4MB Blocks

IOC block size allows for up to four times the capacity of Bitcoin blocks. It is also capable of carrying 1MB of AES 256 Encrypted Data storage  per block. Specialized for NFT native storage

AES 256 Encrypted Messaging

The IOC blockchain enables users to build apps and natively message any enabled alias in iOC by creating encrypted tunnels for private messaging. This features extends to IOT devices 

Dions Virtual Machine  (In Development)

DVM it's IOC's Solidity Compatible Virtual Machine. DVM will process all of the Bytecode via our DIONS payload. Enabling Ethereum compatible  smart contracts

AES 256 Encrypted Data Storage 

Our unique DNS system allows for the creation of private and public aliases enabling sending and receiving of IOC but also to upload, attach, and transfer up to a 1MB Arbitrary Data

Proof Of Stake Cipher

POS Cipher is a state-of-the-art secure consensus ensuring fairness for all stakers.  Stakers get a  1.5 IOC reward for every confirmed block. This is based on weight, time, and proximity to TX node 

16 Second Block Confirmation

Under normal transaction load, blocks confirm at 60-second intervals. As transactions pick up, blocks can confirm as quickly as 16 seconds

Abstract Linear Background
Proof Of Stake Blockchain
Since 2014

I/O Coin (IOC) genesis block was mined on July 24th, 2014. IOC is a cryptocurrency that powers a privacy based blockchain ecosystem. IOC was launched via POW X11 (video card resistant) algorithm.


The difficult mining period lasted for 2 weeks with an initial 22 Million max retarget cap. This in order to properly and fairly distribute 16M coins before switching over to our own unique flavor of Proof of Stake Cipher to secure our blockchain. 




Updates and Development Roadmap

Beyond Bitcoin and Ethereum: Uncovering the Potential of I/O Coin

Solidity Compatible Smart Contracts being enabled to work on IOC via Dions virtual machine. Along with DeMix dapp 

Decentralized I/O Exchange will facilitate token swaps via our solidity compatible Smart Contracts and IOCoin

3. Chameleon

Will address interoperability, scalability, faulty smart contracts and facilitate a very high transactional throughput for global usage. Introducing a new technology via Entropy Based Graph Ledger

4. NightHawk

Will fortify the coins privacy by encrypting user balances and adding ring signatures to all transactions. Ring sigs will be default to 5 with up to 30 rings. Balances will only be known by the sender and receiver.

Private Identity Storage

The IOCoin Blockchain enables users to acquire unique DNS identities. Identities have two states: public and private.Private identities can be used as means of anchoring files and are transferable. Private identities can also be made public in order to send IOC without the need of the long hex address.  Aliases also serve as names for file storage. 

Encrypted Data Communications

IOCoin holders can enjoy the comfort of private communications. The private communications are fully decentralized encrypted messages. These messages are never stored in a central database or server. Messages are encrypted via AES256 and exchanged via public identities after officially formulating key exchanges which enable encrypted tunnels of communication between the parties.

Encrypted Data Storage & Transfer

Any user holding a private address can upload a 1MB file which the user could attach to a private identity indefinitely. A private DION must be updated every 220,000 blocks. If the user fails to update his or her private identity, the user can at any time retrieve the file using his or her private keys. All files are compressed and encrypted via AES256 encryption. All files can be transferable between users while in a private state through encrypted handshakes. 

Dions Pay "Shade" Private Send

IOCoin holders can send private payments. These payments are shade DION addresses which make it less intrusive on a user’s single public address. Users are also shielded by our DNS protocol from revealing the public address on blockchain to a simple human readable alias.
