Kadena ICO Review

Kadena Review – Scalable Blockchain with Smarter Contracts (Public and Private)

Kadena is creating a public blockchain using a new consensus mechanism called Chainweb which offers a scaling solution for a Proof of Work consensus based chain system.


  • The blockchain space is moving at an incredibly rapid pace. With the constant development of second layers and dApps, the platforms suffer congestion and long transaction delays due to issues with scalability.
  • Moreover, efforts that seek to replace PoW with new consensus models like Proof-of-Stake (PoS) or integrate the protocol with off-chain networks and processes (payment channels, side chains) degrade the assurance, censorship resistance, and trustless nature of the original PoW design.
  • Therefore the space is currently at a state of uncertainty in terms of where to balance mass volume usage (necessary for mass public adoption) and security.


  • To resolve these current limitations of PoW we present Chainweb, a parallel chain PoW architecture that combines hundreds or  thousands of individually mined peer chains into a single network, capable of achieving throughput in excess of 10,000 transactions per second.
  • Unlike other platforms proposed form of consensus, Chainweb’s parallel network model maintains security without using side chains or only using specific part of a blockchain to process a large number of transactions. Kadena’s tests found an extremely high level of security with their proposal, which intends to produce roughly 1,000 different chains eventually for public use.
  • With multiple parallel chains working simultaneously, if specific chains are congested by a dApp, a different chain can be utilized to conduct an ICO.
  • Kadena’s solution gives every chain the primary chain functions, thus not a side-chain approach to solving scalability.

Main Features 

Chainweb – Kadena’s “massively-parallelized public blockchain platform” will utilize the Chainweb Protocol as its consensus mechanism.

Chainweb is a Proof-of-Work Parallel-Chain Architecture for Massive Throughput.

Multiple chains integrate their Merkle roots (the Merkle root is the hash of all the hashes of all the transactions in the block) with each other, ensuring that while each individual chain acts as a unique blockchain, it can still share information and reach consensus with other chains.

Every single chain will produce Kadena’s tokens, and Chainweb’s protocol will ensure that the same coin cannot exist on two chains at the same time.

Chainweb will use a Simple Payment Verification (SPV) to delete coins that are sent to another chain before being created on the receiving chain.

This process is a trustless destructive cross-chain coin transfer through SPV which occurs at the smart contract level.

Kandena ICO

Step by Step guide on the trustless destructive cross-chain transfer process:

If Dan wants to move his coins from Chain A to Chain B, he would take the following steps:

  • Step 1: Dan, who’s coins are currently on Chain A, would specify which account he is deleting the coins on & the amount of coins to be destroyed.
  • Step 2 : Dan would then specify that he is sending his coins to Chain B, and also include the account on Chain B to receive those coins.
  • Step 3 : Upon completion of the transaction, Dan would take that Merkle Proof to the “Creation Chain” to prove that he has indeed deleted his coins. (This step is done at the smart contract level)
  • Step 4: The smart contract would then run SPV, verify that the actions in step 1 and 2 have occurred, then distributes the coins to the specified account.
  • Step 5 : The “Delete Coin transaction ID” is then consumed to prevent being used twice.

Additional Resources:

Kadena compiled TG Q&A with Co-Founder Will Martino & other team members.

Q: How do the miners guarantee the safety of each chain with so many parallel block chains?

Q: Are users assigned a chain to be on, or do they select their own chain providers? Will there be any reason that particular chains might compete for users on their own chain?

Q: What is to prevent, for example, everyone from choosing the same chain?

Q: When are all the parallel chains created?

Q: So all the thousands of parallel chains are created at the genesis? And then to add capacity there is a hard fork which adds new chains?

Q: Is Kadena similar to ICON?

Q: Can only PoW consensus mechanism join the braid?

Q: Can coins that already do PoW join the braid?

Q: Does Kadena see it self as an interoperable solution?

Q: Is this a scalable solution for PoW?

Q: Is the scalability of ChainWeb theoretically infinite?

Q: How is PoW not about economic power?

Q: What is the vesting schedule for Team and Advisors token?

Q: Is vesting for Team and Advisors coded in the smart contract?

Q: Was your smart contract audited by an independent cybersecurity company?

Q: Is achieving 100k tps actually feasible?

Q: Regarding connection between your public blockchain and private blockchains. Is there any connection? Do they use the same token? Let's say there is 100M tokens in circulation available for people to buy. If some company wants to setup a private blockchain with you, do they use a set of these 100M tokens or something totally different?

Q: Why isn’t Pact turing complete?

Q: Do you think lightning network makes what Chainweb is obsolete?

Q: Which is better, lightning network or Chainweb?

Q: How is Kadena better than Credits? Credits claims it does above 230k Transactions per second.

Q: Could the Chainweb protocol scale beyond that level (230k transactions per second)?
