XRP Ledger upgrade brings back features once pulled over critical bugs

The XRP Ledger (XRPL) is preparing to release an upgrade, xrpld 3.3.0, that will ask its validators to approve five amendments, including revised versions of two features—Batch and Permission Delegation—that were previously pulled due to critical security flaws. Batch allows up to eight cross-account transactions to execute atomically (meaning all succeed or none do), and Permission Delegation lets institutions delegate narrowly scoped signing authority without giving full control. Both had been disabled after security researchers discovered vulnerabilities that could lead to unauthorized transactions or fee draining, but the upcoming release offers revised, presumably safer versions.

In addition to the revised Batch and Permission Delegation, the upgrade introduces three new amendments. Confidential MPT combines zero-knowledge proofs with elliptic-curve encryption to keep balances and transfer amounts private on Multi-Purpose Tokens, while still allowing verification by auditors or regulators if needed. Sponsored Fees and Reserves enables institutions to pay XRP transaction fees and reserve requirements on behalf of other accounts, removing the necessity for every user to hold XRP directly. Dynamic MPT allows token issuers to specify certain properties that can be changed without a full token migration, thus facilitating updates like fee or metadata changes.

These five amendments require network-wide approval from trusted validators, needing at least 80% support for two consecutive weeks before activation. In the past, Batch and Permission Delegation failed to secure enough backing and were removed to protect the network’s integrity. The new amendments mark a significant development as they aim to enhance XRPL's capability to support scalable tokenized assets and their use cases such as global transfers, trading, collateralizing, and settlement. The approval process underscores the decentralized governance of the network, keeping ultimate decisions in the hands of validators rather than Ripple.

Overall, this upgrade represents a cautious but forward-moving evolution for the XRP Ledger, as it brings back previously flawed features with improved security and introduces new capabilities to increase privacy, usability, and token flexibility. However, the ultimate adoption of these features depends on the voting outcomes among the validators, with no guarantees that any or all will pass.
