History of Soldo

Soldo was the name of an Italian medieval silver coin, issued for the first time in the late 12th century at Milan by Emperor Henry VI.

It quickly became widespread in Italy where it was coined in Genoa, Bologna, and numerous other cities.

In Venice, the soldo was minted from the reign of Francesco Dandolo onward, remaining in use until 1862.

As time passed, the soldo started to be coined in billon and, from the 18th century, in copper.

Every input in a transaction refers to a unique output. Soldo is designed to mitigate the risks associated with key re-usage and one-input-to-one-output tracing. Every address for a payment is a unique one-time key, derived from both the sender’s and the recipient’s data.


Untraceable anonymous Soldo transactions and encrypted information transfers in decentralized p2p network.

Untraceable payments

The ordinary digital signature verification process involves the public key of the signer. It is a necessary, because the signature actually proves that the author possesses the corresponding secret key. But it is not always a sufficient condition. Soldo uses more sophisticated scheme - ring signatures.

Unlinkable transactions

Anyone can check all your incoming transactions when you post your public address, even if they are hidden behind a ring signature. To avoid linking CryptoNote creating multiple unique one-time keys, derived from the single public key, for each p2p payment. No third party can discover the link between the one-time key generated by the sender and the receiver’s unique public address. One-time key is always different even if the sender and the receiver both remain the same.

Double-spending proof

All users keep the list of the used key images and immediately reject any new ring signature with a duplicate key image. It will not identify the misbehaving user, but it does prevent any double-spending attempts, caused by malicious intentions or software errors.

Proof of work

Soldo brings the equality with an egalitarian proof-of-work algorithm, which is perfectly suitable for ordinary PCs. It utilizes built-in CPU instructions, which are very hard and too expensive to implement in special purpose devices or fast memory-on-chip devices with low latency.
