Bitok v0.3.19.8 - Security HardeningThis release implements critical security improvements and network reliability enhancements. All changes are backwards-compatible.
Time Warp Attack ProtectionPrevents timestamp manipulation attacks that could artificially lower mining difficulty:
Blocks with timestamps more than 2 hours + 60 minutes ahead of parent are rejected
At difficulty adjustment boundaries, suspiciously compressed timespans are blocked
Soft-fork activation at block 16,000 - warnings only before activation, strict enforcement after
DNS Seed DiscoveryReliable peer discovery for network bootstrapping:
seed1.bitokd.run
seed2.bitokd.run
seed3.bitokd.run
Hardcoded fallback nodes when DNS is unavailable
Privacy-Preserving IP DetectionRemoved all external HTTP service dependencies:
External IP now learned from peers via standard P2P handshake
Manual configuration available via -externalip=X.X.X.X
No connections to third-party services (checkip.dyndns.org, whatismyip.com removed)
Upgrade recommended for all node operators. Nodes running older versions won't have time warp protection after block 16,000.See
SECURITY_FIXES.md for technical details.
