Initial Exchange Offering (IEO) essentially means the tokens will be released through a controlled central and authoritative collective of investors interested in the token marketplace. This is in lieu of allowing the public direct access to acquire a token.
Tokens become valuable of their own accord, based on supply, demand and the business case (in this case the SecureX Networks of vertical market domains) of the particular token. Please see the Road Map section at the bottom of the IEO page for the planned timing of the SECX SecureX IEO, and the related restrictions and processed for how to obtain tokens.
A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree).
By design, a blockchain is resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority. Although blockchain records are not unalterable, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been claimed with a blockchain.
The SecureX Blockchain, like all blockchains, uses a crypto token to pay the (very minuscule) transactional fee used for writing and authenticating each immutable record to the multi-distributed virtual chain. So it is important to create and fund said tokens. The SECX token is built upon the Ethereum Blockchain.
