Deep Dive
1. Core 5.0 Testnet Nears Completion (November 2025)
Overview: This is a major upcoming version of the Core network. The testnet is reported to be 90% complete, with core improvements focused on making the network more reliable and efficient for developers and users.
The development update highlights breakthroughs in block producer stability, transaction flow, and overall network architecture. These are foundational upgrades that precede a public testnet launch, indicating the team is in the final stages of preparing a more robust network for builders.
What this means: This is bullish for CORE because a successful upgrade to Core 5.0 could lead to a faster, more stable blockchain. This improves the experience for developers building apps and for users making transactions, which is essential for long-term ecosystem growth.

2. Network Upgrade to v1.0.17 (June 2025)
Overview: This was a scheduled network upgrade that exchanges like Bybit supported to ensure service continuity. It focused on backend infrastructure and protocol optimizations rather than introducing new user-facing features.
The upgrade proceeded smoothly as a routine maintenance update, aligning with Core's technological progression. Its primary goal was to maintain a stable trading and wallet environment without disrupting the native CORE token's operations.
What this means: This is neutral for CORE. Such upgrades are essential for the network's health and security but don't directly change how most users interact with the chain. It demonstrates ongoing developer commitment to maintaining and improving Core's underlying technology.

3. Staking & Security Overhaul (October 2023)
Overview: This was a substantial mainnet upgrade that fundamentally improved the staking experience and network security. It activated at block 8,020,000 and introduced features that are still core to the network's functionality today.
Key changes included eliminating the one-day reward penalty when users redelegate CORE tokens, allowing split delegations across multiple validators, and implementing a gas price limit to protect relayers from Miner Extractable Value (MEV) attacks. It also resolved issues with block production and smart contract transactions.
What this means: This was very bullish for CORE as it made staking more flexible and profitable, encouraging user participation. It also made the network more secure against certain attacks, building trust in the ecosystem. These improvements directly benefit token holders who stake to earn rewards.
