SOVRIN [Token Profile]

One Portable Digital Identity for the Global Netizen

In the competition to manage our future digital identities, the blockchain has emerged as a clear leader on the technology front. The Sovrin Foundation—a creator of portable digital identities for individuals, organizations and things—is positioning to be the global public utility of digital identities on the distributed digital ledger. The nonprofit organization has attracted some technology giants to help steward its digital identity network.

The weaknesses of the current centrally managed digital identity system have been well documented.

Of foremost concern are the selling, hacking and manipulation for marketing purposes of information without informed consent. The rapid growth in the number of individual digital identities is increasing susceptibility to these privacy invasions. The average number of online accounts per internet user is expected to double from 100 to 200 by 2020. On average, these netizens use 12 different passwords.

Full Stewardship Ahead

The self-sovereign identity is a lifetime portable identity designed to replace the average internet user’s multiple siloed identities dispersed in centrally controlled data repositories around the globe. Sovrin replaces the many central authorities that handle digital identities for their respective sites with a global public utility that assigns one sovereign digital identity to each individual. This cryptographically secure digital identity is created by adding an identity layer to the Internet. Unlike centrally managed identities, owners have full stewardship of their digital identities, including permissions.

A Portable Self-Sovereign Identity

The competition to be the digital identity platform of the internet is young. Only with the arrival of the blockchain and related protocols did a fully viable alternative identity verification platform appear. The Sovrin service has benefitted from the Verifiable Claims Working Group’s initiative to standardize identification in the banking, health, government, education and other areas.

The self-sovereign identity platform replaces centralized roots of trust such as certificates of authorities, which are time-consuming and costly to use, with a consensus algorithm that distributes information across many machines in a decentralized network. A cryptographic record of immutable transactions is then formed.

Sovrin has further benefited from W3Cs introduction of decentralized identifiers (DIDs), which allow the creation of cryptographically verified identifiers under the owner’s control. The DID and related information are stored on the blockchain with a public key accessible by the owner’s private key.


The Sovrin token will be used as an exchange of value in the protection of privacy by credential issuers, owners, and verifers. The token can be used in the Sovrin global marketplace to digitize credentials, as well as for digital credential insurance and permissioned first party data (direct from the customer).


Token Sale: June–August, 2018 (To be announced)


The Sovrin Foundation is a hub of development activity for global digital identity services. Sovrin Foundation Stewards are developing and will ensure interoperability of the open source decentralized digital identity network. IBM, the leader in Blockchain enterprise solutions, became a founding steward in April 2018.

Solana [Profile] – Token Information

High Performance Ledger Scales With the Passage of Time

The quest for a scalable blockchain protocol that does not degrade performance in other areas of a blockchain network continues. Many developers have met the call for a higher speed and capacity consensus algorithm to verify digital transactions on the blockchain, but few solutions are flawless.

While all agree that the proof of work (PoW) protocol is abysmally slow and consumes a lot of electricity, not all agree that the preferred replacement, proof of stake (PoS), is the best solution.
A new entrant, Solana, believes the complete solution to blockchain scalability requires three verification protocols.

The Proof of History Protocol

Solana has introduced the proof of history (PoH) protocol to verify transactions by cryptographically encoding the chronological sequence of hashes—the unique digital identifier of a transaction. The proof of stake consensus mechanism is then used to confirm the PoH sequence and vote on the next PoH generator node. Like under normal PoS conditions, those who validate nodes which do not form the consensus are punished. The PoH, together with a proof of replication (PoRep) protocol—which provides fast streaming verifications of time in the proof of history sequence—prevent double spending, spam and fraud.

THE solana transaction flow

How does Solana plan to outpace Google, Facebook and NASDAQ on transaction capacity?

Solana has borrowed technology from ancient mariners to build its high throughput blockchain. The analogy of a water clock is aptly used to explain the proof of history (PoH) protocol. In the same way the ancient Greeks recorded the passage of time by marking the rising water level on a ship, the sequential output of a hashed Blockchain state and count can be cryptographically recorded to reliably signify the order in which the hashes were generated.

the solana architecture 

The solution avoids the popular sharding approach—partitioning a database into smaller chunks and processing them in parallel. The Solana approach allows the data structure to be sliced and verified via parallel processing that is limited only by the capacity of the computer. Nodes can be added without slowing down the transaction processing speed or sacrificing security, whereas sharding requires increasing the number of validators at each node, and thus introducing security risk. To avoid the PoS challenge of verifiers approving every hash, an invalid hash is randomly injected and voters for that hash eliminated.

Meanwhile, bandwidth is minimized by a “ledger replication architecture,” allowing the Solana blockchain to scale to tens of thousands of nodes while maintaining its subsecond finality times.

The Performance Difference?

