Chain will be discontinuing its free Bitcoin API service as part of its shift to  Blockchain  Blockchain Blockchain comprises a digital network of blocks with a comprehensive ledger of transactions made in a cryptocurrency such as Bitcoin or other altcoins.One of the signature features of blockchain is that it is maintained across more than one computer. The ledger can be public or private (permissioned.) In this sense, blockchain is immune to the manipulation of data making it not only open but verifiable. Because a blockchain is stored across a network of computers, it is very difficult to tamper with. The Evolution of BlockchainBlockchain was originally invented by an individual or group of people under the name of Satoshi Nakamoto in 2008. The purpose of blockchain was originally to serve as the public transaction ledger of Bitcoin, the world’s first cryptocurrency.In particular, bundles of transaction data, called “blocks”, are added to the ledger in a chronological fashion, forming a “chain.” These blocks include things like date, time, dollar amount, and (in some cases) the public addresses of the sender and the receiver.The computers responsible for upholding a blockchain network are called “nodes.” These nodes carry out the duties necessary to confirm the transactions and add them to the ledger. In exchange for their work, the nodes receive rewards in the form of crypto tokens.By storing data via a peer-to-peer network (P2P), blockchain controls for a wide range of risks that are traditionally inherent with data being held centrally.Of note, P2P blockchain networks lack centralized points of vulnerability. Consequently, hackers cannot exploit these networks via normalized means nor does the network possess a central failure point.In order to hack or alter a blockchain’s ledger, more than half of the nodes must be compromised. Looking ahead, blockchain technology is an area of extensive research across multiple industries, including financial services and payments, among others.

The startup recently secured $30 million in venture investment, which stands as the biggest round in the industry during the past 7 months.

Around the time of its previous round of $9.5 million one year ago, Chain was more engaged with the Bitcoin blockchain’s underlying infrastructure, offering services to interact with the blockchain in real-time using its nodes and API.

But over the past year, it has transitioned into what has become the hottest trend in the crypto industry in 2015: blockchain technology for securities and fiat  Payments  Payments One of the bases of mediums of exchange in the modern world, a payment constitutes the transfer of a legal currency or equivalent from one party in exchange for goods or services to another entity. The payments industry has become a fixture of modern commerce, though the players involved and means of exchange have dramatically shifted over time.In particular, a party making a payment is referred to as a payer, with the payee reflecting the individual or entity receiving the payment. Most commonly the basis of exchange involves fiat currency or legal tender, be it in the form of cash, credit or bank transfers, debit, or checks. While typically associated with cash transfers, payments can also be made in anything of perceived value, be it stock or bartering – though this is far more limited today than it has been in the past.The Largest Players in the Payments IndustryFor most individuals, the payments industry is dominated currently by card companies such as Visa or Mastercard, which facilitate the use of credit or debit expenditures. More recently, this industry has seen the rise of Peer-to-Peer (P2P) payments services, which have gained tremendous traction in Europe, the United States, and Asia, among other continents.One of the biggest parameters for payments is timing, which looms as a crucial element for execution. By this metric, consumer demand incentivizes technology that prioritizes the fastest payment execution.This can help explain the preference for debit and credit payments overtaking check or money orders, which in previous decades were much more commonly utilized. A multi-billion-dollar industry, the payments space has seen some of the most innovation and advances in recent years as companies look to push contactless technology with faster execution times.

Bitcoin’s blockchain and other improvised distributed ledger systems are envisioned to cut costs, eliminate counterparty risk and greatly reduce settlement times for securities trades.

The indication is that the company’s work with Bitcoin thus far can be leveraged for its new ambitions. CEO Adam Ludwin said, “As we move into 2016, we will be folding our bitcoin capabilities into this enterprise platform. We will no longer support free projects on the bitcoin network.”

The service will end on December 31. The startup is offering assistance from its CTO for those who want to migrate their Bitcoin apps to other free or low-cost API services.
