Jan 30Performance Comparison Analysis: Wasmer vs. WASMTimeRecently I had a project regarding the security and the performance of WASM compilers for a blockchain ecosystem. I realized there are two major WASM interpreters/JITs, especially popular among the blockchain networks, i.e., WASMER and WASMTIME. wasmer — Interpreter/JIT made at wasmer.io. …Wasm3 min readWasm3 min read
Dec 16, 2022When Panic Becomes Dangerous in RustWhat is panic ? Sometimes, unexpected things occur in your code; for these scenarios, Rust has the Panic! macro. This Macro in Rust signals that the code is in a state it cannot handle and must tell the process to stop instead of trying to proceed with invalid or incorrect values. There are two…Rust4 min readRust4 min read
Sep 22, 2022Directed Acyclic Graph (DAG) vs BlockchainWhat is DAG? A Directed Acyclic Graph (DAG) is a particular data structure class connecting various information elements. We can imagine as DAG protocol as a sequence of nodes and edges connecting them. The edges are unidirectional, implying that info cannot move in opposite directions. Any information in the DAG cannot move back…Directed Acyclic Graph3 min readDirected Acyclic Graph3 min read
Jul 19, 2022My Thoughts on Plasma Ethereum L2Plasma is a layer-2 scaling solution that was initially proposed by Vitalik Buterin and Joseph Poon in 2017. The whole concept has been described in its white paper “Scalable Autonomous Smart Contracts”. Plasma, in a nutshell, claimed to be a framework for building scalable applications. …Ethereum5 min readEthereum5 min read
Jul 10, 2022A Quick Review of the Major Changes on Ethereum V2.0In Ethereum 2, the network will be upgraded to a proof-of-stake blockchain and present shard chains and a beacon chain. This advancement will lower energy consumption and improve the possible velocity and number of transactions. Nevertheless, it has also raised considerable concerns regarding the future of the Ethereum network. With…Ethereum2 min readEthereum2 min read
Jun 3, 2022Ethereum Rollups ExplanationWhat is the challenge? Ethereum blocks are restricted to the amount of data they can maintain. For instance, image a block can only do 10 transactions. For example, if 10,000 people want to do a transaction simultaneously, Ethereum will pick 10 of the highest bidding fees first. Because gas fees are based on the…Ethereum4 min readEthereum4 min read
May 18, 2022What the F**K is Front-Running Attack?What the hell is MEV ? When a user broadcasts an Ethereum transaction, it doesn’t become part of the blockchain until a miner puts it in a block. This process takes some time. Note that, DeFi has to supply some incentives for all partners. Mining grants and transaction fees allow miners to earn rewards for the…Ethereum3 min readEthereum3 min read
May 6, 2022Security Audit of Solana Smart ContractsSolana smart contracts can be written in Rust or even C. Solana presents a distinct smart contract model to traditional EVM-based blockchains. A smart contract is read-only or stateless and retains only program logic. Once deployed, smart contracts can be interacted with by external accounts. Security audits for Solana smart…Solana Blockchain2 min readSolana Blockchain2 min read
