But I think it's pointless to guess how many will use it, but rather make the system ready for 10 billion people. The point is that for small transactions, they will be done off-chain. The actual Bitcoin blockchain will only show very large transactions (such as a military purchasing a new space shuttle) or aggregate transactions (i.e. a transaction consisting of multiple smaller transactions done off-chain). There can also be multiple layers of chains creating a tree-like structure. Each chain above will validate the aggregate transactions of the chain below. You can think of the Bitcoin blockchain as the "hypervisor" that manages all the other chains. While your coffee purchase 4 days ago may not be directly visible within the Bitcoin blockchain (the main chain), you can trace it down the sequence of chains until you find it. Same with that fancy dinner your government MP paid for using public funds. You don't have to store a copy of all transactions that occurred for each chain in existence, but rather just the transactions for the chains that you use or are relevant to you. As you see, this kind of system is totally transparent to all users and totally flexible (you can choose your sub chains). The flexibility also allows you to have arbitrarily fast transactions (choose a chain or lightning channel attached to that chain that supports it), and you can enjoy a wide variety of features from other chains, like using one chain that is known to have good anonymity properties. > -----BEGIN PGP SIGNATURE----- > > iQIcBAEBAgAGBQJVTgNcAAoJECpf2nDq2eYjM8AP/2kwSF+HMPR1KdaZsATL4rog > xSS97Q5iEX8StA61jUqHQmpXL5pG6z5DeeKT/liwcMnYnVqOEOLvoVctr3gXfgRz > 9GJeTOlmN5l9xBeX/nWa0A2ql0kWZpYolBS1FwYadWReAD8R0X9UeBd9YXLZNy33 > Ow9JjwRjKHhsuyrlMP8pRDKlGPoa/U+2aW4FwiysMLa0Gu6dbFjTrp3bHw4Fccpi > X0E/aDN68U4FV+lZ4NzkMsBK9VARzmC8KI0DQ540pqfkcnyoYf0VERl/gslPWhfq > t6Rqa7vHHMqFe82lgCd3ji8Qhsz8oBrDS4u4jqwATvgihgImOB6K85JoKmf3y2JS > jByjMGd4Ep0F80Z2MRhi6HuEoRU69uY2u6l9bZxMjzvLX8sG6QTNk3uLMS3ARXcY > JBjZ/g13DXgcRj01fq05CHbCTJYZgTA9pRZTY+ZKH4r0mu86b9ua7hjvyKHS6q54 > uaFmRkNcnKlpCY+fvH/JUdvvmwrA0ETUdHhRyk8vzWIMi+aH4//GwrCmBNRrugzv > 9JtQ1BC+tQqtSX2VkFEhAVISitgkBqurVVlGk18FvVKPFO8cnFS/6NWoPE0WLLzW > 2pTuhEPjdz9UAHD3RW601rb4C0LbuwVlGO4tYBjyqCmk/vBlES2XIjQKctXZLBEy > eLgn3gMwEXUTU6UdGyvb > =RPhK > -----END PGP SIGNATURE----- > > > ------------------------------------------------------------------------------ > One dashboard for servers and applications across Physical-Virtual-Cloud > Widest out-of-the-box monitoring support with 50+ applications > Performance metrics, stats and reports that give you Actionable Insights > Deep dive visibility with transaction tracing using APM Insight. > http://ad.doubleclick.net/ddm/clk/290420510;117567292;y > _______________________________________________ > Bitcoin-development mailing list > Bitcoin-development@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/bitcoin-development > > -- PGP: B6AC 822C 451D 6304 6A28 49E9 7DB7 011C D53B 5647 --20cf301fb60dc72eac0515aa61fc Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

How many individuals and companies do you propose will ever use
Bitcoin (order of magnitude estimates are fine)

Whatever number you select above, please describe approximately how
many lifetime Bitcoin transactions each individual and company will be
capable of performing with a 1 MB block size limit.
I would expect at least 10 billion people (directly or indirec= tly) to be using it at once for at least 100 years. But I think it's po= intless to guess how many will use it, but rather make the system ready for= 10 billion people. The point is that for small transactions, they will be = done off-chain. The actual Bitcoin blockchain will only show very large tra= nsactions (such as a military purchasing a new space shuttle) or aggregate = transactions (i.e. a transaction consisting of multiple smaller transaction= s done off-chain). There can also be multiple layers of chains creating a t= ree-like structure. Each chain above will validate the aggregate transactio= ns of the chain below. You can think of the Bitcoin blockchain as the "= ;hypervisor" that manages all the other chains. While your coffee purc= hase 4 days ago may not be directly visible within the Bitcoin blockchain (= the main chain), you can trace it down the sequence of chains until you fin= d it. Same with that fancy dinner your government MP paid for using public = funds. You don't have to store a copy of all transactions that occurred= for each chain in existence, but rather just the transactions for the chai= ns that you use or are relevant to you.
