This is an application interface protocol that allows interfacing with any programming language to process transactions.
Tendermint allows decoupling of the application process and consensus process, which allows any application to benefit from the consensus mechanism.
How Membership Services Manage Identity and Access (Part 2)
The Tendermint consensus algorithm is a round-based mechanism where validator nodes propose new blocks in each round.
A locking mechanism is used to ensure protection against a scenario where two different blocks are selected for committing at the same height of the blockchain.
Each validator node maintains a full local replicated ledger of blocks that contain transactions.
Each block contains a header, which consists of the previous block hash, timestamp of the proposal of block, the current block height, and the Merkle root hash of all transactions present in the block.
Tendermint has recently been used in Cosmos ( ) which is a network of blockchains that https://cosmos.network allows interoperability between different chains running on BFT consensus algorithm.
The first zone in Cosmos is called Cosmos hub, which is, in fact, a public blockchain and is responsible for providing connectivity service to other blockchains.
Why This Matters for Blockchain Technology
For this purpose, the hub makes use of Inter Blockchain Communication (IBC) protocol.
IBC protocol supports two types of transactions called IBCBlockCimmitTx and IBCPacketTx.
The first type is used to provide proof of the most recent block hash in a blockchain to any party, whereas the latter type is used to provide data origin authentication.
A packet from one blockchain to another is published by first posting a proof to the target chain.
Key Points to Remember
- Tendermint Socket Protocol (TMSP) This is an application interface protocol that allows interfacing with any programming language to process transactions.
- Tendermint allows decoupling of the application process and consensus process, which allows any application to benefit from the consensus mechanism.
- The Tendermint consensus algorithm is a round-based mechanism where validator nodes propose new blocks in each round.
- A locking mechanism is used to ensure protection against a scenario where two different blocks are selected for committing at the same height of the blockchain.
Going Deeper: Advanced Concepts
The receiving (target) chain checks this proof in order to verify that the sending chain has indeed published the packet.
This scheme addresses scalability and interoperability issues by allowing multiple blockchains to connect to the hub.
Conclusion
Tendermint Socket Protocol (TMSP) 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.
