Stellar public network upgraded to Protocol 15 at 1600 UTC, introducing Claimable Balances and Sponsored Reserves features to enable more user-friendly app development on the network.
Protocol 15 introduces claimable balances, enabling payments to accounts without requiring pre-existing trust lines. This two-part payment mechanism solves a major friction point in asset transfers while enabling new payment primitives like recoverable and multi-recipient payments.
Stellar is skipping Protocol 14 and upgrading the public network to Protocol 15 on November 23, 2020. The change addresses a rare bug discovered during testnet testing that could have caused validator crashes. Developers running Stellar Core or Horizon must install updated versions before the upgrade.
Stellar validators will vote on Protocol 15 upgrade on November 23, 2020, introducing Claimable Balances and Sponsored Reserves to simplify user onboarding and reduce friction for anchors and app developers building on the network.
Stellar Development Foundation announced that Protocol 14 will be skipped in favor of Protocol 15 due to a critical bug discovered during testnet testing. The public network upgrade vote has been rescheduled to November 23, 2020, with detailed upgrade instructions provided for validators, Horizon operators, and SDK users.
The Stellar Community Fund manager shares six strategies for winning SCF grants: serve your audience, pick the right fund tier, exceed guidelines, engage the community, emphasize marketing, and keep iterating. Success requires balancing technical quality with presentation and community involvement.
The Stellar Development Foundation launched Stellar Community Fund 2.0, splitting the grant program into two funds (Seed and Lab) and introducing a nomination panel plus quadratic voting to address voter fatigue and improve project selection fairness.
SEP-30 enables user-friendly non-custodial wallets by eliminating recovery phrases and passwords. Users log in with just a phone number while maintaining full account control through device keys and distributed recovery servers. Vesseo, a USD savings app on Stellar, demonstrates this approach in production.
Part two of a key management series explains how Stellar accounts work, covering public/secret keys, master keys, multi-signature capabilities, and common wallet strategies. The post introduces SEP-30 as a better approach to user-friendly key management and account recovery.
Stellar Development Foundation introduces SEP-30, an ecosystem standard for non-custodial wallets that simplifies key management and recovery using multi-signature technology. Users can recover accounts through identity verification rather than managing backup keys, making blockchain more accessible to mainstream users.
The Stellar Development Foundation proposes raising the network's minimum transaction fee from 100 stroops to 10,000 stroops per operation to combat failed arbitrage bot transactions that clog the ledger and cause unpredictable surge pricing.
The Stellar Development Foundation is asking builders and businesses on Stellar to complete a brief survey to provide feedback on their integration, use cases, and feature requests. This helps SDF better understand community needs and allocate resources more effectively.
Stellar Development Foundation launched redesigned developer documentation at developers.stellar.org, featuring improved navigation, updated content, and new learning paths for asset issuance, anchor services, and app development.
The Stellar public network successfully upgraded to Protocol 13, introducing new features like fee-bump transactions and fine-grained asset authorization. Developers must update their software to avoid compatibility errors.
Protocol 13 introduces fee-bump transactions to the Stellar network, allowing users to increase transaction fees without requiring new signatures from all parties. This solves the problem of pre-signed transactions becoming unexecutable when network fees rise unexpectedly.
Stellar Core Protocol 13 introduces three major features: fee bumps for flexible transaction fee management, fine-grained asset authorization for regulated assets, and multiplexed accounts with built-in memos for custodial services. The public network will vote to upgrade on June 18, requiring all ecosystem participants to update their software.
The Stellar Development Foundation released a daily-updated analytics dataset on Google BigQuery, enabling 10-100x faster queries across the entire history of Stellar network transactions. The dataset includes accounts, ledgers, operations, trades, and other ledger state information, with free trial access available through Google Cloud.
Stellar Protocol 13 upgrade is coming to mainnet on 06/18/2020. Developers must update Horizon, SDKs, and custom integrations before the network votes to upgrade, or their software will break.
The Stellar Development Foundation's web products team is seeking community feedback on a redesigned version of the Stellar developer documentation and API reference. The new docs feature improved navigation, modular learning paths, and updated content while maintaining existing functionality.
The Stellar Development Foundation reflects on why open source is the right model for building networks, highlighting documentation, transparency, collaboration, and diversity as key pillars that enable Stellar to thrive across borders and time zones.
The Stellar Development Foundation released its Q1 2020 quarterly report, highlighting progress on strategic growth pillars including Horizon API improvements, policy advocacy, marketing initiatives, and a strategic investment in DSTOQ to expand financial access in emerging markets.
Stellar Development Foundation revamped Stellar.org with a new project directory, updated SDF mandate detailing treasury deployment, and lumen supply metrics documentation to improve ecosystem transparency and support for builders.
Stellar.org's new homepage features runnable code samples for network features like payments and asset issuance. To handle testnet resets every 3 months, the team built an automated script that checks for account existence and recreates necessary accounts, plus a function to return unused testnet lumens to Friendbot to prevent resource depletion.
The Stellar Winter Roundup 2019 recaps key achievements and events from December through October, including ecosystem expansion, the Meridian conference, lumen distribution updates, and new partnerships. Highlights feature SDF's new mandate, Horizon and Core releases, Stellar Community Fund voting, and integrations like Travala.com and BitGo support for XLM. It also announces new hires and job opportunities at SDF.
Stellar Development Foundation reflects on 2019 achievements: team grew from 11 to 56 employees, Stellar accounts doubled to 4.1M, protocol upgrades improved capacity and fairness, and ecosystem matured with stronger validator infrastructure and real use cases like AnchorUSD.
