The size of the full Bitcoin blockchain exceeded gigabytes of data on September 19, according to Blockchain. This is the size of the full Bitcoin transaction history for the past 10 years. While this amount of data might seem significant, a terabyte hard drive would easily cover it—and continue to do so for another decade or two. In contrast, an archival node on the Ethereum blockchain is already over five terabytes in size—and increasing at record speeds with growing block sizes —although a pruned node comes in at just GB.

How secure is blockchain really?


Blockchain is transforming everything from payments transactions to how money is raised in the private market. Will the traditional banking industry embrace this technology or be replaced by it?

Blockchain technology has received a lot of attention over the last decade, propelling beyond the praise of niche Bitcoin fanatics and into the mainstream conversation of banking experts and investors.

Someone is going to get killed. It is a vehicle to perpetrate fraud. Despite the skepticism, the question of whether blockchain and decentralized ledger technology DLT will replace or revolutionize elements of the banking system remains. And this very loud and public backlash against cryptocurrencies from banks begs another question: What do banks have to be afraid of? Blockchain technology provides a way for untrusted parties to come to agreement on the state of a database, without using a middleman.

By providing a ledger that nobody administers, a blockchain could provide specific financial services — like payments or securitization — without the need for a bank. Read on for a deep dive into how blockchain technology could turn the traditional banking industry on its head while enabling new business models through technology.

To learn about the other industries blockchain is affecting, take a look at our article on 58 industries blockchain could disrupt. Today, trillions of dollars slosh around the world via an antiquated system of slow payments and added fees. The number of confirmed Bitcoin transactions per day has grown 6x from just over 50, in to over , as of February Source: Blockchain.

Facilitating payments is highly profitable for banks, providing them with little incentive to lower fees. Cryptocurrencies like bitcoin and ether are built on public blockchains Bitcoin and Ethereum , respectively that anyone can use to send and receive money.

In this way, public blockchains cut down on the need for trusted third parties to verify transactions and give people around the world access to fast, cheap, and borderless payments. Bitcoin transactions take 10 minutes on average to settle, although this can lengthen to hours or even days in extreme cases. And due to their decentralized and complex nature, crypto-based transactions are difficult for governments and regulatory bodies to control, observe, and shut down.

Developers are also working on scaling cheaper solutions to process crypto transactions more quickly. While cryptocurrencies are a long way from completely replacing fiat currencies like the US dollar when it comes to payments, the last couple of years have seen mostly upward growth in transaction volume for cryptocurrencies like bitcoin and ether. Some companies are using blockchain technology to improve B2B payments in developing economies.

One example is BitPesa , which facilitates blockchain-based payments in countries like Kenya, Nigeria, and Uganda. BitPesa is also widely used for remittances sent throughout sub-Saharan Africa, the most expensive region in the world for sending money. Blockchain companies are also focusing on enabling businesses to be able to accept cryptocurrencies as payment.

For example, BitPay , a payment service provider that helps merchants accept and store bitcoin payments, has a number of integrations with e-commerce platforms like Shopify and WooCommerce.

Ethereum-based payments platform Airfox , which was acquired by Brazil-based retailer Via Varejo in May , has partnered with MasterCard to allow customers to pay using its banQi app at global points of sale, as well as at every Via Varejo location.

Consumers in the country can now pay using the HUPAYX mobile app and point-of-sale infrastructure at over , stores, including duty-free stores and shopping complexes. Blockchain technology is also being used to facilitate micropayments, which represent amounts usually less than a dollar.

For instance, SatoshiPay , an online cryptocurrency wallet, allows users to pay tiny amounts to access paid online content on a pay-per-view basis. Users can load their wallet with bitcoin, US dollars, or any other payment token supported by the app. One big reason behind the coming disruption of the payments industry is the fact that the infrastructure supporting it is just as liable to disruption — the world of clearance and settlements.

The fact that an average bank transfer — as described above — takes 3 days to settle has a lot to do with the way our financial infrastructure was built. Moving money around the world is a logistical nightmare for the banks themselves. Today, a simple bank transfer — from one account to another — has to bypass a complicated system of intermediaries, from correspondent banks to custodial services, before it ever reaches any kind of destination.

The two bank balances have to be reconciled across a global financial system, comprised of a wide network of traders, funds, asset managers, and more. Each correspondent bank maintains different ledgers, at the originating bank and the receiving bank, which means that these different ledgers have to be reconciled at the end of the day.

The actual money is then processed through a system of intermediaries. Each intermediary adds additional cost to the transaction and creates a potential point of failure. That means that instead of having to rely on a network of custodial services and correspondent banks, transactions could be settled directly on a public blockchain. This stands in contrast to current banking systems, which clear and settle a transaction days after a payment. That might help alleviate the high costs of maintaining a global network of correspondent banks.

