IOST is building an ultra-high TPS blockchain infrastructure to meet the security and scalability needs of a decentralized economy. Led by a team of proven founders and backed by $40 million from world-class investors, including Sequoia and Matrix, IOST aims to be the underlying architecture for the future of online services. The powerful consensus algorithm “Proof-of-Believability” enables next-gen transaction throughput speeds while ensuring nodes stay compliant, using factors including IOST token balance, reputation-based token balance, network contributions and user behaviors. A faster grade Byzantine Fault Tolerance mechanism, microstate blocks, Atomic Commit protocol and a dynamic sharding protocol (Efficient Distributed Sharding) all ensure transactions are safeguarded, consistent and lightning fast while reducing storage, configuration costs and processing power for validators. Anyone is able to participate in every layer of our system, from using services on our blockchain to running a node and validating transactions. Our rules and code are open for all to see and no preconditions will limit participation. IOST aims to fundamentally disrupt previous methods of business by creating a self-operated, trustless network that maximizes network value for all parties. The project places great emphasis on decentralized and secure ways of storing information. It also provides for Dapps and smart contracts, and anyone who is familiar with blockchain technology knows just how integral these two concepts have become. Adhering to the quintessential egalitarian values of blockchain technology, IOST is creating a censorship-resistant and trustless network that is open to all, using blockchain technology to cut out middlemen and maximize network value for all parties. Terrace Wang, Kimmy Zhong, and Ray Xiao, who are extremely brilliant, have co-founded the project. In addition to these original three, the project has 12 employees and 4 advisors. It is also worth noting that Ryan Bubiski, a co-founder of CodeAcademy and a winner of Times Most Influential People award plays a major role in the advisory board of the project. The team has partnered with about sixteen blockchain and cryptocurrency oriented companies such as Sequoia, Nirvana Capital, and DFund. The project, therefore, has strong investors.'
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.
