Study Notes
Scalability in Blockchain Networks
- Main purpose of scalability: To handle increasing transaction volume and user activity without compromising network performance or security.
- Scalability Trilemma: Attempts to balance decentralization, security, and scalability.
- Not a scalability solution: Data mining is not directly related to scalability solutions.
- Data structure associated with scalability: Merkle trees play a crucial role in efficiently verifying and updating transaction data.
- Best blockchain for secure, internal use: Permissioned blockchains are best suited for private, controlled environments within an organization.
Segregated Witness (SegWit)
- Benefit of SegWit: Reduces transaction size, allowing for more transactions per block.
- Implementation: First implemented in Bitcoin Core (Bitcoin's software).
- Disagreements (2018): Disputes arose regarding the potential impact on Bitcoin's scaling trajectory and future development.
Scalability Solutions
- Not a type of scalability solution: Parallel processing, while useful in general, is not specifically a blockchain-related scalability solution.
- Sharding: Divides the blockchain into smaller segments (shards), allowing for parallel processing of transactions.
- Consensus mechanism for efficient block confirmations: Proof-of-Authority (PoA) can achieve faster confirmations than Proof-of-Work (PoW).
- Greedy Heaviest-Observed Sub-Tree (GHOST) protocol: One of the main advantages is its ability to prevent "orphaned" blocks and wasted computational effort.
- Data structure facilitating non-conflicting transactions: Uncle blocks allow for transactions from alternate chains to be incorporated into the main chain.
- Hedera Hashgraph security: Uses an asynchronous Byzantine Fault Tolerance (aBFT) mechanism.
- Not a method of improving scalability: Decentralization is a core principle of blockchain but not a method for improving scalability.
- Role of 'uncle blocks' in GHOST: They represent blocks that are not directly part of the main chain but can still contribute valid transactions.
Block Directed Acyclic Graph (DAG)
- DAG statement: A DAG allows for transactions to be confirmed without relying on a linear block chain, potentially improving scalability.
- 'Gossip about Gossip' (Hedera Hashgraph): Describes how each node receives information from other nodes, validating and spreading confirmed transactions throughout the network.
Layer 2 Solutions
- State channels advantage: Allow for fast, off-chain transactions that only need to be settled on-chain occasionally.
- State channels challenge: Requires both parties involved to stay online and actively participate.
- Sidechains relation to main blockchain: Operate alongside the main blockchain, enabling cross-chain interoperability.
- Example of a sidechain: Liquid Network extends Bitcoin's features and offers faster transaction times.
- Layer 2 solution for micropayments: Lightning Network facilitates instant, low-cost payments over the Bitcoin blockchain.
- Potential issue with sidechains: Security concerns related to bridges between the main chain and sidechains.
- Rollups description: Bundle transactions together and process them off-chain, then submit the aggregated data to the main chain for verification.
- Challenge with sidechain integration: Ensuring seamless communication and data transfer between the sidechain and main chain.
