The network cut block intervals from 750 milliseconds to 450 milliseconds and raised benchmark throughput to roughly 5,200 transactions per second between January and June 2026. The update also detailed a next generation Layer 1 architecture targeting over 100,000 transactions per second, alongside continued research into quantum resistant security measures.<h2 id="b-first-half-performance-gains-set-the-baseline-b">First Half Performance Gains Set the Baseline</h2><a href="https://blockonomi.com/bnb-chain-unveils-new-layer-1-as-bnb-tests-key-560-support/" rel="noopener noreferrer nofollow">BNB Chain</a> measured its January to June progress through three core metrics. Block intervals dropped to 450 milliseconds while memory finality fell from 1,125 milliseconds to 650 milliseconds. Benchmark throughput nearly doubled from about 2,800 transactions per second to 5,200.<div class="embed-x"><blockquote class="twitter-tweet">BNB Chain glo <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f199.png" alt="🆙" class="wp-smiley"> in 2026 so farBlock intervals: 750 ms → 450 ms Memory finality: 1,125 ms → 650 ms Benchmark throughput: ~2,800 → ~5,200 TPSH2 goes further, targeting another 2x throughput increase.Catch up on the full roadmap <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f447.png" alt="👇" class="wp-smiley"><a href="https://t.co/jCmjDehLBR" rel="noopener noreferrer nofollow">https://t.co/jCmjDehLBR</a>— BNB Chain (@BNBCHAIN) <a href="https://x.com/BNBCHAIN/status/2075913015157744113?ref_src=twsrc%5Etfw" rel="noopener noreferrer nofollow">July 11, 2026</a></blockquote></div>The network also became more stable during this period. Following the Osaka and Mendel hard fork, re-org occurrences on the BSC <a href="https://moneycheck.com/pi-network-upgrades-mainnet-to-protocol-20-for-utility-focused-smart-contracts/" rel="noopener noreferrer nofollow">mainnet</a> dropped noticeably compared to earlier months.Four engineering features drove most of the improvement. Block Level Access List pre-declares state access patterns to support future parallel processing. Incremental Snapshot speeds up chain synchronization for new or lagging nodes.EVM SuperInstruction reduced interpreter overhead by combining common opcode sequences, which directly boosted throughput. Extended Voting Rules strengthened the fast finality mechanism during adverse network conditions.The BSC Rust client reached full Reth v2.0 compatibility during this window. This included Sparse Trie Cache, Proof V2, and RocksDB support, delivering a twofold performance gain. Middleware also advanced, with the BNB Agent Studio and Agent SDK launching alongside the Middleware Payment Protocol SDK.<h2 id="b-second-half-targets-a-new-architecture-b">Second Half Targets a New Architecture</h2>BNB Chain set three commitments for the second half of 2026. The first goal is doubling mainnet throughput again, building toward a tenfold increase across the wider network over time.The second commitment focuses on isolating application traffic so demand spikes in one area do not degrade performance elsewhere. <a href="https://parameter.io/ethereum-team-transfers-75m-to-kraken-as-gas-limit-hits-60-million/" rel="noopener noreferrer nofollow">Gas fee</a> structures will also be adjusted to lower entry costs for Web2 and Web3 enterprises.These goals connect to active workstreams. BEP-675 implementation, dedicated lane solutions for peak activity, and FOCIL inspired technology for transaction inclusion are already underway. BAL based parallel execution aims to cut block import latency further.Beyond the current stack, BNB Chain is developing a new Layer 1 architecture. It targets over 100,000 transactions per second, sub-50 millisecond preconfirmation, and a TxStream design that removes the public mempool to limit front running.The new chain will include PriorityLane for reserved block space and native privacy features with selective disclosure. Testnet release is planned for late 2026, with mainnet following in early 2027. In its closing statement, BNB Chain said its aim remains building infrastructure that holds up under real use. <a href="https://coincentral.com/justin-sun-sets-2026-timeline-for-tron-quantum-resistant-network/" rel="noopener noreferrer nofollow">Quantum resistant</a> research will continue throughout this period, layering new cryptography on top of existing systems without altering user addresses.The post <a href="https://blockonomi.com/bnb-chain-doubles-throughput-in-h1-2026-sets-sights-on-100k-tps-architecture/" rel="noopener noreferrer nofollow">BNB Chain Doubles Throughput in H1 2026, Sets Sights on 100K TPS Architecture</a> appeared first on <a href="https://blockonomi.com" rel="noopener noreferrer nofollow">Blockonomi</a>.
