 are the implications to our code.

-Since post number is constrained by max of 288 posts per day in average, that means we have 5 years

 - Besides increasing the maximum number of pieces, a more pressing issue to save bandwidth and

 - Store a dht resource "publickey" containing not only the public key itself but also information
 needed to validate it by a lightweight client. That includes: block hash, block height and partial
 merkle tree inside that block. This resource propagation cannot be sent right after user
 registration for obvious reasons (no block yet, other nodes wouldn't accept the signed dht put).
