during its ICO event. Kik has not yet given any indication as to when this ICO will occur. Poet , short for Proof of Existence 2. Poet lets users generate an immutable ownership certificate for digital content, track and license content on the web and on the blockchain, discover new content, and verify the authenticity and authorized use of all available content.