Ripple , an enterprise blockchain services provider, is the most prominent player working on clearance and settlement. While the company is best known for its associated cryptocurrency XRP, the venture-backed company itself is building out blockchain-based solutions for banks to use for clearance and settlement.

Ripple currently has over customers in over 40 countries signed up to experiment with its blockchain network. If a trader in Mexico wants to send money to their counterpart in the US, a traditional bank transaction would require that both traders have local currency accounts in the countries they wish to receive their money in.

The trader in Mexico can simply use Mexican pesos to buy XRP tokens through the exchange to pay their American counterpart.

And this entire transaction can happen in a fraction of a second, Ripple claims. R3 is another major player working on distributed ledger technology for banks. While SNB plans to expand the trial to cross-border payments in , it has not yet decided whether to issue its own central bank digital currency. Projects like Ripple and R3 are working with traditional banks to bring greater efficiency to the sector.

Blockchain projects are doing more than just making existing processes more efficient, however. The fundraising space is a notable example of this. Raising money through venture capital is an arduous process. Entrepreneurs put together decks, sit through countless meetings with partners, and endure long negotiations over equity and valuation in the hopes of exchanging some chunk of their company for a check.

In contrast, some companies are raising funds via initial coin offerings ICOs , powered by public blockchains like Ethereum and Bitcoin. In an ICO, projects sell tokens, or coins, in exchange for funding often denominated in bitcoin or ether. The value of the token is — at least in theory — tied to the success of the blockchain company. Investing in tokens is a way for investors to bet directly on usage and value.

Through ICOs, blockchain companies can short-circuit the conventional fundraising process by selling tokens directly to the public.

Some high-profile ICOs have raised hundreds of millions — even billions — of dollars before proof of a viable product. After soaring in early , ICO funding has since fallen significantly. At the same time, initial coin offerings represent a paradigm shift in how companies finance development. First, ICOs occur globally and online, giving companies access to an exponentially larger pool of investors. Second, ICOs give companies immediate access to liquidity. Compare that to 10 years for venture-backed startups.

Venture capital firms have taken notice, with Sequoia , Andreessen Horowitz , and Union Square Ventures , among others, all directly investing in ICOs, as well as gaining exposure by investing in cryptocurrency hedge funds. And I hope it does. The democratization of everything is what has excited me about technology from the beginning. The idea behind the ICO is to sell tokens to users and bootstrap a payment platform on top of the messaging network.

If, as blockchain advocates predict, the next Facebook, Google, and Amazon are built around decentralized protocols and launched via ICO, it will eat directly into investment banking margins.

Several promising blockchain companies have emerged around this space. Companies like CoinList , which began as a collaboration between Protocol Labs and AngelList, are bringing digital assets to the mainstream by helping blockchain companies structure legal and compliant ICOs. CoinList has developed a bank-grade compliance process that blockchain companies can access through a streamlined API, helping projects ensure everything from due diligence to investor accreditation.

Investment banks today are experimenting with automation to help eliminate the thousands of work hours that go into an IPO. And CoinList is just the start. A number of companies are emerging around the new ICO ecosystem, from Waves , a platform for storing, managing, and issuing digital assets, to Republic.

Of course — given regulatory pronouncements — ICO activity should be taken with a grain of salt, and the bubble of unregulated ICOs largely burst after This is not just limited to company fundraising, but also to the underlying fabric of securities.

The Blockchain 50 is our first-ever ranking of the 50 most promising companies within the blockchain ecosystem. To buy or sell assets like stocks, debt, and commodities, you need a way to keep track of who owns what.

Financial markets today accomplish this through a complex chain of brokers, exchanges, central security depositories, clearinghouses, and custodian banks. These different parties have been built around an outdated system of paper ownership that is not only slow, but can be inaccurate and prone to deception. Say you want to buy a share of Apple stock. You might place an order through a stock exchange, which matches you with a seller.

So we outsource the shares to custodian banks for safekeeping. To settle and clear an order on an exchange involves multiple intermediaries and points of failure. In practice, that means that when you buy or sell an asset, that order is relayed through a whole bunch of third parties. Transferring ownership is complicated because each party maintains their own version of the truth in a separate ledger.

Because there are so many different parties involved, transactions often have to be manually validated. Each party charges a fee. Blockchain technology promises to revolutionize financial markets by creating a decentralized database of unique, digital assets. The potential for disruption is massive. While fees are typically lower than. Using blockchain technology, tokenized securities have the potential to cut out middlemen such as custodian banks altogether, lowering asset exchange fees.

Source: Trefis. Further, through smart contracts, tokenized securities can work as programmable equity — paying out dividends or performing stock buybacks through a couple lines of code. Finally, putting real-world assets on blockchain technology has the potential to usher in broader, global access to markets. Polymath is one of the blockchain technology companies that wants to help migrate trillions of dollars of financial securities to the blockchain.
