A few things I am still unclear about: - How do nodes find each other? - Where is the mempool? :) - The steps of the consensus mechanism? - How does the network pick the winning block/validator? - How does the network handle node desynchronization?

Block propagation and consensus 9. Other nodes receive and verify new blocks 10. They append the block to their local chain 11. The longest chain becomes the new reality

Block creation and proposal 5. Validators/Miners select transactions from the mempool 6. They create a candidate block 7. The network picks the winning block based on the consensus mechanism. 8. They broadcast the winning block to other nodes

Transaction flow 1. User signs a transaction and sends it to a node 2. Node verifies the transaction 3. Node broadcasts the transaction to the mempool 4. Other nodes also validate the transaction

◼️40/100: Block-by-Block One thing I learned about: Alternatives to using blockchain nodes Blockchains do not need always to use full-nodes for every task in the network. They can use alternatives suited to their goals, circumstances, and constraints. Examples: - Light clients: performs trust-minimized verification by requesting proofs from ful nodes. - Data availability layers: store and serve block data apart from execution nodes. - Layer2 and sidechains: process data off-chain and rely on proofs or state roots. - Blockchain indexers: store data and allow queries nodes do not support. - Remote or federated apis: third-party on-chain data providers 🔽🛠️Resources🔽

Yes, very few people know how to approach this topic. 😅 What you are doing is valuable for lots of companies. Is there a domain you are especially focusing on inside stablecoin adoption?

◼️38/100: Block-by-Block One thing I learned about: Blockchain node components Nodes work differently depending on the blockchain and their role within the blockchain. Some general components & functions across the stack: - P2P Networking - Mempool Management - Consensus Execution - State & Ledger storage - RPC/API Layer - Synch mechanisms
