What is Tezos?

  • Tezos is a blockchain platform that supports smart contracts and dapps, supported the thought of a digital commonwealth, during which governance is democratized in an efficient and sustainable manner to avoid costly hard-fork scenarios.
  • In 2017, the Tezos ICO raised $232 million in BTC and ETH, making it one among the most important ICOs within the industry. Based in Switzerland, the Tezos Foundation spearheads efforts to support wider adoption of the protocol.
  • Within the network, XTZ is that the token used for all operations. With the incorporation of features like Liquid Proof-of-Stake and on-chain governance, throughput is traded for a better level of decentralization.
  • Tezos relies on Liquid Proof of Stake (LPoS), with full support of Turing-complete contracts. within the Tezos network, block generation is mentioned as baking while validators are referred to as bakers

Tezos’ core features include:

Liquid Proof-of-Stake (LPoS): Tezos employs a Proof-of-Stake consensus mechanism designed to maximise decentralization of governance and encourage participation among XTZ holders of all sizes. LPoS maintains a dynamic set of validators which will expand with the network, and allows stakeholders to delegate rights to other holders.

On-chain governance: All stakeholders can participate in protocol governance either directly or indirectly, through delegation. An election cycle provides a procedure for stakeholders to propose amendments and reach an agreement.

Self-amendment: The protocol can “upgrade itself” without having to fork the network into two different blockchains. Decisions to vary facets of the protocol come from within the community of stakeholders and are implemented through the on-chain governance process. Self-amendment is meant to scale back coordination and execution costs for protocol changes and facilitate a smoother transition between network iterations.

2. Tezos’ key features

To mitigate the governance issues faced by many blockchain protocols, Tezos employs variety of pioneering features, which are rooted first and foremost within the underlying consensus algorithm. The term Liquid Proof of Stake was chosen to differentiate the model employed by Tezos from Delegated Proof of Stake (DPoS) chains like EOS or NEO. While DPoS blockchains split block production rights evenly between a group of active block producers, LPoS assigns the probability of block production supported the proportion of stake held by each validator; and there’s no limit to the amount of bakers within the system.

Liquid Proof of Stake

Tezos uses inflationary block rewards and transaction fees to incentivize validators (or “bakers” in Tezos terminology) to participate in consensus. Bakers contribute their computing power to the network to validate transactions. To participate, bakers must own a minimum of 8,000 XTZ (or 1 roll). Rolls are aggregated at the baker level, which suggests a baker’s baking power is proportional to the amount of tokens (or “tez”) held, rounded right down to the closest roll. The more rolls held by a baker, the upper the prospect they’re going to bake subsequent block.

Bakers and Endorsers (i.e., bakers that check block validity) are chosen randomly every cycle (approximately every three days or 4096 blocks). Baking rights also follow a priority order, which is randomly selected by the protocol per block. Should an appointed baker fail to broadcast a block within a 1 minute time-frame , responsibility shifts to the second baker on the priority list. Each block is baked, then endorsed (witness the block and checked that it had been valid) by 32 other randomly assigned bakers. All Bakers and people endorsing must post a deposit for every block during which they play a task validating.

This deposit is forfeited if any malicious activity occurs. a gift of 40 XTZ is awarded for baking a block, additionally to the sum of the transaction fees. Meanwhile, each Endorser is awarded 1.25 XTZ per block.

Liquid Proof of Stake allows XTZ holders to transfer, or delegate, validation rights to other token holders without transferring token ownership. Holders who possess 8,000 XTZ (1 roll) but don’t wish to participate directly in baking can simply allocate their holdings to a baker, which successively grants that baker a better probability of validating blocks. The baker then shares some of the revenue received for participating in consensus (in addition to collecting a fee) with all token holders who delegated tokens. Bakers compete for holders’ XTZ by charging lower fees than others. An aggregated list of baking services is out there here. Binance Staking supports Tezos staking with no baking fee.

On-chain governance and self-amendment

On-chain governance may be a mechanism for facilitating the self-amending feature of the Tezos blockchain. Tezos employs this technique to incentivize developers by rewarding them for his or her contributions, additionally to democratizing the evolution of the protocol itself through the voting process, which provides a viable alternative path to a tough fork.

Self-amendment is implemented to scale back the disruption and costs related to hard forks, while simultaneously opening an avenue to seamlessly and democratically integrate innovative changes.

The self-amendment process is split into four periods: the Proposal Period, Exploration Vote Period, Testing Period and Promotion Vote Period. Each of those four periods lasts eight baking cycles (i.e., 32,768 blocks or roughly 22 days, 18 hours), which is approximately three months from proposal to activation. A more detailed breakdown of every period follows:

  • Proposal period: delegates (bakers) submit protocol amendment proposals. At the top of the proposal period, the proposal with most supporters is chosen . If there are not any proposals or there’s a tie, a replacement proposal period starts.
  • Exploration Vote period: delegates vote whether to check the winning proposal. At the top of a search vote period, if participation reaches the quorum (what may be a quorum) and therefore the proposal features a supermajority (8/10 Yay or Nay votes) in favor, the method moves to the testing period.
  • Testing period: a test chain is forked for 48 hours to check the proposed change. Following this era the ultimate voting period begins.
  • Promotion Vote period: delegates can cast one vote to market the testnet chain to the mainnet. If a supermajority is met, the testnet is activated as mainnet.

As the primary actors maintaining the network, bakers are also liable for casting votes within the formal upgrade process. Voting rights are assigned to baker delegates supported the amount of rolls in their stake at the start of every voting period as follows: 1 vote = 1 roll = 8,000 XTZ. Both voting periods function within the same manner. During the vote period, a delegate can cast one Yea, Nay,or Pass. A vote is merely successful if a. it’s a supermajority and b. the participation reaches the present quorum. In line with the decentralized ethos underlying Liquid Proof of Stake, XTZ holders can choose a baker whose vote is aligned with theirs and delegate their stake, thereby electing a representative on their behalf.

3. Economics and provide distribution

In July 2017, Tezos raised $232 million in BTC and ETH through an Initial Coin Offering, making it one among the most important ICOs within the industry. The genesis block began in June 2018, with 608 million XTZ getting into circulation; it maintains no supply cap at this moment.

Tezos’ block time is one minute and therefore the current annual inflation is 3.6%, implemented with the Carthage 2.0 upgrade.

The previous rate of inflation of XTZ was 5.5%. the typical transaction fee stands at $0.00232. Nearly 80% of the present supply is staked and therefore the current circulating supply is 704,111,107 XTZ (as of March 2020).
