HOW DOES A PEER-TO-PEER PAYMENT PROTOCOL WORK, AND WHAT IS IT?

Payment protocols known as peer-to-peer (P2P) allow direct transactions between two parties without using middlemen like banks or payment processors. Since no middlemen are involved, peer-to-peer payment methods boost security through cryptographic encryptions and offer lower transaction fees.

In the crypto environment, P2P protocols built on blockchain are frequently employed. P2P payment users go through a generally streamlined process to create a wallet and link it to the platform of their choice. Sending money is simple: Type the recipient's wallet address and amount, then click "Send."

After the transaction is started, validators examine it and add it to the block, a decentralized ledger containing all blocks of data and where the term "blockchain" originates. The monies can then be used or transferred at will by the recipient.

IS BITCOIN ACTUALLY A P2P PROTOCOL?

Satoshi Nakamoto, the pseudonymous creator of Bitcoin (BTC), labeled the original cryptocurrency as "peer-to-peer electronic cash" in its white paper. However, that definition needs a deeper look.

Accurate P2P payment systems should allow senders and receivers to complete transactions without middlemen. Bitcoin "miners," or blockchain nodes, broker transactions. Bitcoin transactions require mediation by miners. Thus consumers cannot transact without an internet connection. It's more accurate to say Bitcoin runs on a peer-to-peer network since it's not a payment method.

HOW COME SATOSHI NAKAMOTO CALLED BITCOIN "PEER-TO-PEER ELECTRONIC CASH"?

For Bitcoin's P2P network, "peer-to-peer" means that nodes communicate and verify transactions directly.

Bitcoin is an "electronic" currency because it only exists in the digital world and isn't a physical commodity like traditional money. By referring to Bitcoin as "cash," the term most people use to describe the widely accepted and easily transferable type of money, Nakamoto stressed the usage of Bitcoin as a daily transaction currency. Nakamoto intended for Bitcoin to take the place of conventional fiat money.

ARE THERE ANY OTHER DIGITAL PAYMENT SYSTEMS?

Today's digital payment systems all need middlemen to complete transactions. The most popular intermediary for bank transfers is a bank. When using a point-of-sale (POS) device, credit card issuers operate as the middlemen in transactions between the cardholder and the retailer.

The system of the credit card firm is connected to both the POS equipment and the credit card. Therefore, all credit card users won't be able to pay for a haircut or buy coffee in case of a system shutdown. When all users depend on a single system to fulfill their daily payment needs, this is a single point of failure.

WHAT MIGHT BE REQUIRED FOR CBDCS TO BE DEEMED PEER-TO-PEER?

A country's fiat currency may be issued and controlled digitally as a central bank digital currency (abbreviated CBDC). Offline payments are essential for increasing financial inclusion and are particularly important for CBDCs. Owners of CBDC must be able to communicate with one another without an internet connection. This is crucial for those with lower income levels who might be unable to utilize CBDCs online because they need an internet membership.

Physical currency stands out most for its P2P payment capabilities, enabling users to exchange value directly. Maintaining this feature while providing offline payments is vital if digitizing and replacing paper-based cash is the goal.

MACHINE-TO-MACHINE COMMERCE: WHAT IS IT, AND HOW CAN IT BENEFIT FROM P2P PAYMENTS?

Machine-to-machine (M2M) commerce will soon be enabled by Internet of Things (IoT) equipment like intelligent fridges and electric cars that automatically settle their bills with one another. For instance, refrigerators order food and beverages as needed, and electric vehicles charge themselves at charging points.

Because they are already issued and governed by the government, CBDCs can be utilized to facilitate these M2M transactions in a secure environment. IoT devices can be linked to their owners' wallets so they can make pre-approved purchases independently.

The M2M commerce sector is anticipated to nearly double from $37 billion in 2023 to $57 billion in 2032, a growth that will come with a heavy transactional burden. The world will need an infrastructure that can handle billions of transactions per second in the future of M2M commerce. Having an intermediate merely makes the payment network more worn out. The demands of the potential volume of M2M trade will require an accurate P2P payment system.

ARE THESE PEER-TO-PEER PROTOCOLS EVEN NEEDED?

Yes. Automation and decentralization are enabled by P2P protocols for blockchain and smart contracts. P2P transactions are "peer-to-peer," which improves security and anonymity and facilitates cross-border and international business transactions, promoting globalization and acceptance. By removing third parties, they reduce transaction costs and speed up processing. For finance to keep up with the digital age, full peer-to-peer facilitation is necessary.

IS THERE REALLY A P2P PAYMENT SOLUTION OUT THERE?

With its flagship product, MetaMUI, Sovereign Wallet, an identity-based blockchain technology business focused on digital asset management and identification solutions, offers a genuine peer-to-peer solution. A peer-to-peer protocol called MetaMUI allows for direct cross-border payments, offline transactions, and M2M commerce without middlemen.

By integrating MetaMUI, CBDCs can do business without a connection to the internet. Users of the MetaMUI CBDC could send money directly to people in other countries who were using separate MetaMUI CBDCs without using settlement currencies or any regulatory restrictions.

MetaMUI's chain code uses edge computing, or data processing and computation closer to the data source, like IoT devices, instead of slow centralized servers or the cloud. Edge computing provides P2P M2M commerce utilizing the MetaMUI CBDC to execute intelligent contracts directly between devices.
