Shift is cryptocurrency that was launched in August 2015 based on Ethereum by a group of cryptocurrency enthusiast. Shift Storage Cluster - The default state of the IPFS infrastructure is represented as a globally shared network. This can lead to problems when it comes to verifying data integrity, availability, and custom implementation details such as earning token rewards for running a storage node. For this reason, Shift runs a private swarm. The storage nodes use a custom swarm key to ensure that they can only talk to other nodes using the same key. This also prevents Shift nodes being used to host and deliver content that was added outside of the Shift network which should improve reliability and performance. In order to store data permanently, IPFS implements a concept called pinning. Pinning content means that the content will be available permanently (or until it is unpinned). By default the pinning only applies to a single peer that it is pinned to, but that means if that machine goes offline, the content can be lost. The way around this is by using an IPFS cluster: a subnet (or private net) running the IPFS daemon, containing only Shift peers. The Shift cluster runs as a wrapper around the IPFS daemon. It allows the end user to connect a group of IPFS nodes together so that content can be stored and replicated within the group. The cluster elects a leader to be in charge of keeping track of which content is available in which locations. Shift is meant to disrupt the web hosting industry. The company has created Phantom which is a decentralized app to host websites. It does so through the Shift IPFS rather than the normal way a website is hosted. By using this ‘killer dApp’, the company is of the opinion that a business gets a chance of succeeding in the current competitive world. Because Shift is an open-source platform, developers of dApps are free to use the company’s script. This is made even easier by the fact that Shift Company has used Javascript which is popular language among dApp developers. According to the company, every dApp created using the Shift script can access the IPFS cluster to store data. This will be made possible by the use of a P2P hypermedia distribution protocol, an interplanetary file system which the company created. Even though the Shift has been around since 2015, the team only released the whitepaper on March the 5th 2018. The whitepaper is a bit technical but well detailed. Remember that the crypto is built with dApps developers in mind. It might not be a very good investment opportunity for a person who doesn’t understand dApps and Javascript. But at the end of the day, it is a volatile crypto which is one of the most important features to look for as a trader.
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.
