Kadena is a layer 1 hybrid Proof-of-Work ‘parallelized’ blockchain solution inspired by #Bitcoin
#Kadena uses a smart contract language named ‘Pact’ and a ‘braided chain’ fixed graph PoW model they call ‘Chainweb’.
First, let’s dive in to Chainweb.
Though Bitcoin created the world’s first public trustless network
it’s limitations didn’t take long to spot:
-slow transaction times (bottlenecking)
-high transaction fees
-enormous energy consumption
-unable to scale effectively
-51 percent attack
PoW single-chain consensus models are considered 1st generation blockchain technology.
Like the first phone, an evolutionary improvement was needed on the ground-breaking technology built by Satoshi.
Kadena & their founders saw the potential in Proof of Work’s model, but with a big upgrade: Chainweb.
In Chainweb, rather than one linear chain
- Picture chains that are “braided” together paralleled to create a single ‘super’ chain.
The sum becomes greater than its parts!
Using fixed graph theory makes $KDA different than DAG-based models to facilitate information on its network.
Currently $KDA is operating 20 chains , with the ability to increase as needed.
**(Kadena’s Kuro permissioned network reached a peak capacity of 480,000 TPS)**
Chainweb is currently capable of 10,000 transactions a second
vs a meager 7 of Bitcoin. (For reference)
You maintain the vision of what Satoshi built, just with increased throughput , scalability & more.
While other consensus models that are ‘deterministic’ may offer just as many benefits (though trust based)
There is no limit on the number of participants with PoW - it’s also trust less in nature
Unlimited miners become possible Due to its unique structure (more on this below)
The 2 distinct features of Chainweb:
- cross chain transfers via on chain SPV smart contracts
-parallel chain binding @ the hashing level via a peer chain merkle root inclusion
In simpler terms:
Data can be verified at scale by users and miners with accuracy in a structured manner
At a infinitely higher throughput and lower energy output than #btc
*Side note: No parachains or side chains are needed like $DOT or other blockchains use*
How?
Competition of mining is distributed across many chains
Lowering the per-chain hash rate significantly
And significantly harder to 51 percent attack or fork

NEXT:
PACT - the smart contract language (SCL) of #Kadena
The bridge that ties the ecosystem together on this hybrid blockchain.
According to the white paper:
Pact was designed to be a better solution for implementing high-value business workflows on a blockchain
Looking to improve on the shortcomings of #ethereum solidity SCL, Pact follows the philosophy of
“readable by humans, verifiable by computers”
Pact was intentionally designed to be ‘Turing-incomplete’
Making recursion & unbound looping impossible in its language.
Ease of use and functionality by developers and non developers alike makes this SCL very EASY to understand & smart contract upgradability becomes easy.
Pact’s specialty:
formal verification
What makes this important?
This allows code to be transformed into a mathematical model that can prove properties of that model can satisfy correct behavior over ALL possible inputs and program states
Pact also offers:
-built in governance mechanisms
-native oracle support
-REST API’s
-data integrations
-easy to understand language for devs & non devs
-error messages
-multi signature
- contract upgradability
Making Pact a potential global standard for Smart Contracts
Founders
Who are they?
Meet Stuart Popejoy & Will Martino
Prior to Kadena, the dynamic duo led JP Morgan’s blockchain for excellence.
While at the helm, they built the company’s first blockchain called Juno, which has become their JPM coin.
Also interesting to mention:
Will Martino was the former tech lead at the Securities & Exchange Commission Cryptocurrency steering committee 🇺🇸
In their respective positions, Stuart and Will also vetted many too blockchain projects while at JP Morgan.
They noticed a distinct problem:
A blockchain that could handle the performance and security needed for global financial institutions.
