With this initiative, the municipality on the banks of the Ceresio strengthens one's vocation “crypto-friendly city”, i.e. a pole of reference within the sphere of blockchain technology.
As you know, a blockchain consists of a set of capable technologies to record transactions in one chain of blocks which keep memory and proof of it (be they purchases, contracts, agreements, and so on).
one of the crucial aspects di this technology is the verification of every transaction made by a decentralized network, what makes this type of immutable, therefore stable and secure digital exchange.

A sustainable technical solution also in terms of energy
The most common applications of this technology they have a limit energy expenditure.
Lugano wanted to overcome that limit with a sustainable technical solution in energy terms, also eliminating the expense fees for citizens and traders.
La identified solution is the creation of one institutional network guarantor of transactions that allows the evolution from a "validation algorithm" to a “authority algorithm”.
The authority of the partners in fact guarantees the blockchain to operate without the need to carry out costly computer controls which generally constitute the main cause of a increased energy consumption.
Thus Lugano has evolved into the most dynamic Swiss digital hotspot
