Hedera Hashgraph (HBAR)
**Leaderless architecture completely eliminates MEV, Frontrunning, Sandwich Attacks, etc.** Any chain with a Block Leader has these problems and has some way of trying to "mitigate" it. **Don't mitigate attack vectors, eliminate attack vectors!** Block Leaders are a security issue, since if you shut down the centralized single leader (DDOS), you shut down the network.
**ABFT (Asynchronous Byzantine Fault Tolerance).** This was an unsolved math problem in distributed computing since \~1982 (over 40 years). Dr. Leemon Baird solved it using **Gossip about Gossip with ABFT Virtual Voting**. It is the gold standard of consensus algorithms and will never be beaten. **Perfect mathematics.**

**Fees are fixed in USD, and paid in HBAR.** This makes it easy to forecast costs for users.

It has **Unlimited Scalability**. The current throttle is 10,000TPS, but that is a conservative throttle on a single shard. Add more nodes/shards to add more scale, as needed. Unlimited.
**Modular Design for easy upgrades**. Hedera has the perfect mathematical foundation of Gossip about Gossip with ABFT Virtual Voting. Everything on top of that is plug-and-play. This is why it will only take changing a couple lines of code to upgrade to Post-Quantum Security. Hedera should be Post-Quantum with ML-KEM (waiting on libraries) and Falcon Signatures (waiting on NIST) by 2027. Add that Hedera is already SHA384 and AES256, both Post-Quantum. **Upgrades for Hedera are maintenance. Upgrades for all other chains are open heart surgery.**

It is **Guaranteed Decentralization over time/scale**, meaning it's Nakamoto will only increase as it scales. All nodes are essentially equal (Gini and Theil Index), so adding more nodes/shards only increases Nakamoto.

Full Hedera code base has been **open sourced with Apache 2.0 and donated to Linux Foundation.**

**Private HashSpheres, ZK Proofs, and encrypted messages to Mainnet**, means you can use your own private network that seamlessly connects to Mainnet, or keep your transactions private in many ways.

**Cross-Ledger Protocol (CLPR)** enables cryptographically-secured communication and token transfers between independent blockchain networks–all without bridges, pooled liquidity or intermediary validator networks. Bridges are the most hacked/scammed part of crypto, so **CLPR offers bridgeless bridging.**

It's also **governed and being built on by a diverse set of Global Fortune 1000's and Universities**. They have 3 year terms (max 2 consecutive terms, max 39 members), and all have 1 equal vote on governance issues. This means the Council rotates and power is never consolidated.

In short TLDR: leaderless, best possible ABFT consensus, best possible SHA384 AES256 ML-KEM Falcon Signatures Post-Quantum Security, Unlimited Scalability, Guaranteed Decentralization over time/scale, fully open sourced with code donated to Linux, private HashSphere, connect to any network with CLPR, with a rotating expert governing council that is building enterprise grade solutions.
