Simplified Payment Verification: Lightweight Bitcoin Verification

Simplified Payment Verification (SPV) is an easy way to verify blockchain transactions.

What is Simplified Payment Verification (SPV)?

The Short for Simplified Payment Verification, SPV is a lightweight way to verify blockchain payments that load only the Blockchain Hashes and asks for proof of included in the Merkle tree.

The Merkle trees are cryptographic structures that consist of the labeling system in cryptography, with one name for every nonleaf and other tree. A Merkle tree is an architecture in cryptography in which all children have its own child nodes as well as it has to be identified by his uniquely designated symbols: The SPVs can help determine the fact that a transaction has been included in a BTC. LIGHT client refers to light clients’ wallets running on low-end systems.

At the same time, SPVs verify whether a transaction was executed. The role of SPVs can greatly simplify the process. It is worth noting that only 80 bytes per block need to be stored, as opposed to the much larger size required on large nodes.

SPV has a cybersecurity downside. In the case of a 51% cryptocurrency attack, hackers may be able to inducing SPV proof-of-concept to confirm illegal transactions by creating an artificial proof-of-concept that confirms illegal transactions. Research is underway to reduce the threat of such scenarios. Nakamoto’s whitepaper states that Bitcoin transactions can be confirmed without running a full network of nodes. The White Paper, which is included in the publication “Bitcoin” by Nakamoto, claims that it is possible to verify bitcoin transactions without running a full network of nodes.
