DeFi, payments, tokenization, Soroban, governance, and project launches — curated daily from publications, project blogs, and community channels across the Stellar blockchain ecosystem.
The Stellar Development Foundation explains the Stellar Consensus Protocol (SCP) through a detailed walkthrough of how distributed consensus works. The article covers quorums, federated voting, nomination and ballot protocols, and provides a concrete example of how nodes reach agreement on transaction sets.
The Stellar Monthly Roundup for September 2019 covers ecosystem updates including collaborations, AMAs, new hires at SDF, developer releases, community fund proposals, and ecosystem projects like Cowrie Systems and Bitbond. Highlights include the upcoming Meridian conference in Mexico City and a proposal to disable inflation. New features on stellarbeat.io and protocol upgrades prepare the network for future improvements.
Stellar Development Foundation released stellar-core v11.2 with automatic quorum configuration and a quorum intersection checker to help validators manage Byzantine Agreement Systems more easily and safely.
Stellar network halted for nearly two hours Wednesday when enough validator nodes stopped, preventing consensus. The incident highlighted risks of rapid decentralization, though SDF nodes remained operational.
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 developer created 'stcli', a simple, single-file Python REPL command-line wallet for Stellar-based assets like ETH, BTC, and EURT. It emphasizes code transparency, ease of review, and support for testing Stellar remittance functions including federation and compliance. The wallet addresses gaps in existing options by being Linux CLI-friendly and fully auditable.
Stellar Development Foundation publishes technical specifications and roadmap for implementing Lightning Network on Stellar, enabling instant, low-fee off-chain payments through state channels and payment channels.
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.
