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.

The Raiden Network is an off-chain scaling solution, enabling near-instant, low-fee and scalable payments. It’s complementary to the Ethereum blockchain and works with any ERC20 compatible token. The Raiden project is work in progress. Its goal is to research state channel technology, define protocols and develop reference implementations. The introduction of payment channels, specifically the type first described by the Lightning Whitepaper (which introduced the Lightning Network), seeks to fix the scalability and congestion issues that currently plague blockchain technology. While the Lightning Network operates on the Bitcoin blockchain, Raiden introduces a comparable solution for the Ethereum network. There are several key features of the Raiden Network Token. Expedited transfer confirmations (<1 second ). Current transfers on the Ethereum blockchain can take a few seconds to minutes. Private transfers that are not viewable on the global ledger. Solve scalability issues so that Ethereum can create mass adoption, allowing Ethereum to become the peer-to-peer, global payments infrastructure with electronic cash that it was initially designed for. Low fee transactions. Micropayment capability that works in union with any ERC-20 token. The Raiden Network project is being developed by Germany’s Brainbot Technologies AG, a software company devoted to blockchain protocol development. Founded in the year 2000 by Heiko Hees, it currently has between 11 to 50 employees in offices among Berlin, Mainz, and Copenhagen. Also the founder of PediaPress, Hees has been a core developer of Ethereum since March 2014. Being a core developer for Ethereum, it is evident on how the founder sees the flaws in the current its present protocol with ways to improve it. Interestingly enough, the website does not include RDN as one of their main blockchain developments, which could be attributed to the difficulty of highlighting a wide variety of projects they are currently undertaking on one page. However, there are no updates on the status of the Raiden Network Project on either Twitter nor Medium since December 1st, 2017. Raiden can be used for a wide variety of applications and purposes such as Micropayments For Content Distribution, Decentralized M2M Markets, API Access and Fast Decentralized Exchanges.'
