Stellar suffered a critical inflation bug in April 2017 where an attacker exploited the merge function to create 2.2 billion XLM (worth ~$10M at the time). The SDF patched the bug, disclosed it in release notes, and burned equivalent XLM from reserves to prevent dilution.

A hacker stole over $400,000 in Stellar lumens by compromising BlackWallet's DNS server, redirecting deposits of 20+ lumens to another wallet. The attacker quickly moved most funds out, with some sent to Bittrex.

The Stellar Foundation released details on its new Stellar Consensus Protocol, based on federated Byzantine agreement, designed to replace the existing consensus mechanism. The protocol has been stress-tested to handle 100 million accounts and hundreds of transactions per second, with deployment targeted for summer.

A ledger fork in the Stellar network sparked debate over the Ripple consensus protocol's safety. Stellar Development Foundation attributed the incident to protocol flaws, while Ripple Labs disputed the claims, arguing the issue stemmed from Stellar's modifications to the code.

Stellar experienced a ledger fork due to weaknesses in its Ripple-based consensus algorithm. The network temporarily switched to a single validator node and is prioritizing development of a new provably correct consensus system to prevent future forks and double-spend risks.

Stellar Development Foundation removed a partial payments feature from the protocol after discovering it could cause fund loss if anchors weren't aware of the DeliveredAmount field requirement. The legacy feature has been eliminated and all known anchors were notified.

Stellar network experienced a 16-hour outage on September 20, 2014, caused by validator nodes running out of RAM, halting consensus and all transactions. The foundation addressed communication gaps and began work on scalability improvements to prevent recurrence.
