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.

Bitcoin Diamond (BCD) is a fork of Bitcoin that occurs at the predetermined height of block 495,866 and therewith a new chain will be generated as the BCD. Bitcoin Diamond miners will begin creating blocks with a new proof-of-work algorithm, and will consecutively develop and enhance the protection for account transfer and privacy based on original features of BTC. This will cause a bifurcation of the Bitcoin blockchain. The original Bitcoin blockchain will continue unaltered, but a new branch of the blockchain will split off from the original chain. It shares the same transaction history with Bitcoin until it starts branching and coming into a unique block from which it diverges. As a result of this process, a new cryptocurrency was created which we call “Bitcoin Diamond”. Bitcoin Diamond coin could win over a lot of Bitcoin users with its faster transaction times, lower fees and easier access to new users. Bitcoin is a hugely popular coin but it can be quite difficult to use! Many critics of Bitcoin argue that the coin won’t be a valid replacement for normal money until users can make small purchases; quickly and easily. A network offering these features will also appeal to small businesses dealing in low priced, high-volume goods like coffee or fast food. However, in my opinion the price of Bitcoin Diamond will have to be more stable before it attracts any big-brand clients like Starbucks or McDonalds. One of the main safety features of blockchain technology is encryption. Private personal information is hidden using computer code. Some critics of Bitcoin think that not enough user information is encrypted. For example, all transactions and their amounts can be seen by anyone using the Bitcoin network. This can make tracing the real identities of users fairly easy for governments and other organizations. The team behind Bitcoin Diamond wanted to encrypt more user information. However, they have recently decided not to add more privacy features to BCD. They feel that governments will soon start passing laws that stop cryptocurrencies from hiding user data. In a statement published on Medium, the team noted Japan and Russia as examples of this trend. Bitcoin Diamond is processing much larger blocks than Bitcoin in the same amount of time. Larger blocks mean more transactions and a quicker average transaction time. Bitcoin Diamond makes it easy to mine BCD with less powerful computers. GPU mining allows more users to get involved in supporting the network and this can only be a good thing. Bitcoin is the world’s top cryptocurrency but it’s still quite difficult to use. Diamond coin’s high transaction speeds and low price could make it perfect for buying and selling small and inexpensive products like coffee or bus tickets.
