Deep Dive ### 1. Mainnet Launch (15 July 2025)
Overview: TAC’s mainnet launched with full EVM compatibility, allowing Ethereum dApps like Curve and Morpho to deploy natively on Telegram’s ecosystem.
The codebase introduced a hybrid architecture combining Cosmos SDK and Ethereum’s Cancun hard fork specs, enabling developers to port Solidity-based dApps without rewriting code. Pre-deployed liquidity pools and cross-chain bridges (via LayerZero) were embedded at launch.
What this means: This is bullish for TAC because it positions the protocol as a gateway for Ethereum’s $500B+ DeFi ecosystem to tap Telegram’s 1B+ users. Users benefit from familiar dApps with lower fees (~$0.01 per transaction).

2. CosmosEVM Architecture (15 July 2025)
Overview: The chain uses Tendermint’s Delegated Proof-of-Stake (DPoS) consensus, requiring validators to bond $TAC and users to delegate tokens for 8–10% APY.
Code optimizations reduced block finality to ~2 seconds, matching Solana’s performance while maintaining EVM compatibility. The architecture also introduced a gas fee converter that automatically swaps TON (used for fees) to $TAC, creating buy pressure.
What this means: This is neutral for TAC in the short term, as the DPoS model centralizes validation among a few nodes, but the speed upgrade improves user experience for Telegram-based mini-apps.

3. Babylon Bitcoin Staking Integration (15 July 2025)
Overview: Validators must bond both $TAC and Bitcoin (via Babylon’s protocol) to participate, linking TAC’s security to Bitcoin’s proof-of-work.
The codebase added slashing conditions where validators lose bonded BTC if they act maliciously. This hybrid model aims to reduce the "nothing-at-stake" risk common in DPoS chains.
What this means: This is bullish for TAC because it combines Bitcoin’s battle-tested security with TAC’s high throughput, potentially attracting institutional validators like Chorus One.

Conclusion
TAC’s codebase updates focus on interoperability (EVM+TON), speed (~2s blocks), and hybrid security (Bitcoin staking). While the mainnet’s $800M TVL debut signals strong adoption, the reliance on centralized validators and unproven Bitcoin slashing mechanics pose risks.
How will TAC balance decentralization with its ambition to onboard 1B Telegram users?
