What Is OMG Network and How Does It Work?
OMG Network is a subsidiary of Omise, a well-established Thailand-based payment solutions company. Upon its launch in 2017, OMG was originally called OmiseGO. The OMG Network is able to process thousands of transactions per second, and can reduce the costs of operating on Ethereum by one-third.
OMG Network is a scaling solution that increases the transactional throughput of Ethereum. The OMG Network creates a value transfer layer on top of Ethereum that bundles together Ethereum transactions and validates them through a speed-optimized child chain before sending them back to the Ethereum blockchain for confirmation. The OMG Network is able to process thousands of transactions per second, and can reduce the costs of operating on Ethereum by one third. The OMG Network’s native OMG token can be used to pay for transaction fees and for staking when the platform launches its proof of stake protocol.
Initially called OmiseGO upon launch in 2017, OMG Network is a subsidiary of Omise, a well-established, Thailand-based payment solutions company. OMG Network’s tech is based on Plasma, a framework conceived by Ethereum creator Vitalik Buterin and blockchain technologist Joseph Poon. OMG Network was among the first ‘layer two’ scaling solutions proposed for Ethereum, which are critically important secondary tech integrations that increase a network’s transactional throughput.
Plasma is a framework for moving bulk transactions off of the Ethereum blockchain onto “child chains” — blockchains that exist alongside the Ethereum blockchain connected to the main network. Plasma childchains are optimized to speed up transaction processing, before data is returned for final validation on the Ethereum motherchain. The OMG Network is able to process thousands of transactions per second, and can reduce the costs of operating on Ethereum by one third.
OMG network’s native token, OMG, was minted to raise funds for the development of the project through an initial coin offering (ICO) in 2017. Shortly after, OMG was airdropped to the Ethereum community—the first instance of such an airdrop on Ethereum. OMG is now used for paying transaction fees, as a staking mechanism once OMG launches Proof-of-Stake, and for network governance participation.
Layer Two Scaling on Ethereum
Layer two scaling solutions are an essential part of Ethereum development, so let’s review before we get into the mechanics of the OMG Network. Scalability in this context refers to a blockchain’s ability to process a high volume of transactions both quickly and cheaply. While centralized databases like Visa are capable of processing tens of thousands of transactions per second, Bitcoin and Ethereum are only able to handle around five and 14 transactions per second respectively. This is due to the intensive mechanisms for data verification and consensus on blockchain networks that are required to maintain decentralization and security.
Without implementing successful scaling mechanisms, Bitcoin and Ethereum would be technically unable to achieve the high-volume utility of global transaction layers like Visa. In fact, both Bitcoin and Ethereum have already encountered congestion issues, backlogs, and periods of increased fees on multiple occasions. Scaling has been a subject of intense scrutiny and development in the blockchain industry.
There are upwards of fifty projects building scaling solutions for Ethereum that champion two primary methodologies. State channels like Raiden and Celer Network create Ethereum-adjacent blockchains that transport Ethereum data ‘off-chain’ for transactions and return back generalized ‘state’ data reports. Side chains like OMG Network use the Plasma method of layering a centralized, but transactionally efficient mirror chain on top of the Ethereum network, where bulk transactions are executed before being sent back to Ethereum for a final validation.
How Does OMG Work?
The OMG Network protocol utilizes an update of Plasma — called More Viable Plasma or MoreVP — to significantly increase transaction throughput. More specifically, the OMG Network bundles transactions together, compresses them into one transaction, and verifies them on the OMG child chain. The child chain then returns confirmed transactions to Ethereum for confirmation on the blockchain. This bundling technique enables the OMG Network to process thousands of transactions per second. Transactions cost one third of what they would cost on Ethereum because gas fees are paid on the bundled, compressed transaction instead of each individual transaction.
The OMG Network child chain is controlled by a single block producing node called an Operator, which validates transactions before forwarding them to Ethereum. While Ethereum has upwards of 8000 nodes, OMG Network has only one. Proponents of state channels argue that this centralized mechanism compromises the distributed ethos of blockchain. OMG Network, however, decentralizes security through a network of computers called “watchers,” which monitor the Operator and the network for suspicious activity. Anyone can become a watcher.
Though the child chain is operated by a centralized block producing node, the OMG Network’s security is decentralized because Ethereum’s network of nodes maintains finality on transaction approval. Likewise, the network of watchers which monitors the network for security threats is also decentralized, providing the security and vigilance inherent in a decentralized network. Additionally, the child chain is non-custodial, which means that users’ funds never leave the Ethereum network. As a result, users will always be able to recover their funds, even if the OMG Network child chain goes offline — a feature also known as trustlessness.
Let’s run through a traditional Ethereum transaction, and then a transaction that is routed through OMG Network.
In a typical Ethereum transaction:
You use your wallet to initiate a transfer of assets from your wallet address to a different wallet address or smart contract address
Then, Ethereum assigns a transaction hash — a transaction identification number — to your transaction.
The transaction will subsequently be broadcast to the Ethereum network and put in a pool with other transactions.
Miners will eventually select your transaction, verify it, and include it in a block of the blockchain, completing your transaction.
When a transaction is routed through OMG Network:
You first deposit ERC-20 tokens or ether into your Ethereum address.
You initiate a transaction to deposit your assets into an Ethereum smart contract.
Both the Ethereum and OMG Networks record this transaction, and the Operator creates a representation of your assets on the OMG Network child chain.
You can then use your wallet to initiate a transfer of assets from your wallet address to a different wallet address.
The Operator takes your transaction and bundles it into a group with other transactions and records them in a block.
The Operator sends a transaction hash of all the individual transaction hashes in the block to Ethereum for validation, completing the transaction.
When you’re done transacting on the OMG Network child chain, you can initiate another transaction to withdraw your funds from the Ethereum smart contract.
OMG Network is ERC-20 interoperable, and thus decentralized applications (dApps), wallets, custodians, and exchanges can all take advantage of its scalability benefits. For example, the OMG Network integrated with the Bitfinex exchange to allow traders to transfer, deposit, and withdraw its native stablecoin tether (USDT) via OMG. Additionally, the OMG Network provides enterprise clients with private versions of the network for use cases such as loyalty points programs. It has also proposed that the platform could be used for central bank digital currencies. A highly anticipated and influential project upon announcement, OMG Network has now proven the feasibility of layer two scaling solutions, alongside the functionality of Plasma and Ethereum side chains.
