Everyone saw BitcoinCash pump 30%+ after the CME announcement, but how many have kept up with its fundamentals the past ~5 years? Here's an overview of BCH's biggest upgrades since 2022.

2022

Title: Transaction Introspection

Details: Covenants (restrictive spending rules)

Benefits:

-Vaults (time-delayed withdrawals, emergency recovery paths)

-Scaling (shared UTXOs, unilateral exits, mass payouts/deferred expansion)

-Layer-2s/sidechains (no penalty transactions, simpler watchtowers)

2023

Title: CashTokens

Details: Miner-validated minting and transferring of fungible and non-fungible tokens

Benefits:

-Tokenized real-world assets

-Decentralized exchanges

-Algorithmic over-collateralized stablecoins

-Cross-contract communication/composability

2024

Title: Jessica ABLA (Adaptive Blocksize Limit Algorithm)

Details: Blocksize limit automatically adjusts with usage (upper bound of doubling in size each year)

Benefits:

-No need to coordinate future increases to BCH's blocksize limit. (Algorithm can be updated if needed.)

-Node runners can capacity-plan around maximum storage/bandwidth/compute requirements over a given time.

2025

Title: VELMA (Virtual Machine Limits)

Details: Re-targets various limits on BCH smart contracts

Benefits:

-More advanced and efficient smart contracts

-Lower worst-case resource usage for malicious transactions

2026

Title: LAYLA (Loops & Functions)

Details: Loops and functions, fundamental programming concepts, are now safe to implement thanks to the VELMA upgrade.

Benefits:

-Transaction sizes reduced

-Smart contracts become simpler and easier to audit

-Post-quantum cryptography, zero-knowledge privacy, and many other complicated constructions become more practical to implement
