Bank of America (NYSE:BAC), the second-largest bank in the United States by assets, has applied for a blockchain-related patent associated with the development of a new cryptocurrency wallet. The latest patent, entitled “Multi-Tiered Digital Wallet Security,” is the latest in a string of over 60  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.

BofA filed with the US Patent and Trademark Office (USPTO) for “facilitating multi-tiered digital wallet security where users may be able to hold their digital currency more safely and securely as compared to existing digital wallet infrastructure.”

Combining usability with high-level privacy, anonymity, and security, the proposed wallet may be further secured by a multi-signature contract which requires the entry of passwords and/or biometric data by each user before access to the central core.

The latest BofA patent also describes a new system where signature passwords may be entered only by users located within a particular geographical region.

The proposed patent mimics the core idea of multisig e-wallets, which require a transaction to have two or more signatures before it can be executed, a security layer that reduces the risk of fraud. However, the filing says existing crypto wallets either require users to maintain their own private keys or trusting the third parties to ensure the safety of their private keys. Such arrangements involve the risk of forgetting or mishandling private keys and thus losing access to their digital wallets, it says.

Open to Blockchain, skeptical over  Cryptocurrencies  Cryptocurrencies By using cryptography, virtual currencies, known as cryptocurrencies, are nearly counterfeit-proof digital currencies that are built on blockchain technology. Comprised of decentralized networks, blockchain technology is not overseen by a central authority.Therefore, cryptocurrencies function in a decentralized nature which theoretically makes them immune to government interference. The term, cryptocurrency derives from the origin of the encryption techniques that are employed to secure the networks which are used to authenticate blockchain technology. Cryptocurrencies can be thought of as systems that accept online payments which are denoted as “tokens.” Tokens are represented as internal ledger entries in blockchain technology while the term crypto is used to depict cryptographic methods and encryption algorithms such as public-private key pairs, various hashing functions, and an elliptical curve. Every cryptocurrency transaction that occurs is logged in a web-based ledger with blockchain technology.These then must be approved by a disparate network of individual nodes (computers that maintain a copy of the ledger). For every new block generated, the block must first be authenticated and confirmed ‘approved’ by each node, which makes forging the transactional history of cryptocurrencies nearly impossible. The World’s First CryptoBitcoin became the first blockchain-based cryptocurrency and to this day is still the most demanded cryptocurrency and the most valued. Bitcoin still contributes the majority of the overall cryptocurrency market volume, though several other cryptos have grown in popularity in recent years.Indeed, out of the wake of Bitcoin, iterations of Bitcoin became prevalent which resulted in a multitude of newly created or cloned cryptocurrencies. Contending cryptocurrencies that emerged after Bitcoin’s success is referred to as ‘altcoins’ and they refer to cryptocurrencies such as Bitcoin, Peercoin, Namecoin, Ethereum, Ripple, Stellar, and Dash. Cryptocurrencies promise a wide range of technological innovations that have yet to be structured into being. Simplified payments between two parties without the need for a middle man is one aspect while leveraging blockchain technology to minimize transaction and processing fees for banks is another. Of course, cryptocurrencies have their disadvantages too. This includes issues of tax evasion, money laundering, and other illicit online activities where anonymity is a dire ingredient in solicitous and fraudulent activities.

The document further explains that through the wallet, the user may be able to hold tokens, funds, or any other asset associated with a decentralized P2P system. Furthermore, the user may be able to use the wallet to request performance of network-specific functions related to the P2P system such as asset transfers.

“The digital wallet interface may further include a plurality of wallet tiers which may provide additional logical abstraction layers through which users may associate and access portions of their digital currency,” it adds.

The proposed “multi-tiered wallet interface” marks the latest in a string of BofA’s investments into the technology that underpins cryptocurrencies, after it has filed over 66 related patents through August of this year. Bank of America is already the largest holder of blockchain-related patents in the United States, surpassing tech giants like Microsoft.

Still, while the lender has filed this impressive number of blockchain patents, with inventions ranging from crypto-powered ATMs to storage for private keys, it doesn’t necessarily mean that each patent will result in a working product.

And more importantly, while the bank is taking the lead on blockchain innovations, it has joined other lenders in seeking to distance itself from the cryptocurrency space. Specifically, BofA last year banned its clients from all cryptocurrency purchases using their credit cards.