The Nasdaq network processes about 5,000 transactions a second. The Solana blockchain is initially scaling to 710,000 tps and 10,000 nodes. With these network efficiencies, transaction costs will fall to $0.000001. As more applications use the Solana blockchain, Solana expects to expand to 28.4m TPS on a 40 gigabit network and is confident it can meet this future capacity demand.

The Solana team is not likely to buckle under the competition to become the highest performing blockchain. Solana’s executive management and four of its principal engineers were in key positions in the evolution to higher speed mobile networks at Qualcomm, as well as other mobile and technology companies.

Token Utility

The Solana exchange will facilitate the trading of different cryptocurrencies across different blockchains called atomic cross chain transactions, as well as tradable swaps. Solana will be attractive to applications with large data processing needs, such as marketing data collection, decentralized exchanges and payments.. The platform recently partnered with Helium, developer of the Helium Decentralised Machine Network, a blockchain that makes it easy to create IoT ecosystems of networked devices.

Liquidity Network (LQD) [Profile] – Token Information

Swift Payments Sidechain Avoids Congestion and High Fees

Scalability and high transaction fees remain two of the major obstacles to mass adoption of the blockchain. One of the proposed solutions is processing transactions off chain. One off-chain solution, the Liquidity Network, has merited the endorsement of Ethereum network developer Vitalik Buterin. The Liquidity Network is an off-chain payment system designed to transfer micropayments in Ethereum. Payments are rebalanced off-chain to avoid costly on-chain refunding of transaction channels. The “trustless PayPal” eliminates blockchain congestion and miner front running while delivering speedier payment transactions.

HOW DOES REVIVE Scale the Blockchain?

The brain of the Liquidity Network is the work of two computer engineering students at ETH Zurich focused on removing frictions in Blockchain networks. Arthur Gervais and Rami Khalil combined their expertise to develop REVIVE, a transaction processing algorithm with high throughput that solves network congestion. A major function of the Blockchain is support for direct peer-to-peer transaction channels, which significantly reduces costs by eliminating central transaction intermediaries. However, channels must be closed and refunded to clear them for new transactions, a costly on-chain transaction.

Revive Gas Costs

REVIVE allows users to maintain multiple channels with different entities by providing a mechanism to balance the funding of channels. The side chain balancing eliminates the need to go on-chain to clear channels, and thus improves the scalability of the network. Transaction scalability is increased by eliminating costly and time consuming on-chain channel management while users are incentivized to use the lowest cost channels. The off-chain transactions can be performed at trading speeds comparable to that of centralized exchanges.

Fast Blockchain Payments for Everyone

The Liquidity Hub allows any user of any payment hub to make fast peer-to-peer payments. The off-chain Liquidity Exchange does not require tokens as collateral or hold assets. This way the non-custodial system is able to avoid congestion and high fees. Liquidity envisions its ecosystem being used for digital payments, diverse Blockchain applications ranging from gaming to rental services, and in IoT networks. Liquidity plans to operate an open source ecosystem for fast, secure payment processing in which others can operate Liquidity Network Hubs.

Token Utility

The LQD token is not a network access coin but rather used to buy premium services such as faster transaction processing and channel monitoring. Otherwise, regular users do not pay a fee and the ecosystem is free to join.

Harmony [Profile] – Token Information

The 5G Blockchain Revving up to Host Next Generation IoT, Augmented Reality and Robotics

Harmony aims to provide the fastest on ramp to the blockchain world. The competition to be the fastest blockchain is stiff, and the ranking changes monthly, but so far Harmony’s team of accomplished technologists is out in front.

The ambition of the executive and advisory team, incidentally steeped in former Googlers, is to produce a Google-scale blockchain by accelerating the speed of the decentralized marketplace by 1,000 times.
Google’s UDP, which handles the equivalent of 7 percent of Internet traffic with low latency, will help accelerate the souped up blockchain. The Harmony blockchain aims to process 10 million transactions per second with 100-millisecond latency. The transaction fee will be 0.1% or lower.

An On Ramp to 5G Speeds

The Blockchain will serve as the nexus of the Internet of Things, be it connected supply chains, homes or cars. The challenge is, services are being designed for this interconnected world on a 5G network while the current blockchain operates on a 3G/4G network. The race is on to build the fastest Blockchain but, so far, few Blockchains have passed the 5G threshold. Harmony cites Dfinity, Algorand, and Zilliqa as competitors, although their reported specs fall short of those of Harmony.

The OmniLedger Sharding Difference 

A 10x faster network than Bitcoin or Ethereum will be required for the blockchain to host next generation supply chains, energy grids, financial trading and autonomous robots, estimates Harmony. To deliver these performance improvements, Harmony is performing a complete overhaul of the blockchain. Upgrades on the transport network include replacing TCP/IP with the Google UDP and deploying 5G mobile communication protocols. On the consensus protocol, high scalability is achieved using the sharding technology of the OmniLedger. The system is scalable to 100,000 nodes. In systems tooling, various innovations are being applied to provide parallel transaction processing, memory optimization, and faster program execution.

