Tezos is a secure, future-proof smart contract system. Because Tezos has a built-in consensus mechanism, its protocol can evolve, and incorporate new innovations over time, without the risk of hard forks splitting the market. Tezos is its own blockchain, not a derivative of any other blockchain. We didn’t just fork Bitcoin or Ethereum and add a layer onto it. We built our own from the ground up. Their smart contract language makes it easier to apply formal verification to any smart contract running on the Tezos blockchain. This allows developers to rule out weaknesses in code before uploading that code on the blockchain. Tezos relies on a less onerous, less computationally intensive, and less power-consuming proof-of-stake consensus algorithm, where bonded stakeholders validate transactions.

Technology

Tezos uses powerful technology uniquely suited to the rigorous, specific requirements necessary to enforce smart contracts on a public ledger. It facilitates making those contracts subject to formal verification, a process used in aerospace, medicine, and other industries that need to ensure that code works as intended - thus obviating the need for later correction - before it is uploaded to the blockchain.

Tezos enables innovation via self-amendment. Every blockchain (Bitcoin, Etherereum, ZCash...), can be described by a triplet (S, apply, score)

• S: an internal, mutable, state type. In Bitcoin, this would be the set of unspent outputs
  *apply: a transform which takes a state S, a transaction T, and produces a new state S’
  *score: scoring function which determines the valid blockchain branch. In Bitcoin, this would be the total amount of hashing power on the chain.
  *Tezos augments and improved this model by making apply and score part of the mutable state.

Concern

Although couple of billionaires want to invest in this crypto, there no cap on number of coins and its unlimited supply which i think is a bad idea for long term.

Also, if you dont move your coin for a year it burns out. That is insane to just burn coins if they don't move for a year, what if you're sick in the hospital because you had a stroke or a horrible car accident-your money just gets burnt? Imagine if a bank did that lol.

Cheers :)
