Tezos is a self-healing blockchain that upgrades itself over time. Stakeholders can vote on amendments to the protocol, not limited to any element of consensus on the proposal. Just like Ethereum, Tezos supports smart contracts and provides a platform on which others can build decentralized applications (Dapps).
What is Tezos?
Tezos is a coin created by a former Morgan Stanley analyst, Arthur Breitman. It is a smart contract platform which does not involve mining Tezos coins. It is a coin that promotes 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 allows different transaction and consensus protocols that a blockchain needs to be compatible.
It is characterized by supporting smart contracts and owning a smart contract language created by itself. For the first time, it proposes a code self-made transaction and network consensus mechanism through mathematical proof to solve the current thorny network upgrade and fork problem. The white paper of the project was released in the same period of Ethereum, and the ICO started three years later after the release of the test code. A total of 65,000 BTC and 360,000 ETH were raised, which was the largest ICO project at that time. Later, due to the conflict between the management team and the foundation, it encountered setbacks, but still received strong support from the community. Bezos BetaNet was launched on the last day of Q2, 2018. All transfer records and assets on BetaNet will be carried to the mainnet later, which means that transactions on BetaNet are valid for a long time.
What is the Tezos' DPOS algorithm?
In order to improve TPS and scalability, Tezos uses the same DPOS algorithm as EOS.
On Tezos, validators are also called Bakers. There is no limit to the number of bakers. The condition for becoming a baker is to stake a certain amount of Tezos token (XTZ) to participate in the consensus. The mortgaged tokens are calculated in units of "rolls", each of which represents 10,000 XTZ. Each roll of mortgaged XTZ has a unique id, and this id will play an important role in the selection of validators in the consensus process. Blocks on Tezos are calculated in "cycles", and there are 4096 blocks in a cycle. Calculated with a block time of one minute, a cycle is 2 days, 20 hours and 16 minutes. As a reward for participating in consensus and maintaining network stability, bakers will receive XTZ as a reward. The reward amount is 16XTZ per block and 2XTZ per signature.
Who Are the Founders of Tezos?
Arthur Breitman was the man who wrote the Tezos white paper — and in a nod to Satoshi Nakamoto, he wrote his works under the pen name L. M. Goodman. He argued that one of Bitcoin’s biggest failings was the lack of a governance process that invited contributions from the community who use the network — as well as the fact that new tokens couldn’t be issued through this blockchain.
He and his wife Kathleen founded a startup called Dynamic Ledger Solutions which was tasked with writing the code that would underpin the Tezos protocol. This company was subsequently purchased by the Tezos Foundation to ensure that it owned all of the intellectual property rights relating to the network.
Why is Tezos unique?
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 utilizes focuses on 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.
Tezos is also unique because of how it has started to be used by high-profile businesses. In September 2020, it was announced that the French banking giant Societe Generale planned to use this blockchain for experimenting with a central bank digital currency.
Big cryptocurrency exchanges such as Binance and Coinbase have also unveiled support for Tezos staking, meaning users can receive rewards based on the XTZ that they hold. This is not a feature that’s seen too widely across digital assets.
How Is the Tezos Network Secured?
Like other blockchains, Tezos uses a proof-of-stake consensus mechanism.
Anyone can become a validator and contribute to the smooth running of the network by making a security deposit. To incentivize honest behavior, rewards are given to those who work in the best interests of the blockchain — and those who act dishonestly risk losing their stake altogether.
What are Tezos Nodes?
Tezos Nodes is a reliability rating of public Tezos Bakers and a service for monitoring the state of node performance for non-public Tezos Bakers.
Working with the baking community, the team developed a baker reliability index that features 10 key indicators. This index will provide you with all the necessary info you need to choose a reliable public baker.
How much are the Block Rewards for Tezos blockchain?
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%. As of May 2021, approximately 78.8% of Tezos tokens have been delegated, including the 10% owned by the Tezos Foundation, so the annualized yield is roughly 5.8%.
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
How do I become a Tezos Baker?
To be qualified as a baker, you would need at least 8,000 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 40 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 1.25 XTZ for each block they endorse.
