Negli anni passati, le transazioni erano comunemente facilitate dalle banche, presentando il rischio di insolvenza di questi intermediari. Per affrontare questa preoccupazione, è emersa la tecnologia blockchain, che facilita le transazioni monetarie in cui i partecipanti stessi agiscono come garanti. Questa assicurazione viene realizzata attraverso il coinvolgimento di tutti gli utenti della blockchain, ridefinendo la fiducia nelle transazioni facendo affidamento sulla validazione dei blocchi e sulla partecipazione degli utenti per mantenere l’integrità del sistema. Mantenere un equilibrio stabile tra i validatori di blocchi e gli utenti è imperativo per la sostenibilità della blockchain. La blockchain opera principalmente attraverso due sistemi: Proof of Work (PoW) e Proof of Stake (PoS). Il PoW si basa sul potere computazionale utilizzato dai validatori per convalidare le transazioni, mentre il PoS sfrutta il possesso di valuta all’interno della blockchain per convalidare le transazioni. Questa analisi approfondisce i modelli di compensazione per i validatori e gli utenti, esaminando l’equilibrio tra il numero di validatori, utenti nelle transazioni e relativi payoff. Queste variabili sono fondamentali per garantire la stabilità e la longevità della blockchain, con considerazioni distinte per i sistemi PoW e PoS.

Abstract
In prior years, transactions were commonly facilitated by banks, posing the risk of default by these intermediaries. To address this concern, blockchain technology has emerged, facilitating currency transactions where participants themselves act as guarantors. This assurance is achieved through the involvement of all blockchain users, redefining trust in transactions by relying on block validation and user participation to uphold the system’s integrity. Maintaining a stable equilibrium between block validators and users is imperative for the blockchain’s sustainability. The blockchain primarily operates through two systems: Proof of Work (PoW) and Proof of Stake (PoS). PoW relies on the computational power utilized by validators to validate transactions, while PoS leverages ownership of currency within the blockchain to validate transactions. This analysis delves into compensation models for validators and users, examining the balance between the number of validators, users in transactions and payoffs. These variables are pivotal for ensuring the stability and longevity of the blockchain, with distinct considerations for PoW and PoS systems.File | Dimensione | Formato | |
