Lead in: Solana Simplified

Solana is celebrated for its high speed, low costs, high transaction throughput, and low latency. These features have made it an increasingly favored platform among both users and developers for all kinds of decentralized applications.

To help both readers and developers navigate this robust ecosystem, BlockSec has specially curated the "Solana Simplified" series. This series covers the fundamental concepts of Solana, practical guides on analyzing Solana transactions, and comprehensive tutorials on writing Solana smart contracts. Let's dive in. 🙌

Breaking Down: A Comprehensive Overview

In the first part of this series, let's delve into the key concepts of the Solana network, including its operating mechanisms, account model, and transactions. This will lay the foundation for writing correct and efficient smart contracts on Solana.

In this article, we will guide you through writing a Solana program (i.e., a Solana smart contract) for posting and displaying articles. We will cover everything from environment setup and contract logic to program testing.

In the last part, we will introduce Solana's special token mechanism and teach users how to analyze a simple Solana transaction using Phalcon Explorer.

Weekly Web3 Security Incident Roundup | Feb 9 – Feb 15, 2026

Weekly Web3 Security Incident Roundup | Feb 9 – Feb 15, 2026

During the week of February 9 to February 15, 2026, three blockchain security incidents were reported with total losses of ~$657K. All incidents occurred on the BNB Smart Chain and involved flawed business logic in DeFi token contracts. The primary causes included an unchecked balance withdrawal from an intermediary contract that allowed donation-based inflation of a liquidity addition targeted by a sandwich attack, a post-swap deflationary clawback that returned sold tokens to the caller while draining pool reserves to create a repeatable price-manipulation primitive, and a token transfer override that burned tokens directly from a Uniswap V2 pair's balance and force-synced reserves within the same transaction to artificially inflate the token price.

Top 10 "Awesome" Security Incidents in 2025

To help the community learn from what happened, BlockSec selected ten incidents that stood out most this year. These cases were chosen not only for the scale of loss, but also for the distinct techniques involved, the unexpected twists in execution, and the new or underexplored attack surfaces they revealed.

#10 Panoptic Incident: XOR Linearity Breaks the Position Fingerprint Scheme

On August 29, 2025, Panoptic disclosed a Cantina bounty finding and confirmed that, with support from Cantina and Seal911, it executed a rescue operation on August 25 to secure roughly $400K in funds. The issue stemmed from a flaw in Panoptic’s position fingerprint calculation algorithm, which could have enabled incorrect position identification and downstream fund risk.
