Tezos is a generic self-amending cryptographic ledger, which means that it not only allows decentralized consensus on the state of the blockchain but also allows consensus on how the protocol and nodes are evolved over time.
Tezos has been developed to address limitations in the Bitcoin protocol such as issues arising from hard forks, cost, and mining power centralization due to PoW, limited scripting ability, and security issues.
Self-Amending Ledger with On-Chain Governance
It has been developed in a purely functional language called OCaml.
The original research paper is
The architecture of Tezos distributed ledger is divided into three layers: the network layer, consensus layer, and transaction layer.
This decomposition allows the protocol to be evolved in a decentralized fashion.
For this purpose, a generic network shell is implemented in Tezos that is responsible for maintaining the blockchain, which is represented by a combination of consensus and transaction layer.
This shell provides an interface layer between the network and the protocol.
Why This Matters for Blockchain Technology
A concept of seed protocol has also been introduced, which is used as a mechanism to allow stakeholders on the network to approve any changes to the protocol.
Tezos blockchain starts from a seed protocol compared to a traditional blockchain that starts from a genesis block.
This seed protocol is responsible for defining procedures for amendments in the blockchain and even the amendment protocol itself.
The reward mechanism in Tezos is based on a PoS algorithm, therefore there is no mining requirement.

Going Deeper: Advanced Concepts
Contract script language has been developed in Tezos for writing smart contracts, which is a stack-based Turing complete language.
Smart contracts in Tezos are formally verifiable, which allows the code to be mathematically proven for its correctness.
Tezos has recently completed crowdfunding via ICO of 232 million USD.
Conclusion
Tezos represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
