How Blockchain Can Tackle the Issue of Double-spending of Bitcoin

Blockchain technology has achieved significant popularity ever since it came into existence. The technology has also started getting acceptance all across the world in a gradual manner. Blockchain-controlled cryptocurrencies have led to a sort of revolution in terms of digital currency usage. Cryptocurrencies have gone a long way in redefining the way money is used. The entire world is now slowly moving towards the direction of decentralized digital currency. We have got the opportunity of using digital currency at several locations. Apart from the various advantages that digital currency offers, some disadvantages have also plagued it, and double-spending is one of the major issues. Given below are some of the vital points related to blockchain technology and double spending:

How Can Blockchain Help You Make Error-free Transactions?

Blockchain can effectively enhance the efficiency of digital transactions by letting people and companies carry out direct digital transactions sans any intermediaries. It helps in bringing down the cost, boosts the security of the transaction, and helps in making the system far more transparent.

What is Double-spending?

Double-spending can be defined as the risk associated with a digital currency that may be spent twofold by an individual or organization. It has emerged as one of the graves yet unique problems linked to the decentralized digital currencies. The possibility of double-spending surges as digital information can be conveniently replicated effortlessly by tech-savvy people who have acquired a detailed understanding of the blockchain network along with computer power required for manipulating it.

Physical currencies do not face this problem as it is not that simple to replicate them. Additionally, the parties included in the transaction can instantly verify their authenticity and earlier ownership of physical currencies without much hassle.

It is worth noting that double spending takes place when a blockchain network gets interrupted, and cryptocurrencies are robbed. The robber may send a copy of the currency transaction in a bid to make it appear authentic or may remove the transaction altogether. When a cryptocurrency is not effectively secured in a wallet, it will be robbed. However, it is not a common phenomenon.

The common ways of double-spending are when a blockchain robber sends several packets to the network, thus reversing the transaction so that it appears as if it never took place.

Is Double Spending an Issue?

Digital money differs from cash. The moment you carry out a transaction with digital cash, you broadcast the transaction to available nodes in the network. Nodes can be defined as computers that run the software on which the digital currency is supported. The nodes are required to receive and verify the transaction and it is a time-taking procedure. The real problem arises here. It faces the issue of stopping somebody from copying the transaction and rebroadcasting it before it has been verified on the network. The network may face the issue of ascertaining the transaction, whether it is genuine or fake.

How Blockchain Proves Effective in Solving Double Spending?

The emergence of Blockchain technology has proved to be highly effective in various aspects and tackling the issue of double-spending is one of them. It can effectively eliminate all the bottlenecks that prevail in the conventional technology that we have been using. When we discuss the problems linked to cryptocurrency, Blockchain can solve this by applying a confirmation mechanism along with a global ledger that is distributed to all peers in the network.

Blockchain has become the central technology of all existing cryptocurrencies, and it is available with features that make this technology an indispensable one. Whatever transactions or data exchange occur at this platform will have the data stored in sequential order along with time-stamping. It will ease the process of tracing the information. All the transactions are cross-checked by nodes, and only after this, it will enter the global ledger. The transaction which gets the highest confirmations from miners will be included in Blockchain while the others will be rejected. The merchants receive the advice to wait for a minimum of six confirmations.

Bitcoin’s Timestamp Server:

A white paper by Satoshi Nakamoto’s advised usage of a timestamp service as an effective solution to curb the issue of double-spending. The server secures a hash of block transactions and highlights the hash to all existing nodes in the Bitcoin network. The main function of a timestamp is to prove that all available data in the hash couldn’t be established after the hash got published. Each timestamp will include an earlier timestamp in its hash. It builds an immutable record of the order in which transactions will occur.


Therefore, we can conclude here that Blockchain can significantly eliminate double spending woes by way of timestamping groups of transactions. It then highlights the transactions to all nodes in the Bitcoin network. Because the transactions get time-stamped on Blockchain and linked to earlier ones, it will be near impossible to tamper with them.
