A CRYPTO FOUNDATION FOR THE NEW ECONOMY

Nexa is operating at the bleeding edge of blockchain technology and finance to
enable new frontiers of freedom and sovereignty.



Get involved!






KEY FEATURES


GLOBAL CAPACITY

Thanks to Nexa’s unique PoW algorithm, Nexa will scale to over 10 billion
transactions per day. That’s enough capacity for the whole planet. No high fees
and no waiting around for your transaction to be secured. This is thanks to new
technology to remove the bottlenecks of bandwidth, storage and computation speed
of nodes.


NATIVE TOKENS

Tokens are a market-validated use case for cryptocurrency which will bring
significant amounts of value and network usage to Nexa. This is why Nexa offers
token functionality natively without any need for special smart-contracts or
token standards like ERC-20. But if you need the full power of smart-contracts
for your token, Nexa has that too.


NATIVE NFTS

NFTs can be created much like fungible tokens on Nexa. These can be used for
endless exciting functions including: digital artwork, asset ownership, tickets,
in-game items, certificates or all sorts of yet to be discovered use cases. All
the same incredible functionality open to tokens is also available to NFTs,
meaning the sky’s the limit.


WISE-CONTRACTS

Nexa uses an ultra-scalable smart-contract system which enables practically
everything possible on an EVM chain without the major scaling bottlenecks
suffered by turing-complete networks. We call these ‘wise-contracts’ because not
only are they smart, but also wise in how network resources are used.


POW-SCALING

Nexa’s Proof-of-Work algorithm uses the enormous scaling power of mining
incentives to bring new hardware into existence. It incentivises the creation of
hardware that nodes will make use of to accelerate transaction validation to a
speed not seen on any other blockchain.


INSTANT TRANSACTIONS

Transactions are instantly sent across the network, thanks to the miner rules of
the network this is enough security for certain transactions. Soon a new
technology will be brought to Nexa that enables instant, trustless transactions
of any amount. Anyone will be able to choose to have their payments credited
instantly.








GLOBAL CAPACITY

We must provide enough capacity for every person on the planet to provide true,
revolutionary value. This is why scaling plays a pivotal role in Nexa’s
strategy.




THE KEY BOTTLENECKS


BANDWIDTH

How much data is sent between nodes.


SPEED

How quickly can nodes validate transactions.


STORAGE

How much data is needed to store the blockchain.




BANDWIDTH SOLUTION

❤️


INITIAL BLOCKCHAIN SYNC

Initial download of the full chain.

Nexa miners will include a hash in each block which proves the full UTXO set at
that point in time.

This is called a ‘UTXO Commitment’ & will allow new nodes to join the network
without having to download the full blockchain.



❤️


CONTINUOUS BLOCKCHAIN SYNC

Continual download & upload of new transactions and blocks.

Propagation of new blocks only requires sending a tiny amount of data no matter
the size of blocks thanks to a technology called ‘Graphene’.

Nodes only need to know the transactions they are missing to validate a block.




SPEED SOLUTION

❤️


SHA256 HASHING

Creating hashes of data.

SHA256 hashing is found throughout the Nexa protocol, in transactions and of
course the PoW algorithm. By hardware accelerating this function, it will be
possible for nodes to process billions of hashes per second.



❤️


SIGNATURE CREATION & VERIFICATION

Creating new signatures & checking they are valid.

Schnorr signatures are also found in every transaction in Nexa. They are also a
compute-heavy operation. By hardware accelerating this function, nodes will be
able to process millions of signatures per second.

❤️


UTXO LOOKUPS

Looking up data from within the UTXO set.

To validate transactions and blocks, Nexa nodes must constantly check the UTXO
set for data. By hardware accelerating this process, nodes will be able to
handle hundreds of thousands of transactions per second, possibly even more.






STORAGE SOLUTION


❤️

By using UTXO commitments, nodes will only need to store the UTXO set of the
blockchain.



The UTXO set should grow linearly with the number of users and usage, and
requires only a tiny fraction of the storage that a full blockchain needs.












INSTANT TRANSACTIONS

Transactions on Nexa are propagated across the network in sub-seconds using
0-conf technology. This means there’s no waiting around for your transaction to
be delivered. This may be enough security for certain situations, if not block
times are just 2 minutes to accumulate the extra security required.



There are plans for an opt-in, non-protocol layer, instant transaction
technology to be brought to Nexa later in 2023. This will use the powerful and
efficient features of Nexa’s wise-contracts to provide a trustless service to
those who want to use it.












NATIVE TOKENS

Tokens on Nexa get the 1st class treatment. Creating and managing tokens is done
just like sending NEX without any need for special smart-contracts. Your new
project can create a token on Nexa with 1 click.



Tokens also get full access to the smart-contract capabilities of Nexa.

NATIVE NFTS

Creating NFTs of all types is just as easy as creating other token types on
Nexa. Sending and receiving tokens is just as simple as with NEX coins. These
can be used



All of this can be done for much less than a cent.

POW-SCALING

Nexa uses an extremely unique PoW algorithm that incentivises the market to
produce commodity hardware that accelerates node processing power, just like it
has produced commodity mining hardware like FPGAs and ASICs.



This will take Nexa’s capacity to 100,000TPS and over, providing enough capacity
for every person on the planet to have direct access to financial sovereignty.










WISE-CONTRACTS

Smart-contracts are great, but we can do better. EVM’s are very capable because
they are turing complete, but what they gain in flexibility they lose in
scalability.

Contracts on Nexa aren’t just smart, they are wise. A great definition for
‘wisdom’ is:



> knowing which knowledge is important and which isn't.



Nexa contracts provide an EVM-like level of functionality while using minimal
resources. This allows enormous capacity and low costs, even for complex DeFi
services.
