Velocity

It consists of a three-stage verification of each block registered in the network, thus preventing double spend, very common in several currencies.

Adaptive Block Size(ABS)

Spero does not have a specific block size, so regardless of the number of transactions, all of them will go into the block if they are within 60 seconds of the last creation.

OP_RETURN

With this feature you can store up to 240 bytes of information directly in the blockchain.

About Us

We are a Brazilian cryptocurrencie, created in the city of Belo Horizonte / MG.
Know a little more about our ideas.

Our Mission

Reduce the social and economic differences of the underprivileged population across the globe.
This leads to improvement in quality of life where it is scarce or does not exist.

We create a currency with use in a market accessible to all and a bank without charges of abusive fees, maintaining only the fixed rate of network transaction (~ 0.0001 SPERO).
With this we will have the first Bank and Social Market maintained entirely by a crypto-currency.

Our Vision

With mutual help and companionship we can achieve a goal that many people try to do alone.
The little ones, when they come together, become giants.

Technical Characteristics

Know the technical information of our software technology.

Algorithm

This algorithm uses 13 rounds of hashing with 13 different hash-functions (blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, etc.), which makes it one of most reliable in a modern cryptocurrencies world.

Hybrid mining PoW and PoS

With Spero you mining with proof of work(PoW[ASIC, GPU, CPU, etc]) and also mining just leaving your wallet with active balance online, open and unlocked, the well-known proof of stake(PoS).

Total Coins

There are 7 million coins total, and were pre-mined 100,000 for application in several areas of the project.

Encrypted Message (E2M)

With Spero you can send encrypted messages to other users, having in hand only the address and the public key of the recipient.
