Another result of the PoW mechanism is that tampering the transaction history recorded on the blockchain requires a significant resource investment, reducing the financial viability of such attacks. Aiming at widespread adoption in enterprise settings, less resource-intensive mechanisms have been developed and implemented. Given that within business networks and enterprises, there is already an initial degree of trust between the participants, a high degree of decentralisation of trust is often traded for less resource intensive consensus mechanisms. If designed accordingly, private blockchains do not consume more energy than traditional database solutions.
