StarkWare and Sui launched privacy features this week allowing users to conceal transaction data while maintaining auditability and regulatory oversight. StarkWare's STRK20 framework for ERC-20 tokens on Starknet enables shielded balances and viewing-key-based disclosure under lawful request. Sui introduced a public beta for confidential transfers, hiding transaction amounts but allowing authorized access for compliance. The launches signal a shift toward institutional-friendly privacy models. Recent events, including a court-ordered freeze of funds in Zama's USDC wrapper and a bug disclosure by Zcash, have pushed privacy projects to accelerate compliance roadmaps and address reliability concerns.

Sui (SUI) launched confidential transfers in public beta on Devnet, hiding token balances and transfer amounts while keeping sender, receiver, and auditor access visible. The feature uses Twisted ElGamal cryptography and zero-knowledge proofs to validate transfers without revealing amounts. Unlike Monero, which hides all transaction details, Sui's design preserves compliance controls such as freeze and seize powers, with optional auditor keys. This targets institutions like payment firms and stablecoin issuers that need privacy without full anonymity. Partners including TRM Labs and Merkle Science are testing the system for risk scoring and monitoring. The move comes after Sui experienced three mainnet outages in late May. SUI token price rose nearly 5% following the announcement, trading at $0.76.

Sui co-founder Adeniyi Abiodun announced on June 5 that confidential transfers will be added to the Sui network, using range proofs to hide transaction amounts while protocol-level checks enforce supply integrity. This design aims to prevent exploits like the Zcash counterfeiting bug. The move is part of a broader push into privacy and agent payment infrastructure, including free tier payments and native payment intents for AI agents. Abiodun emphasized the team's focus on building through the bear market, following recent network outages and price declines.

Sui network developers attributed last week's three separate outages, totaling over 15 hours of downtime, to crash bugs in gas charging logic and a validator synchronization issue. The first two outages on May 28-29 resulted from a conflict between gas calculations and a new address balances feature in release 1.72, while a third was caused by a latent bug affecting randomness preservation during an epoch change. The Sui Foundation acknowledged accepting heightened risk with an interim fix to restore operations quickly. User funds were not at risk and no committed transactions were reverted. The price of SUI dropped 18% over the past seven days to $0.86, amid a broader market dip. These incidents mark Sui's third major reliability failure since its 2023 mainnet launch, following a two-hour transaction scheduling bug in November 2024 and a six-hour consensus divergence in January 2026.

Sui Mainnet has resumed normal operations after three outages on May 28-29, 2026, all caused by bugs in the 1.72 software upgrade. The first outage, lasting from 7am to 1:30pm PT, stemmed from a fee charging error when two transactions attempted to spend from the same address balance simultaneously, causing a negative balance. Validators deployed an interim fix, but a second outage occurred at 5am PT on May 29 due to an edge case where an error code bypassed the guard. A more complete fix was deployed by 8:30am. A third outage from 1:30pm to 7:20pm PT occurred at an epoch change when validators restarted to adopt the fix, but a latent bug prevented the network from recording a failed setup process, causing end-of-epoch logic to stall. No user funds were lost, and no confirmed transactions were reverted. SUI token traded around $0.88, down 2.57% in 24 hours. The Sui Core Team outlined investments to improve resilience, gas charging logic, and failure containment.

The Sui Foundation implemented a major upgrade to fix bugs that caused three outages on the Sui Network, resulting in over 15 hours of downtime across two days. The outages occurred Thursday and Friday, with the longest lasting over eight hours. All systems are now operational as of Monday. The foundation said the outages stemmed from crash bugs introduced in the 1.72 software release, affecting gas charging and causing negative balances. An interim fix for the initial bug triggered a third outage. No user funds were at risk and no committed transactions were reverted. The Sui (SUI) token has declined approximately 11% since the outages, trading at around $0.88 as of Monday, down from $0.99 before the first outage. Sui is the 13th-largest blockchain by total value locked at $519 million.

The Sui mainnet experienced three outages over May 28-29 due to a bug introduced in the v1.72 upgrade, which affected gas-charging logic for transactions using both the new address-balance feature and traditional coin objects, causing validators to crash. The first halt lasted nearly seven hours; an interim fix restored service but carried a low-risk known issue. A second outage occurred the next morning when a transaction triggered a masked variant of the bug, bypassing the interim patch. A robust fix was deployed, but during restart, validator participation in the on-chain randomness protocol fell below threshold, causing randomness to disable. A latent bug failed to persist the disabled state, leading to a third, six-hour halt as transactions stalled. No user funds were lost, and no transactions were reverted. The SUI token dropped about 8% during the incidents and traded near $0.90, down roughly 19% for the week.

Sui Foundation attributed three mainnet outages on Thursday and Friday to two bugs in its v1.72 upgrade. The first two halts stemmed from a gas-charging flaw triggered by a new address balances feature, causing negative balances. An interim fix, known to carry a low halt risk, led to a second outage. A third halt arose from a latent randomness bug that surfaced during validator restarts. Sui said all bugs have been addressed, no user funds were lost, and no transactions reversed. AI agents expedited diagnostics.

The Sui blockchain experienced its second network disruption in as many days on Friday, halting block production for over three hours. The Sui team attributed the outages to the interaction of the 1.72 release, which introduced address balances and gas charging logic. A temporary fix implemented after Thursday's six-hour outage had a low probability of causing disruption, but a long-term fix has since been deployed by a majority of validators. The January outage, caused by a consensus bug, also halted block production for over six hours, though user funds were never at risk. The incidents highlight potential failure points in high-throughput blockchain networks, as well as the broader impact of outages on centralized service providers.

The Sui blockchain experienced a network stall for the second consecutive day on Friday, causing its native token SUI to drop 20% over the past week to $0.89, now 83% below its all-time high. The outages were caused by a bug in the 1.72 release related to Address Balances and gas charging logic. A long-term fix was implemented by validators, and the network resumed normal operations. Outages have been a recurring issue for Sui, with three significant incidents this year.