More Technical Substance, Less Hype

Harmony appears to barely have a footprint in the real world—its website and social media are sparse but considering the technical bench strength behind the project, it is not likely to be dismissed as more ICO hype. On the contrary, its detailed technical white paper reveals its grand design involves extensively reengineering the blockchain with next generation solutions, partially outlined above.

CEO Stephen Tse, holder of a PhD in cryptographic protocol, has lent his engineering expertise to Microsoft, Google and Apple, to which he sold mobile search company Spotsetter. CFO Alok Kothari is an award-winning machine learning expert who taught Apple’s Siri natural language processing. Tse and his team members have developed expertise in protocols and compilers, AI, deep learning, machine learning, and the blockchain at technology stalwarts including Microsoft, Google, IBM and Apple.

Advisory board members have headed major Google research initiatives, and include a former Google global creative director, head of mobile engineering, and marketing and strategy lead for Google Play. The team also represents an impressive breadth of technology startup experience.

Token Utility

The Harmony token will be the currency of a marketplace for the service and payments of IoT devices. Harmony also envisions its blockchain supporting incentivized games, augmented reality, autonomous cars, and swarm robots applications.

Blockchain Allows Users to Control and Monetize Their Data App-by-App

Two thirds of Americans believe that Facebook sells their data, according to market research firm Qriously. Although their impressions are, in fact, incorrect, the survey reveals the high level of consumer concern over inappropriate data usage by marketers. Third party data brokers are responsible for the sale of most consumer data, and in the age of big data, their data collection methods are not only becoming more powerful but also more surreptitious. Mobile apps, screen savers and antivirus programs are helping big data collectors aggregate personal information without the owner’s permission.

A new blockchain company is responding to the collective angst over data usurpers and giving control of personal data back to consumers. South Korea-based AIRBLOC is acting as the nexus between advertisers seeking data for targeted marketing campaigns and individuals willing to sell their data. Individuals can now control and monetize their data rather than a large centralized data aggregator profiting from it, while advertisers are able to more precisely target the data they collect to their target markets and thus improve their ROIs.

Democratizing Data

AIRBLOC’s ubiquitous DAuth protocol is already disrupting the advertising data aggregation model in South Korea. Marketing data is big business for brokers. Some companies spend as much as 60 percent of their budgets on data acquisition for use in marketing and business intelligence. However, the majority of data aggregation is permission-less, meaning it is gathered and used without the consent of the owner. Data brokers, then, not the data owners get paid for selling the data to the marketing industry.

THE AIRBLOC SDK gives data control back to individuals by attaching its data matching engine to mobile data apps. Applications with an existing user base can allow those users to access the AIRBLOC network. The app user then decides whether or not to share data and what data to share on an app-by-app basis. Importantly, they can track the use of the data. Users have other options to earn rewards. An app user, for example, could approve receiving targeted advertisements from AIRBLOC advertisers but refuse permission to use her personal data.

Security is another pain point following the 2017 data hacks of Experian and Alteryx, which exposed the personal data of over a quarter billion consumers. AIRBLOC brings new levels of security and privacy to personal data management by encrypting and storing data on the secure blockchain.

Data Priced for Every Marketing Budget

The AIRBLOC decentralized personal data protocol has strong marketing currents behind it. The company is owned by Korean data analytics giant ab180, whose clients include over 300 large Korean companies. Over 40 million mobile devices, or two thirds of Korean mobile devices are already part of the AIRBLOC system.

But not only big data marketers benefit. Advertisers can more precisely target data acquisition, which is priced according to supply and demand, in micro-targeted advertising campaigns. The lower costs of aggregating distributed data on the blockchain makes it feasible for small applications and even individuals to sell their data. Small- and medium-sized advertisers previously lacking data access due to the high cost benefit from the ability to buy data at an affordable price.

A running shoe company, for example, could collect direct data from an e-commerce app by asking consumers searching for running shoes about their buying intentions. The shoe marketer could also collect indirect data from users who have given data access permission on running shoe purchases, and apply further filters such as on sex, region, shoe color, and so on.

Token Utility

In exchange for selling data to advertisers, data owners can be paid in two ways. They can receive the AIRBLOC ECR-20 compliant token, ABL, or an AIRBLOC Reward (AIR), convertible 1-to-1 into ABL. AIR is also used to rate the good citizenship of users. Contribution level is rated by the number of AIR tokens held. Total AIR, total data contributed and time influence the Participation rating. Good citizens can rate the data reliability mining—the quality of data provided—of others and earn more AIR rewards.

Following the successful ICO funding, AIRBLOC is focused on developing its ecosystem. Ab180 is using 10 percent of the tokens to entice data providers and data users to contribute data based on in demand data from campaigns. The AIRBLOC SDK is already being tested on the majority of South Korean mobile apps. The full release of the AIRBLOC SDK and AIRBLOC data marketplace will take place in the second quarter of 2019.
