 ## CDDL specification draft
 
 - Created initial CDDL specifications for core Leios components:
-  - Input Blocks with VRF lottery and single IB/slot limits
-  - Endorser Blocks as new aggregation block type
-  - Ranking Blocks as Conway extension with optional certificates

-- Follows crypto-benchmarks implementation approach while maintaining Conway CDDL compatibility
-- Established foundational structures in first draft covering common base components
-- Future iterations will add detailed specifications for design variants including full sharding, overcollateralization, and protocol extensions.

 - Conducted empirical bandwidth measurements using `iperf3` between data centers in North America and Europe
 - Measured bidirectional connections across multiple cloud providers (OVH, AWS, CenturyLink)

+- Results ranged from 95 Mbps to 973 Mbps, depending on geographic distance and the provider
 - Identified 100 Mbps as a conservative lower bound for inter-datacenter connections
 - Observed 5-20% reduction in individual link speeds when multiple simultaneous connections are active.
 
 ## Large-scale network experiments
 
 - Conducted comprehensive experiments using both the 750-node and 10,000-node network topologies with Haskell and Rust simulations
 - Studied transaction and IB throughput limits for realistic scenarios up to 300 TPS and 32 IB/s
