Digix makes it possible to buy gold in an efficient manner via cryptocurrency by providing investors with a tokenized version of gold so you don’t have to physically own or store it. Digix has two cryptocurrencies, Digix Gold (DGX) and DigixDAO (DGD), each of which serves a key role in the structure. The company proudly gets 99.99 percent of its gold from LBMA-approved refiners, with zero percent from fractional reserves, delivering confidence. With Digix, investors can take advantage of the stability and value of gold as well as the ease of cryptocurrency. Digix essentially tokenizes gold within Ethereum. It takes advantage of the Distributed Ledger’s immutability, auditability, and transparency, applying all these benefits to the precious physical asset of gold. Additionally, Digix has developed multiple technologies, such as the DGX tokens and introduced a new Proof of Asset protocol (POA). A key feature of Digix is its physical gold bullion. By investing, users buy bullion from the LBMA refineries, including the Assay Certificates from refiners like Nadir Bullion, PAMP Suisse, Valcambi, and others. For security, Digix includes third-party auditing from Bureau Veritas. Every quarter, it audits each gold asset within the safehouse vaults. This auditor has been in business since 1828 and is a world leader in certification, inspection, and testing services. With such a long track record, investors should be able to trust Bureau Veritas for their auditing services. Finally, Digix involves recast, which means customers can take their DGX delivery at the partnering custodial vault. Digix incorporated in Singapore in December 2014 and the DGD crowdsale took place on March 30th, 2016. It was the first ever crowdsale and major Distributed Autonomous Organization hosted on the Ethereum network. The sale intended to run for 30 days but met its 5.5 million dollars hard cap in just 12 hours, selling 1.7 million DGD tokens and reserving 300,000 for the Digix team. Pledges who sent over 15,000 USD worth of Ether received a special badge which will allow them to submit proposals to the DigixDAO. For better or worse, when you see the word DAO, you might think of hacking. In July 2017, over 4000 DGD were indeed stolen due to a vulnerability in the crowdsale smart contract. The bug was eventually fixed and the tokens reimbursed to the 35 affected addresses. In January 2018, the vast majority of the cryptocurrency market crashed. DGD was the only coin in the top 100 to rise in value in that time. Perhaps this is an early indicator that people will seek gold as a safe haven during times of market uncertainty. The ICO price of DGD was about 3 dollars, but in 2018, DGD reached an all-time high of over 400 dollars. When Digix finally delivers the DGX tokens and the rewards to DGD participants start rolling in, we might see an even higher demand for DigixDAO. When DGX goes live, it will be available for purchase with Ether on the Digix marketplace.
Tezos is a coin created by a former Morgan Stanley analyst, Arthur Breitman. It is a smart contract platform which is does not involve in mining Tezos coins. It is a coin that promotes themselves on major ideas of self-amendment and on-chain governance. It is an Ethereum-like blockchain that hosts smart contracts. It allows the community to vote and improve its flaws. Any token holder may delegate their voting rights to others in the network. The coin uses a generic network shell which allow different transaction and consensus protocols that a blockchain needs to be compatible. The source code is implemented on OCaml which is a fast, flexible and functional programming language which should suit an ambitious project and its technical requirements. Tezos’ proof-of-stake consensus algorithm is different from the delegated proof-of-stake (dPOS) where they go by the name liquid proof-of-stake. This liquid proof-of-stake that Tezos uses focus in filling the gap between both security and decentralization but still being able to take advantage of the benefits that delegated proof-of-stake offers. The staking process in Tezos is called “baking”. In this blockchain, bakers who make deposits will be rewarded for signing up and publishing blocks. However, if a baker commits any bad behavior the deposits will be forfeited. Baking & Endorsing Baking is what Tezos refers to as the action of signing and publishing a new block in the chain. Bakers need at least 10,000 XTZ to qualify as a delegate, and having additional delegated stake increases their chances of being selected as a Baker or Endorser. At the beginning of each cycle (4096 blocks), the Bakers for each block are randomly selected and published. Bakers earn a block reward of 16 XTZ for baking a block. In addition to the Baker, 32 Endorsers are randomly selected to verify the last block that was baked. Endorsers receive 2 XTZ for each block they endorse. Block Rewards & Inflation Block rewards are funded by protocol defined inflation. Rewards are calibrated so that the number of XTZ tokens grows at roughly 5.5% per year. If 100% of Tezos tokens are delegated, the annualized yield will be 5.5%. Currently, 38% of Tezos tokens have been delegated, including the 10% owned by the Tezos Foundation, so the annualized yield is currently 14%. To ensure Bakers and Endorsers act honestly, they are required to post a security deposit for each block they Bake or Endorse. They forfeit this deposit in the event of malicious activity, such as double baking or double endorsing a block. In 2018, Tezos successfully launched their main network after delaying the launch due to corporate governance disputes. The Tezos foundation planned to transition the network to a mainnet, or a more complete version. The foundation has also raised $232 million in July 2017 to build the network and issue a new type of cryptocurrency to its backers in one of the largest- ever initial coin offerings. The founders have also made it clear in their blog that the network is using a new blockchain technology hence unexpected issues may still occur affecting the network.
